Description
36V 50Ah Lithium Battery — CLI50-36
The Canbat CLI50-36 is a purpose-built 36V 50Ah lithium iron phosphate battery designed for demanding deep cycle applications — most commonly 36-volt trolling motor systems, marine electronics, golf carts, and off-grid power installations. With 1,800Wh of usable energy in a single compact unit, it replaces the traditional bank of three 12V lead-acid batteries with a significantly lighter, lower-maintenance alternative that delivers consistent voltage from the first amp to the last.
Built on LiFePO4 chemistry — the most thermally stable and cycle-proven lithium format available — the CLI50-36 is rated for 3,000–5,000 full charge/discharge cycles at 100% depth of discharge. It ships free across Canada and the USA carries a 10-year warranty, and is built with UL 1642 certified cells. For Canadian buyers, there are no cross-border duties or import complications.
36V Trolling Motor Battery
The CLI50-36 is one of the most capable 36V trolling motor batteries available to Canadian anglers. Its 50Ah capacity delivers approximately 1,800Wh of usable energy — enough to run a high-draw trolling motor for a full day of fishing without anxiety about range.
Unlike AGM batteries, the CLI50-36 maintains stable voltage under load throughout the discharge cycle. Lead-acid batteries lose voltage progressively as they deplete — you feel this as the trolling motor gradually slowing down through the day. LiFePO4 chemistry holds a flat voltage curve, meaning your motor runs at consistent power from the first cast until the battery reaches its cutoff threshold.
Compatible with all standard 36-volt trolling motor platforms including Minn Kota (Ultrex, Terrova, Riptide), Garmin Force, Newport, and others. M8 terminal hardware is included.
| Motor Draw | Speed Setting | Estimated Runtime |
|---|---|---|
| 10–12A | Slow troll | ~4–5 hours continuous |
| 15–18A | Moderate / cruising | ~3–3.5 hours continuous |
| 20–25A | Higher speed | ~2–2.5 hours continuous |
| Mixed use | All-day fishing | 8–12 hours real-world |
Runtime based on 100% usable depth of discharge. Actual results vary by motor model, thrust level, and conditions.
36V Golf Cart Battery
The CLI50-36 is a direct lithium upgrade for 36-volt golf cart systems. Standard golf cart packs — typically six 6V or three 12V lead-acid units — carry substantial weight and require regular maintenance: terminal cleaning and equalization charges. Replacing that pack with a single CLI50-36 eliminates all of that.
The weight reduction is immediate and meaningful. Three 12V AGM batteries commonly weigh 180–210 lbs combined. The CLI50-36 weighs approximately 36 lbs — a reduction of over 140 lbs that improves range, reduces wear on the drivetrain, and transforms how the cart handles on hills and uneven terrain.
The integrated BMS handles all cell-level protection with no external management required. Up to four CLI50-36 units can be connected in parallel to scale capacity to 36V 100Ah, 150Ah, or 200Ah. Series connection to increase voltage is not supported.
Runtime & Performance
Understanding what 1,800Wh means in your specific application helps set accurate expectations before you buy:
| Application | Average Draw | Estimated Runtime |
|---|---|---|
| Trolling motor — slow troll | 10–12A | ~4–5 hours |
| Trolling motor — moderate speed | 18–22A | ~2.5–3 hours |
| Trolling motor — high speed | 30A+ | ~1.5 hours |
| Golf cart — 18 holes | Varies | Multiple rounds |
| Off-grid inverter (400W load) | ~11A | ~4.5 hours |
| Marine electronics (fishfinder, nav) | 3–5A | 10–15+ hours |
These figures reflect the CLI50-36’s full 50Ah — the complete usable capacity. AGM batteries should not be regularly discharged below 50% depth of discharge to avoid accelerated degradation, meaning real-world usable capacity is significantly reduced over time. The CLI50-36 delivers its full 50Ah on every cycle.
One 36V Lithium Battery vs. Three 12V Lead-Acid Batteries
Most 36V marine and golf cart systems have historically run on three 12V batteries wired in series. Upgrading to a single 36V lithium unit changes the system fundamentally — not just the chemistry.
| CLI50-36 (36V LiFePO4) | 3× 12V AGM Lead-Acid | |
|---|---|---|
| Weight | ~36 lbs (16 kg) | ~180–210 lbs (82–95 kg) |
| Usable Capacity | 50Ah (100% DoD) | Varies by configuration — degrades significantly over time |
| Cycle Life | 3,000–5,000 cycles | 300–500 cycles |
| Wiring | Single unit — simple | 3 batteries in series |
| Maintenance | None required | Terminal cleaning, equalization charges |
| Voltage Under Load | Flat curve — consistent power | Drops progressively |
| Lifespan | 10+ years | 3–5 years |
| Long-Term Cost | Lower (fewer replacements) | Higher (frequent replacement) |
The weight reduction is especially significant on fishing boats. Multiple customers have reported shedding over 100 lbs from their setup — weight that previously sat in the bow or stern, affecting trim, fuel efficiency, and overall handling.

Battery Management System & Bluetooth Monitoring
Every CLI50-36 includes an integrated BMS that actively monitors and protects the cell stack during both charge and discharge. There is no external battery management required — the BMS is built in and operates automatically.
- Over-discharge protection — prevents cell damage from excessive depth of discharge
- Over-charge protection — disconnects at the correct voltage ceiling
- Short circuit protection — responds within milliseconds
- Low-temperature charge cutoff — prevents charging in sub-zero conditions that damage lithium cells
- Cell balancing — maintains consistency across internal cell groups over thousands of cycles
The optional Bluetooth add-on connects the battery to the free Canbat app (iOS and Android). From your phone, you can monitor real-time state of charge, voltage, current draw, and charge status — useful on the water when you want accurate runtime data without guessing.
Seasonal Storage & Long-Term Shelf Life
LiFePO4 chemistry has a substantially lower self-discharge rate than lead-acid — typically losing only 2–3% of charge per month at room temperature. For long-term storage, Canbat recommends charging the CLI50-36 to 80–100% state of charge before storing in a cool, dry environment.
For seasonal equipment — fishing boats, golf carts, and RVs stored over winter — this is a meaningful practical advantage. Before storage, charge the battery to 80–100% state of charge, then disconnect and store. No trickle chargers, no battery tenders, and no equalization cycles are required before the next season.
Canadian Supply, Support & Warranty
Canbat is a Canadian battery company. The CLI50-36 ships free to any address in Canada and the USA with no import duties or cross-border complications on their orders. There are no cross-border duties, no import delays, and no currency conversion markup.
The CLI50-36 is backed by a 10-year warranty and supported by a Canadian technical team available by phone, email, and live chat. Warranty claims are processed directly with Canbat — no third-party distributors, no overseas support queues.
