Next, B- P- is conductive, voltage from P- is the same from B-, and the BMS will work well - ★【Bluetooth Module】It can be connected to Android or IOS app, so you can check the battery condition in real time with your phone. You can set battery capacity, protection temperature, protection voltage, etc. via Bluetooth module - ★【Bluetooth BMS Starting Method】Method 1: Press the button on the Bluetooth module to activate bms directly. Method 2: When charging or charging, the B line must be connected to the entire negative pole of the battery pack. If Method 1 fails to activate BMS, try Method 2 to activate BMS - ★【VNSZNR BMS】BMS is made with high quality Mos and IC. Longer battery life. Extremely low power consumption. The entire device consumes less than 50uA. PCB uses ESD conformal coating with high corrosion resistance, high water resistance, and high impedance. Waterproof, dustproof and shockproof - ★【What You Get】1 x VNSZNR Bluetooth BMS Lifepo4 4S 12V 200A, 1 x Bluetooth Module, 1 x Balance Cable, 1 x English Manual, the package also includes B-P-cable, NTC cable (temperature sensor). 36 month warranty and friendly customer service.
