Sanj, that's a pretty good answer ! If I was to recharge a battery with a 30% charge still left in it, the charger still starts from zero so it makes sense your explanation.
As for equalizing the cells, I never thought of that and I see why it may be important to have one of those discharge trays !
So what do you think about my YOKOMO YR-4M2 photo ? Like it ?
Can't wait to race it.
