LFP Battery Charger
LFP Battery Charger – Smart Charging for LiFePO4 Batteries
An LFP (LiFePO4) Battery Charger is a specially designed charger used to safely and efficiently charge Lithium Iron Phosphate batteries. Unlike standard lithium-ion chargers, an LFP charger provides the correct charge voltage (3.65V per cell) and uses a CC-CV charging profile, ensuring long battery life, safety, and optimal performance.
🔋 Why LiFePO4 Needs a Special Charger?
LiFePO4 cells have a different charging voltage curve compared to NMC/NCA Lithium-ion cells.
Using the wrong charger can:
- ❌ Reduce battery life
- ❌ Cause imbalance
- ❌ Damage cells or BMS
A proper LFP charger ensures safe, long-lasting operation.
⚙️ Charging Profile (CC-CV Method)
| Stage | Description |
|---|---|
| CC – Constant Current | Charger supplies steady current until target voltage is reached. |
| CV – Constant Voltage | Voltage remains constant; current gradually reduces. |
| Cut-off | Charging stops when current falls to a safe threshold (typically 0.05C–0.1C). |
🔧 Compatible Battery Voltages
| Configuration | Nominal Voltage | Full Charge Voltage |
|---|---|---|
| 1S LFP | 3.2V | 3.65V |
| 4S LFP | 12.8V | 14.6V |
| 8S LFP | 25.6V | 29.2V |
| 12S LFP | 38.4V | 43.8V |
| 16S LFP | 51.2V | 58.4V |
| 24S LFP | 76.8V | 87.6V |
