36V 60AH Group 31 LiFePO4 Deep Cycle Battery

As a rough guide, divide the 60Ah capacity by the motor's draw in amps. That works out to about 4 hours at 15A, about 3 hours at 20A and about 2 hours at 30A. Actual runtime depends on speed, wind, current and temperature.

Yes. It uses a standard Group 31 case, 13.07 in long, 6.93 in wide and 8.9 in tall, so it fits Group 31 battery boxes and trays. Check the terminal clearance in your compartment before installing.

Charge time is roughly the capacity divided by the charger's output: about 5 to 6 hours from empty at the 10-12A standard charge current, or about 2 hours at the 30A maximum continuous charge current. Use a charger with a 36V LiFePO4 profile (43.2V charge cut-off).

It is rated for more than 3,000 cycles at 100% depth of discharge and more than 6,000 cycles at 80% depth of discharge.

The data sheet lists a charging range of -4°F to 131°F (-20°C to 55°C) and a discharging range of -4°F to 140°F (-20°C to 60°C). The battery has built-in heating.

It carries an IP67 rating: dust-tight and protected against temporary immersion in water. Still mount it in a battery box or secured tray, as you would any marine battery.

A 60-month (5-year) free replacement warranty and 120 months (10 years) of total pro-rata coverage.

Both are Pro-Guide 36V LiFePO4 batteries with the same Group 31 footprint. The 36VM60 holds 60Ah (2,304Wh) in a standard 8.9 in tall case, while the 36VM75 holds 75Ah (2,880Wh) in a Group 31 Tall case that is 10.83 in tall.

Deep-cycle lithium batteries are designed to provide steady power over long periods and handle repeated charge and discharge cycles. They are ideal for trolling motors, marine electronics, RVs, solar systems, fishing electronics and other applications that require sustained power.

In many applications, yes. A LiFePO₄ battery can replace a similarly sized lead-acid or AGM battery while offering more usable capacity and less weight. Always verify voltage, physical dimensions, terminal configuration and charging compatibility before replacing your existing battery.

Use a charger with a LiFePO₄-compatible charging profile that matches the voltage of your battery. Some existing chargers may be compatible, but the charging specifications should always be checked before use.

Certain Pro-Guide lithium batteries can be connected in series or parallel depending on the model. Batteries used together should be the same model, capacity, age and state of charge. Always check the specifications for the individual battery before building a battery bank.

Because LiFePO₄ batteries do not contain free-flowing liquid like flooded lead-acid batteries, they offer significantly more installation flexibility. Follow the mounting recommendations provided for your specific battery.
