id love to have a couple of external 12v NIMH batts for the 722 just to have backup power and be able to charge my 722 lions on teh road as well w/ outr having AC power, so my question is:
does anyone know how hard/easy it would be to get a couple of the special hirose connectors for the 722 ??? does anyone have info on how to wire it up ???
also, toddr/greatgumbino/anyone else, would ya'll be willing to wire it up for me granted i can get the hirose connectors ???
Thanks in advance,
Bean

I got a hirose from SD but they charged a lot. I think a regular parts house might be cheaper.
You can put a regular 4 pin XLR with the hirose, then use either an SLA or even a car lighter adapter on the other side as a source. with the car adapter you can recharge driving between shows.

i was thinking more along the lines of having rc tamoiy(sp?) connectors on the other end rather than an xlr cause i wanna get a few 12v 4000mah RC batts, SLA's are just too heavy for this lightweight rig ;)
i have 12 x 3000mah NIMH rc batts i am gonna use w/ the v2 when i eventually get one ;) and the rc>3amp fuse>xlr setup leegeddy made me is perfect for the v2 when i get one, its rc end has 3 rc plugs, and i made my 7.2v battery packs in 3's, so i am gonna have 9000mah NIMH battery packs to sue w/ the v3, id liek to do the same w/ the 12v 4000mah ones, so a hirose>2 rc tamoiy ends would be perfedct, that way i could hotswap the rc batts when using the 722 :)
how much did SD charge you??? wonder if the manual says what kind of hirose connector that isd ??

They give the digikey part number in the back of the manual.. With that you can search for less expensive suppliers. They also give the pin outs. They're pretty bitchin' connectors and aren't very expensive for what they are. They're also available in different sizes and numbers of pins for other projects.
Two of the four pins only go to the 722's battery charge circuit. The other two provide operational power to the 722. So you can reduce your potential 12v draw by only wiring the operational circuit and not the charge circuit..

Bean - B&H has some various cables with the hirose connector already wired in, probably don't have them with the RC connector but you could check it out. I know fozzy or some else had mentioned that they bought the dummy cells for cheap on ebay, allowing one to wire up 7.2v cells instead, maybe something to look into.
i've heard they are a bitch to work with too since they are so small, FWIW
-
another solution (and perhaps the easiest) is to cut the cable on the charger and install 4-pin connectors on the two cut ends.

Bean, why use the RC connector ends instead of the standard 4 pin XLR? If you run into trouble with your batteries in the field, you can often borrow a battery already wired with the 4 pin XLR but the other connector is going to be hard to match unless you want to carry a littel pigtail to convert between the two.

i always make backups and i already have 12 x 3000mah NIMH batts :)
