⚡ 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 ratings, 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.

---

📐 620AH IN A COMPACT HIGH-CAPACITY PACKAGE

The battery body measures approximately 408 × 310 × 262mm, with stated overall dimensions of 458mm L × 310mm W × 262mm H.

This provides 620Ah of energy storage in a package specifically designed for caravan, motorhome and off-grid systems where battery capacity needs to be maximised without unnecessarily consuming storage space.

❓ QUICK FAQ

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

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

What charging profile does the battery 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 DC current demand, surge requirements, cable sizing, fuse protection and BMS limits.
