Over the past few years, we've accumulated a substantial number of LiFePO4 blades from customer returns, open boxes, repair left over and even scam recovery. All the blades have been individually tested and placed on the shelf for maintenance purposes.
These battery blades are not in new condition but in good shape without any puff cell, cell IR (internal resistance) ranging from 2.0 ~ 3.0 milli-ohm, it translate to 100+ Amp for 10 seconds, more than enough to power go-kart and your power tool. Each blade is in 2P5S configuration and would be perfect in 15S configuration for 48v solar storage systems or perhaps 16v car audio systems.
Note: no BMS included, DO NOT put these blades into a Prius, it will not last.
Note: no warranty will be provided for these blade.
-------------- blade specification below --------------
