Description
12V 150Ah Lithium Battery — CLI150-12
The Canbat CLI150-12 is a 12V 150Ah lithium battery delivering 1,920Wh of usable LiFePO4 energy in a standard Group 31 footprint — built for RV owners, boaters, van builders, and off-grid system designers who need more than entry-level capacity without stepping up to a larger, heavier battery format. At 35 lbs (15.8 kg) with 150A continuous discharge and 3,000–5,000 cycle life, it delivers significantly more usable energy than comparable AGM batteries in the same installation space, with maintenance-free operation and full series and parallel expandability.
For RV systems running multi-day off-grid stays, marine house banks powering extended passages, and van builds sustaining refrigeration and accessory loads, the CLI150-12 provides the energy density to extend autonomy, reduce recharge frequency, and support inverter loads that smaller batteries cannot sustain — all in a footprint that installs directly into any standard Group 31 tray or enclosure.
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.
1,920Wh in a Standard Group 31 Footprint
Group 31 is one of the most widely used battery formats in RV, marine, and off-grid applications. The CLI150-12 fits any standard Group 31 tray, hold-down, and battery compartment — no new enclosures, no modified mounting hardware, no changes to existing installation infrastructure.
What changes is what that footprint delivers. A standard Group 31 AGM battery typically provides 100Ah nominal capacity — but only around 50Ah of usable energy before the depth-of-discharge limit that prevents premature degradation. The CLI150-12 delivers 150Ah at 100% usable depth of discharge — substantially greater usable capacity than a comparable Group 31 AGM in the same physical space. That difference translates directly into longer off-grid stays, fewer generator runs, and more reliable overnight autonomy.
At 35 lbs (15.8 kg), the CLI150-12 also weighs roughly half what a Group 31 AGM battery weighs — typically 60–70 lbs — reducing chassis load, improving fuel efficiency in mobile applications, and making installation significantly more manageable.
Applications
RV Extended Boondocking & Off-Grid Travel
For RV owners who regularly spend multiple nights off-grid without shore power, the CLI150-12 provides the overnight reserve to run a 12V fridge, lighting, a diesel heater, and small appliances without hitting a low battery cutoff. Its 1,920Wh of usable energy delivers more days between generator runs and more flexibility in campsite selection.
Marine House Banks
On sailboats, powerboats, and fishing vessels where the house bank powers navigation electronics, VHF, autopilot, refrigeration, bilge, and lighting through the night, the CLI150-12 provides significantly more reserve than a Group 31 AGM in the same compartment. Sealed, maintenance-free, no off-gassing in enclosed spaces, and no terminal corrosion in marine environments.
Van Builds & Overland Systems
For Sprinter, Transit, and Promaster conversions and serious overland rigs where available space limits battery count, the CLI150-12 delivers high energy density in a single Group 31 unit. Runs fridges, lighting, inverter loads, diesel heaters, and charging systems through multi-day off-grid trips without the weight and complexity of multiple smaller batteries.
Off-Grid Solar & Cabin Systems
For smaller off-grid solar installations at cabins, hunting camps, and remote properties, the CLI150-12 provides enough overnight reserve to maintain essential loads through extended periods of low solar production — lighting, communications, water pump, and security systems — without oversizing the battery bank.
Backup Power & Inverter Systems
The CLI150-12’s 150A continuous discharge rating supports inverter loads up to approximately 1,800W — sufficient for small appliances, power tools, medical devices, and communications equipment. Paired with a quality inverter, it provides meaningful backup power capacity for essential loads during grid outages.
12V 150Ah Lithium Battery for RV, Marine & Off-Grid Systems
The CLI150-12 is Canbat’s compact high-capacity standard deep cycle lithium battery — designed for buyers sourcing a 12V 150Ah lithium battery for RV, marine, van, and off-grid applications who need serious runtime from a standard Group 31 footprint without stepping up to larger commercial battery formats. One of the most space-efficient ways to deploy high-capacity lithium energy storage in a familiar, widely compatible format.
For Canadians sourcing a 12V 150Ah lithium battery, the CLI150-12 ships free with no import duties, is backed by a Canadian technical team, and carries a 10-year warranty. Compatible with all major inverter/charger brands and solar charge controllers that support a LiFePO4 charging profile. For installations in unheated environments or cold climates where charging below 0°C is required, the CLI150-12LT offers the same capacity with an integrated heating system.
Runtime & Performance
The CLI150-12 delivers 1,920Wh of usable energy at 12V nominal — all accessible at 100% depth of discharge on every cycle. A standard Group 31 AGM battery, limited to approximately 50% usable depth of discharge, would need a nominal rating of 300Ah to approach this usable output:
| Application / Load | Average Draw | Estimated Runtime |
|---|---|---|
| LED lighting & low-draw electronics | 5–10A | 15–30 hours |
| 12V fridge + lighting | ~15–20A | ~7–10 hours |
| Inverter — 500W load | ~42A | ~3.5 hours |
| Inverter — 1,000W load | ~83A | ~1.8 hours |
| Marine house bank (nav, fishfinder, VHF, lights) | ~10–15A | 10–15 hours |
| Diesel heater + cabin lighting | ~8–12A | ~12–18 hours |
| RV overnight (fridge + heating + lighting) | ~20–30A | ~5–7 hours |
Runtime figures are based on 100% usable depth of discharge. The CLI150-12 delivers its full 150Ah on every cycle with stable voltage throughout — no derating and no reserve capacity restrictions.
Series & Parallel Expandability
The CLI150-12 supports both series and parallel connections — up to 4 units in either configuration — for systems that require greater capacity or higher system voltage as energy requirements grow.
| Configuration | Units | System Voltage | Total Capacity |
|---|---|---|---|
| Single unit | 1 | 12V | 150Ah / 1,920Wh |
| Parallel x2 | 2 | 12V | 300Ah / 3,840Wh |
| Parallel x3 | 3 | 12V | 450Ah / 5,760Wh |
| Parallel x4 (max) | 4 | 12V | 600Ah / 7,680Wh |
| Series x2 | 2 | 24V | 150Ah / 3,840Wh |
| Series x3 | 3 | 36V | 150Ah / 5,760Wh |
| Series x4 (max) | 4 | 48V | 150Ah / 7,680Wh |
Start with a single unit and expand as your system grows — the CLI150-12’s modular architecture supports the full range of 12V, 24V, 36V, and 48V system configurations without redesigning the installation.

Battery Management System and Bluetooth Monitoring
The CLI150-12’s integrated BMS manages cell-level protection and balancing automatically — no external battery management required.
- Over-discharge protection — prevents cell damage from excessive depth of discharge
- Over-charge protection — disconnects at the correct voltage ceiling
- Short circuit and over-current protection — responds within milliseconds
- High-temperature cutoff — protects cells during charging in hot environments
- Cell balancing — maintains consistency across the prismatic cell groups over thousands of cycles
The optional Bluetooth add-on connects the battery to the free Canbat BT app, available for iOS and Android. Monitor state of charge, voltage, current, and cell temperature in real time — useful for tracking system performance in RV, marine, and off-grid installations where direct battery access is limited.
System Compatibility and Installation
The CLI150-12 is compatible with any inverter/charger, solar charge controller, or AC charger that supports a LiFePO4 charging profile. When replacing lead-acid batteries, verify that the charging system’s voltage settings are configured for lithium — incorrect lead-acid charge profiles will undercharge the battery or stress the cells over time.
For alternator charging in vehicles or vessels, a DC-DC charger is recommended to deliver correct LiFePO4 charging parameters and protect the alternator from the battery’s high charge acceptance rate. M8 terminals with bolts are included. The battery installs upright or on its side in any standard Group 31 tray or enclosure.

I love how light this battery is compared to my previous lead-acid. Batteries arrived from Vancouver to Toronto in 4 days and they’re customer service has been great.
Andrew L. –
I was deciding on whether to go with the 100ah or 200ah lithium battery for my 5 wheel travel trailer with a 320 watt Solar panel system. I came across this 150ah lithium size which I felt was perfect for me. I have been using it for a few months now and its been serving me well. its a lot lighter than my lead-acid battery.
Julian W. –
Bought two of these 150Ah batteries and connected them in parallel for my RV. I have tested the batteries before installing them and I was getting more capacity than stated, which is a bonus. I’ve had the batteries for a couple of weeks now and they’ve been working flawlessly. Since my upgrade from lead acid to lithium, I have never ran out of power and that makes my wife happy! High recommend these batteries for RV.
Margaret P. –
This is a perfect 150Ah lithium battery as an upgrade from lead acid. I had a 100Ah lead acid and my lights never last me the entire night. I’ve also had days where the food in my fridge went bad because we continuously ran out of power. As a result, my hubby and I used to get frustrated and we would fight over it. This new 150Ah RV lithium battery we installed gives us a couple of days before requiring a recharge. For the value these batteries provide, I honestly think they’re underpriced! Once we save some more money, we are buying another one and putting it in parallel. This would give us an additional couple of days of power.

We build portable backup power boxes and rent them out to shows and events. Our boxes come in different sizes and each size requires a different size battery. I am so impressed by the variety of 12V lithium batteries Canbat has to offer. We’ve bought and tested the 100Ah, 150Ah and 200Ah. They are all great and very light, which makes our backup power more portable. Excellent company, high-quality batteries, and excellent customer service.

This is the best price in the market for a 150Ah lithium battery. You can’t find a price per amp with this quality anywhere else in Canada. This is the second battery I’m buying and the battery works great. Highly recommended for RV.

I would liked to have given this 150 amp/hr battery 5 stars, however I am giving CanBat 3 stars for falling down on 3 things.
1) Shipping and tracking across Canada sucks, 2 stars at best. They need a better distribution network across the country. At least something in Ontario to cover central and east.
2) Documentation with battery on arrival… none, zero stars. Come on really what would it take to put a document in the box?
3) Connection hardware… bolt too short, 1 star. By the time you try to make more than one connection at the terminal you have run out of usable bolt thread. Guess these guys don’t really know much about RVs. Should be given a choice on ordering. In my case I tossed the short bolt and replaced it with a stud long enough to handle the extra wire lugs.
Once you get past these 3 short comings you find a well made battery at a great price. I used this one battery to replace 2 lead acids and saved considerable space & weight. I am likely to buy and recommend this product to my friends and family.

This is by far the best RV lithium battery in Canada that I have tested.
James N. –
I was in the market for a 12V lithium battery. The 100Ah is too small while the 200Ah is too big. This 150Ah battery is perfect and I noticed that this size is not available anywhere else. I consider this a great buy if you’re stuck in a situation like mine.
Harps D. –
Got this lithium battery for my new 9.9 Yamaha outboard and I love it. The battery is super powerful and very light. Free shipping and the battery arrived in 4 days, which is much faster than expected.
Michel O. –
Great Product works flawlessly, the service at Canbat is outstanding! Got all the information I was looking for to help me make my decision and chose the 150Ah for my needs. They delivered it to my door an hour after I purchased it! Highly recommend Canbat and their products very dedicated bunch.
