A Shenzhen LiFePO4 battery factory, not a trading desk
Shenzhen Sike Power Technology Co., Ltd. builds LiFePO4 battery packs in Da Peng New District, Shenzhen. Cell grading, assembly, aging, test and inspection all happen in house rather than being subcontracted out.
Publishing capacity, case dimensions, BMS rating, IP rating and cycle life for every pack is a deliberate choice. It makes the catalogue harder to write and much easier to buy from, because the buyer can check the claim against the application before ordering.
Why Buy From Us
Grade A cells only
Graded in house before assembly, because cell matching is what decides whether a pack reaches its published cycle life.
Everything published, nothing implied
Capacity, case dimensions, BMS rating, IP rating and cycle life are stated on the page for every pack.
Aging and test before packing
Cell grading, assembly, aging, test and inspection are all done in house, so a fault is found here and not on your site.
OEM and ODM
Packs built to your case, label, BMS choice and communication protocol, as a normal part of the factory's output.
Send us the application and the load
Tell us what the pack has to power, for how long, and which inverter or charger it works with. You will get a sized recommendation with capacity, dimensions, BMS rating and cycle life in writing.
