Overview
DALY High-Current BMS is a smart battery management system (BMS) designed for lithium battery packs, supporting Li-ion and LiFePO4 (also listed: LTO). It is offered in continuous current options of 600–800A and supports 8–24S configurations (selection varies by option). Smart communication is supported via APP/PC/IoT, with communication lines listed as UART/RS485/CAN. An optional brake resistor interface is shown for surge current handling during braking.
