Tri-Flash Update

I just thought I’d post a quick update on my tri-flash setup, since I just took delivery of three high-voltage battery packs for the three 540EZ strobes I use in the setup. So, using a bit of duct-tape (or duck-tape, depending on where you’re from), I strapped ’em onto the light stand and hooked ’em up.


Of course, that needs a lot of batteries, so I sourced some bulk 3000 mAh NiMh batteries from eBay for about €25:


So, that now gives me about 400Ws of power when the three strobes are set to full power, and a recycle time of about 2.5 seconds. And when I drop the power to 1/8 on each strobe, they can keep up with continuous shooting mode of 3.9 frames/sec on my 5D MkII. Kewl, eh? 😉



The eBay batteries turned out to be total garbage. Compared them to some Aldi 2300 mAh. Aldi batteries were able to drive a 1.2W bulb at 500mA for over 3 hours. The “3000” mAh eBay batteries lasted just over an hour. So the 3000 mAh rating is a deception. They’re waaaaay down on that, closer to 800mAh! I’ll be in contact with the eBay seller as soon as I’ve got the graphs done of comparisons against a couple of brands of 2300 mAh batteries. Yes, I’m a nerd.
