So initially when I built these battery packs I decided I was going to allow my RC car charger to balance them in series as it has the ability to do active balancing
However it became obvious that the RC car charger really wasn't the best option for something like this..
So I purchased a 10 amp variable regulated power supply from Amazon think it cost about $50
I pulled all the bus bars off and wired all eight cells in parallel it looks pretty damn Goofy
Then I powered up the power supply and connected it to my Amprobe multimeter and adjusted it to 3.65 volts.. which interestingly enough according to the display on the power supply is only 3.6 volts.. but I feel like my multimeter is probably more trustworthy
From there I took a voltage reading of the entire Bank and I don't recall exactly what it was but it was something in the 3.5 range nearly 3.6
Anyway when I first hooked it up the amperage was somewhere around 3:00 to 4 amps going in if I recall correctly.. it is now at 0.092a and approximately 0.327w
Have I reached the point now where I can consider this to be properly top balanced or should I continue to allow it to do its thing or.. should I disconnect it let it rest for a little while and hook it back up and go at it again?
