As the old standard rule, runtime decreases when you add cells. This is based on the fact that the amp draw will go up with the higher voltage, and assumes all other variables are the same. Given the same exact setup with the only change being higher voltage, then yes the motor will suck more amps and runtime will be less.

BUT.... there are soooo many variables that you can't really make a blanket statement like that.

Usually when we talk about running higher voltage setups, this assumes a different motor/gearing etc. So it's apples to oranges.

Higher voltage with a milder motor can give longer runtime... sometimes much longer. Plus the higher voltage battery of the same mah has more energy stored in it so it has the potential to give more runtime.... or more power, depending on the setup.

Are you more confused now????

You're absolutely correct.. :)

no i think i understand:027:
what runtimes would i be expecting with the amount of cells i mentioned in the previous post? im trying to work out the best amount of cells for me to run

does anyone here know about B4 gearing?
i have a peak dyanasty 19t spec motor?
and a orbital pro BB 2R 12t?
and what would i run for the mambamaxx

anyone?
