I ran accross this product but was curious to know why it says you have to use the same capacity size batteries with it.

I thought that when you do a parallel charge you only needed to make sure the cell count (s count) is the same between all batteries and you just add up the total mAh for your charge current.

I have two 3S batetries I want to charge in parallel. One is 4000mAh and the other is 5000mAh.
