Yes, somewhere in that timeframe there was a huge drop in price, probably because Sky Energy (now CALB) entered the market and Thundersky had some competition. Back then I priced out a 108 volt pack for a Miata from Thundersky and it came to $15k. The last few years, though, the prices seem fairly stable at around $1.25/AH although I think the cells keep getting better. In that way the price is "dropping" because we pay the same but get a better pack. That Miata pack used 180Ah cells mostly because I needed big cells to get the amps I wanted. Today I would use a pack of CA100's instead. They'll do the amps I need and only cost $4000 (and sacrifice range, of course). --Rick _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
