Wide compatibility for 4S5S battery packs Works with LiFePO4, ternary polymer, and lithium titanate cells. Supports 1.8V–4.2V per cell and pack capacities from 60Ah to 300Ah, enabling versatile use across different systems. Capacitorbased energy transfer technology Balances cells using flying capacitor energy transfer without the need for an external power source. Leverages the pack's own energy for efficiency balancing with minimal heat generation. accuracy balancing current Uses ultralow resistance MOSFETs and a 2 oz copper PCB to deliver a dynamic balancing current of 0–5.5A with voltage accuracy of ≤5 mV. This ensures fast, precise equalization and uniform cell voltages. Intelligent sleep protection Automatically enters hibernation when the pack voltage falls below 2.7V. Reduces standby power to less than 0.1 mA, helping prevent overdischarge damage and extending pack life. Use scenarios Home energy storage and solar backup: balance 4S5S LiFePO4, ternary, or LTO packs in 60–300Ah banks to improve longevity and reliable performance for offgrid or backup power systems. Industrial and commercial energy storage or UPS: maintain safe, balanced largecapacity packs in 4S5S configurations for consistent, longterm operation. Electric mobility and capacity tools: support balanced operation of large 4S5S packs in power tools, fleet charging, or other equipment requiring dependable cell balancing.
