ThanksHave you thought about possibly posting some photos of your build and how you carry it on your scooter? I think it's fascinating what you have accomplished and the care you have put forth to protect your cells without a BMS.
Actually, I think I figured out a secret about paralleling them. That was the second time I did this. And the last time it went pretty fast as well.They will drift. Paralleling cells without current flow transfers almost no charge. Current flows when there's a voltage difference. When you parallel them, their voltages almost instantly equalize. There is an initial surge and then it drops to low milli or micro amps. If you do this for weeks, it can be meaningful, but doing it for 2.75 hr is just a placebo.
Once you series them and subject them to a charge/discharge, they will diverge again.
I had hoped to use a power supply that I have to maybe try to charge them when in parallel, but I found out it does not work so I threw it in the garbage and went with the 24 volt series charging with the lead acid gel charger instead.
However, even the last time I did this they remained equal UNTIL I started to charge them again.
But while discharging they remained all equal.
It was only when charging that they diverged.
And as I have said in numerous threads that you have read.Technically, the one good thing about paralleling them in your situation is it serves to pull the 4.04V cell down. Please try to avoid pushing cells that high.
And as I have said in numerous threads that you have read.
I do not have a BMS or relays or even a proper charger.
So I can't "avoid pushing the cells that high" at he moment.
You should know this by now.
It is obvious from the comments that many here never actually read what I say.
It might be wise to just no longer bother.
I mean why bother writing out in detail things if only two or three are going to bother to even read what is written.
I do not have, and have never had a 12 volt power supply.
Ah ok, got it now. I never really considered that as a charger though. And as it is broken I never used it.You indicated you had this power supply:

Describing it as a 12V supply isn't outlandish.
