Hi Tony,
I am in the process of upgrading a simple foam trainer from stock powertrain to a more powerful setup but have run into a specification question for which I need and solution.
Using your very helpful method of selecting a Motor, ESC and battery, there are certain parameters required for all the calculations.
All up weight carrying a 2.2 3cell battery is 1600gr
The motor that I will probably settle on is a 905KVA but I can only find a Max current rating of 18Amp in available specifications.
I want to determine Cont. and Max Watts for this motor for which I believe I require Battery Volts and Motor Amps to do the calculation.
Question: The 2.2 3Cell battery is rated at 11.1V but as far as I know, this means that “Volts under continuous load” is +-9.91V and “load under Max load for limited time” is 9.69V
Which of these Volt values do I use to calculate Motor Continuous Watts (W) = volts x amps?
Ultimately, I also want to calculate the theoretical Watt/Pound Ratio.
Thanks in advance
