BAT-C-18650-AE-6S 6S 6A Active Hybrid Battery Balancer for 18650 Lithium Battery Packs

6A Active Hybrid 4S Balancer for 18650 Lithium Battery Packs – Supports Li-ion, LiFePO4, and LTO

It ensures real-time voltage equalization between cells using a capacitor-based energy transfer method, maintaining battery health, extending cycle life, and improving pack performance.

The module supports up to 6A balancing current, with precision equalization accuracy of 0.005–0.01V and extremely low operating power consumption (1.5–2.5mA). It enters ultra-low-power sleep mode when cell voltage drops below 2.5V, preventing over-discharge.

Features:

• Supports multiple chemistries: Lithium-ion (NMC), LiFePO4, Lithium Titanate
• Active hybrid equalization: Energy is transferred via capacitors between adjacent cells, then balanced using high-frequency parallel connection
• High current balancing: Up to 6A balancing current depending on voltage difference
• Equalization accuracy: Maintains balance within 0.005V–0.01V
• Ultra-low power design:
  • Operating current: 1.5–2.5mA
  • Sleep mode triggers below 2.5V per cell with <1µA power consumption
• Automatic or manual shutdown to protect deeply discharged batteries
• Expandable: Modules can be cascaded for more series cells (e.g., combine with 6S or 17S units)
• Running indicator LED: On = active; Off = under-voltage sleep or manual shutdown
