[RE-wrenches] Solar Golf Cart

Sat Aug 16 20:22:37 PDT 2025

Here's some EVs we put solar on.  Check out the Solrunner, the early one 
was a golf cart, then the other was a chinese UTV we converted.  I 
haven't done anything in a long time, but I recently got a Surron 
electric motor cycle, its a bunch of fun.  Li+ batteries make any EV 
much more usable. more range, lighter weight.  Lead acid is just rough, 
performance starts dragging as the voltage drops in the first few miles.
