DC powering solution small audio bag

10 posts in this topic

Hello everybody,

i am looking for a smart solution to power my small audiobag with a 744t and a audio development AD071 premixer.

i prefer to keep it light as i do a lot of documentaries and have to be mobil...

The oportunities i am thinking of right now is either to use a Sony NP F970 with a step up converter to have 12v for recorder and mixer or to do a DIY

(... I am not afraid of soldering ;-) ) powering solution based at rrc smbus batteries:

or

http://www.rrc-ps.com/en/products/battery-packs/standard-smart-battery-packs/rrc2054/features.html

(that one is used by sonosax for the new r4 recorder)

is there someone how has experience with both power systems (esmart vs sony np-f970)?

pros and cons, runtime, weight...

Thanx,

Karsten

I made my own battery solution with the Sony batteries but instead of a step up converter I just use 2 batteries connected in series. It has been working fine for me for 6 months now, annoying to have to use 2 batteries together but seems fine

If you are handy - buy a couple of the Remote Audio (Inspired Energy) battery packs (49 or 98wh) and solder up a pigtail with all of the connections that you need.  Not the prettiest, but definitely the least expensive option and lightweight.

I do prefer my BP-U60 batteries for their battery check lights, than the NPF970 batteries I have.

I would avoid stepping up the voltage. It's not the most energy effecient option and you won't have any means to monitor your battery's voltage, i.e. you won't know when it dies. Use two as suggested above, or one of the other optins mentioned

hm, two np f970 its not an option for me, the ad071 mixer is not running with more then 15v...

maybe best solution will be a rrc2040 -12volt should be good for 744t and ad071, seems reasonable priced and should be fun to build

a powering system with the smbus reader...

If course, that might be a good option.
I have a HawkWoods adapter with two np-f type batteries (doesn't have to be the 970, you can use smaller ones). It provides 4 Hirose outputs which are regulated at 12V, so good for your AD mixer. And then you have one flying lead unregulated which you can use with the 744 and it will show you the battery depletion status. Not as exciting perhaps as an SMBus setup, but for me it's all the info I ever wanted, easily available, fairly cheap, and the batteries can be replaced easily in an emergency

I use Turnigy LiPo model batteries ($60)

4 cell 14.4 volts and can run a 664 and other stuff for a day!

Mike, how do you charge the battery? What is the capacity you are using? 10Ah?
