So, I've built my 8A as a day VFR only ship with no lights and no gyros. Just about everything I find on sizing batteries seems to be about keeping your all electric panel alive while you fly home on a dark and stormy night. After starting the engine, I all need the electrical system to do is talk on the radio and run the flaps. Could do without either in a pinch. I figure the starter is the only serious draw on the battery.
How many amp-hours does the starter need? I don't find any good numbers for the starting current, everything just says hundreds. 300 amps for 2 minutes (should be enough for several start attempts) give 10AH. Would that be enough? Any one have experience with this kind of minimal system?
I could just get the PC680 everyone recommends in past threads, but wondering if I can save a few pounds and dollars.
