Sony L type/NP-F Battery Extenders

[Cvetko]

Hi,

can anyone point me to the right direction with this idea: I am searching for an Sony L type/NP-F battery "extension cable," featuring a smaller form factor dummy NP-F battery on one side with a ~40 cm cable connected to an NP-F plate on the other side providing pass-trough/unregulated power. 

I jumped on an opportunity to build a lower cost Sound Devices 633 bag kit in an Orca OR-30 bag. Harvesting power off of an enviable collection of NP-F970 of mine by using the two terminals on the back of the 633 means the recorder can run for 12+ hours easily, but gets bulky and does not fit as nice into the bag. So I wanted to move the large batteries into another compartment via an "extension cable".
It woudl be great if output from the dummy batteries remains unregulated (unlike what many NP-F plate offer) so the voltage reading reamins accurate on the recorder.

Yes, yes, a BDS with 2045-styled batteris would be the an by-the-book solution, but also keep a larger hole in the accountant's books. Unless any of the members is willing to aprt with a battery kit in Europe ... 

Anyway, any suggestions?

Probably just get something like this. So you can power your receivers as well:

What about one of these

they do a single battery version too.

I already have one Hawk-Woods' DV-SQN2S plate. Now I need to find a dummy NP-F battery that outputs a "direct voltage" (unlike their LR-05 that has a 8,4V regulator). Any suggestions?

The Kortwich option also seems to be regulated to 12V, but looks nicely priced.

You could

- ask Kortwich for a special order without regulator (and expensive HR10 connectors)

- do an image search for "NP-F" "Adapter" on google and aliexpress and find yourself in a rabbit hole of ready to use products and DIY components.
