[Fot] How much electrical power is needed for a 30 minute race.

[levilevi at comcast.net (Bud Rolofson)]

How much battery is needed to run a Spitfire for a 30 minute race without an 
alternator, in terms of amps, or current needed.

I've been looking at lighter weight batteries like the Braile and don't have a 
good idea of what reserve capacity is needed. Is 35 minutes enough with a 
battery capacity of (C/20 rate): 21 amp/hr.

Fuel pump, ignition, some Gage's, and LED brake lights are the biggest draws on 
the battery.

Thanks for any suggestions.
