BATTERY FAQS

LiFePO4 Battery Frequently Asked Questions

Answers about lead-acid replacement, system compatibility, OEM battery development, certifications and wholesale orders.
Can LiFePO4 batteries replace lead-acid batteries?

Many LiFePO4 batteries can replace compatible lead-acid deep-cycle batteries in RVs, boats, golf carts and industrial equipment. Before installation, confirm the system voltage, battery dimensions, terminal layout, charger profile, maximum load, cable size, fuse rating and operating temperature.

Are LiFePO4 batteries compatible with existing chargers and inverters?

Most LiFePO4 batteries are compatible with standard 12V, 24V, 36V or 48V inverters when the system voltage and power requirements match. Many modern chargers also include a LiFePO4 charging profile. For lead-acid replacement projects, confirm the charger voltage, inverter rating and maximum load before installation. A compatible charger or DC-to-DC charger may be required if the existing charging equipment does not support LiFePO4 batteries.

Can you provide custom or OEM LiFePO4 batteries?

Yes. OEM and custom battery support can include voltage, capacity, BMS settings, enclosures, terminals, connectors, communication protocols, labels and packaging. Send us the application, electrical requirements, installation dimensions and expected order quantity for review.

What is the minimum order quantity for wholesale or OEM orders?

MOQ depends on the battery model, specification and customization requirements. Standard models may be available for sample testing, while custom enclosures, private labels and OEM production normally require a confirmed order quantity. Contact us with the model and required quantity for details.

What certifications and battery documents are available?

Available certifications and documents depend on the battery model and destination market. Supporting documents may include UN38.3, MSDS, CE, RoHS and product test reports. Confirm the required documents and target market before placing an order.

What are the production lead time and shipping options?
