So what BMS are people using with the batteries you are selling and how much does that add to the cost? With your strong opinions about having to use a BMS I am surprised you are willing to sell the modules without an appropriate BMS as part of the deal. Are you providing any warranty or after sale support? It seems as if you are using lack of BMS and warranty support as a negative to the Chinese cells, yet wiling to let people walk right down the same path as long as they buy what you have to offer. I hope to buy lithium for my truck some day and feel that even with their flaws the Chinese batteries are at least a known commodity at this time. Buying raw cells meant for a Leaf or a Volt without the hardware or firmware they were designed to be used with sounds a little sketchy to me, if for nothing else, just for the lack of expertise available. I remember how some of the first people to try the Chinese cells got burned back in the day :) Now at least there is no lack of opinions about how to use them properly and plenty of real success stories. I remember David Nelson bringing his TS cells to my house to work on them together before he stuffed them into his Gizmo several years ago and I see that for his application, his cells and approach to maintaining them has worked out well.
