Battery Components

First we start with the Cable Assembly and High Voltage Connector Manufacturing Service. Then some customers were also trying to find other suitable battery components in China. However, they don’t know the manufacturers, or can not trust product quality and payment safety, so they asked JONVER for help.

In late 2017, JONVER began to help our customers sourcing battery components. During this period, we found too many manufacturers on the market, totally confused to choose. The only way for us is selecting products proved by market and testing these products together with customers. After around 2 years’ selection, we confirmed 4 component manufacturers to work with. They guarantee your product quality, and we guarantee your payment safety.


JONVER also provide free samples for your testing, you just pay the DHL/FEDEX delivery cost by yourself.
