  1. I thought I'd share my opinions on this lightweight battery I came across. Introduction: This is a mini V-lock battery called the FXLion Nano One. It has D-tap, USB-A and USB-C for powering various devices. It's very flexible as it can be charged in a standard V-lock charger, via D-tap, AND USB! So I recently upgraded from the MixPre-6 to a MixPre-10 II and needed a "real" battery instead of a USB power bank. Since I have various video gear anyway, I wanted something I could throw on a LED-light if needed etc. Performance: I tested an "average" use case on the MixPre-10, recording
  2. After an outcry from iPhone users that Apple is slowing down older iPhones to prolong battery life, the Verge is reporting: Apple says that batteries are “consumable components,” and is offering anyone with an iPhone 6 or later a battery replacement for $29 starting in late January through December 2018 — a discount of $50 from the usual replacement cost. Apple’s also promising to add features to iOS that provide more information about the battery health in early 2018, so that users are aware of when their batteries are no longer capable of supporting maximum phone performance.
  3. Hi! I have three wireless systems from Audio Limited Envoy series that supports external powering. The thing is that two of the recievers are CXIR and supports power between 7-18 volts, and one MXIR that only supports 7-12 volts. The current draw is 55-150mah from the recievers. I am looking for a solution to externally power all the three from one battery. I have looked at some NP style 11.1 volt batteries, as well as Li-on batterys such as the Inspired Energy ones. I've also looked at the 14.4 volts NP style batteries, but then I have to step down the 14.4 volts to 12
  4. I have been wanting to build an external battery to use with my Zaxcom bag rig consisting of a Nomad 10 and Zax wires (QrX200 and 2 TRX's) for days when I am not needing to carry the bag and I can use my small cart. I'd like to keep in a small pelican type case and I am thinking along the lines of making it so I can power to my BDS so it would be a fast switch over from my bag batteries. I've been doing my own research around and trying to figure out the right setup when it comes to voltage, watts, amps, etc. I am a complete amateur at this so please forgive my ignorance. Like I said I have d
  5. I'm just curious if folks have seen a marked improvement in battery life on the 744T when an SSD was used. Thanks, Michael http://rabbitearsaudio.com
  6. Seeking user feedback about these models. Remote audio claims they are lighter than competition, but I have yet to find specs online. Are users pairing these with Meon's, using them stand-alone, or coupling with regulators? Thanks
  7. Hi, Has anyone had any experience using portable car jump starter power bank’s as an external battery for their location sound equipment? I’m looking for a budget external battery for my basic boom and lav kit and have come across these. It seems to have a good capacity, output’s 12v, fairly light weight and be very affordable compared to NP1 solutions. Or am I missing something? Here are some example’s of the product: http://www.ebay.com/itm/68800mAh-4USB-Multi-Function-Car-Jump-Starter-Power-Bank-Rechargable-Battery-12V-/371500798517?hash=item567f2c5235:g:AYoAAOSw2GlXKWrt
  8. Hi! Im planning to solder a 4 pin Hirose connector to the negative and positive wires of this battery holder, planning to make this a "just in case" spare battery if i run out of NP1 during a shoot. Id like to know if, coz i dont have a 4 pin hirose connector yet, which one will be the positive side of that and which one will be the negative in the hirose? Or will it just any side? Attached to this post is the battery holder that im saying. Thank you so much.
  9. I recently dropped and NP1 on a shoot, and found a crack on the shell that exposes a bit of the battery near the connections. For now, I've carefully super glued the thing together, but I know that wont last. Is it possible for me to just buy another NP1 plastic shell to re-house the battery? Is that even possible to swap it?
  10. First outing yesterday for my little remote switch and battery distribution system that I cobbled together from bits I've had lying around for a year or two. The remote switch and voltage display clips neatly into a Petrol pouch and the wiring runs into the bag to my Tracer LiPo 10Ah battery and a simple, fused four-way Hirose distribution box. (I found the blue Deltron box on Ebay as part of a set of five for £10 - I'm keeping a couple of the others, but in anyone in the UK wants one or both of the remaining two for a couple of quid, let me know.) Battery input to the remote switch is via a 4
  11. The 4 hour battery life on the SSM was the drawback that kept being repeated (politely) in threads and posts. We found a different battery that is 10 thousandths thicker but has 40% more capacity. At the same time, we added a new power supply chip that can run both buck and boost. So it can provide 3.3 Volts whether the battery is a fresh charged 4.2 Volts or nearly run down at 3 Volts. Note that one voltage case is higher than the desired output of 3.3 Volts and the other case is below. Hence a buck and boost power supply. That additional range gives us about another 10% of battery life. All

  13. Hello Chaps Im in need of a tutorial on how to change my internal AA battery in my 702T machine. Ive never attempted it before and wanted to research the procedure first. Are there any youtube or videos on JW that show this procedure ? Im led to believe that its not a complex task and that why Im feeling bold enough to open the machine myself. Many thanks Greg Albert #fromsouthafrica
  14. The DuoPack is now in stock at Lectro. Accepts SR/SR5P Series slot receivers Dual 3.7V Li-Poly 3000mAh batteries Up to 17 hours operating time per charge Built-in recharging circuitry Dual, balanced audio outputs The DUOPACK adds a rechargeable battery pack to an SR Series receiver, allowing it to operate as a stand-alone device, further expanding the versatility of this product family. Two lithium-polymer flat battery packs, one on each side of the assembly, provide enough capacity to operate the receiver for up to 17 hours per charge. The control and connector panel includes audio and pow
  15. Another thread was talking about lithium ion batteries and overheating. This example wasn't meant to perform a test on the batteries but is what happens when you misread centigrade for Fahrenheit on your temperature chamber. You get two very distorted batteries and singed fingers. One of the engineers Monday, misread the readout while testing two devices at 140 degrees. He didn't realize the error until he picked up the devices and scorched some finger tips. 140 C of course is 284 F. To widespread surprise, the units still worked and so did the batteries, though now they don't fit in the bat
  16. Hey Everyone, Just want to hear your opinion on a few things: 1. What is the best position for the LED power status indicator on a NP battery? 2. If a DC power connector was available, what type and where would you like it (D-Tap or Hirose, left/right side, top, etc.)? Thanks! -Zack
  17. Hi I´ve been testing Np 1 Lithium Li-ion Ultimate NPLU-84. 14.8 V 84 Wh from Pink Noise. New battery and fully charge with my old IDX KL-4 charger. The test was Sound Devices 664 with 2 mic. phantom power ( Schoeps MK 41 and Sennheiser MKH 70). And power for two Audio Limit 2040. At 8.15 AM I arm four tracks and hit the recorder button . I was recording constantly and stop for lunch12.30 PM where I power down the lot. At 13.10 PM I power up everything and was recording again constantly. At 17:00 PM I have my first warning for low power. I keep on recording and at 18.20 the SD 66
  18. Announcing new Remote Audio NP-1 battery cups with improved back plate design. Remote Audio is now implementing a new back plate design on all of its NP-1 battery cup products. The new back plate is made of ABS plastic and custom molded to fit our NP-1 cups. It affixes to the cup with self-tapping screws and is designed to be a permanent replacement to the previous adhesive back plate. If you have an existing back plate that is peeling or needs repair, we are offering new back plates at no charge for a limited time. You have the following options: 1) You may send your peeling N
  19. I thought I'd start a new thread so it would be easy to find and be more easily searchable. So far the Quantum alkaline AA's are looking very good; 2.2 Ah for the Quantum versus 1.2 Ah for a Panasonic AA at a heavy drain (SM transmitter) of 400 mAh. That's an 83% improvement. (!) The second run is at 500 mAh and I got 2 Ah. This is an SM drain toward the end of the battery life. Pretty impressive. I still have to run the Panasonic at 500 mAh but it will probably only make 1 Ah. Adding to my original post, the Panasonic at 500 mAh made 1.1 Ah while the Quantum made 2.0 Ah for an 82% adv
  20. Okay, so I just wanted to through this out there to see that you all though. I have been looking for a good and less expensive than the NP-1 route to power the gear in my bag and have though of something interesting. But before I go trying something dumb and breaking my new toys, I thought Id post all about it here and see what you guys came back with. So here we go: One of my deepest passions in life has always been photography and pretty much all areas of it at that. The area in particular that got me thinking was that of on location portraiture. Specifically the power sources photograph
  21. <p>Hello all,</p> <p>&nbsp;</p> <p>I'm making a minimal-pack trip to the USA and have been looking for an alternative to the usual NP-1 suspects with regard to batteries. I've come across a company called Tracer</p> <p>(<a href="http://www.deben.com/tracer-battery-packs.html">http://www.deben.com/tracer-battery-packs.html</a>) which makes LiPo packs for the hunting community and at a reasonable price, 8AH/12v for around US$160, which seems like a good deal. I'm just wondering of anyone has any experience of using this type of battery
  22. What do you all do with your spent disposable batteries at the end of the day? I have a number of Powerex 2700 that I primarily use, but inevitably disposables come into play now and then. I know there are laws, certainly in CA, that mandate they be recycled. I've been just tossing them in the bottom of one of my cases and forgetting about them. So, today I finally re-organized my gear and half filled a shoe box with dead AA's I'll be looking for a place in NYC to drop them off, but was wondering what you all do with yours
  23. Hi everyone I have been in the look for a new mixer for the cart. I have been using a rental CL-9 and was thinking on buying one. But i hate the fact that i have to loose an iso for a talkback mic. So i'm thinking that if i'm going to loose an iso, at least i should gain better preamps and outputs, so i'm looking into an external mixer, like a cooper or audio developments. But i have seen a lot of people using the yamaha 01v96, or sonosax or similar. I would love the extra channels and outputs and all, but i'm just wondering, how do you power it on the cart? They only accept 120-240v, so do
  24. Dear community, I would like to make a simple "T" power supply for my old 416T, intended to be used on a wireless boom. I don't want to use a barrel style adapter, as that kind of adapter eats up lots of power just to convert the P48 to T12, and I don't want to be changing batteries on a plug-on TX every hour. Plus, using external power would allow me to use basically any TX. I already have a lightweight 12V Li-Ion rechargeable (which actually gave me the idea for that project), so that's no problem. However I can't find any reliable diagrams on the web, they all show the 180 Ohms resistors
  25. Would it be possible to add the voltage display to the main screen of your 411 receivers instead of the 'battery meter'? I find that number to be way more useful. Thanks.
