Anyone thought of making your own Lithium batteries? On EBAY you can buy your own cells and make your own. Here is a whole set of 8 cells to make two 12 volt 86ah batteries or one 86ah 24 volt battery for $620. You would still have to purchase a BMS for them though. Depending on which one you buy that could add around 100 bucks to the total. $620 dollars is a extremely attractive price. I have looked into this briefly and from what I have been able to gather is that the all of the battery LiFePo4 cells are made in china. Companies I assume have them built to their specs. Ship the cells here and assemble them. Maybe get a discussion going to see what the pit falls could be going this route.
