2S 10A 8.4V Li-ion Battery Protection Board with Balance

The 2S 10A 8.4V Li-ion Battery Protection Board with Balance is a high-performance Battery Management System (BMS) designed to monitor, protect, and balance 2-series Lithium-Ion (7.4V/8.4V) or Lithium Iron Phosphate (6.4V) battery packs. Equipped with high-accuracy voltage detection and delay circuits, this compact module ensures your custom battery packs operate safely under various load conditions. It effectively prevents battery degradation by guarding against overcharging, over-discharging, and overcurrent faults.

This BMS features an integrated cell-balancing (equalization) circuit utilizing onboard power resistors to bleed off excess charge from higher-voltage cells. This ensures all cells in your pack reach their maximum capacity uniformly, significantly extending the overall cycle life of your battery pack. It is highly compatible with standard 18650 and 21700 cells, making it an essential component for DIY power banks, robotics, RC vehicles, solar-powered systems, and portable electronics projects.

Features:

• Dual-Cell Balancing: Onboard equalization circuitry balances cell voltages during charging to maximize pack capacity and lifespan.
• Robust Protection: Provides reliable protection against overcharge, over-discharge, overcurrent, and short-circuit conditions.
• High Current Delivery: Supports a continuous discharge current of up to 10A, suitable for medium-power motor and DIY projects.
• Compact Form Factor: Ultra-thin and lightweight design allows easy integration into tight battery enclosures.
• Low Quiescent Current: Consumes minimal standby power, preventing battery drain during long storage periods.
• Clear Solder Pads: Clearly labeled B+, B-, BM, P+, and P- pads ensure straightforward wiring and assembly.
