Next up is making a battery tray for the helicycle. I had decided to use a Odyssey PC925 battery, since it seems to provide a nice compromise between capacity, size and weight. I made a box with the battery dimensions and started to brainstorm thebest way to mount it. The battery tray needs to hold the following components -Battery -Master shut off switch -Exciter for turnine electric 40 amp-solenoid for engine starter
