FAQ's

Why use Lithium batteries for a trolling motor?

Lithium (LiFePo4)batteries are perfect for trolling motors because they offer high capacity storage per pound (nearly 4x), consistently high power at same voltage (means higher operating efficiency), much longer lifespan (up to 10x and more), less weight (half), longer shelf life and rapid efficient charging (20% more efficient), availability of 95% of rated battery amperage instead of 50-60% available in lead acid. Some even offer a Bluetooth app to your phone so you can see exactly how much power you have left at any time.

What are the major components of a LiFePO4 battery?

A LiFePO4 battery has two primary components, the LiFePO (lithium iron phosphate) cells and the Battery Management System (BMS). Both are inside a sealed battery case. The quality of the cells and BMS are key to the longevity and performance of the battery. LiFePO cells are wired in parallel to form a single module producing 3.2 volts. Four of these modules are connected in series to form a rated 12.8 volt LiFePO4 battery; eight for a 25.6 (24) volt battery. The temperature, charge and discharge of each cell is monitored and actively managed by the BMS, a computer built into each battery. In addition to cell monitoring and management, the BMS will prevent over-discharging of cells by disconnecting the load and will prevent cell over-charging by reducing charge current or stopping the charge process. The BMS will also shut down the system if the battery temperature is out of range and wait for it to come down before continuing to charge.

Are lithium batteries good for trolling motors?

Absolutely. They are half the weight with twice the power. Easy to take on and off the boat to charge, or charge them with solar where they are about 20% more efficient at charging than lead acid. They run at a consistent voltage most of the way through their charge cycle which means more efficient motor operation. They have almost four times more amperage per pound meaning less batteries are needed. Ours comes with a bluetooth app so you can check how much charge you have on your phone at any time - lessens the chance of being stranded on the water. Can run as both a starter battery and a trolling motor battery. Can be used to run all your components including power pole, GPS, fish finder, live well, charge your phone.

Can I use a single lithium battery for starting and everything else on my fishing boat?

Yes for sure, we have customers who run their entire boats with a single lithium battery. It is very efficient in terms of weight, space and cost. An excellent solution for skiffs, bass boats, flats boats, jon boats with trolling motors, power poles, live wells, and so on.
