SOK battery is a leading manufacturer and supplier of lithium iron phosphate batteries (LifePO4). Established five years ago by a team of 3 engineers from CALB, SOK has provided our satisfied customers with more than 500,000 cells and 60,000 battery packs, receiving great feedback from them on a regular basis.

Unlike other LiFePO4 battery resellers, SOK designs and manufactures the battery management system, and assembles the battery pack in-house to extremely strict quality control standards. SOK only uses brand new grade A++ matched cells.
