*NOTE:The type and number of strings of the BMS must be consistent with the battery pack;

If you need BMS to communicate with the inverter, please let us know before placing the order.

Multiple and comprehensive protections


Supports parallel connection of various battery pack and safe expansion Integrated parallel module to avoid large current impacts when battery packs are connected in parallel.	Making load easy yo start High-power pre-charging can effectively avoid false triggering of protection caused by high current at startup moment and unsuccessful power-ups.	100mA passive balancing helps extend lithium battery life Compared with conventional BMS(with 30mA passive balancing),the balancing efficiency is increased by more than 3 times.	Battey pack temperature protection,prevent safety hazards Advance temperature warning and timely power cut-off can effectively prevent battery fires and other hidden dangers.

Professional response to high currents
