How can less voltage give you more runtime? Someone on here said think of electricity being water in buckets....bad analogy. If an item is designed to run on a certain amount of voltage, it's going to pull power based on how it was designed....regardless as to how many volts you feed it. And according to the bucket man, more run time is achieved well, with todays cells, running for 5 minutes is as easy as 3.14. I thought going to five cells was to control heating issues, not ensure maximum run time. I said it before and I'll say it again, run li-po, gear your car CORRECTLY and chances are great heating issues will be minimized. No one is addressing gear ratios. I have heard of guys running some really low ratios using 7x2 and 6 singles...then wonder why they have malfunctions.

5-cell was always a way to stop BLOWING motors and speedos in both brushed and brushless. With regard to this, it has been successful.

We do pull more amps than before and it's very easy to see. Before with 6-cells and a 7T you would last easily the 5 minutes, now you can't, you need a brushless to last 5 minutes. Given that the capacity of the cells is still the same, we are still using IB 4200s as last year, then the amp draw must have gone up.

The amps go up in the 5 cell applications because to get the speed you want you have to motor up and gear up. A 6 cell or lipo driver can use a slower wind and easier gear ratio and still be overpowered. Bxpitbull has it right.
