Isn't that what most RC chargers do when you have the balance leads attached ?Doctorbass said:........The best in that case is to use the balance lead of the charger to monitor voltage and not the discharge lead.. so this way the charger knwo exactly the true voltage of the cell.

I will charge at 0,5C in my real pack, only 1C just now to speed up my test. What C rate do people usualy charge at?Overclocker said:1c charging isn't what people usually do. So your results won't be representative of real-world

Icharger 3010B does measure on balance leads if you have them connected and LVC is based on balance led measurements, not on main leads. My cheap HK eco8 do not do that and I wonder if Turnigys do, BTW balance leads must be at least attached to the battery.Hillhater said:Isn't that what most RC chargers do when you have the balance leads attached ?Doctorbass said:........The best in that case is to use the balance lead of the charger to monitor voltage and not the discharge lead.. so this way the charger knwo exactly the true voltage of the cell.

I use about .5-.25C in real life. You could do some IR tests every hundred or few hundred cycles and one very slow discharge cycle to have real capacity.electricbike said:I will charge at 0,5C in my real pack, only 1C just now to speed up my test.

5 minute wait time is also not what people do.Overclocker said:1c charging isn't what people usually do. So your results won't be representative of real-world
Depends on cell in question. In my tests, panasonic B type died after 30 cycles, while LG D1 did 500 cycles to 80% capacity on same conditions (1C charge).Overclocker said:i believe 1c charging leads to rapid cell deterioration. so in the end your results may not be very useful. max 0.5c should be ok
Yeah well I am not too sure about all this, I charge my 18650 pack often over a 12 hour period over night. And its currently 7P configuration and I am rebuilding it to 8P on a 500w S12S/Bafang setup so its not going to draw a lot from each single cell either. I only use a PAS setup these days and I often go riding on pretty tame speeds as well with assist level only being 2-3 most of the time.circuit said:5 minute wait time is also not what people do.Overclocker said:1c charging isn't what people usually do.

So in the end these test show nothing useful, just to compare the cells one to another. But results in real world are very much different.
