I got the same batteries and they are still in the boxes. They were all at 3.331 volts when they got here,now they are at 3.328volts. It has been 2 weeks now.
I am still doing some restoration work on the car. I am using floodies to move it around while working on it.
Yes I charged my pack yesterday. I installed 32 cells in two packs of 16 cells under the seats of my VW. I am using two Meanwell 48 volt power supplies in series. They can be adjusted and I have them set for a total voltage of 117 volts (3.65 per cell) I never saw the Amps decrease from the 11 amps I started charging with. They are now resting at 3.43. I am monitoring them with cellogs using a cellog board RWaudio sold me. I have one cell in the group that got to 3.70. My power supply won't go any higher so I think I am being conservative.
I have an EV Display which I bought from EV Werks and I can track Amps, Volts and Amphours. I also use a light objects programmable voltmeter that I can set to turn off the charger when it reaches a particular voltage.
I should add that I did cycle one of my unused cells with my Power Lab. I don't have the voltage detail but I got 47 Ahrs into one of the new cells and on discharge, to 2.8 volts, I got 94.5 Ahrs out of it. That would lead me to believe that they came to me at about a 50% charge leveI a My graph didn't save so I don't have other details. I will try another cycle but since I am limited to 6 Amps charging current it is going to take a long time.
