I have .46 engines and they start relatively easy....I don't usually fly for more than 4 flights...I have a field charger but I didn't use it even once last season. In this case I just might stick to the hobby battery, if I'm not mistaken the motorcycle batteries are like $30+ the hobby one is below $20...
The lawn mower battery costs $19!!!!
But you're probably better off with the smaller batteries concerning your situation.
