Nice ride. Farthest I've went is 19 miles. Looks like the batteries are working out well for you. They'll last a long time if you take care of them. Did you put any padding underneath the batteries? I don't know if it matters or not but I put some foam underneath mine. Sounds like you could probably do 30 miles if you wanted if you took it to maybe 10AH or 10.5 AH.
