The JKBMS JK-B4A24S Smart Active Balancer is a professional-grade battery equalizer designed for 2S–24S 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–4A 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 4A, 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.
