A couple months ago I got some Studio lights and I want to use them around town without having to plug them in. I know nothing about the battery packs, so could somebody point me in the direction of some good ones and some cheap ones? Are they universal or brand specific? If they are I'm using...
Nikon N90s w/grip
Sigma 15mm Fisheye
Nikon SB-600 x 2
Radio Slaves (One Sender, two recievers)
Impact Studio Lights x 2
Lowepro Nova 4 AW shoulder bag (for photojournalism)
And too many accessories to list
That's about it for...
