Light Cannon and Rechargeables

[Overboard]

I need help from one of you smart guys!

I am trying to estimate the available burn time for the UK Light Cannon and 4500 Mah Rech. C cells.

The Light Cannon is 10 watts (but HID, any issue here?) and I want to only take the batteries down 80% of capacity. If my math is correct, wouldn't that be an available burn time of about 3.4 hours?

Thanks,

Mark

I get about 3.5 hours out of my 4500mH Rechargeables for my Light Cannon. Bets buying new batteries every weekend!

dont you just do a burn test with whatever batteries you are going to use, that will tell you.
