Our take on the 100Ah Lithium Battery (LiFePO4) 12.8V

This is a 12.8V 100Ah lithium iron phosphate (LiFePO4) battery built for boat electronics, trolling motors and portable power. It weighs about 26.65 lb, roughly half the weight of a comparable lead-acid battery, and fits a group size 27 case while offering more capacity than many group 31 batteries. Bluetooth monitoring through the Amped Outdoors app and active heating for charging below freezing set it apart from plain LiFePO4 rivals. It suits anglers and off-grid users who want lighter, longer-running power and can pair it with a compatible 10A-or-higher charger.

About the 100Ah Lithium Battery (LiFePO4) 12.8V

This is a 12.8V, 100Ah lithium iron phosphate (LiFePO4) battery for boat electronics, trolling motors and portable outdoor power. It weighs 26.65 lb. Its capacity is similar to SLA batteries twice its size at half the weight. It is a group size 27 battery with higher capacity than many group size 31 batteries.

Built-in Bluetooth lets you monitor one or several batteries at once. Use the Amped Outdoors App only. Other apps may connect but can cause wrongful updates, and a battery that stops working because of them is not covered under warranty. Up to 4 batteries can be wired in series for higher voltage.

The battery has an active heating function for charging below freezing. A compatible charger heats the battery when it is below freezing and starts charging once it reaches 32°F. Heating continues until the battery reaches about 50°F, then it accepts the full charge rate. The battery is sold without a charger.
