Balancing Act

I did two test runs again today, just short 3 miles runs, but my batteries are quite unbalanced. I also fixed the vacuum leak and properly connected the Curtis 1400E DC/DC Converter. The car is now drivable, except for the battery issue.

Right now I am charging each battery with a 10 AMP smart charger, one at a time. I have everything setup under my tarp and I will not drive it until each battery has been fully charged with the smart charger. Then I will take it for a good 6-8 mile drive, and charge it again with the main K&W BC-20.

The batteries became unbalanced due to sitting for 3 months, and having the PakTrakr sucking power from 2 of the 8 batteries more than the others (remotes and display).

Once this Balancing Act is complete, I will start to take new data for range and performance. I did take it up to 40 MPH this morning with no problems, even with the unbalanced pack. I am also working on installing the BC-20 into the trunk of the EV. I haven't spent much time on it yet, but I do have an idea that should be very easy, assuming I can get a marine 110v plug for the gas cap connection.
