The Photon has built-in BMS (Battery Management System), which can manage and monitor cells information including voltage, current and temperature. Besides that, BMS can balance cells charging to extend cycle life. BMS has protection functions including over-discharge, over-charge, over-current and high / low temperature; the system can automatically manage the charge state, discharge state, and balance state.

Multiple PTN-BAT-05K-WM-LFP can be connected in parallel to expand capacity and power, and 15 PTN-BAT-05K-WM-LFP can be connected in parallel at most.
