JK-B1A8S10P Smart BMS Board (4S-8S, 100A, 1A Active Balancer, CAN/RS485, Bluetooth, Heating + Push Button)

This board is a best-selling solution for creating reliable 12V (4S) and 24V (8S) energy storage systems. It is designed specifically for those building boat batteries (for electric motors and onboard electrical systems), home backup power supplies, RV batteries, or medium-power off-grid solar systems.

With its active balancer and support for communication protocols, this BMS ensures maximum battery safety and extends battery life by 1.5–2 times.

Key features and why you should choose it:

* Ideal for 12V/24V systems (4S-8S): The board works with all popular chemistry types in this range: LiFePO4 (4S-8S), Li-Ion (4S-8S), and LTO (6S-8S). Changing the mode and cell count is as easy as a couple of clicks in the app.
* True 1A active balancer: Most conventional boards use a passive balancer, which simply heats the board and slowly discharges the cells. This one uses a supercapacitor active balancer. It transfers energy from more charged cells to lower ones at up to 1A, operating continuously: during charging, discharging, and even when the battery is idle. * Ultra-low resistance (0.3 mOhm): Thanks to a powerful power board with ultra-low resistance MOSFET switches, the BMS generates virtually no heat at a rated load of 100 A and easily handles short-term peaks of up to 200 A.
* Inverter communication (CAN/RS485): You can connect the battery directly to smart hybrid inverters (Deye, Victron, Must, Growatt, etc.). The inverter will accurately monitor the battery`s condition, temperature, and current capacity, adapting its operating mode accordingly.
* Intelligent winter heating: The BMS controls the heating elements (heating plates). At sub-zero temperatures, the board will first direct the charging current to heat the cells, and once they have warmed up to a safe temperature, it will initiate the main charge.
* Built-in Bluetooth and a convenient button: Manage all settings (voltage thresholds, protection currents, calibration) directly from your smartphone via the JKBMS app. A remote metal button with LED allows you to manually turn the board on and off.
