⚡ HIGH-CURRENT PERFORMANCE

The stated 330A continuous discharge capability gives the 280Ah battery substantial current capacity for larger auxiliary systems.

This makes it suitable for appropriately designed high-power inverter installations, but the complete system must still be sized around actual inverter DC current, surge demand, cable size, fuse protection, connection quality and BMS limits.

---

🔌 CHARGING REQUIREMENTS

The supplied specifications recommend a standard charge current of up to 100A.

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

If your charger offers a LiFePO4 profile matching these voltage requirements, that setting can be used.

Lower-output compatible chargers such as 25A, 30A or 40A units can also be used, although recharge times will be longer with a 280Ah battery.

❓ QUICK FAQ

Can I replace an AGM battery with this lithium battery?

Potentially, but your complete charging system must be lithium compatible. Check your DC-DC charger, solar regulator and 240V charger to ensure they support the required lithium charging profile before replacing an AGM battery.

What charging profile should I use?

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

What size DC-DC charger can I use?

The stated recommended standard charge current is 100A. Smaller compatible chargers such as 25A, 30A or 40A units can also be used, but will take longer to recharge the 280Ah battery.

Can this battery run an inverter?

Yes. The stated 330A continuous discharge capability makes it suitable for appropriately designed high-current inverter systems. Actual inverter suitability depends on inverter DC demand, surge requirements, cable sizing, fuse protection and the complete electrical installation.

How do I recover the battery after a low-voltage BMS shutdown?

The supplied instructions describe using a lithium-compatible 240V charger with a suitable power-supply mode to wake the battery. Battery and charger manufacturer instructions should be followed during recovery.
