Can LiFePO4 Batteries Be Switched Parallel Or Series?

Yes, make sure the batteries are fully charged and all batteries have the same voltage level before switching them in series or parallel. We do not advise mixing serial and parallel circuits.

What should I do if the battery cannot be charged and unusable?

Our battery BMS has multiple protection functions to ensure safety: Short circuit protection, over-current protection, overload protection, over-voltage protection, overcharge protection and over-discharge protection. Once protection is triggered, the battery is temporarily unusable.

AI-Powered supplier vetting

SummaryThe supplier is identified as a factory in Shenyang, with a business scope covering mechanical equipment, metal products, assistive bicycles, scooters, spare parts, tools, electronics, building materials, and technology import/export. It reports 90% export sales, five years of export experience, self-operated import/export rights, OEM and ODM services, and customization from customer designs. Service strengths include participation in an offline trade show, multiple quotation and payment options, and a complaint-handling procedure with records. However, it reports no inventory, overseas warehouse, showroom, agent, or branch capability, and zero countries offering overseas services. Supplier-service assessment lacks written procedures and records for corrective actions. R&D information indicates no new products in the past year, no SDK, and two R&D engineers. Quality-control evidence is incomplete, with zero listed testing equipment and unknown assurance and traceability status. No certification holding or...

Supplier typeThe supplier is explicitly identified as a factory located in Shenyang, while its stated business scope spans mechanical equipment, metal products, mobility products and parts, tools, electronics, building materials, and technology import/export. This supports classification as a manufacturing-oriented, broad-scope industrial supplier.

After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with followed records and reports eight qualified suppliers for service capability. However, it has no in-stock service, overseas warehouse, showroom, overseas agent, or branch capability, and its service-capability assessment and corrective-action records are not documented; overseas service coverage is stated as zero countries.

R&D capabilityThe supplier provides ODM services and has two R&D engineers, but it reports no new products in the past year and no available SDK. These findings show some design-related capability but explicit weakness in recent product innovation and software-development support.

Customization capabilityBoth design-service records state customization from customer designs and minor customization, while the R&D information confirms ODM service availability. This is explicit evidence that the supplier can support at least design-based, minor, and ODM customization.
