Five steps, on every pack
Every pack comes with its own test report. We can retrieve the report of a battery installed two years ago.
- 01
Sourcing
Grade A LiFePO4 cells bought direct, in homogeneous batches.
- 02
Sorting and matching
Open-circuit voltage and internal resistance measured on every cell.
- 03
Assembly
Mechanical and electrical assembly, controlled torque, insulation checked.
- 04
Calibration
Balancing and a full charge-discharge cycle on an instrumented test bench.
- 05
Final check
Actual capacity measured, test report archived under the serial number.
Compatible with the inverters you already install
Communicating BMS over CAN and RS‑485 on all 25.6 V and 51.2 V models, with preconfigured protocols. Voltage, current, temperature and state of charge are reported to the inverter in real time. Commissioning takes minutes.
Inverter not listed? We bench-test it in our workshop and send you the procedure before you order.
