Thanks Mike, I've already begun to consider this. I've now got a source for a "special" ADC 8" that can handle 192V easily. It's been beefed up, apparently it was a limited run from ADC. It sounds kind of like the XP-1227 to me, but I don't have the exact model number yet. This motor would let me keep my 8" adapter plate and still go to 192V, while drawing less power than a 9". How does that sound?
I talked to my battery supplier about the Optima group 31s today, he said that they were supposed to come out in April but that their release was pushed back. They're supposed to arrive sometime in the next month or so, but their initial prices will be astronomical! Their web site says $200 each, but he said they'll probably be selling for more like $290! Ouch. Later, Matt On Wednesday, August 14, 2002, at 05:37 PM, Mike Chancey wrote: > Hi Matt and all, > > One thing you need to be aware of is the maximum voltage your drive > motor can handle.
