Fast mains charging for 4S LiFePO4 batteries
The 110–220 V AC mains-powered desktop charger is designed to charge 4-series (4S), nominal 12V LiFePO4 battery packs with a fixed 14.6 V final charging voltage and up to 20 A charging current.
Thanks to its CC/CV charging profile optimized for LiFePO4 chemistry, it can be suitable for fast and stable charging in boats, camper vans, workshops, or off-grid systems, provided that the battery and connection match these charging parameters.
What is it for?
For mains charging of 12V, 4S LiFePO4 batteries when the source is not vehicle-side DC power, but direct AC mains power.
Why is it useful?
The 20 A charging current can allow faster charging, while the 14.6 V final voltage matches a 4S LiFePO4 system.
What system is it for?
For 12V LiFePO4 energy systems where the battery chemistry, nominal voltage, and charging connection are compatible with this charger.

Main advantages
- It operates from mains power, making it convenient to use in a workshop, at a base location, or near a permanent AC source.
- The fixed 14.6 V final charging voltage matches 4S LiFePO4 systems.
- The 20 A charging current can allow faster recharge for a suitable battery.
- The CC/CV charging characteristic is tailored to LiFePO4 chemistry.
Use and connection
- Use it only with a battery whose nominal system voltage and chemistry match the charger parameters.
- The charger connection must always be matched to the specific PowerBox configuration.
- Before first use, it is advisable to check connector polarity and cable compatibility.
- With a higher-capacity battery, 20 A charging can be beneficial, but the specific BMS and battery manufacturer recommendations should also be taken into account.
Warning
- It may only be used with LiFePO4 batteries, not with other battery chemistries.
- It is not intended for 24V or 36V LiFePO4 systems.
- Incorrect charger connection or reversed polarity may damage the system.
- Actual suitability must always be verified based on the specific battery, BMS, and connection.
