Company

A Shenzhen supplier focused on two lithium chemistries

Sunder works with lithium iron phosphate and 18650 lithium-ion — and deliberately little else — so the team can advise on cell choice rather than simply take orders.

What we do

From our office in Longgang District, Shenzhen, we supply LFP cells and packs together with 18650 cylindrical cells in several grades. The customers are overseas importers, wholesalers, system integrators and brand owners, chiefly in Europe, Southeast Asia and the Middle East.

Those batteries go into solar storage and solar street lights, electric wheelchairs and e-bikes, electric lifts and other e-mobility, power tools, household appliances, consumer electronics and industrial equipment.

Any shipment can be accompanied by the usual export documents — UN38.3, MSDS, CE and RoHS — when you ask for them.
