CNL-EP027-C04S9090TY series PCM/BMS/PCB to respectively used to normal use and CAR START.
Size: 100 * 60 * 8 mm
BMS attachment contains voltage gathering line (balancing line).

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.

BMS used Japan S8209 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 50mA.

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.
