Katie, I had the very same decision to make a year ago. I decided not to wait the six months necessary at that time.
I believe the question is not whether the controller can be swapped. The question is about range and performance requirements and vehicle design. The advantage of the Zlla is that it allows a much higher performance and some range advantages because it will make effective use a much higher voltages and current. If your requirements are met by a Curtis controller, there is no advantage, in my opinion, to switching to the Zilla. On the other hand if you require the advantages of the Zilla, the Curtis will not substitute in the interim. In other words if you require a 1000 amp system with a voltage far in excess of 144 volts, you can't use a 500 amp 144 volt Curtis controller temporarily without major impact on the design (e.g. number of batteries). If all you need is a 500 amp 144 volt system why would you switch to a Zilla later? If you need a Zilla, order it now and wait. The controller is one of the last components you will install. If the Curtis meets your requirements, there is no advantage to switching. Visit my web site for my planning and conversion experience.

Plug-in, we have the technology, the NiMH powered RAV4 EV is the proof. ----- Original Message ----- From: "Katie Robinson" <[EMAIL PROTECTED]> To: "FLEAA Mailing List" <[email protected]> Sent: Sunday, August 17, 2008 3:02 PM Subject: [FLEAA] Controller swapability? I had another question... I know there is a long wait for the Zilla controllers, if you use something else is it easy to swap for a Zilla later? Probably not the most cost effective idea, but just wondering. —Katie _______________________________________________ Florida EAA mailing list [email protected] http://www.floridaeaa.org _______________________________________________ Florida EAA mailing list [email protected] http://www.floridaeaa.org
