Well, I just picked up the first parts to put together a little SLA pack to power my AD-20 and PB224. I stopped by a little broadcast supply shop here in Dallas to pick up some T-160 SVHS tapes for my ADAT, and low and behold... they were a PowerSonic dealer.
I ended up with a neat little 1.2AH SLA ($16) and a PowerSonic charger ($34). I'm just laying it all out and getting ready to order my connectors. It seems like the standard is 4-pin XLR, and that would certainly work. It fits all the apparent needs:
- Can't short during connect/disconnect
- Can't be plugged in to anything else
- Is easy to connect/disconnect
But it seems like an awfully large connector. Does anyone have any comments about the 4-pin XLR versus the Mini-XLR as a power cord?
I guess the Mini-XLR could be misconnected, but I don't currently have one in my rig. And I suppose if I upgraded, I'd need a different battery/harness anyway.

Just as with full size XLRs, the mini-XLRs can only be plugged in one way. If you want to keep everything nice and small, go ahead and use the mini-XLRs - you can always swap out to a full size 4-pin XLR later if you want to.

I go with the 4-pin XLR simply because that's what everyone else is running. I can think of times where I've needed power from someone or needed to give someone power from my batts at a show. In every case, both of us ended up with tapes because our gear was standardized on the 4pin XLR connectors.

I know this is a really old post, but it's still relevant and I hate to start a new thread on this.
Is there a standard wiring format for power connectors? I've just ordered some 4 pin xlr connectors from mouser.com. I see here that people are using the mini-xlr's . How do you swap power with someone unless they are pinned out the same? Did you just get lucky or was there a standard pin-out?
I.e. Pin1= ?
Pin 2= ?
Pin 3= ?
Pin 4= ?

Indeed there is. I don't have it in front of me at the moment, but I do remember that it's different for 6v and 12v -- at least the + side, so you don't have to worry about plugging into the wrong voltage.
If someone doesn't beat me to it, I'll look it up.

Thank you. What's the 6V for?

Thank you. What's the 6V for?
lot's of gear runs on 6V. other gear runs on 12V.
For example, I currently run my Sony D8 and my Lunatec V3 from 6V SLA batteries. with this standard pin layout, if I accidently plug in my Sony D8 power cable into a 12V battery, I won't fry my deck, because nothing would be connected. (different pins are hot).
if you're making a cable for 12V gear, just ingore the 6V pins, and leave pins 2 & 3 empty.

what about in between voltage? Ie 9 and 7, is there a standeard pin assignment?

I'm faced with the same question, what to do with the +5V for a JB3. The problem is, there's not enough pins on these 4 pin xlr's (especially with 2 GND's)
Based on this thread, I'll wire all my batteries with a female xlr with GND and +12VDC.
Then I'll make a power cable with a 5V regulator in line to knock the 12V down to 5 for the JB3.

Heh...definitely an issue. I don't know of other standards. Best way to handle these cases is to label everything clearly, at least voltage and pin assignments.
