JK SMART ACTIVE BALANCER 16S 2A B2A16S

SMART ACTIVE BALANCER 16S 2A (JK-B2A16S)*

Product Data Sheet

The JKBMS JK-B2A16S Smart Active Balancer is a professional-grade battery equalizer designed for 2S–16S lithium battery packs. Using advanced active energy transfer balancing technology, it transfers energy from higher-voltage cells to lower-voltage cells instead of dissipating energy as heat, resulting in faster balancing, better efficiency, and improved battery lifespan.

With a powerful 0.1A–2A balancing current, this module is ideal for large-capacity battery packs used in solar energy storage, electric vehicles, UPS systems, and DIY lithium projects. Built-in Bluetooth connectivity allows real-time monitoring and configuration through the JK mobile app. Some variants also support RS485 and CAN communication.

Why Choose JKBMS Active Balancer?

Faster Balancing Than Passive BMS

Traditional passive BMS balancing is often only 20mA–150mA, while JK active balancing supports up to 2A, making balancing dramatically faster. Reddit users frequently highlight JK’s active balancing advantage over standard BMS systems.

Better Battery Lifespan

By continuously equalizing cells efficiently, the pack remains balanced for longer, reducing stress on weak cells.

Real-Time Bluetooth Monitoring

Monitor cell voltage, balancing current, and battery condition directly from your smartphone.

Ideal for Large Capacity Packs

Perfect for high-capacity LiFePO4 and EV systems where passive balancing is too slow.
