Balancing current and control - Balancing current 0–5.5 A; the current available increases as the pack becomes more balanced. Includes a manual standby switch for easy power control; standby current is present when idle. Precision and efficiency - Active mode draws less than 0.1 mA and balancing voltage accuracy is better than 5 mV, ensuring precise cell balancing with minimal parasitic draw. Hardware and construction - New MOSFET with very low on-resistance combined with a thick 2 oz copper PCB for improved efficiency and durability. Start-up and operation - The capacitor works with the transfer charge slider; the balance board is connected to the battery and balancing begins automatically. Key benefits - Improves pack balance quickly and reliably, extending overall battery life and performance. - Reduces risk from imbalanced cells, enabling safer operation and more predictable pack behavior. - Low idle current and high-precision balancing voltage support long-term, stable performance. Use scenarios - After charging a multi-cell battery pack for RC vehicles or tools, to bring all cells to a uniform voltage before use. - On-site field maintenance of battery packs for drones or power tools; connect and start balancing without removing components. - In production testing or assembly, integrate with packs to verify balance and initiate balancing automatically as part of quality checks.
