【Lithium Iron Battery】: The lifespan of LiFePO4 (lithium) batteries is 8 to 10 times longer than that of regular lead-acid batteries (2000~5000 cycles vs 300-500 cycles). The usable capacity also doubles compared to that of a lead-acid battery while the weight is 30% less thanks to its significantly higher energy density.Without any memory effect, the lithium battery can hold a charge better while not in use and will not lose capacity due to the previous discharge state.

【Built-In BMS & Convenience & Maintenance Free】: The built-in BMS (Battery Management System) protects the battery from overcharge, over-discharge, over-current, and short circuits with excellent self-discharge rate. Built-in high temp cut-off prevents charging over 122 °F (50 °C). Plus, Li-Ion batteries can be safer than lead Acid batteries, which have no protection against ground faults.This product is your ideal choice for both outdoor and indoor applications.

【Capacity Expansion】: Our lithium batteries can be connected in parallel and in series for larger capacity and voltage. Max connection in series: Up to four identical batteries for up to 48V.Max connection in parallel: Up to four identical batteries up to 800AH.Batteries can also be connected in parallel and series at the same time for up to 48V 800AH. Only batteries with the exact same voltage and capacity purchased within a six-month window can be used in parallel or series.

【Wide Application】: Our lithium batteries can be used in the following areas: Home energy storage systems, UPS backup, lighting, digital/CCTV cameras, portable TV, e-Robot, electric vehicles, DIY speakers, 12V routers, air pumps, fish finder, golf cart, trolling motor, motorhome/RV & camper, Houseboat, Travel Trailer, Dump Trailer and more.
