3-4S 1.2A Lipo Balancing board
The 3–4S 1.2A LiPo Balancing Board is a compact and efficient battery management solution designed to ensure balanced charging and discharging of 3-cell and 4-cell LiPo battery packs. By maintaining equal voltage across each cell, it extends battery life, improves performance, and enhances safety, perfect for high-demand embedded and RC applications.
It works on the principle of adjacent equalization and cannot be used for maintenance as a stand-alone. It must be used with the lithium battery protection board. The pressure difference generated by charging and discharging triggers the board to achieve energy transfer and balance.
Key Features
- Supports 3S to 4S LiPo Packs: Compatible with 3S and 4S batteries.
- 2A Balancing Current: Actively balances cells during charging/discharging. When adjacent voltage difference is < 0.1V current is 0.5 – 0.7A. If it’s > 0.2V, current is 1.2A.
- Plug-and-Play Design: Easy to connect to the battery’s balance lead.
- Compact and Lightweight: Suitable for integration in drones, RC vehicles, or embedded power systems.
- Improved Battery Health: Prevents overcharging or undercharging of individual cells.
- Operating Voltage: 2.0V - 4.5V (per cell)
- Balancing Current: 0.5 – 0.7A and 1.2A
