I thought someone contacted you about there Nissan Leaf battery packs. I click up there site that was sent to you (hybrid auto center.com) and one battery pack is rated at 182V nominal at 12kw/h. Contains 24 modules at 7.8V/60ah each for $2490.00 each.
On my next battery pack, I might use these for my EV that weighs 7010 lbs with the existing 2400 lb 180v 250ah battery pack. Parallel three of these packs for 180 ah at 182 volts that weighs 630 lbs for $7470.00. This pack will make my EV weigh at 5240 lbs which I estimate will give me a 25% increase in my range.

Sadly, it looks like "go fast" is coupled to the other two.... Thanks to the people here, I've spent a lot of time today so far searching and crunching numbers and the like -- dozens of batteries from half a dozen vendors and as many manufacturers (including CALB, Enderel, GBS, and more). I'd appreciate if somebody can check my math on the current leading candidate. It's a Voltronix 3.2V 60Ah 8C cell that EVWest sells for $78 / ea: http://www.evwest.com/catalog/product_info.php?cPath=4&products_id=266&osCsid=ph57045uael6qb57sjjaqi8cs3<http://www.evwest.com/catalog/product_info.php?cPath=4&products_id=266&osCsid=ph57045uael6qb57sjjaqi8cs3> If I have the math right, if I were to connect 45 in series, that would make a 144V 60Ah cell. Three of those in parallel would make a 144V 180Ah battery capable of 1440A discharge and thus 207kW power with a total capacity of 26kWh...at a total cost of $10,530 and a weight of about 750 pounds. Does that math sound reasonable? That's twice the capacity I need, which obviously in and of itself isn't a bad thing. But that's over twice the cost I had previously been guesstimating -- and doesn't include a BMS or charger or the like. And it's a *lot* of weight. But if I cut back on the number of cells, I cut back on either voltage or amperage (or both).... It looks like a GBS system in a kit with BMS and the like would likely get similar performance with half the capacity and a third the weight...for twice the money. Enderel looks to be about comparable to GBS but maybe lighter and more expensive still. So...um...am I missing anything? Thanks again, everybody. b& -------------- next part -------------- A non-text attachment was scrubbed...
