BMS Battery Management
Li-ion battery management for garden tools and more
RAYS-POWERGarden Tool BMS
Designed for hedge trimmers, lawn mowers and pruners — high-rate discharge, frequent start/stop, outdoor temperature swings. The 12S high-capacity BMS platform adapts to different capacities and cell types by parameter configuration.
- 12S / 20Ah and 50Ah capacity options, high-rate discharge ready
- OV / UV / OC / short / temperature protection
- Multi-stage SOC correction for accurate gauge
- CAN / CAN FD / RS-485 / Ethernet
- Optional Bluetooth / Wi-Fi / 4G modules
- Digital tube display + fault codes
- Ultra-low sleep, auto power off
