[[[CCs: Context: Probably ~=3D 24V 10 Ah + range]]] Warren Buffet thinks or thought so (although his insights may not always translate into his investment companies sheer technical excellence). BYD are one of the big-3 Chinese secondary battery makers and AFAIR manufacture LiFePO4 for their own vehicle manufacturing as well as for market sale. Whether their product is readily available as cells I know not. Taking another approach, I do not know how good Ping Battery are but recall reading through their material a few years back and their self-belief felt like it might be based on a somewhat more substantial technical basis than greater heapings of self belief from many other small battery integrators. For whatever reason Google Ads has been hopefully putting Ping Battery at the top of the right hand ads bar in GMail in recent weeks, even though I've not looked at their site in a long while. Probably due to ongoing current reference to LiFePO4 in my mail of late. The degree of correlation between technical excellence and appearance on Google ads I leave entirely up to you to ascertain. Ad alongside this email offers: http://www.pingbattery.com/servlet/StoreFront Starts well :-) (even if they have trouble with apostrophes) : Hi, if this is the first time you=92ve heard about us, we recommend that you search=93PingBattery=94 or =93Ping Battery=94 on Google = or any other search engine to find out more about our excellent products, service and good reputation. Time has proven that we are the best LiFePO4 vendor from China. Seems worth a look.
