Quite right, I've been following these debates for many years. I have one point (or more of a question really) that I can't really get over as to why to go with the AC over the DC. Can AC controllers function as voltage transformers in order to allow the use of a higher voltage battery pack in order to compensate for battery sag that might keep you from achieving max power and holding that power to max set RPM in your controller output. For example a modern 300V input DC controller can easily be set to an output voltage to match a lower motor voltage requirements. 250V in 170V out for a 9". The advantage here would be to reduce battery currents and keep them within their proper C ratings. This way you get every Kw of controller you paid for right up to your set RPM. Does this make any sense or have I missed something? Is there a lack of flexibility with AC or do I just have to plan better?

This takes me back to 1996! Nothing like a good old fashioned EVDL AC vs DC debate. ;-) Maybe we can also revisit the flooded vs AGM battery battle. ;-) David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
