Hello my name is Gabe and I am new to this forum and I was hoping to get in touch with someone who has a grid charger/discharger that I could borrow. My car has all the symptoms of an inbalanced battery and I want to get it back to good working conditions without having to swap out for a bumblebee pack. The pack that is in there was changed out a little over two years ago. Any help would be appreciated. I live in the north bay Vallejo ca.

 

Before you even attempt grid charging, disconnect your 12V for 60 seconds and reconnect it.

Rev to 3500rpm and hold until battery reads full.

Pull the IPU lid (steps 1-9):

Let it rest overnight.

Locate the BCM connector SHOWN in step 13. Of the two silver boxes on top of the pack, it's the left one - the gray connector with several color wires sprouting from the thick orange cable.

WITHOUT UNPLUGGING THE CONNECTOR, check the 10 voltages and report back. I flipped the connector so it's in the orientation you see at the BCM:

 

Thanks for the help. I'll get back to you on the voltages. Im at work but I did get the cover off at least.

 

It's important that you use the car to charge to full, allow it to rest overnight (10+ hours) and read the voltages AFTER the rest period.

 

It's charged. Didn't take long at all which worries me. Now i wait

 

Depending on the state of the battery, it may only take a few minutes as charging in that manner is pushing >20A.
