A Pack Factory That Tells the Truth

We don't make cells — so we're free to pick the best. Every Chengbang pack is built with genuine, Grade-A cells from top brands: EVE, Lishen and Samsung SDI. No refurbished cells. No B-grade. Ever.

Our Story

Our founding team has built lithium packs since 2012. In 2019 we established Dongguan Chengbang Energy Technology Co., Ltd in Tangxia, Dongguan — now 30 people across 4 production lines, producing 500+ packs per day when materials are staged.

For years we served overseas markets through trading partners. Today we work factory-direct with importers, brands and project buyers — same factory, faster answers, clearer accountability.

Our name is on the label, so our rule is simple: honest capacity, honest cell grade, honest lead times. That is why long-term buyers stay.

Battery aging and formation room — Aging & formation room — every pack cycles through full charge/discharge before shipment

Finished packs packed on pallets — Finished-goods warehouse — palletized and ready to ship
