An electrathon is a competition to go the farthest in one hour powered only by commercial lead acid batteries weighing no more than 73 pounds (33 kg) (two car batteries). The record is 62.05 miles (99.86 km) as of February 2011.
To create and develop a sport that improves public awareness and understanding of electric vehicles through continuously improving vehicles and rules.
This held some mild interest for me until learning that only commercially manufactured SLA batteries may be used. From an organization whose mission is:To create and develop a sport that improves public awareness and understanding of electric vehicles through continuously improving vehicles and rules.
What a joke! I mean continuously improving where the main ingredient is fixed in the prehistoric era of batteries? ES ought consider the making of a completely new international race modeled on http://www.electrathonamerica.org, but lift this mind numbing rule.

I will request an Etec brushed for my Elf ... with LIPO's .. Would you agree

We run 24 volts in the form of two Optima yellow top batteries rated at 40 AH (for the 20 hour rate). We usually get about 32 Ah out of them. The race is a 1 hour endurance race where everybody uses the same/similar batteries (1000 watt/hours max). The most laps win. For a motor I have found the Etek brushed motor impossible to beat, and trust me I have tried. I am currently waiting on a controller from Leo to run the transmagnetic brushless motor I bought from an ES member to see where it stands.
We do not use regen, I feel that I can coast better with a freewheel, plus most courses I almost never hit the brakes anyways.
