Hey guys -

I've used a 1x1 Litepanel with those camera battery belts (forgive me, I'm not sure what the official name for that piece of equipment is) but am not sure how long that battery would last if the Litepanels were running at full power. I'll be without power for daytime exteriors (for interview footage) and wanted to know how many I should have on hand.

Any thoughts? Thanks!

1'x1' litepanels draw 37 watts @ 24vdc or 45w @12vdc, so thats 1.54 and 3.75a respectivly. That is what the battery needs to supply per hour, call amp hours or ah. You might want to add 10 to 20 percent to the above numbers, as batteries age, their storage capacity decreases.

This battery belt:

supplies 12vdc 14.4 amp hours, should run the 1x1 panel for approximately 3 hours and 12 minutes. 14.4ah / 4.5a = 3.2 hours
