What type of battery for trolling motor use is a deep-cycle battery, and the listings cited here point to a lithium iron phosphate battery as the pick for a boat. A trolling motor draws power steadily for hours, so the battery must give up its charge slowly and recharge cycle after cycle. This guide explains the types, the figures that matter and the gear that fits the job.

The quick answer
A 12V deep-cycle battery runs a trolling motor, and a 12V LiFePO4 battery is the type the listings cited here back with the strongest figures. The GOKWH unit lists 12.8V 120Ah and 1536Wh with a 100A BMS and up to 4000 deep cycles, and the Litime unit lists 12V 100Ah and 1280Wh with a 100A BMS and 4000+ cycles at 100% DOD. The GOKWH and Litime units expand to 51.2V, and each lists low-temperature protection. The NOVINO cable kit extends (on Amazon) the battery cable to the motor with 6 feet of 8 gauge wire rated for 55 amps. See the batteries guides for the category.
The gear for a trolling motor battery
The battery type sets the hours on the water, and the cable kit carries the power from the battery box to the motor, so the gear below covers the battery and the cable.

What type of battery for trolling motor: how to choose
Match the voltage to the motor
Trolling motors run on 12V or 36V, and the battery must match the motor. The Litime listing says its battery suits 12V to 36V motors. The GOKWH unit expands to 51.2V in a 4S4P layout, and the Litime unit expands to 51.2V in a 4P4S layout. Check the motor label for the voltage before you buy.
Match capacity to the hours on the water
Capacity in amp-hours sets how long the motor runs. The GOKWH unit lists 120Ah and 1536Wh, and the Litime unit lists 100Ah and 1280Wh. The GOKWH unit lists up to 4000 deep cycles, and the Litime unit lists 4000+ cycles at 100% DOD and lasts 10 years. A bigger capacity gives more hours, so match the amp-hours to the time you plan to spend on the water.
Check the cable and the protections
The cable between the battery and the motor must carry the current without power loss. The NOVINO kit gives 6 feet of 8 gauge wire rated for 55 amps, with connect hardware and safe electrical tape. The GOKWH unit lists 20+ BMS safeguards and low-temperature protection that stops charging below 0°F and discharging below -4°F. The Litime unit lists ABYC E-13 standard protection, a BMS with triple protection and low-temperature protection that stops charging below 32°F and discharging below -4°F. See the LiFePO4 batteries guides for more.
Check the warranty and the weight
A stated warranty term says how long the maker stands behind the battery. The GOKWH unit carries a 5 year warranty, and the NOVINO cable kit carries a 2 year warranty, while the Litime and MARSENERGY listings state no warranty term. Weight matters on a boat: the GOKWH unit weighs 24.0 pounds and the Litime unit weighs 22.16 pounds, and the Litime listing says its battery is 64% lighter than a 12V 100Ah lead-acid battery. Check the figures in the listing before you buy.
FAQ: power away from the grid
What type of battery is best for a trolling motor?
A 12V deep-cycle LiFePO4 battery. The GOKWH unit lists 12.8V 120Ah and 1536Wh, and the Litime unit lists 12V 100Ah and 1280Wh, each with a 100A BMS. Lead-acid batteries work too, but the Litime listing says its battery is 64% lighter than a 12V 100Ah lead-acid battery.
What capacity should I pick for a trolling motor?
Match the amp-hours to the hours on the water and the motor draw. The GOKWH unit lists 120Ah and the Litime unit lists 100Ah, and each expands in parallel: the GOKWH unit reaches 480Ah in a 4S4P layout and the Litime unit reaches 400Ah in a 4P4S layout.
Can I use a car battery for a trolling motor?
The listings cited here are deep-cycle batteries, not car starting batteries. The Litime listing says its battery is for energy storage, not for starting batteries, golf carts or jacks. A deep-cycle battery is built to give up its charge slowly over hours, while a starting battery is built for short bursts.
How long does a trolling motor battery last?
The GOKWH unit lists up to 4000 deep cycles, and the Litime unit lists 4000+ cycles at 100% DOD and lasts 10 years. The Litime listing says AGM batteries last 3 years and 200 to 500 cycles. The NOVINO cable kit carries a 2 year warranty, and the GOKWH unit carries a 5 year warranty.
