About 

 Power Technology Co.,Ltd is a is a high-tech enterprise in national key field, which is specialized in developing, producing, selling lithium polymer battery and battery pack, BMS, PACK, and high-quality and high-rate starting battery. The product application field range from EV to HEV, including bus, PCV, SUV, golf cart, city delivery vehicle, mail truck, electric garbage vehicle and so on. Meslen Power is planning to launch a series of products which can provide power for electric vehicle and motorcycle. Besides,  Power also aims to make the products to be solar-powered and compact, thus  installing them into portable equipment so as to mitigate the environmental issues caused by lithium battery scrap.


Battery quality control for after-sale
 
All of  battery cells in a pack are with very high consistency.In a pack, each cell has its own sole electronic code(ID number) for quality control after-sale. Assume one cell in a pack is damaged in any reason after several years later, we could provide a exactly same cell to the client to replace this damaged one(same voltage, capacity, impedance,etc.), in order to make sure all of the cells in this pack with very high consistency.  has a strong system working for this.
 
 Customer Feedback
 
We are happy with your battery quality. I've also been very happy with your good support,
let's continue discussions and work on more,tks.----Michael (from Berlin,Germany)
