25A 53.2V Charger for Lithium LiFePo4 15S Pylontech Battery

25A 53.2V Intelligent Charger for Pylontech Batteries

✅ Compatible with: Pylontech US2000, US3000, US5000
✅ 12-Month Warranty
✅ Revives Batteries in Low State of Charge (SOC) Alarm

Essential for System Maintenance

Struggling with a red Alarm LED and a shut-off inverter? This charger is designed to revive Pylontech batteries that have dropped below their minimum SOC, ensuring reliability in winter months. Regular use helps maintain a healthy battery and prevents deep discharge issues.

Key Features:

✅ Optimized Charging for Pylontech Batteries – Supports 15-series LiFePO₄ cells, delivering 53.2V at 25A, aligned with Pylontech's recommended charge profile.
✅ Advanced Protection System – Includes reverse polarity, short circuit, overvoltage, overcurrent, thermal, and low-voltage protection for maximum safety.
✅ Pre-Charge Recovery Mode – Revives deeply discharged batteries and reactivates the Battery Management System (BMS).
✅ High Efficiency & Low Standby Power – Achieves 90% efficiency at 220V input with minimal power loss.
✅ Durable & Weatherproof Design – IP66-rated aluminium casing ensures dustproof and waterproof protection.
✅ Built-in Charging Logic – Features constant current (CC) and constant voltage (CV) modes, with automatic cut-off when fully charged.

Technical Specifications:

• Input Voltage: 90-260V AC (47-63Hz)
• Max Output Power: 1250W
• Output Voltage: 53.2V 
• Output Current: 25A
• Protection Rating: IP66
• Operating Temperature: -20°C to +65°C
• Weight: 3.2kg

Intelligent Charging Process:

1. Pre-Charge Mode – Safely activates a deeply discharged battery.
2. Constant Current (CC) Stage – Charges at a steady 25A until reaching the optimal voltage.
3. Constant Voltage (CV) Stage – Maintains 53.2V, allowing charge current to gradually taper off.
4. Auto Cut-Off – Stops charging when fully charged to prevent overcharging and extend battery life.
