I purchased 2 of the Smart Fly heavy duty regulators. These are the ones with 18ga cables and Deans connectors coming in and going out.
On the product page, there is a calculation to determine actual continuous output:
Amps = 12/ (V in - V out)
I am using 2000mah 6V MH batteries. They have a continuous discharge rating of 15amps.
I know the regulators are listed at 5amps continuous and 9amps surge. But if I do the math on my input and output voltage, I am coming up with 8.8 amps continuous. [sm=confused.gif] I'm cornfused.
Now, the batteries aren't REALLY 6V until they are almost dead. I don't run them below 6.1V They come off the charger at 7.4V and are still 7.3V after resting and that first flight of the day. I have the regs set for an output of 5.4V
Amps = 12/ (7.3 - 5.4)
That comes out to about 8.87 amps.
Does that mean these regs will put out 8.8amps continuous in my setup? If that is true, is it because I'm only asking them to do a little bit of work (7.3v down to 5.4V)
instead of asking them to jump 13V down to 5.4?
Do the math as the battery voltage drops and the continuous amperage rating goes up even further.
Amps = 12/ (6.2 - 5.4)
That comes out to about 15 amps.
Thanks for any clarity on this.
