haifai Posted March 29, 2017 Report Share Posted March 29, 2017 So here we go... DC solution for my small audio bag, powering SD 744T and Audio Development AD071. Sony NP F and RRC 2054 compared: Charger: Battery cable, you got 2x DC (red and black wires) and 3 wires for the smart data (you dont need to use them if you dont want to add a control display). I ordered two as they are cheap for experimentation. For one of the battery cables i made a little "breakbox", one black and one red wire connected direct to hirose 4pin, one black and red wire connected to a variable DC/DC voltage regulator - the one i used is a lot oversized, i took what i had laying round here (this one was 5€ new), a simple step down converter for a few bucks should be good enough. The regulated output can be switched off to keep it out off the circuit when not in use. the cables for the smart bus data are not used, i gonna replace the DC/DC converter with something smaller later and put a connector with the 3 smart bus wires at the case, maybe one day i feel like adding a control display to the set... with the second battery cable i gonna make a more simple solution, at my first test i remarked that i really dont need a step down conversion... when i tried to use my ad071 mixer last time with a fully charged NP 1 battery it refused to work, it was O.K. only with a not fully charged NP1... Strangely enough with the fully charged RRC Battery the mixer is working without problems, so i gonna put a simple 7pin neutrik xlr connector direct at the second cable and make a simple snake (split cable from a neutrik 7pin to 2x Hirose 4pin male for DC and 1 Hirose 4pin female for the smbus data if one day i feel like connecting a control display. At least one image of my old "breakfast lunchbox solution" to give "eye cancer" to the electronic engeneers in this forum ;-) That has worked the last year for powering just my AD071 mixer flawlessly... Its working up to 5h (depending the mics attatched, 2 channels phantom power activated). I am not an electronic engeneer, so my soldering skills are limited... Shurely there are professional guys that are able to do better but i am happy with my homebrew solution... regards karsten Quote Link to comment Share on other sites More sharing options...
soundchris Posted March 29, 2017 Report Share Posted March 29, 2017 Hi Karsten, I am using something like this with my lipos. Does not need extra power, shows single cells and overall voltage.. Quote Link to comment Share on other sites More sharing options...

soundchris Posted March 29, 2017 Report Share Posted March 29, 2017 10€ from ebay.de http://www.ebay.de/itm/LiPo-Tester-V2-Battery-Batterie-Kapazitat-Capacity-Checker-1-7s-Li-Ion-NiMH-Nicd-/262608741366?hash=item3d24b363f6:g:SusAAOSw9IpXy6EN Quote Link to comment Share on other sites More sharing options...
haifai Posted March 29, 2017 Author Report Share Posted March 29, 2017 thats a lot cheaper than the 150€ rrc display... for the moment i am happy with the displayed voltage at my 744t, but when i do some soldering next time this little funny box is worth trying...

OPS Posted August 6, 2017 Report Share Posted August 6, 2017 Hello Karsten, Inspired by your idea I have a box with integrated battery-slot. Hirose are with 2.5A resetable fuses on each output and one is in the loop. The 3 smart bus wires give more information than the "capacity controller". I have heard that an Arduino can read the information and put it on a display. I will be looking for more information. Quote Link to comment Share on other sites More sharing options...
MarkC Posted August 6, 2017 Report Share Posted August 6, 2017 I like the look of that! Quote Link to comment Share on other sites More sharing options...
OPS Posted January 24, 2018 Report Share Posted January 24, 2018 This is my new design. I tried to make it as flat as possible. So it fits perfectly in every pocket. Each output can be switched separately and is provided with fuses. Of course there is also a main switch. The outputs are all led down. the smart battery is connected to the Distributon Box via Hirose and can be stored anywhere in the bag.

Andrew From Deity Posted March 6, 2018 Report Share Posted March 6, 2018 For $30 you can own these 75wh 12.6V batteries and skip the idea of a docking cup. You can also charge these batteries as you draw power from them. This way you can plug in your bag while your using it and run your bag off wall power and without chaining anything just unplug and your running off battery without losing power at all. https://wavreport.com/2017/11/29/batteries-part-2-diy-modding-the-talentcell-12v-lithium-battery/ Quote Link to comment Share on other sites More sharing options...
mikewest Posted March 6, 2018 Report Share Posted March 6, 2018 I use Turnigy LiPo batteries 4 cell 14 volt I can run a 688 and at least 2 radio receivers/camera link/headphone tx for a normal day mike Quote Link to comment Share on other sites More sharing options...

Thanks I'm pretty sure you can get them straight from Inspired Energy... but I think I grabbed a Remote Audio branded one from a broadcast store here in Sydney. It does the job, but the rubbery cup isn't quite as nice as the Audioroot plastic one. The Audioroot cup clips on and seems a bit firmer.

OPS Posted October 19, 2018 Report Share Posted October 19, 2018 On 10/10/2018 at 2:08 PM, Chris said: RF save? It consists of a fairly thick aluminum housing, so the penetration of RF signals is not possible. Inside, no components are installed that can cause RF interference such as step-up or -down converter or displays Does that answer the question sufficiently?

tilllt Posted February 5, 2022 Report Share Posted February 5, 2022 For future reference, mentioned in the OEM Chargers specs: https://www.texim-europe.com/product/RRC-PMM240-RRC Pin 1: Battery (+) Pin 2: SMBus Clock (SCL) Pin 3: SMBus Data (SDA) Pin 4: ID (T) Identifier Pin 5: Battery (-) Quote Link to comment Share on other sites More sharing options...
Peter Josh Posted October 27, 2023 Report Share Posted October 27, 2023 Also inspired by the very interesting discussions in this forum, I created a small DC power supply distributor for my small bag. This fuse module is designed for power distribution in low voltage system. Protections against: - a short circuit SCP - an overload OLP - a surge (varistors) 2 On-Off locking switches Quote Link to comment Share on other sites More sharing options...
