BMS board - JK-B1A8S10P 100A, 1A balancer

BMS The JK-B1A8S10P controller is designed to work with 4–8 battery cells. The maximum charge and discharge current is 100 A, and in peak loads it reaches 200 A. Thanks to the balancing current of 1 A, the device ensures uniform energy distribution between all cells.

Key features:

• Convenient connection via Bluetooth using a mobile application.
• Built-in protection against short circuit, overcharge, deep discharge and overcurrent.
• Support for 4-8 cells for lithium batteries of various types.
• Active balancing system for optimal energy redistribution between cells.
• Ability to connect an external information display.
• Six built-in levels of battery protection

Short circuit protection

• Overvoltage (overcharge) protection – with the ability to manually adjust the voltage limit
• Deep discharge (overdischarge) protection – also with threshold voltage adjustment
• Current protection – setting of operation when the permissible current is exceeded
• Temperature protection – monitoring of overheating and low temperatures with the function of controlling the heating element
• Balancing connection control – detection of open circuit or incorrect connection

Assembling and Configuring Jikong
