88 40ah Thunder-Skys and a Ziila 1k = ?
I have the opportunity to purchase 88pcs 40AH Thunder Sky cells, Generation 2 cells. They are resting at 3.2V. The cells were purchased in November of 2008 and arrived in on January 2009. I would run 2 packs of 44 (140 V x 2) in parallel (80 ah combined). There are approximately 5-6K miles on them. Priced at $2500 plus shipping costs. I am running a WarP9 with Zilla 1k in a 1,100+lbs sandrail at 144 V. Is this a good deal? Worth the risk that they may last several more years? Will they work with my setup? My major concern is; I was told NOT to allow the Zilla to run over 500 amps because if I hammered it into higher amps it would ruin the battery pack within a week with 40ah cells. Should I go for 70ah or 100ah instead? I would like to get the most acceleration without damaging the pack and a minimal range of 40 miles (running both packs). Also, should I buy 4 more cells to get to 144 V per pack? How do I charge both packs or should I create one 294 V pack/40ah and limit voltage from controller? I have a short time to make a decission. Thanks.
