PLEASE READ THE DESCRIPTION CAREFULLY.

Shipping to Lower 48 USA states only via Fedex Ground Shipping. No international shipping including Hawaii, Guam, Puerto Rico. Non-USA customers click here.


Easy to use! 12v 100Ah 1200Wh LiFePO4 energy storage in 4s2p configuration using A123 LFP cells. Capable of continuous power output of 100A on the XT connector, 120A wired directly on battery terminals. Safer LFP chemistry, better temperature stability and tolerance compared to regular li-ion 18650 cells. Ultra thin design = small size and ability to accommodate many applications. There is no BMS on these cells > 12v 100A LiFePO4 BMS sold separately here.

NOTE: For any lithium iron phosphate batteries, state of charge cannot be determined by voltage alone, you need to count Amp Hours or Watt Hours. Typical behavior is for the "Resting Voltage" to be 13.2VDC a few hours after your charging session.
