product description
Industrial Power for Home Energy Storage
The JK-PB2A16S15P is the definitive choice for installers and DIYers building robust home battery solutions. Engineered for heavy-duty 48V applications, this unit supports constant high-current draw, making it perfect for driving powerful solar inverters and household appliances during peak usage. Because it includes a 2A active balancer, it proactively transfers energy between cells, ensuring that the entire pack maintains maximum usable capacity for the duration of its lifecycle.
Why Choose the JK-PB2A16S15P?
Seamless Inverter Synergy: Equipped with dual-protocol support (CAN and RS485), this BMS acts as a smart interface for your inverter. It automatically shares vital battery health data, optimizing charging profiles for brands like Deye, Victron, Growatt, and more.
Proactive 2A Active Balancing: Unlike passive BMS units, this active system moves energy from high to low cells. This is essential for large-format prismatic cells (100Ah-300Ah), preventing voltage divergence and ensuring you get every last watt-hour out of your battery.
150A Continuous Performance: With a high-current threshold, this BMS is capable of handling significant loads without overheating, providing the reliability required for off-grid living and emergency backups.
Advanced Smart Control: The integrated Bluetooth allows for deep configuration. You can monitor every cell in real-time, adjust protection limits, and perform system maintenance via the JKBMS PC software (using the dedicated adapter) or the mobile app.

Superb craftsmanship, simple and functional.
Instalé el JK-PB2A16S15P en mi banco de 48V de 16 celdas y la comunicación CAN con mi inversor de onda pura funciona de maravilla. Soporta los 150A de descarga continua de forma muy holgada y el balanceador activo de 2A es sumamente potente, corrigiendo cualquier desvío en minutos. La pantalla integrada y la conectividad Bluetooth hacen que monitorear todo el sistema sea facilísimo. Ideal para almacenamiento residencial serio.
The physical hardware is flawless. The 150A rating gives incredible headroom, and the 2A active balancing easily handles any top-end cell drift. My only critique is with the protocol assignment in the Jikong app. When configuring the RS485/CANbus connection for your specific inverter brand (like Pylontech, Growatt, or Victron), the dropdown menus can sometimes be confusing due to minor translation quirks in the app. Make sure you match the correct baud rate and firmware version before connecting the data cable. Once it pairs, the communication is bulletproof, but the initial software handshake takes some patience.
All goods inspected well before shipping.
I recently upgraded to the JK-PB2A16S15P for my 16S LiFePO4 bank, and as a result, the overall system efficiency has increased substantially. Notably, the 2A active balancing is exceptionally powerful, which effectively keeps my cells perfectly synchronized even during high-demand discharge cycles. Furthermore, the 150A continuous capacity handles my inverter’s power surges with ease. Ultimately, this is the definitive, professional-grade solution for a high-performance 16S battery setup.
