A trolling motor battery set up is a battery, a box to hold it, and clean connections to the motor and the charger. Get those parts right and the motor runs all day; get the box wrong and the battery slides, the terminals corrode, or the lid will not shut. The steps below show the order to work in.

The quick answer
Pick a 12V deep cycle battery for the motor, set it in a box made for its group size, and connect the motor leads to the terminals with the breaker or fuse in line. The boxes here fit Group 24 to 31 batteries: the KELZENO and AmarinePlay boxes add USB ports, a voltmeter and a breaker, while the peastorm steel and stainless boxes are plain lockable boxes. Check the charge before launch, and top the battery up at the dock.
Step 1: Match the battery to the motor
Start with the motor manual: it gives the voltage and the battery type the motor needs. The boxes here are built for 12V systems, and the KELZENO power center (on Amazon) suits both 12V and 24V deep cycle batteries. Group size sets the fit: the peastorm steel box is made for Group 24, the stainless box adjusts from Group 24 to 31, and the AmarinePlay box fits Group 24/27/31 and 27/29 marine batteries. Measure the battery before ordering, as the peastorm makers state. See what type of battery for trolling motor for the battery types in plain terms.
Step 2: Put the battery in the box
Set the battery in the box with the terminals up and the lid able to shut. The KELZENO box uses nano adhesives to keep the battery from shifting, and the peastorm boxes have fixing holes in the bottom with screws included, so the box can be fixed to the boat. The AmarinePlay box has a strap to hold the battery steady and a lid that snaps shut for a good seal. The AmarinePlay maker states the battery can be charged without removing the lid.
Step 3: Connect the motor, charger and gear
Connect the motor leads to the battery terminals first, then the charger, then any small gear. The KELZENO box connects the trolling motor through a 50A Anderson-style quick connector, and the AmarinePlay box powers fish finders, phones and lights through two USB ports and a 12V/10A socket. A breaker sits between the battery and the load: the KELZENO box has a 10A resettable circuit breaker with fuse protection, and the AmarinePlay box has an overload circuit breaker with auto cut-off. Keep the terminals clean and tight and the cables out of bilge water. See the best battery cable for trolling motor picks for cables made for this job.
Step 4: Check the charge before launch
Check the battery voltage before the boat leaves the dock. The KELZENO box has an LCD voltmeter and the AmarinePlay box has a voltmeter display, so the voltage and charge status show without opening the box. The plain peastorm boxes have no voltmeter stated, so check those batteries with a separate meter. Top the battery up at the dock, and check the lid and fixings before launch. See marine battery maintenance for keeping the battery ready between trips.
The gear for the set up
The boxes below handle the steps above: the power centers hold the battery, watch its voltage and connect the motor, while the plain boxes hold the battery and lock it shut.

How to choose the best trolling motor battery set up
Match the box to the battery group
Group size is the first filter: a Group 24 battery fits all the boxes here, a Group 31 battery fits the stainless peastorm box and the AmarinePlay box, and the steel peastorm box takes Group 24 only. Measure the battery first, as the peastorm makers state, and compare the capacity sizes: 11 by 7.8 by 11 inches for the steel box and 14 by 7.8 by 10 inches for the stainless box.
Decide how much power center the set up needs
A plain box suits a motor-only set up: the peastorm boxes hold the battery and lock shut, with no ports to wire. A power center suits a boat that also runs a fish finder, lights or phones: the KELZENO box adds USB-C PD 30W, QC3.0 18W and a 12V socket, and the AmarinePlay box adds two USB ports and a 12V/10A socket. The voltmeter on the power centers shows the voltage without opening the lid.
Check the safety gear in the box
A breaker protects the set up from overload and short circuit: the KELZENO box states a 10A resettable circuit breaker with fuse protection, and the AmarinePlay box states an overload circuit breaker with auto cut-off. The plain boxes state a lockable cover, rubber-ring protected holes and bottom fixing holes with screws. A box with no breaker stated needs one added in line with the motor leads.
FAQ: power away from the grid
What size battery box do I need for a trolling motor battery?
Measure the battery and match its group size: the boxes here fit Group 24 to 31, with the steel peastorm box made for Group 24 only and the stainless box adjusting from Group 24 to 31. Compare the capacity sizes, 11 by 7.8 by 11 inches for the steel box and 14 by 7.8 by 10 inches for the stainless box, against the battery size.
Can I charge the battery without taking it out of the box?
On the AmarinePlay box, yes: the maker states the battery can be charged without removing the lid. On the plain peastorm boxes, open the lid to reach the terminals.
Do I need a circuit breaker in a trolling motor battery set up?
Yes. The KELZENO box states a 10A resettable circuit breaker with fuse protection, and the AmarinePlay box states an overload circuit breaker with auto cut-off. The plain boxes state no breaker, so one must be added in line with the motor leads.
What does the voltmeter on a battery box show?
It shows the battery voltage and charge status in real time. The KELZENO box has an LCD voltmeter and the AmarinePlay box has a voltmeter display with a battery power meter, so the charge can be checked without opening the lid.
Will a Group 31 battery fit these boxes?
It fits the stainless peastorm box, which adjusts from Group 24 to 31, and the AmarinePlay box, which fits Group 24/27/31. The steel peastorm box is made for Group 24 only. The KELZENO box suits 12V/24V deep cycle batteries, with no group size stated, so check the battery size against the box first.
