Overview
Second-life batteries reconfigure retired power cells, after testing and sorting, into 48 V/51.2 V modules or rack systems for telecom backup, C&I storage, low-speed vehicles and residential storage. SOH, internal resistance, cycle and safety test data are provided.
- 48 V / 51.2 V standard modules
- SOH ≥ 70%
- RS485 / CAN communication
