I got everything back together and took it for a spin today. ~4 miles, 0 gas, me ->
Now, I just need to monitor the charging cycle to make sure none of the batteries overcharge. I must say, the balancer does seem to let them get quite high. I also have to inquire how low it lets them get so I can be sure it'll disconnect properly while in use. I know my wife won't be attentive enough to turn it off when it needs to be.
