This 12V 4Ah LiFePO4 battery arrives pre-charged and ready to install, with no acid to add and no activation or maintenance needed before your first ride. It's a direct swap for common lead-acid sizes including YTX12-BS, YTZ14S-BS, YTX7A-BS, YTX9-BS, YTZ10S-BS, YTZ12S-BS, and YZ12A-B2, with multiple terminal positions so it installs at nearly any angle without special tools. Rated for 120 cold cranking amps and 240 cranking amps, it delivers about three times the starting power and lifespan of a comparable lead-acid battery, and it's rated for more than 1500 charge cycles. An intelligent BMS protects against overcharge, short circuits, and temperature extremes, and the sealed housing means no acid leaks to worry about. At just 1.98 lbs and 5.91 x 3.43 x 3.66 inches, it's light enough to carry as a spare, and it powers motorcycles, ATVs, snowmobiles, jet skis, scooters, and go-karts alike.
