⚡ HIGH-CURRENT PERFORMANCE

The stated 380A continuous discharge capability provides substantial current availability for high-demand caravan and motorhome electrical systems.

This makes the battery suitable for appropriately engineered high-power inverter installations, but inverter selection must still account for actual DC current demand, surge requirements, battery state of charge, cable sizing, fuse protection, connection quality and BMS limits.

---

🔌 CHARGING REQUIREMENTS

The supplied specifications recommend a charge current of up to 130A.

• Bulk / Charge Voltage: 14.2–14.6V
• Absorption / Float Voltage: 13.4–13.6V

Compatible lower-output charging systems can also be used, although recharge times will increase substantially with a 620Ah battery.

Your DC-DC charger, solar charge controller and 240V charger should all be configured to suit the required LiFePO4 charging profile.

❓ QUICK FAQ

Can I replace an AGM battery bank with this 620Ah lithium battery?

Potentially, but the complete charging system must be lithium compatible. Check your DC-DC charger, solar charge controller, 240V charger and other connected equipment before changing from AGM to LiFePO4.

What charging profile does it require?

The supplied specifications call for a 14.2–14.6V charge voltage and 13.4–13.6V absorption/float voltage.

What charge current is recommended?

The stated recommended charge current is 130A. Lower-output compatible charging systems can also be used, but a 620Ah battery will take considerably longer to recharge.

Can it run air conditioning, induction cooking or a washing machine?

It can be used as part of an appropriately engineered inverter system supplying high-demand appliances. Actual suitability and runtime depend on appliance wattage, inverter efficiency, surge demand and the complete electrical system.

Can the 620Ah battery run a large inverter?

The stated 380A continuous discharge capability provides substantial current availability. Suitable inverter size still depends on actual DC current demand, surge requirements, cable sizing, fuse protection and BMS limits.
