Frequently Asked Questions
What cylindrical cell formats does ASOL supply?
ASOL supplies 18650, 21700 and 26650 cells in Li-ion and LiFePO4 chemistries, as loose graded cells or assembled into packs with a BMS.
Do you sell loose cells or only finished packs?
Both. You can buy graded loose cells for your own assembly, or have ASOL build spot-welded modules and complete packs with protection.
Can you match and grade cells for consistent packs?
Yes. Cells are capacity- and resistance-graded and matched before assembly, which is essential for balanced, long-life multi-cell packs.
What certifications apply to the cells and packs?
Shipments are certified to UN38.3 with CE and RoHS compliance; UL is available on selected assembled products. Test reports are provided on request.
What is the MOQ and lead time?
MOQ and lead time depend on the cell type and order size. Contact us with your format, quantity and target spec for exact figures.
How do I request a quote or datasheet?
Email info@asolbattery.com or WhatsApp +86 15779858703 with the cell format and quantity you need. We typically reply within 4 hours on business days.
