Well, the guy wants me to come up with a min. order of 50+ to make it worth while...  Do we think we could sell 50 of these, at cost???  I'm not looking to make any profit off of this, I just want a cheap and reliable battery...  I bet they'll run about $40 per after shipping etc...  I'll ahve to talk to him more this wekeend...

For what kind of battery?  Same as the ones you linked to cause that is more than can get them for now?  Different voltages? user selectable or auto selecting?  mAh rating? metering? charger included? Tips included?  hardwired cable or plug in cable?  Need a lot more info before I can answer a commitment question.

Understandable...  That's why I've refrained from posting more than I have now...  I haven't promised anything, I just wanted cheap and reliable.  I just know this guy that knows people over there, and can probalby find us something good instead of someting crappy... 

However, you do bring up some good things to think about in what we would like as a final product.  Again, this guy is in development and manufacturing, so we may be able to specify what we want...

Again, let me talk to him this weekend and see what he can do...

i just want a dvd battery 9v 5400mah clone that doesn't cost half a C note.

would it be possible to run a couple RC batteries in series, heat shrink them together, and replace the in/out connectors with the same connectors as the dvd battery (that way you can use the same charger/power cables)?  you'd also need a voltage regulator in there somewhere too i guess....

Here's another thought.  I have cracked the case on a couple of my bad DVD batteries and you can get the cells they use new and even at higher rating than the 5400mAh.  I have not done a battery replacement only fixed a bad switch but the case can get superglued back together with little to no harm done.  So in essence we could "referb" the batteries and keep them running.   That does not address anything except the 9volt DVD batteries though.

that seems like the way to go...

is the battery swap just a simple in/out?  what kinda batteries would you go with?  off the rack energizer or duracells?

Most battery packs that I have dissected are made up of a configuration of 18650 lithium cells. This includes all battery geek packs, wally world DVD batteries, and the sony batteries used on our SD 7xx recorders.

http://www.batteryjunction.com/tenergy-18650-tab-2600.html

I had a good website saved, that I lost on my last computer crash, that explained how to identify the country of origin and the capacity of these cells by the color and the numbering.
If I recall, the best cells were from Japan and Taiwan, the worst from China.


These cells are relatively easy to find and work with, although they have more than double in price over the last few years. In most cases the cells would need to be soldered together.

Chances are if your battery pack dies, it is from the cells going bad and not the charging or voltage regulating circuits. So by installing new cells, you should be able to bring a bad battery pack back to life.

They are made up of six 18650 batteries.  I'll try to post a picture of one opened up later.  You can find them all over E-Bay at varying capacities & prices.  I'd get the ones with the solder tabs.  Yes you will need basic soldering skills to do the swap.  But it restores them to new condition for much less than $50

I"d just like something that worked just like the Tekkeon 3450 but a) could power dual items not just using the USB and b) cost less.

So here ya go.  This was a brand new battery that I opened the package on.  Never took a charge and you can see why with the leaking cells.  6000mAh version.  A quick look at ebay I though it looked like $4-$6/EA for the largest capacity cells.

OK what hell,  I'll do DVD battery referbs.  You pay for batteries and shipping costs plus $10 for the work.  To upgrade the capacity to about 10,000 plus mAh Battery cost will be no more than $40.  Less power cost less.  below are some of the highest capacity batteries out there. 

The way the DVD packs are set up is three cells made into pack parallel and then wired together  3.7v x 3 = 11.1 volts which is stepped down through it's circuitry. 4200mAh x 3 batteries = 12,600 mAh capacity. I'm sure we lose a little of that in the step down process so I'd round off to about 10,000 mAh.  But I really am not exactly sure of the exact figure.  But it's way more than the stock battery  Original batteries look to be 2000 or 2300 mAh capacity.  which I assume returns the 5400 & 6000 mAh rating that the packs had.  Here are a couple links so you get the idea.

Only batteries with tabs please.  Hit me up via PM for address etc.   No rush orders please, this is a side project.

I'm kinda confused.  If they wired 3 - 3.7's parallel, wouldn't that be 3.7v  and 4200mAh x 3 = 12,600 mAh?
(Voltage additive in series, amperage additive in parallel)

It looks like 2 parallel packs (each 3.7v) in series or 7.4v, with amperage additive in parallel to 12,600 mAh.
Total would be 7.4v - 12,600mAh.  Could that be stepped up to 9v? (lowering the amperage)
I'm just going by the look of the crimped end of the cells.

Sorry if I'm in OZ.

Dave actually after you pointed it out your right so they step up the voltage....hmmm let me give this thing a good looking over.  they'd have to be in series to up the voltage.  The darn ends look so similar....more later
