Did come across this company, Belive they make the pouch cells being sold by bmsbattery for us ebikers & a lot of other stuff not stocked by bms as not applicable to ebikes, too heavy duty. I have some of these pouch cells on order to make a 9.5 Ah ebike batt, so am the guianea pig here. Have a look round the site. (bms - introduced smaller cheaper 8 Ah cell just after I placed order. Pity none of these people seem to offer sea rather than air shipping as this really ramps up the price

Belive Chevron Texaco own the patent of A123 cells, bought either to give them a future once all oil is gone, &/or so they can control the applicaton of these cells into ev's - thus keeping us dependant on ever more expensive oil for as long as poss. This is why you can only buy A123's in silly little sizes & end up putting them in parallel groups
