Who We Are?


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, we at SOK have provided our satisfied customers with more than 130000 pieces of cells and 14000 sets of battery packs and received good feedback from them.

What We Do?


We design the battery management system, assemble and produce the battery pack by ourselves. We have also established cooperation with a leading battery manufacturer to sell LiFePO4 cells and a complete solar or off grid application system completely designed by them. Starting in 2020, we will start selling online to bring good quality and cheaper batteries for the retail customers.

Given the highly rated reviews, by professional testers ( Will P) and online via FB and other websites. Everything i have read is extremely positive and has convinced me to purchase at least one of these batteries, even though they are on backorder, over several other big name manufacturers who have items on shelves now.

In late Oct of this year I purchased two 206AMP batteries. Unfortunately at the time, the batteries were delayed do to the pandemic, but I finally received them this week. Throughout the process a representative from the SOK customer service team (Min) kept me up to date on the status of my order and immediately informed me when my batteries were being shipped. Not only was I satisfied with SOK's customer service, but with the batteries as well. Without question I would purchase batteries from them again.

It has been a pleasure dealing with Min. He has answered every question promptly after consulting with SOK engineers.I am now eagerly awaiting the arrival of two 206 batteries.My only concern right now is the length of time it will take for delivery via UPS.Hopefully the quality of the batteries will outweigh the delivery time.Thank you to Min and the engineers at SOK. So far you have been great!Will write more after I receive the batteries.
