Neexgent Smart Bms 7s Li-ion 8s 20s 16s 13s Lifepo4 200a 300a 72v 60v 48v 36v 24v Bms For Lithium Ion Battery Pack

Specially designed for 7 ~ 20 series battery packs of power batteries, electric bicycles, motorcycles and other
products; it can be applied to lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium
iron phosphate, etc. The protection board has strong load carrying capacity and the maximum continuous discharge current can reach
200A.
● 7-20 cell series protection, and automatically recognize the number of battery strings ● The car gauge level simulates the front
chip, the voltage acquisition precision is high;more secure and reliable. 
● Various protection functions for charging and
discharging 
● Power switch for relay, high voltage, more reliable. 
● Accurate SOC calculation with automatic SOC learning function
● Bluetooth communication 
● Optional RS485 communication function can read all battery data in real time and upgrade online. 
●Optional CAN communication function 
● Reserve switch control protection panel output.There is a discharge switch to have a pre-charge function to prevent lighting 
● When the standing time reaches the set value (page switching time for parameter setting), the machine will automatically shut
down and sleep to reduce standby power consumption. 
● Support series connection, but the total number of series after series connection is less than or equal to 32 series
● Parallel use of battery packs is not supported (battery packs are directly connected in parallel, and there is a problem of
large current discharge of high-voltage battery packs to low-voltage battery packs)
