Trolling motor batteries can get heavy. If you want to keep the weight of your gear to a minimum, your battery is a good place to start.
Choosing a lightweight trolling motor battery is important for kayakers and inflatable boaters looking to cut back on the overall weight of their gear. Pontoon boat owners with more powerful motors that need 24V or 36V batteries will also benefit from lighter batteries.
With AGM batteries, it is power capacity. Light AGM batteries will store less energy, meaning that their Amp Hour (Ah) rating will be lower than that of larger batteries.
With lithium batteries, it is the price. They weigh 3-4 times less than similar AGM batteries, but lithium batteries cost 4-8 times more.
Let’s have a look at a few light AGM and lithium batteries.
