Is it better to use two 100Ah batteries or one 200Ah battery?

While capacity is the same, two 100Ah batteries are better. If one fails, you still have the second one. You also have options for parallel or series connections for 12V or 24V banks.

How many batteries do I need for 17kWh daily power usage?

You would need approximately 15 of the 200Ah batteries (or 29 of the 100Ah batteries). You also need about 20kWh of daily charging capacity to accommodate inefficiencies.

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.

Product Q&A

Q:How long is the warranty period?

Normally 5 years according to the application. Lifepo4 cells come with a 3-year warranty. If there is any quality problem, we can send a new one to replace it.

Q:What is the Minimum Order Quantity (MOQ)?

There is no MOQ for samples. For big batteries, the MOQ is 50 pieces, and for small batteries, it is 100 pieces.

Q:Do you accept OEM/ODM services?

Yes, we accept OEM and ODM for your own brand and design.

Q:Is this lithium battery safer than lead acid?

Yes, lithium batteries are much safer as they have a BMS to prevent overcharging, over-discharging, short circuits, and high temperatures.

Q:Can I replace a lead acid battery directly with this lithium battery?

Yes, the lithium battery can be a drop-in and plug-and-play replacement for original lead acid batteries.
