This morning, I drove the Electro-Metro to drop my wife off for her car pool.
I have been working a lot lately, all farther away than EV range, so I really haven't had a chance to test the new batteries yet.
One battery seemed a bit off when I tested it before, so I checked it with a volt meter before leaving. Yep, it was down to 12.45V.
When I got back, I checked that battery and it was WAY LOW! (below 10.5V!!!)
As were TWO OTHER of the new AGM batteries.
I am manually recharging those three batteries right now with individual chargers, and we will see how they perform after that.
I would love to run the car at 144V. I still have a few things stopping me.
One is just mounting 12 batteries. I already have 1 in front, 5 in the back seat batt. box, and four across the trunk space. I still need two more to go to hit 144V. Looks like it's time to build a front battery rack under the hood!
I also picked up two faulty 72V chargers. They only "float-charge" right now. Apparently, these chargers are mounted the wrong direction in the vehicle they come in. Then the heat sinks don't work right and it melts the solder in a certain place on the board. Supposedly, if I crack them open and fix that solder joint, they should work fine again. Two of them together would charge a 144V pack.
