I was on another forum (endless sphere) asking this, but I wanted some more unbiased opinions. I'm building an electric motorcycle (well, it's built). Motor is Mars ME0913 72v and the controller is an Alltrax 7245 (450 Amp)

My goals: 45 miles while maintaining an average speed of 45-55 MPH. I'd like to be able to do a few mile bursts of 65-70 MPH should I need to take it on the freeway.

I'm down to 3 battery choices: Lead-acid, LiFePO4, and LiPo.

On endless sphere everyone (literally EVERYONE) pointed me away from lead acid. It seems Lipo, with all of its dangers, was still a better option than lead acid. It seems everyone had their own views on which battery was better. LiFePO4 fans were against LiPo. Lipo fans were against LiFePO4 (because of size and cost). But it seems all were against lead acid, though I couldn't get a better reason other than "they're heavy". Which it's hard to argue against.

So lead acid: readily available, reasonably priced...but heavy. Is it worth it? The bike is a 1996 Honda CBR 600 and I can fit about 6 yellow optima batteries.
