A reliable battery is essential to a trolling motor. After all, the last thing you want to happen is for your fishing trip to get interrupted or canceled just because of battery failure. If you are concerned that your battery is not going to last very long or you are anxious about how reliable it really is, you might want to consider a 36v 100AH LiFePO4 battery. It is the most powerful option for a 36v 120 lb. thrust trolling motor!
The better battery
A
high-quality lithium battery should provide extended power and over 14 hours of
run time on a 36v marine trolling motor. That makes the 36v 100AH lithium iron
phosphate battery an excellent choice for pro anglers and fishermen, or if you
simply love to spend a lot of time on the water. A single module battery
significantly weighs less and will occupy less space compared to when you
connect three 12v 100AH lithium batteries in a series.
It
is recommended that you use a battery with the right voltage for a thrust
trolling motor than linking lithium batteries in a series. You could even use a
parallel connection to increase its capacity.
Get optimum performance from the battery
Once
you have set up the 36v 100AH battery on your boat, you might want to
know how you can get the best performance out of it. First, you need to make
sure that there is a Battery Management System (BMS), an electronic board that
manages and controls the battery, and protects it from reverse polarity,
overcharging, and short circuiting. It also ensures that the battery is safe to
charge.
The
depth of discharge is worth considering, as it determines the battery’s cycle
cart. A low DoD means the battery will last longer. That said, avoid full
discharges and consider recharging more often between uses. It is okay to
partially discharge a lithium battery, as it has no memory effect. When not in
use, store the 36v 100AH lithium battery safely in a dry and temperate
environment.
