Battery and charger headache!

[Boons]

Yet another newbie with a battery question!

I think to be honest that I read too much, and thought too much about it that I have confused myself further!

I have just bought a dex 210 RTR and I intend to race the car indoors. I am willing to spend a reasonable amount for the right stuff.

It seems the pack type, shorty, stick, saddle is personal choice. Why would you have a saddle, so obviously 2 packs instead of a neat one single shorty or stick? And will my speed control be ready for whatever mah etc that I fit, or will it need adjusting?

So as I say, money aside, although not re mortgaging the house, can you recommend a popular set up please - although I guess this is personal choice again!

Thanks all.
