What You Need to Know About RELiON Trolling Motor Batteries

Posted July 24, 2020

Battery selection is essential when it comes to your boat. When deciding on your next trolling motor battery, it could mean the difference between the battery failing and having a great fishing trip with no interruptions. A bass boat needs reliable marine batteries as they are necessary for both starting and running your fishing machine. Not all batteries serve the same purpose as some are intended specifically for producing cranking power for engine startups and others are used exclusively for running your trolling motor. Curious about trolling motor batteries and want to learn more? We’ve put together the top seven most frequently asked questions around lithium batteries for trolling motors.

1. How many RELiON lithium trolling motor batteries do I need?

It depends on your trolling motor voltage. RELiON offers 12-Volt and 24-Volt lithium batteries. If you have a 12-Volt trolling motor, then you can choose from several 12-Volt options. If you have a 24-Volt motor, you can use 2 12-Volt batteries in series or a single 24-Volt battery and if you have a 36-Volt motor you can use 3 12-Volt batteries in series.


2. Which RELiON 12-Volt battery should I use for my trolling motor?

RELiON offers several 12-Volt battery options to choose from. The most common models are; RB50, RB75, RB80 and RB100, which are 50Ah, 75Ah, 80Ah and 100Ah, respectively. To get the same runtime as a wet or AGM lead-acid battery, use a lithium battery that is 60% the capacity of that lead-acid battery. If you want more time on the water, size up from there.

Example: 60Ah RELiON lithium battery = 100Ah lead-acid battery

3. Are RELiON lithium batteries a drop-in replacement to my lead-acid battery?

RELiON offers the standard size batteries; Group 24, Group 27 and Group 31.

4. Do I need to use a lithium starter battery if my trolling motor batteries are lithium?

No, you can use a lead-acid starter battery with your lithium trolling motor batteries.

RB100-HP

5. Does RELiON offer a lithium starter battery?

RELiON has a RB100-HP, which is a Group 31 dual-purpose battery that can be used for starting.

6. What type of charger should I use for my RELiON lithium batteries?

We recommend you use a multi-bank charger so that each 12-Volt battery can be charged separately to ensure they stay balanced and get fully charged. Ideally, use a charger with a lithium charge profile, however, most AGM charge profiles will work just fine.

7. Do I need to charge my batteries each time I use them?

Unlike lead-acid batteries, lithium batteries do not get damaged if they sit partially discharged for extended periods of time. However, we do recommend you charge them after each use to ensure you have the maximum runtime available, every time you use your boat.
