IV. Product Advantages
Precision Active Balancing for Extended Battery Life
Uses real-time energy transfer to balance cells, resulting in an inter-cell voltage difference of ≤ 3mV after balancing. This eliminates uneven cell wear and ensures long-lasting battery health.Ultra-Wide Compatibility
Works with 4S-24S battery packs and supports expansion to 28S, 32S, 36S, and beyond via cascading. It is compatible with multiple battery types (Li-ion, LiFePO4, LTO) and even super capacitors, making it a versatile tool for various energy storage systems.Accurate Monitoring and Flexible Adjustment
Measures single-cell voltages from 1V to 5V with ±3mV accuracy, providing reliable data for battery status tracking.
Allows independent adjustment of balance current (0.1A to 1A/2A/5A/10A) to match specific battery needs, regardless of cell voltage differences.
Convenient Bluetooth Control
Connects via the JIKONG BMS app (iOS) or JK BMS app (Android), enabling real-time monitoring of cell status, balance progress, and setting adjustments directly from a phone. This user-friendly interface simplifies operation for all users.Smart Protection for Safe Operation
Features equilibrium line resistance detection to identify contact issues early, preventing potential failures. Additionally, robust self-protection ensures the equalizer won’t burn out even in unexpected scenarios, enhancing overall safety and durability.
