I have been researching for years about building my own EV and was about to start the conversion on my 99 ranger but the economy went down and my new job is 35miles each way so a commuter is out. Just a background I am a ME and have ready Convert It! by Michael Brown and Build Your Own Electric Vehicle by Bob Brant. The real reason for my post is that I have access to a quite a few 24V lead acid concord batteries. The batteries in question are RG24-11M.
These are not deep cycle but they are brand new and I might be able to get them for practically nothing. Obviously they don't have the amp hours for a commuter EV but they do stand the potential to be a drag EV battery. With the 24V I could put 6 or so of them into a small car or bike with very little weight but still run 144V. My question is for all those battery gurus out there is; are these even worth bothering with? I know that they wouldn't last long but for a drag bike or car could I get a couple dozen runs out of them? My main worry looking at the specs is that I would burn them out during the first attempt but I figured this could be a cheap way to dip my toe in the water of the EV world.
