Some advice and words of wisdom please.

[twizz0]

Hello all, I have been doing alot of searching and reading on this site for about an hour now and I think I am almost there with what I need but I just need 'Some advice and words of wisdom' if thats ok.

Firstly what i need help on is I have an E-Maxx at the moment but I will soon be going over to an E-Revo and I am looking for a little motor-speedo help. I know 100s of other people have asked this same question and I think most people answer with Quark 125B speedo and a Feigao 10XL motor (i think Feigao anyway) but i have a few questions. Everyone is talking about the number of lipo cells that they run being 4cells and 6cells. Now is that 2 sets of 3cell packs runing in parrallel or one 6cell pack? as a 6cell set of lipos would be 22.2volts!!??

Thanks for your help
