8S 1.2A Active Inductive Battery Equalizer Balancer PCB Lithium
8S 1.2A Active Inductive Battery Equalizer Balancer PCB Lithium
8S 1.2A Active Inductive Battery Equalizer — High-Efficiency Lithium Cell Balancer
Keep your 8-cell lithium battery pack performing at its best with this 8S 1.2A Active Inductive Battery Equalizer. Using advanced inductive energy-transfer technology, this PCB balancer continuously monitors and redistributes charge between adjacent cells — extending overall pack lifespan, maintaining consistent cell voltages, and reducing long-term battery maintenance costs. Made in Mainland China.
Key Features
- High-Efficiency Inductive Balancing: Transfers energy inductively between adjacent cells rather than dissipating it as heat, delivering up to 1.2A equalization current for fast, efficient balancing.
- Smart Trigger Thresholds: Automatically activates when the voltage difference between adjacent cells exceeds 0.1V (delivering ~0.5–0.7A); ramps up to the full 1.2A when the difference exceeds 0.2V; stops when the difference drops below 0.03V — no manual intervention needed.
- Ultra-Low Standby Consumption: Static power draw does not exceed 20 microamperes when in sleep mode, ensuring negligible drain on your pack during storage or idle periods.
- Wide Working Voltage Range: Compatible with ternary and iron-phosphate lithium cells in the 2.0V–4.5V per-cell range. Note: Not compatible with LTO (Lithium Titanate) batteries.

Built-In Status Indicator LED:
- LED ON — equalization is actively running
- LED OFF — circuit is in sleep mode
- LED FLASHING — a weak/drop cell or circuit fault has been detected
- Pure Copper Wiring: Comes with a 22AWG pure copper harness (30 cm / 11.81 in) for reliable, low-resistance connections.
- Must Be Used with a BMS: Due to the adjacent-cell equalization principle, this board must be connected alongside a lithium battery protection circuit (BMS) — it is not a standalone maintenance or diagnostic tool.

Frequently Asked Questions
Q: What battery types is this 8S 1.2A active equalizer compatible with?
A: This inductive battery balancer is compatible with ternary lithium and iron-phosphate (LiFePO4) lithium cells operating between 2.0V and 4.5V per cell. It is not compatible with LTO (Lithium Titanate) batteries due to their different voltage characteristics.
Q: Does this balancer work as a standalone Battery Management System (BMS)?
A: No. Because it uses an adjacent-cell equalization method, this PCB board must always be used together with a separate lithium battery protection circuit (BMS). It handles voltage equalization only and does not provide overcharge, overdischarge, or short-circuit protection on its own.
Q: What does the flashing LED indicator mean on the battery equalizer?
A: A flashing LED signals that one or more cells may be weak or have dropped significantly in voltage, or that there is a circuit fault. A steady-on LED means equalization is actively running, while a completely off LED means the circuit is in low-power sleep mode (voltage differences are within the 0.03V threshold).
Q: What is the maximum equalization current this board can deliver?
A: The board delivers approximately 0.5–0.7A when the voltage difference between adjacent cells is above 0.1V, and scales up to a maximum of 1.2A when the voltage difference exceeds 0.2V. The equalization current automatically scales down as the cells approach balance.
