Topic: anyone use NP1 - 12volt batteries?

NP1 batteries are what all the pro field guys use anyone use them for there rig?

My dealer recommended using an NP1 to externally power my SD722.  Looks great on paper except the price of batteries, and more so chargers, is pretty high.

I have 5 of them. 4 are 13.2 V NiMH and 1 is the 12 V NiCAD. I bought the 12v NiCAD locally (it's all they had) and turns out my charger won't take them. One of the downsides to NP-1 batteries is you have to have the right combination of batteries and chargers. The nice thing about them is I can fully recharge my batteries in less than 30 minutes.  The bad thing is the price. The NiMH are around $120 each.

If anybody wants the 12v NiCAD drop me a line these run around $75.00 retail, and this one hasn't been used, so I'll make you a deal on it.

You'll have to tell me how well they hold up. The 13.5 volt NiMH batteries I have are only 3.4 Amp hours, but they tend to last about 90-100 minutes under load in the Deva. I wonder how well these other batteries are going to hold up under load.

What are you using for a charger?

If you didn't already have the recharger, you might have been better off buying a standard NP-1 charger.

Your right but I also use that same cup to connect the battery in my rig so I needed it anyway
and I already have the charger.
The cheapest dedicated charger I found was about $175

[wbrisette]

So how did those NP-1 batteries work out? I've been tempted, but not enough to dump $35+ on a battery if it isn't going to work well.

I have not used them yet. I got a wally world battery for my UA5.
I have a Sound Devices coming in the mail and a connector from digikey
so that I can use the batterys for that.
