How do you ROLL

[member3480]

Need some suggestions on batteries and how has your experience been with it. I plan on doing a couple bikes but got to get this one out of my garage first and need a good small battery that will do electric start. Battery box under seat is only 3" high and I still have to make it. What have you done

I'm using an earthx etx12 battery. Runs the estart and EFI no problem. Does crank a little slow when the temps go down, but has over and undercharge protection built in.

When I was hanging out with an ultralight group they were using the batteries that were used in those road construction yellow flashers. They were using these as total loss DC power, 1/2 hour flights mostly. How they acquired these batteries, I cannot say.
