Bought from Shenzhen Basen via Alibaba

Did you parallel top balance the cells? The common commodity cells we buy are not matched for capacity. Don't know why your busbars are getting hot. Did you lightly sand the terminals. Also there will be a slight burr on one side of the busbar because the hole in them is stamped out. That slight burr needs to be sanded off.

I thought I would start a thread on this company so others can add or learn from experiences from this company. I purchased (4) 280Ah cell from Shiela at Shenzhen Basen on 6/22. Communication was very good and at the time they offered a sale price of 5% off. They do list paypal on alibaba but pushed credit card as a better means. She did say that it would be a 4% charge for paypal. I went ahead with the credit card and it cleared and now i'm just waiting for them to be shipped. I will come back for more updates soon.
any updates?
