Founded in 2014 — 12+ years focused on 26650 LiFePO₄ cells and custom PACKs, serving customers in 100+ countries.
What is the minimum order quantity (MOQ)?
Standard products ship from stock with no MOQ. Custom projects are evaluated by project review — typically from 100 units depending on configuration.
Do you provide samples?
Yes. Standard samples ship from stock; custom samples typically within 15 days after specification lock.
What is a 26650 cell?
A cylindrical lithium cell of 26mm diameter × 65mm height — balancing energy, discharge capability and thermal safety for industrial applications.
How do I choose the right cell model?
We offer 9 LFP and 1 NMC 26650 models. Our engineering team helps you match chemistry, capacity, discharge rate and temperature range to your application.
Can you develop a custom BMS?
Yes — 25+ dedicated BMS engineers covering 2S to 160S with CAN, RS485, UART, SMBus, Bluetooth and daisy-chain protocols.
Which certifications can you support?
UL, IEC, CE, UN 38.3, BIS, KC, PSE and CB — with local compliance assistance for your market. Products serve 100+ countries.
What is your quality track record?
300M+ cells shipped with zero explosions, fires or leaks. IATF 16949 certified with 6 Sigma (DMAIC, FMEA, DOE, MSA, SPC, 8D) methodology.
What warranty do you offer?
Warranty varies by product. All products are covered by Ping An product liability insurance; specific terms are confirmed in the quotation.
How can I obtain test reports?
Download from the Download Center or contact sales — full test reports and certificates are available for qualified buyers.
How consistent are your cells?
100% inspection with batch capacity deviation under 3%, plus full traceability through Cell MES, PACK MES and Cell BDM systems.
What is the customization process?
Six steps: requirements → review (3–5 days) → prototype (15 days) → approval → mass production (30–45 days) → QC & delivery.
What are typical lead times?
Prototype: 15 days. Mass production: 30–45 days. Standard products: in stock.
Do you support OEM / ODM?
Yes — full flexibility on branding, labels, packaging and firmware. 1,000+ custom PACK projects delivered.
What information do you need to quote?
