The Renogy Mini Size 12V 20Ah Trolling Motor Lithium Iron Phosphate Battery is a small LiFePO4 battery that can take the place of a 20Ah lead-acid battery while weighing about half as much. It is well suited to kayaks and small boats running fish finders or trolling motors, and it also works for scooters, ham radio operators heading out on POTA activations, and other portable 12V gear.

Compared with lead-acid, it runs devices around 30% longer per charge and lasts roughly eight times as long over its life, with a rating of 4,000 cycles at 80% depth of discharge. Its IP65 housing resists water, dust, and corrosion, which matters around splashing water and in rough outdoor conditions.

A built-in battery management system provides more than 20 protections, including a low-temperature charging cut-off. The battery has no Bluetooth of its own, but it can be paired with a Renogy 300A Battery Shunt (sold separately) to track it through the app.
