Best 12V and 24V Lithium Trolling Motor Batteries
Lithium electric trolling motor batteries offer many advantages over lead-acid batteries, including lightweight design, a large number of charging/discharging cycles, a very low self-discharge rate, more constant output voltage, almost no capacity loss with the current increase, etc.
Also, lithium trolling batteries still have some issues, like high initial price and safety concerns. For safety reasons, lithium trolling motor batteries are almost exclusively Lithium Iron Phosphate (LiFePO4) batteries featuring built-in Battery Management Systems (BMS), protecting the battery from unwanted events like short circuit, overcharge, over-discharge, and similar.
