Battery question

[Riven]

I was going to do a dual for triple bat mad but just looking i could get more in this ZZ but i dont really know what the motor can handle

I hear alot of people do dual. some do 3 but really rarely i hear of a 4. Is this just to much juice?

How much will using dual bat effect motor life? 3 cell? 4cell?

How much faster is a dual with the same motor?

i wired up 2 cells neg to pos then to the motor but it seems no faster im confused
