I have started charging up the cells to give them a test discharge and so far its not going to well. The worst one was only 85Ah discharging at 10Amps, I'm trying it again at only 5Amps. Others have been about 95 Amp hours. They get a bit hot charging at 30Amps?

I'm a dude playing a dude disguised as another dude.
I would be happy if they were all around 100Ah or I might be finding out how good the aliexpress 29 day money back guarantee is. Just in case I'm doing something dumb here are the charge and discharge settings.
Thanks. I charged it up a bit and discharged it and it seems to be functioning OK. I thought there was not much room in there I''m to angry with myself to deal with it now. I will try and fully charge it tomorrow.
Having muscular dystrophy fucking sucks, before I would have had no problem with this sort of thing, now I have to use both hands to be able to lift one cell and I have to rest my arms on the chair's armrest.
Looks like I picked the wrong week to quit sniffing glue.
In an ideal world yes, but it confuses people. Also balancing at 3.4 volts balance start can unbalance a pack... So must never be left set to that for subsequent charges.
3.600V Is already lower than the 3.6 to 3.7v (3.650) that the manufacturer says is safe. And most BMS allows up to 3.8 or more in repeated spikes as they slowly balance for hour on hour...
Wise move. If not using longer, take out 10Ah. If not using for a week, take out 1/3rd the packs Ah.
Now, dans presets... Charge each CELL individually with the single cell preset, BEFORE assembly. Then use the 100Ah or the 200Ah preset to charge with balance wires connected.

YOU don't want the fullest cell lingers at high volt for prolong period.
" It is meant for the FIRST charge only . It hasn't completed yet. Change it back to 3.6V, and finish the rest of the charge. "
