Just need some advice on this please. I replaced all my NIMH AA's with Eneloops. Now I'm sitting with a lot of unused batteries. I don't like to waste so I thought of a way of using them. I want to use them in my Dolphin, currently running 6 AA's on the HPR71.



But in order to increase runtime I want to make up 2 packs of 6 cells and connect them parallel. But the problem is here. One pack will be 6X 2700mah Unicross and the other pack will be 6X 2000mah Energizers. Will I run into problems?
