Advanced BMS & Safety Protection
The 72V 20Ah lithium battery pack is safeguarded by the RYD-20S-030 PCM, a multi-layer protection board that continuously monitors every cell string. This lithium ion battery pack features three-tier over-voltage protection (software, AFE hardware and SCOP hardware), over-discharge protection, charge and discharge over-current protection, short-circuit protection, cell-voltage imbalance lockout, and automatic recovery. A temperature-controlled disconnect cuts the output if any cell surface exceeds 70°C. In short, the 72V 20Ah lithium battery protects both itself and your host equipment.
