Active Balancer Series

Battery cells drift apart over time. When one cell goes out of range, the BMS shuts down the entire pack — even if the rest are fine. The JKBMS Active Balancer prevents this by continuously transferring energy between cells in real time, keeping every cell in balance and the pack running safely.

Unlike passive balancing which burns excess energy as heat, JKBMS uses ultracapacitor energy transfer — low heat, low loss, real-time, and effective at any voltage delta.

  • Minimizes cell voltage difference — prevents BMS over/under-voltage cutoffs
  • Extends battery lifespan and improves safety
  • Real-time balancing during charge, discharge, and at rest
  • High-current 5A & 15A models also suitable for large-capacity battery pack recovery
  • Supports LiFePO4, Li-ion, LiPo, LTO, lead-acid | Bluetooth app on all models
