Lithium Iron Phosphate Battery Balancer Brief overview This balancer maintains charge and discharge balance in seriesconnected battery packs of up to five cells (maximum pack voltage 60V). It provides automatic voltage equalization by transferring current from highervoltage cells to lowervoltage cells, helping preserve longterm pack health without requiring ongoing maintenance. Key benefits Prevents cell imbalance and premature pack failure by actively equalizing voltages during charging, discharging, and idle periods. Works without changing the original charging system, so it can be added to existing setups with minimal adjustments. Low standby current conserves energy when the pack is not active. Simple, safe installation using clear red and black wiring and M8 terminals. Main features Automatic bidirectional equalization: activates when a cell voltage difference exceeds 10 mV and transfers current from highervoltage cells to lowervoltage cells. Compensation current: adjustable 0 to 10 A to handle imbalance during normal operation. Low standby consumption: ultralow 8 mA at 12 V when not actively balancing. Cell compatibility: supports 2.4 V to 12 V cell types, including lithium iron phosphate, leadacid, and nickelmetal hydride chemistry. Configurations: suitable for series and parallel battery arrangements; designed for fivecell series stacks (up to 60 V total). Installation: 80 cm wiring length with M8 terminals for reliable mechanical connection; unused terminals may remain open safely. Safety protections: reverse polarity protection, insulation safeguards to reduce short circuit risk, and a lock voltage of 1.8 V to protect deeply discharged cells. Models compatibility: compatible with HA03 and HC03 type systems. Physical: black ABS housing, dimensions 62 x 153 x 27 mm, with red and black wiring for easy polarity identification. Practical applications Solar energy storage: keep a 5cell LiFePO4 battery bank balanced in offgrid or hybrid solar systems to maintain usable capacity and extend service life. Electric vehicle or mobility platforms: stabilize series cell stacks in small electric vehicles, scooters, or batterypowered equipment that use 2.4 V to 12 V cells. Backup power systems: maintain readiness and health of multicell backup battery banks used with inverters and UPS units. Installation and operation notes Install in series across five cells; ensure correct polarity using the red and black wires and M8 terminals. Device will operate automatically whenever cell voltage difference exceeds 10 mV; no user intervention is required during normal cycling or idle periods. The balancer will not interfere with original charging system functions and is safe to use with unused terminals left open. Observe reverse polarity protection and insulation instructions during connection to reduce risk of short circuits. What makes this unit stand out Precise, lowthreshold activation at 10 mV for early imbalance correction. Wide compatibility with common 2.4 V to 12 V cell types and support for series or parallel installations. Robust safety features and practical installation hardware in a compact ABS housing.
