I'm having a total brainfart this afternoon, and can't remember how to calculate runtime for a boost driver situation.
Can someone show me the math?
If you want to use my numbers:
6 XP-G2 in series - vf= 19.2v
driver running 1.5A
assume for now battery is 11.1v, 2200mah.
I'm seeing output power as 28.8watts, (19.2vf*1.5A=28.8W)
Input power is Output/efficiency - we'll assume 90%, so 28.8/.90=32W.
this is where I get stuck, and don't know the next step to convert it into a runtime guesstimate.
any help is appreciated.
