ok long story short,
me and some guys are building an aircraft (ultralight) and we want the engine to be electric. we are still deciding whether we will have 2 180V or 2 240V motors, but we still cant find the right batteries for them. car batteries are cheap, but they are very heavy. lithium ion batteries last long and deliver more power, but are more expensive. is there a battery that can give out a lot of power, stay light, and be inexpensive (car battery inexpensive, but i can pay for a little more)?
