Topic: Tascam HD-P2 power - 9v li-ion?

[AlexG]

Wading through the Team Tascam HD-P2 threads revealed the following two people successfully using 9v batteries to power the P2.  Alex, Terry - can you chime in and confirm you're powering your P2s successfully with 9v and that you're using the stock DC power input?

Thanks for the info, now how's about the best place to get an external battery situation going.
I like the idea of running an external & having the 8 AA's as backup.

My 9v DVD battery from radio shack works great too and even the cable and adapters it came with worked with it out of the box.

But so far I've been using the 9v WalMart battery...

Yep it works great.  It's nice to have the same battery for both my UA-5 and HD-P2 def makes things easy.  I was even at Rat Shack today getting new adaptaplug stuff for my HD-P2.  The cable included with the battery works but it's a tad loose.  If you plan on making you own rs adaptaplug for it here are the rs part numbers

F to F Adaptaplug Cable #273-1740
Adaptaplug M #273-1716
Adaptaplug B #273-1705

+T Alex for the part numbers, nice!

just got a 12v and 13.2 (switchable) bike battery which is a lithium-ion.  i have wired the end to an XLR connection and then to a 'y' XLR splitter, to power the hd-p2 and the mini-me.  we've even got another splitter to run into the m248, but rarely need it that badly. 

anyways, it is a small 5.2maH lithium ion.  bright blue light, waterproof housing, and a nice locking cable to splice to.
from batteryspace.com, good deal.

it ran my rig at RE:Generation for 6hrs, on one charge. i ran it on 13.2v mistakenly so i think i drained the power quicker than normal.  i'm gonna try 12v for 7hrs this weekend.

Even though people are running 9v external power just fine, thought some might want to see the official word back from Tascam:  basically, "try it and see".

After looking into this issue and sending out a couple of E-Mails to
engineering; and getting the standard safe answers back, (i.e. "It
looks like it should", "I don't Know", "try it and see"), I think that the
answer is probably yes to all your questions. As near as I can see it,
the circuit schematics all appear to support your conclusions in this
matter. I can't see any reason why your particular senarios would not
work just fine. The only question that arises in my mind is whether or
not the 9volts from the li-ion battery will last long enough before it
falls below the operational threshold. I'm afraid you will have to take
my colleague's advice and try it and see.

Thanks for your interest in Tascam.

i dont think a 9V is a good idea, and those that do - one question.  why push the limits of what you can power, it seems like under-powering the unit regularly would lead to more electric breakdown.  any thoughts on this?

Ive heard of issues when you overpower something but very little on underpowering causing issues down the road.
I don't know much about EE and stuff I'm a hack to say the least. Yet in my experience it's either going to power and do everything it is suppose to do or it's not going to power up.
a 9v li-on is pretty much the same as running 6AA's internally from the math I have seen. Or am I wrong on that? A 9v li-on as it discharges I don't think goes any lower than 8.6? or something like that iirc
Wouldn't that be in line with normal AA alkalines? I do think it is more tolerant of voltages than the JB3 was.
I have left my P2 running for at least 12 hours on a lion just sitting there powered up; as well as using the 9v's the entire life of owning the P2. So I guess I'll find the answer out down the road one way or another.

Good question still.

I've tried the Toyo SLA with my P2 which just crapped out on me yesterday. Bummer. I really didn't like it because I couldn't tell how much life was left in it. There were no led's. Of these two, which would you suggest I go with?

Or is there another that I'm missing. I'm not all that handy, so a battery that I have to solder parts on is not one for me.

Or this one seems like it would give you ~12hours and ~20 hours for the 130wh unit. Anyone using either one of these with their P2's?

Want one really bad, but can't justify $200 on a battery...  The 12v SLA solution works for me and is a lot cheaper...
