It's raining today so I decided to take the chargers and see why three charge differently than the others. Well I found out. The charger I have are labeled Schumacher SC-600A, and I have three different generations of them. Great, so that means that each generation has a different charging scheme and that leaves me to find out how long each charger takes to charge. They should all be the same though because they are each 6 AMP smart chargers.
And I have a plan on how to do that: I know that three chargers have the same exact charging scheme, so I will use those on the front three batteries. The other 5 chargers will be used on the rear batteries.
This weekend I plan on taking the control board out, build the front battery rack, install the vacuum brakes, and what ever else humanly possibly I can do. But before that I will take the EV out for another drive to drain the rear batteries down and then settle in for a nice full charge and hope it doesn't take eternity.
