4S Active Battery Balancer 5A for NCM and LiFePO4 with Voltage Display
The 4S Active Balancer (model DS0855) is an electrical device designed to maintain balanced voltage across ternary lithium (NCM) and lithium iron phosphate (LFP) battery cells. By performing full-disk equalization with a maximum balancing current of 5A, it optimizes energy conversion and helps prolong the efficiency of your battery pack.
Key features
- Active Balancing Technology – Optimizes energy across all battery strings simultaneously for consistent performance.
- High Precision – Achieves voltage balance accuracy up to 5mV with a minimum difference of 0.01V.
- Low-Voltage Protection – Automatically enters sleep mode when battery voltage falls below 2.7V to prevent over-discharge.
- Real-Time Monitoring – Includes a display screen showing total and individual battery string voltages with ±5mV accuracy.
- High-Current Capacity – Handles a maximum balance current of 5A when the voltage difference is approximately 1V.

FAQ
Does this fit my battery type?
This balancer is designed for ternary lithium (NCM) and lithium iron phosphate (LFP) batteries.
How does it protect my battery?
It features an automatic low-voltage sleep mode that stops operation if the voltage drops below 2.7V to prevent over-discharge.
Does it require an external power supply?
No, the unit is powered directly by the internal energy of the connected battery pack.
