Jack Norflus Posted December 6, 2013 Report Share Posted December 6, 2013 The limiting factor is not how many different things are connected to the battery simultaneously, but the total current draw. The NP-L7s protection kicks in at about 4 amps draw. 4 amps is a lot for most bag setups - I can't imagine adding an extra receiver at the last minute via the d-tap would bring most people even close to 4 amps. If you were using the battery for a different application - other than in a bag - I could potentially see an issue. But I am also guessing idx is marketing this to the bag market.

johnpaul215 Posted December 6, 2013 Report Share Posted December 6, 2013 We can pack in a little less than 100Wh wow! I sometimes use a single 6Ah/90Wh to power my Nomad bag and get about half a day. I would much rather use an IDX super NP-1. The bag was Nomad12, 2 x 411s, 2 SRbs and a TRX900/STA150. I would also love the half sized ones (with some sort of tap) for the QRX (and if I buy a Maxx). I've been using those batteries made for security cameras that somebody suggested a while back. They are fairly ok, but you definitely get what you pay for.

John Blankenship Posted December 7, 2013 Report Share Posted December 7, 2013 Thanks. You just reminded me of a horrible experience I had shooting in Mexico several years ago. LOTD. Quote Link to comment Share on other sites More sharing options...
Nate C Posted December 7, 2013 Report Share Posted December 7, 2013 I have no problem with where the LEDS are at the moment, but I can see the advantage to having them on the top/small side. D-taps would be preferable due to robustness, form factor, compatibility with other users and ease of use. Would most definitely buy a couple 100Wh Np1's and several half size ones. The half size ones would be a blessing for running my receivers. If it had a D-tap, a D-tap fan out cable could power all my receivers eliminating the need for a second cup. Spare space in the bag gets pretty tight at times. Cheers Nate. Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted December 7, 2013 Report Share Posted December 7, 2013 johnpaul what are you using that is 90wh? Oops, sorry. I'm using a B4B v-mount. I originally bought them because the physical dimensions were listed wrong and I thought I could get a 10Ah battery in that size&weight. It was conceivable because I got a raw (shrink wrapped) 10Ah battery from an OEM dealer that easily fit in my PEGZ3. It powered my Fusion and a bunch of wireless. Worked well, but the charger was a pain. I liked the drop and go chargers of IDX, or most other pro camera & sound gear. I also have NP1 cups and sometimes will use an NP-L7S for the Nomad and one for the wireless. I never had weird power/noise issues running everything off a single battery, so I split them purely for run times. Quote Link to comment Share on other sites More sharing options...
Jason A Posted December 7, 2013 Report Share Posted December 7, 2013 +1 for half size. I've been debating switching to Audioroot for just this reason. Would love to stick with IDX. Quote Link to comment Share on other sites More sharing options...
studiomprd Posted December 7, 2013 Report Share Posted December 7, 2013 " an increase in Watt-hour capacity, " being limited in form factor, significant increases in capacity may be a challenge... ~90WH is, apparently, about the max, and of course the price will reflect... " If it's half size, then it would be half of what a full size one is. " well, approximately, but there is some circuitry in there, too... I, too, like the 5 LED on the (butt) edge that I consider the rear end of an inserted battery... and the recessed nature and ruggedness of D-tap makes that my choice...

fieldmixer Posted December 8, 2013 Report Share Posted December 8, 2013 This is pretty great news. +1 to all of this. I WILL purchase a pair of half size np-1's for powering rx900's when need be, and also utilize in a mini bag setup. A pair of full size 100watthr units will surely find their way in my kit upon release also. Quote Link to comment Share on other sites More sharing options...
fieldmixer Posted December 8, 2013 Report Share Posted December 8, 2013 Regarding the possibility of a newly designed charger, if that is indeed being considered, my wish list would be a simultaneous charge four bay, small footprint, hopefully not terribly too much larger than the two bay available now. A charger like this with four new batteries would be a killer package! Also, personally, a super addition would be, a rubber type bumper that surrounds the corners of the charger. I've have had bumps and knocks to my units I'm convinced contributed to failures and rattling of bits inside. I'm constantly on the road, and a form factor design that is road friendly is like gold. Lastly, is the interest and or technology available to manufacture a single Np1 charger possible. Something real small similar in size to a power cup say? The reason I ask is, that would make a wonderful emergency back up unit that you could take everywhere. Is this were a IDX kick starter I would contribute.

johnpaul215 Posted December 8, 2013 Report Share Posted December 8, 2013 IDX batteries seem to have secret circuits, but other brands sometimes have a wall wart to d-tap or DC plug trickle charger too (sometimes aka travel charger). Quote Link to comment Share on other sites More sharing options...
taylormadeaudio Posted December 8, 2013 Report Share Posted December 8, 2013 I've been lurking around this thread since it was started... wasn't planning on posting, but thought the fine folks at IDX would appreciate any and all feedback from their customers, so FWIW... I use several DC systems, both on my cart and in various bag rigs. I couldn't be happier with the NP-L7S design. I use the RA NP1 Cup and BDS systems on my bags... the Cup fits perfectly in the Petrol side-pocket attachment, which makes for effortless deployment and monitoring of batteries... I have several NP's that I purchased mid-'06 that are still working flawlessly (they don't last quite as long as the newer units, but...) I normally track consumption through my rx's and recorders, so wouldn't have much use/need for additional metering... or half-sized batts. In short, keep it simple (less to go wrong)... focus on improved capacity... just keep doing what you're doing... if it ain't broken... ~tt Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted December 8, 2013 Report Share Posted December 8, 2013 BTW would the higher capacity and/or half sized batteries still work with our current JL2plus chargers? Quote Link to comment Share on other sites More sharing options...
dominiquegreffard Posted December 9, 2013 Report Share Posted December 9, 2013 I also think that a single idx np1 compact charger would be great addition to my kit Quote Link to comment Share on other sites More sharing options...
Mark Orusa Posted December 9, 2013 Report Share Posted December 9, 2013 I'll echo many of the thoughts shared already: Higher capacity full-size NP, awesome 1/2 size NP, awesome D-tap power take-off, bonus 4 bay simultaneous charger, awesome I use the LEDs to see if the battery is used or full, so three is good enough for me, but 5 would be a bonus. Same quality we've come to appreciate and rely on. I have the KL-4 4-bay simultaneous charger and while it's nice to be able to charge four batteries at once, it literally takes 16 hours to do so. Apparently the more batteries I put on it, the slower the charging. It's much faster to use two JL-2Plus chargers. If you can make a four-bay charger charge all four batteries just as fast as the JL-2Plus charges one, I'll be sold. I think this is a pretty common way of mounting the NP for us sound mixers: Thanks for listening, Mark O. Quote Link to comment Share on other sites More sharing options...
pkautzsch Posted December 9, 2013 Report Share Posted December 9, 2013 a rubber type bumper that surrounds the corners. I've have had bumps and knocks to my units... +1. It could double to protect the contacts from shorting. I might use a D-tap connector for quickly powering additional devices without having to dive into the depths of my bag. So it would best be placed right round the corner from the butt end, as I have the battery "contacts down - butt end up". Quote Link to comment Share on other sites More sharing options...
IDX TEK Posted December 9, 2013 Author Report Share Posted December 9, 2013 BTW would the higher capacity and/or half sized batteries still work with our current JL2plus chargers?

Tom Posted December 11, 2013 Report Share Posted December 11, 2013 D-tap connector on top of the 100Wh NP-1 and LED power status indicator on left or right narrower side sounds very yumi..... Quote Link to comment Share on other sites More sharing options...
Richard Thomas Posted December 11, 2013 Report Share Posted December 11, 2013 If you hit 100Whr it starts having flight carry on implications (batteries need to be declared and only a limited number can be carried). I use the hawk-woods half size 35W batteries already, so some competition there would be good, especially if you could squeeze in a bit more capacity Fieldmixer, speaking of 'travel chargers', I put this together a while back, audioroot sell the charger on eBay and I just soldered on a female inline hirose connector. It's been working fine for over 6 months now: http://rtsound.net/?p=315 Quote Link to comment Share on other sites More sharing options...
IDX TEK Posted December 12, 2013 Author Report Share Posted December 12, 2013 If you hit 100Whr it starts having flight carry on implications (batteries need to be declared and only a limited number can be carried). You are correct on the transport limitations on batteries over 100Wh. To maintain the NP1 form factor, we would have to keep the pack just under 100Wh; so no transport issues there Quote Link to comment Share on other sites More sharing options...
fieldmixer Posted December 12, 2013 Report Share Posted December 12, 2013 Some camera batteries "click split" in two, to adhere to the regulations. If flight regulations were of no consequence, how much could fit in the np1 form factor? Quote Link to comment Share on other sites More sharing options...

johnpaul215 Posted December 12, 2013 Report Share Posted December 12, 2013 This is the side by side of an NP-L7s and the v-mount I'm using. I will happily eBay my 3 v-mounts and charger if/when I get my hands on this new IDX battery (it'll have the same capacity). Quote Link to comment Share on other sites More sharing options...

John Blankenship Posted December 13, 2013 Report Share Posted December 13, 2013 The problem with printing the info on the battery is that it could change. I know at one time IDX had a conformity letter on their web site that you could print out and carry with the batteries. That may still be the case, but I haven't checked for a while.
