Nah, you need 60V or more to run an Etek

But seriously, I think its about time 48V was considered. I seem to remember that Mentorn decided on 36V just because at the time no one could see how people could run more than that.

Current NiCad chargers that people use put out up to 65 Volts, so there wont actually be much changing.

Note that the current rules state no more than 36V, unless you have the approval of the event organiser...
