Description
12V 50Ah Lithium Battery — CLI50-12
The Canbat CLI50-12 is a 12V 50Ah lithium battery delivering 640Wh of usable LiFePO4 energy in one of the most compact and lightweight form factors in the Canbat deep cycle lineup. At 14.5 lbs (6.58 kg) with a 196 × 166 × 175 mm footprint, it is purpose-built for applications where physical size and weight are the defining constraints — kayak and small boat trolling systems, compact portable power setups, space-limited auxiliary installations, and any application that demands real deep-cycle lithium performance in a genuinely portable unit.
Despite its compact dimensions, the CLI50-12 delivers 50A continuous discharge, 3,000–5,000 cycle life at 100% depth of discharge, and the same prismatic LiFePO4 cell quality and integrated BMS protection found across the Canbat standard lithium lineup. This is not a downsized consumer product — it is a purpose-engineered compact deep-cycle platform with the same technical standards as the larger models in the range.
It ships free across Canada and the USA, carries a 10-year warranty, and is built with UL 1642 certified cells. For Canada and USA orders, there are no import duties or cross-border complications.
640Wh of Usable Energy — At Just 14.5 lbs
The CLI50-12’s 196 × 166 × 175 mm footprint fits battery compartments and mounting spaces where larger deep-cycle batteries simply cannot go. For kayak fishing setups, small jon boats, compact trailers, under-seat auxiliary installations, and portable power boxes, its physical dimensions open installation possibilities that are not available with standard Group 24 or Group 27 batteries.
A comparable AGM battery at 50Ah nominal delivers approximately 25Ah of usable energy before its depth-of-discharge limit is reached. The CLI50-12 delivers its full 50Ah at 100% usable depth of discharge — twice the accessible energy at a fraction of the weight of an equivalent AGM, with stable voltage maintained throughout the entire discharge cycle rather than declining progressively.
At 14.5 lbs (6.58 kg), the CLI50-12 is light enough to carry in one hand, move between vessels, store in a gear bag, or mount in locations where installation access is limited. For buyers who need dependable deep-cycle lithium performance without the size and weight of a conventional deep-cycle battery, it is the correct specification.
Applications
Kayak & Small Boat Trolling Motors
The CLI50-12 is the preferred trolling motor battery for kayak fishing, canoe, and small boat applications where weight distribution is critical and every pound matters. At 14.5 lbs it is significantly lighter than any comparable AGM trolling motor battery, and its stable flat discharge voltage maintains consistent motor thrust throughout the session — unlike AGM batteries where thrust degrades as voltage declines under load.
Compact Portable Power Systems
For portable power boxes, DIY power stations, and mobile auxiliary power setups, the CLI50-12 provides 640Wh of usable lithium energy in a unit compact enough to carry in a gear bag, store under a seat, or mount in a confined space. Powers 12V fridges, lighting, device charging, and small inverter loads for day trips and overnight outings.
Small Marine Electronics & House Banks
For smaller vessels running a dedicated electronics bank — fishfinder, chartplotter, VHF radio, and navigation lights — the CLI50-12 provides reliable all-day reserve in a compact sealed unit. No off-gassing, no terminal corrosion, and no maintenance in the confined spaces of a small boat’s battery compartment.
Compact RV & Camper Auxiliary Power
For small camper trailers, pop-up campers, and rooftop tent setups with minimal battery compartment space, the CLI50-12 provides an evening’s worth of energy for lighting, fans, and device charging in a unit that fits where larger batteries cannot. Two units in parallel provide 100Ah in the same compact form factor.
Mobile Equipment & Auxiliary Power Systems
The CLI50-12’s compact footprint, stable discharge voltage, and maintenance-free operation make it well suited for commercial and industrial auxiliary power applications where physical space, deployment weight, and long-term reliability are equally important. Mobile traffic control trailers, remote monitoring stations, traffic surveillance systems, robotic platforms and mobile service equipment all benefit from a compact lithium power source that delivers consistent voltage under load without the maintenance overhead of sealed lead-acid alternatives. With 3,000–5,000 cycle life at 100% depth of discharge and no watering, equalization, or service requirements, the CLI50-12 reduces total cost of ownership in deployments where battery replacement and maintenance access are logistically complex.
Auxiliary & Space-Limited Installations
For auxiliary power installations in vehicles, service equipment, mobility applications, and any system where the available battery space is smaller than a standard deep-cycle battery compartment, the CLI50-12’s compact footprint enables lithium deep-cycle performance in installations where no other Canbat deep-cycle model will fit.
12V 50Ah Lithium Battery for Trolling Motors, Marine & Portable Power
The CLI50-12 is Canbat’s ultra-compact deep cycle lithium battery — designed for buyers sourcing a 12V 50Ah lithium battery for kayak trolling motors, small boat marine systems, compact portable power applications, and space-limited auxiliary installations where physical size and weight are the primary constraints alongside reliable deep-cycle performance.
For Canadians sourcing a 12V 50Ah lithium battery, the CLI50-12 ships free with no import duties, is backed by a Canadian technical team, and carries a 10-year warranty. Compatible with all major chargers and solar charge controllers that support a LiFePO4 charging profile. For systems requiring greater capacity, up to four CLI50-12 units can be connected in parallel to reach 200Ah at 12V.
Runtime & Performance
The CLI50-12 delivers 640Wh of usable energy at 12V nominal — all accessible at 100% depth of discharge on every cycle with stable voltage throughout:
| Application / Load | Average Draw | Estimated Runtime |
|---|---|---|
| LED lighting & device charging | 5–8A | 6–10 hours |
| Kayak trolling motor — low speed | ~15–25A | ~2–3 hours |
| Marine electronics (fishfinder, VHF, nav lights) | ~6–10A | ~5–8 hours |
| 12V portable fridge | ~4–8A average | ~6–12 hours |
| Inverter — 100W load | ~9A | ~5.5 hours |
| Camping lighting + fan + devices | ~5–8A | ~6–10 hours |
Runtime figures are based on 100% usable depth of discharge. The CLI50-12 maintains stable voltage throughout the discharge cycle — consistent performance from start to finish, without the progressive voltage sag that reduces motor thrust and equipment performance in AGM batteries.
Series & Parallel Expandability
The CLI50-12 supports both series and parallel connections — up to 4 units in either configuration — allowing the system to scale as energy requirements grow while retaining the compact form factor advantage of each individual unit.
| Configuration | Units | System Voltage | Total Capacity |
|---|---|---|---|
| Single unit | 1 | 12V | 50Ah / 640Wh |
| Parallel x2 | 2 | 12V | 100Ah / 1,280Wh |
| Parallel x3 | 3 | 12V | 150Ah / 1,920Wh |
| Parallel x4 (max) | 4 | 12V | 200Ah / 2,560Wh |
| Series x2 | 2 | 24V | 50Ah / 1,280Wh |
| Series x3 | 3 | 36V | 50Ah / 1,920Wh |
| Series x4 (max) | 4 | 48V | 50Ah / 2,560Wh |
Two units in parallel deliver 100Ah / 1,280Wh — equivalent to the CLI100-12 in capacity, in a dual-unit compact installation that can be distributed across two separate mounting locations if required.

I bought this 50Ah LiFePO4 battery for boat and I am now spending double the time on the water compared to when I had the previous battery! Very satisfied with the quality and I highly recommend this lithium battery to all the skippers out there!
Ben O. –
Awesome battery. Lasted all day on my motor! great service as well.
Morgan K. –
Very pleased with my purchase. I will definitely choose Canbat again for my next lithium battery purchase.
Zac E. –
This battery is what I’ve been searching for. It’s very light and powerful. Perfect for my trailer. Great for our trips!
Martin H. –
The performance of the battery exceeded my expectation. They’re reliable, they were still running after 8hrs. My old one barely gave me a couple of hours before it died.
Luke K. –
Better performance and more efficiency for my speed run on my motorboat. I am guessing I won’t need another battery for at least 10 years.
Chuck N. –
Quick shipping. I received the battery in a matter of days. Powerful and lasting battery.
Mia C. –
By far, the best pricing on lithium batteries in Canada. I’ve been comparing Canbat with other battery suppliers online and found Canbat lithium products to be the most competitive, especially with free shipping. I live in the middle of nowhere in Alberta and shipping to my house would be super expensive if I had to pay for it. The customer service is second to none. I will be buying all my batteries from here from now on!
Justin T. –
The battery was well packed and secured. They also added some gifts inside the package. I received a few pens, a red coffee mug and a wall clock, which was a really nice surprise. For the price I paid for this battery, this was a great deal. I was so close to buying a Chinese battery for about the same price from the battery shop near my house, and I am so glad I didn’t. All of my future battery purchases will be from Canbat and I highly recommend Canbat to everyone!
Kris K. –
I have been living in my RV since house prices became way too unaffordable for my budget (yes, it’s been years). I was in search of some batteries and I came across Canbat on Google. I had to call them because I was unsure of what battery to buy and they gave me some excellent suggestions. Alex spent half an hour on the phone with me and he did not for one second make me feel like I am taking too much of his time. He even recommended a local company that can help me install the batteries in my RV. Great services. Thank god!
Amanda L. –
Great battery. I have a few installed in case of a power outage at my business.
Andy Z. –
I got recommended to Canbat by my mechanic. Shipping was really fast and the product is light. Last week I bought the LiFePO4 battery for my camping equipment. I was amazed that the battery lasted so long. From now on I will bring the battery with me when I go on road trips.

First time hearing CANBAT. I needed a new battery for my trolling motor since my lead acid battery died. They suggested me switching to a lithium battery because it is more efficient and it offers a longer runtime. After talking with them on the phone for 15 minutes I end up ordering one. Took the battery a few days to arrive. My god, the battery is lightweight. I installed it on my trolling motor and went out for a fishing trip with my son. One thing for sure, the charge holds up!
Rafael L. –
Well packaged and delivered in a timely manner.
Blake G. –
Well recommended Lithium battery for all those who love exploring nature and going fishing.
Kate T. –
Just received the battery last week. I am impressed by the performance this lithium produces.
Dickson K. –
I am loving this lithium battery over SLA so far. I am getting twice the run time for my fish finder. A great battery even when temperatures is low.
Dae W. –
This is probably going to make me sound like a bad daughter, but I’ve just recently found out that my dad likes to go fishing in his free time with his friends. He recently bought a motorboat and requires a new battery. I know nothing about fishing, batteries or boats. I came here and Canbat helped me with every question I had and helped me find the right battery. Glad to see how happy my dad is with the power the battery offers.
ShenMing W. –
I am a fisherman for a living and I need the right size to fit on my Terrova. Canbat provided me with the right size and gave me a great quote that I can not deny. Highly recommend their lithiums for any fisherman!
John C. –
I was looking for a battery for my scooter. The 12v 50ah battery fits perfectly and provides great range!
Dave D. –
So far so good the battery I received from Canbat. Very good customer service. I hope the battery lasts as long as they say! Happy to see a Canadian company offering a 10 year warranty.
Henry H. –
I needed to look for a 12V 50Ah battery to back up my power system for my equipment in the garage. Besides using the battery for my equipment, I also take it with me off road and on my camping trips. Works great for both!
Sean W. –
I picked up my batteries I order from their warehouse. We discuss what battery works best for my motor. I bought a 12v 100ah instead of 12v 50ah. Now I got to give this a test! Customer service on the phone and in person was outstanding.
Alvin W. –
I was looking for a battery that can hold up for 4-6 hours of charge and power for my motorboat. Canbat suggested two different batteries for me to pick from. I was convinced to buy lithium over a lead acid battery. I will not go back for lead acid battery. Lithium is way better, although it cost more.
Shawn P. –
After watching one of my favourite YouTubers “Vancity Vanlife”, he purchased batteries from Canbat. I am here now and very satisfied with the lithium batteries they offer. Thanks a lot!
Dan Q. –
Wow, I am amazed how quickly they contacted me when I left them an e-mail with questions about lead acid and lithium batteries. Took me a few days to decide which battery to buy. No regrets.
Bart S. –
I quit my job last month, I’ve been looking for a new long last battery for my van. I started a new hobby which I drive around the region and camp in my van and explore outside my box. Did my research and I came across Canbat, and I bought their last 12v 200ah in store. I was lucky!
Gram K. –
Just received the lithium battery package today from Canada Post. The battery was really light and well package. I ran a quick test on the voltage of the battery and installed it on my motor. Fits well, now off to the river to test out the power and life span.
Andrew L. –
Bought a lithium battery from Canbat a few months ago for my work van. It has been solid and provides great power at the job sites every day.
Lenny P. –
Recently bought a lithium battery from Canbat and it provides a great runtime. I run the fridge in the car and the heater on all night. I have no issue with the battery power. Great product!
Ken C. –
After consulting with Canbat I picked the 12v 100ah over the 50ah. I am very pleased with the battery performance on my motor. I usually go fishing often with the boat and the battery lasts me a long time. I think I can use this battery again the next day without charging.
Ian B. –
Great power performance source for my work van. Lasted me throughout the whole day at work.
Zach V. –
Picked up my brand new battery in store. They have fair pricing. Too bad they don’t sell lithium battery chargers. They told me they will be carrying them soon!
Beny N. –
I bought the wrong battery size for my scooter. Luckily it is the right size for my grandmother’s wheelchair. Ends up working really well for the wheelchair. Last a lot longer than the old battery she had. At least my grandma’s happy I guess lol. I explained what happened to Canbat and they were so understanding and offered me a discount on the second battery. Thank you!
Lane K. –
Fair price and amazing product. I installed the battery on my quantum power chair. Long-lasting battery indeed. This is why you buy Canadian products!
Brett K. –
Came here after I watched this YouTuber who lives in his own RV. He bought a lithium battery and installed it in his RV and he ran it the whole day without a problem. Been following him since day 1, so I preordered one. Hope it comes in soon! very excited!!!
Jake T. –
Best prices for the quality you get! These batteries are the real definition of long lasting.
Petar S. –
The greatest purchase I made this year (aside from beer). I used the batteries to power my ARB fridge and freezer for more than 30 hours. I am one happy customer!
Leo A. –
Great battery to charge multiple electronic devices at the same time. The voltage on the battery was very constant and did not drop suddenly like my old AGM battery.
Ricky L. –
Learned something new today. I can connect two batteries to have a higher amperage instead of one big battery. Just purchased 2 12v 50ah lithium batteries! They are definitely going to be super light to carry for an old guy like me!
Harrod T. –
I have an electric motorboat and I was using an SLA battery 12v 50ah. The battery was too heavy and whenever I used it, the voltage was continuously dropping. I also noticed I was experiencing some slowness with the boat. I recently upgraded to a Canbat 50Ah lithium battery and it was 3 times lighter than my old lead-acid battery. Power voltage and speed performed greatly. Now I can relax knowing I’ll have enough power throughout the day.
Travis S. –
My old lead-acid battery died on my scooter. I just upgraded to Canbat lithium 50ah and it revived my scooter.
eric@canbat.com –
Great replacement battery for my electric motor. Hopefully, it will last as long as my old lithium 12v 50ah battery.
Tom H. –
I recently upgraded from lead-acid to lithium technology. Pricing was a bit more expensive but the performance these batteries can deliver is incredible. I can easily carry the lithium 12v 50ah battery around at age 70.
Leon A. –
I purchased 2 premium Lithium batteries for both of my E-Scooters. They’re long-lasting. My wife and I spend the day on the scooter for our date. Definitely worth the investment.
Larry B. –
Great pre-order pricing. I had to buy 2 lithium 12V 50ah batteries for my work site. Arrived quicker than they said it would.
Doug B. –
I was searching for Lithium deep cycle batteries to upgrade the solar power in my RV. I contacted Canbat and they suggested going for lithium batteries over lead acid because they have a longer life span and better performance. The LiFeP04 did not disappoint us and we are very excited.
PAULINE M. –
Je viens d’installer la batterie dans mon van aménagé, et je suis bluffé par la durabilité et qualité des batteries Canbat! Elle tient la route pour tous mes appareils : frigo, lumières, et même mon ordi.
Omar G. –
J’ai acheté et configuré trois de ces batteries en série pour alimenter ma Terrova, et celle-ci fonctionne maintenant toute la journée sans problème. MERCI CANBAT !
Jean S. –
J’ai acheté cette batterie pour remplacer une batterie plomb-acide de groupe 31. Elle est beaucoup plus légère et plus puissante. Je l’utilise pour alimenter un Humminbird Helix 15 et Megalive, et ça fonctionne à merveille. Après un voyage de 5 ou 6 heures, la batterie n’a perdu qu’environ 15 %. J’ai également acheté trois batteries de 100 Ah pour mon Ultrex Quest, et elles sont tout aussi impressionnantes.
Chris T. –
J’adore ces batteries. C’est mon deuxième ensemble pour mon nouveau bateau. Le premier ensemble fonctionne toujours très bien sans aucun problème. J’apprécie de pouvoir voir l’état de charge des batteries via l’application sur mon iPhone.
