B-Grade battery. 12v 50Ah 600Wh LiFePO4 energy storage in 4s configuration using A123 LFP cells. Capable of continuous power output of 50A from the battery terminals. The reason these are B-Grade is because they are made up of cells that are not matched. Safer LFP chemistry, better temperature stability and tolerance compared to regular li-ion 18650 cells.

There is no BMS on these cells > LiFePO4 BMSs sold separately here. See BMS PCB video 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.
