Frequently Asked Questions

Can this battery support high-current applications?

Yes. The standard high-current configuration supports a 200A maximum charge current, 300A maximum continuous discharge current and 400A peak discharge current for 10 seconds. Final suitability should be checked against the actual continuous and surge load.

Can multiple batteries be connected in parallel?

Yes. Use batteries from the same production batch where possible and bring them to a similar state of charge before connection. The final connection plan should be confirmed for the selected system architecture.

Does the battery support APP monitoring?

APP monitoring is available with the 300A BMS configuration. Final monitoring functions should be confirmed before ordering.

What charger should be used with this battery?

The standard charge voltage is 14.6 ± 0.2V. The recommended charge current is up to 100A, while the maximum continuous charge current can reach 200A for this high-current configuration. Charger compatibility should be confirmed before installation.

Can I order one battery first?

Yes. A single-unit initial order can be accepted and will be handled as a sample order. Pricing, lead time and shipping arrangements are confirmed according to the battery configuration and delivery destination.

What is the warranty?

This 12.8V 300Ah configuration is covered by a 3-year warranty. Specific warranty terms are confirmed in the sales agreement.
