Brian Rose Posted August 1, 2005 Share Posted August 1, 2005 Hello All, I'm shopping at bh photo.com for a battery for my Eclair NPR. I'm not too familiar with the types of batteries and power, but there was a battery belt made by Bescor that was 12v with 7 amp hours. Could someone explain what amp hours means? How many mags do you estimate I could shoot with a battery of this strength. If this battery is not a good choice, what would you all recommend? Best, BR Link to comment Share on other sites More sharing options...
andrewbuchanan Posted August 1, 2005 Share Posted August 1, 2005 More amp hours = more run time. Amp hours are some equation of how many volts the battery can run at over a certain period of hours. Get a BIG battery, the biggest you can find. Driving a motor with a 400' film load is a lot bigger job than spinning a DV tape. Also, these are not lith-ion batteries like camcorders. So get a big one if you plan on running the camera for more than 1 or 2 mags at a time. My kit is 2 of the biggest 12V Bescors and one little one (so I can finish what I am doing when the two big ones cash out). Also, when you get one, be sure to include time to charge. Most of these take 16 - 20 hours to get a full charge. Link to comment Share on other sites More sharing options...
Brian Rose Posted August 1, 2005 Author Share Posted August 1, 2005 So, how many mags could I get out of a 12 v, 7 amp hour? What size battery would you recommend (In terms of amp hours) Best, BR Link to comment Share on other sites More sharing options...

Can you just use any battery you would use for other Eclair NPR motors? or do I need something specificly for this one? Link to comment Share on other sites More sharing options...
Premium Member Andy Sparaco SOC Posted December 1, 2005 Premium Member Share Posted December 1, 2005 (edited) Power Tool Batteries-Cheap, fast recharge, available everywhere, 12 volts or 14 volts for a little extra umph Long Valley Equipment sells (do google search) a battery holder which is a Dewalt flash light which has been gutted with a lead wire soldered to the terminals in the battery holder. Comes out ending in a 4 pin XLR . Pin 1 is ground Pin 4 is hot. Just check the polarity with a volt meter. Simple, elegant, cheap, indestructible and you can use the batteries for power tools Edited December 1, 2005 by asparaco Link to comment Share on other sites More sharing options...
