Common Bass Boat Battery Setups
The most common setup for a bass boat is: The most common setup we see for bass boats with a 36 volt trolling motor recommends three 12V 50Ah batteries for the trolling motor and one 12V 125Ah battery for your engine starter and other equipment like a fish finder.
Smaller bass boats can manage with fewer batteries: If you were running a 24 volt trolling motor then you could use two 12V 100Ah batteries for the trolling motor and one 12V 125Ah battery for the engine starter and other onboard equipment.
Here are some more in depth examples based on common questions and setups we see
36 volt trolling motor and starter battery
Let’s say you need to power a 36V, 112lb thrust trolling motor (max amp draw of 52A), and you’re looking for a lithium battery for starting your 250hp outboard and running two large depth finders as well. Here’s your best options:
For 36V trolling systems, over 95% of our customers use our Ionic Deep Cycle 12V 50Ah lithium marine battery, which provides plenty of reserve energy.
For the starter battery, our bass boat customers (most of which have 200-250hp 4-stroke motors) typically go with our recommended Ionic Deep Cycle 12V 125Ah lithium marine battery.
24 volt trolling motor and starter battery
Now, let’s say you have a 24V 80lb thrust trolling motor and a 300 Yamaha hpdi; you have 2 batteries for the trolling motor and 2 cranking (perko switch for the cranking), and you’re looking for your best possible lithium set up. What do you need?
For your 24 volt trolling systems, we recommend two Ionic 12V 100Ah Lithium Marine batteries.
For your starter battery, we recommend the Ionic Deep Cycle 12V 125Ah lithium marine battery.
