Hello everyone,
So I've been trying to find the perfect method for dumping my P2 card in the field.
option 1: P2 store- problem: waaay too much money+have to swap out the p2 card.
option 2:self powered USB2 OTG device -problem: P.O.S.+ no LCD for file transfer progress.
option 3: 2.5 inch firewire drive. -problem: NO ONE makes a self powered(not bus powered) firewire case.

So there are those who have come up with a solution for option #3,

BUT its hideous (no offense) and probably doesnt last that long.
and a lithium ion battery pack for the firewire casing isnt feasible because the spin-up process of the harddrive requires voltage that the lithium-ion pack cant provide.
SO. This is what I propose to my fellow intelligent dvxuser forum compadres:
Lets make a DVX/HVX battery charger hack to allow us to use our existing lithium ion batterys to power a 2.5 inch Firewire drive housing!!!
I know that there are plenty of uber cheap battery chargers out there that will fit the bill- This seems like the perfect solution to me let me know what you think!!!
:dankk2:
 
I'm totally with you, but how is it that the issue is the charger? As you say, the drives spin up drain is more than the batteries can supply, how is it that the charger would address this issue? Are you sure the batteries cannot support the spin up drain? Tell me more about what you know on this. Perhaps there is a way to allow for a slow spin up that would not overly tax the battery circuits.

Perhaps two batteries could be used in parallel.
 
Mmm, not sure what the question is in the initial post...

I've been using a couple of 2.5 inch 80 gb drives for a year now, travelling far and wide with them. I haven't had a problem yet. Of course, I treat them with care but that goes without saying - being gentle with any hard drive is probably a good idea, no matter what size and no matter the advances made in dampening them.

Half the time, I can have my laptop on hand and just dump the p2 cards directly.
The rest of the time, I have one of the 80gb 2.5 inch drives in a FW enclosure, powered by a hack similar to the one linked to above. It works just fine.
