Where to find buy lithium battery cells
Bargain and settle with the operator. Taobao is the largest online retail and business district in the Asia-Pacific region. It was founded by Alibaba Group in May 2003. In Taobao, there is a situation where the lithium battery cannot be returned after being purchased, and Taobao officials continue to give in. This can be negotiated and reconciled with the operator. By the end of 2011, Taobao's daily transaction volume reached a peak of 4.38 billion yuan, creating 2.708 million direct and full employment opportunities.
To purchase genuine lithium battery cells, it should be more reliable to purchase them from an authorized official agent. There are many batteries available. For a more reliable recommendation, go to a merchant on Alibaba that sells battery cells. But to be honest, if you process and sell finished batteries yourself, it is not profitable to buy directly fromnew batteries. You can buy imported disassembled batteries, which are quite cost-effective. And the lifespan is also very good. It's just that after buying it, you have to measure everything yourself, which is more troublesome.
