INQUIRY

GPB - 4E series PCM/BMS/PCB to provide two versions, respectively used to normal use and CAR START.

Size: 100 * 70 * 10 mm

BMS attachment contains voltage gathering line (balancing line).

The difference between two type of BMS:

1: When cars and motorcycle startup, will requires a large current up-to 200-500A. , so for the auto start BMS didn't have overcurrent protection and short circuit protection.

2:A version filled with over-current short and circuit protection at 80Amp. suitable for inverter, such as energy storage purposes.

The main difference is that the car start BMS did not have overcurrent and short circuit protection, if not used in car started, please select a normal use BMS, to ensure batteries works well.

BMS used Japan MM3474 series IC , Well-known MOSFET, so BMS has better performance

We use aluminum heat sink, Conductive copper,Reasonable design in order to the decrease of the resistance.

Balance current 100mA.

Note:
Welding balancing wire-line please disconnect with the connection of the BMS,

1:Correctly distinguished Positive and negative, Incorrect will damage BMS

2:Conductive articles is prohibit contact with BMS

3:Electrostatic will cause damage to electronic components

4:Insulation treatment is necessary.
