product description
Professional Home Energy Management with the PB2A16S10P The JK-PB2A16S10P is designed to be the central nervous system of your residential battery bank. Unlike standard BMS units, this ESS-specific model is built to handle the rigorous demands of daily solar cycling. Because it features a powerful 2A active balancer, it can quickly correct voltage imbalances in high-capacity 100Ah, 200Ah, or 280Ah cells. This proactive energy transfer ensures that no single cell limits the capacity of your entire 48V bank, significantly extending the service life of your lithium investment.
Why Choose the JK-PB2A16S10P for Your Powerwall?
Seamless Inverter Integration: Equipped with dual CAN and RS485 communication ports, this BMS supports the protocols of most global inverter brands. It shares real-time battery data with your solar system to optimize charging curves and system safety.
Superior 2A Active Balancing: Large-format energy storage cells require high-current balancing. The 2A active current is up to 20 times more powerful than traditional passive balancing, keeping your pack perfectly top-balanced for maximum solar harvest.
Comprehensive 100A Performance: With a 100A continuous rating, this BMS supports up to a 5kW load. It is the ideal fit for standard household power demands and off-grid setups.
Smart App & Monitoring: Use the JIKONG App via Bluetooth to view individual cell voltages, cycles, and temperature in real-time. You can adjust protection thresholds specifically for Li-ion, LiFePO4, or LTO chemistries.
Industrial-Grade Safety: Featuring high-precision voltage and current acquisition, the BMS protects against overcharge, over-discharge, over-current, and extreme temperatures, providing peace of mind for home installations.

Sehr gut! Perfect board for my 48V server rack battery storage. The RS485 communication linked up with my inverter straight away, and the 2A active balancing keeps all 16 cells within a few millivolts of each other. Having the optional LCD display port makes reading pack status completely effortless without always opening the app. Highly reliable kit.
Reasonable price while keeping good quality.
Swapped out my old Daly board for this JK-PB model. The RS485 communication set up with my system on the first try. It runs cool even when pulling a steady 80A, and the 2A balance current means I don’t have to worry about top-balancing manually anymore. Excellent product.
Great workmanship, reliable.
This is the lowest-priced model in the PB series, yet it is perfectly suited for implementing battery parallel connections and communicating with the inverter; while it costs only slightly more than the B2A series, it looks much more premium.
