SPECS
FAQ
No. This charger is specifically designed for 12.8V (4S) LiFePO₄ batteries. Using it with other chemistries may cause damage or safety risks.
Yes. The charger uses a CC/CV charging algorithm and will automatically stop or maintain the charge as required. However, always follow your battery manufacturer’s manual for best practices.
Green flashing – Standby / Connected to power
Green solid – Charging / Fully charged
Red flashing codes – Error (input failure, overheat, overcurrent, overvoltage, or short circuit)
Yes. With an IP66-rated aluminum casting housing, the charger is protected against dust and splashing water. However, avoid direct rain immersion and ensure adequate ventilation during use.
When the battery is fully charged, the green LED stays solid. The charger will either stop output or maintain a safe trickle depending on the battery/BMS condition.
