We've got modders and cable makers.  is anyone a battery maker?  Maybe something like RC batteries stuffed in a ratshack box?

Years & year ago I researched selling rechargeable batteries. To become a legal, AKA store type of, battery resale operation then you must be willing to accept batteries for recycle/disposal.  It didn't say you had to advertise it but had to be willing to do it.  The big kick in the ass was the mercury in batteries and that was before Li-ion.  I don't know if it is still true but it was a deal breaker at the time.  Batteries are a toxic area and I'm pretty sure that EPA laws have tightened up on all of that stuff. So being a "Battery Maker" seems like you either go totally legit in order to cover your ass with environmental laws or stay off the radar and pray that nothing bad comes back to haunt you.

Yeah, I could use an external 12-24v DC battery for my Sax. I can record a whole festival with just 4 sets of 4xAA's for my new LB :) And I can record a whole festy with my Sax w/ just 4 sets of 2x9v's :) Not too shabby IMO. Plus, a single change for each of my M10's and I'm set!

Could one get around it by specifying the LI-Ion battery pack the end user would purchase and install but selling a box that has a charger-indicator-variable voltage output?

So the guy that lives across the street from me is an "importer" from China.  He does manufacturing, design, development, etc.  I told him about how we wanted cheap but good batteries and how there were a lot of chinese options on ebay...  He is going to look into it for us and see if we can get a nice reliable battery...

Here is the link I sent him as an example...  We'll see what he come up with this weekend...

The Chinese Li-Ion are a good start...It would be nice to have three-four voltages ranges of 12v-9v-7.2v-6v and maybe a USB 5v slot, accurate charge remaining meter, Over charge-discharge protection. 50WH at minimum.

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

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.

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 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

Something "clicked" when I saw that photo.  I made a battery sled for my 680 by wiring two 8 AA cell holders in parallel, keeping that voltage around 10.6 but doubling the amperage for longer runtimes.

I have a couple of the 7.2v DVD batteries and the case is smaller; makes me think they use the same 6 cell config, just eliminated the "step-up" circuitry.
Just guessing, really.

OK so yes the batteries are parallel x 3 and the three pack is in series for 7.4volts total.  So to get 9 volts they step it up.  I had two bad packs and had forgotten that one was 7.2V.  So the red batteries are in a 7.2 volt pack.  The orange are in a 9V pack.  It was suggested  to make a box that the batteries could be replaced but after looking at it closer there is no way I have the skills to take that project on.  Too many parts, and too much of not knowing what the hell I'm doing.

UPDATE:  It looks like I can add the Tekeon 3450 to the refurbish list.  I cannot find a source for the stock battery pack but it measures out internally that the DVD style batteries will fit with just a little work.  To restore it to stock rating and capacity all you'll need is 2200mAh capacity batteries, which are some of the cheapest out there.  But I will need to charge $20 due to the retrofitting of the batteries and labor involved in rewiring a completely different style battery in place.  You could up the capacity if you wanted.  Your choice.  Here are pix of one opened up.

Sweet...so to increase capacity just order six of the 1 X UF 18650 3.7V Rechargeable Battery 4000mAh with Tab, same as DVD battery?

Oh...I was looking at another thread...what do you think of these?

http://www.all-battery.com/37volt-3200mah20cli-polycell.aspx

the 2200mAh was discontinued

Hmmm????

This one on ebay is too wide to fit them side by side. PLUS the have circuit board of some sort that is not on the originals.  That is the only kind I found on the web too. 

The Tenergy link is the correct one BUT @ $11/ea plus shipping I'd still opt to retro fit the 18650 style in the case.  You're at $66 just for those Tenergy batteries. about twice what the other cost.

Dimensions of existing cells:
(98-100)mm Long X (32-34)mm Wide X 5mm Thick.  Two stacks of three cells side by side.   MUST be six cells since each one has separate attachment point on circuit board.

The circuit board's twelve individual attachment points for each battery and the associated electronics are too complex for me to figure out if they can be circumvented.  I would only want to tie new batteries into the existing solder points.   Adn it does not appear that there is a direct replacement battery available for the Tekeon 3450

whats the size confines for the 3450 series if we are looking for replacements. If that's already been posted, my appologies.

No Page not exactly here is the space size limits:
70mm Wide X 100mm Long X 19mm High,  It is JUST enough height to fit six of the 18650 batteries as you can see by the photo.  I drew the black line with a sharpie to show halfway point.  And there is a picture of the circuit board they attach to. So I could attach six of the 18650 batteries with some wiring, shink wrap and patience and I think still get the case to close.  It will be right at the limit of the height.  Maybe it will have a wrap of gaff tape or extra large shrink wrap to ensure it is solid, we'll see.

This looks like it might be the replacement for tekkeon 3450

http://www.batteryspace.com/highpowerpolymerli-ioncell37v2200mah803495-25c814wh55adrainrate.aspx


Nope that won't work  :(.  Each cell is a total of 8mm thick which equates to a stack 24mm thick.  Won't fit inside the case.  At 19mm we are pushing the absolute limit of the case size.  18mm would be best fo a total thickness.  Remember it was to be six cells total, two stacks of three each side by side for this style battery to be a viable choice.

FWIW after spending about two hours digging on the web I only found one supplier that looks like they have that exact battery.  Not sure why it is so hard to find but I suspect it is due to the liability that these style batteries without a limiting circuit in place have the potential for fire/explosion.  There's a place in Korea and even with google translator I cannot begin to try and figure out if it's in stock, pricing or a way to contact them.  Then there is the fact they will most likely want a minimum order since they are a major manufacturer/supplier so unless we were ready to step up ab buy 200 pcs.  I don't know if it is even worth the effort.  Who's fluent in Korean?


Here is a side view.  They HAVE to be laid out this way in order to hit the solder points on the circuit board they attach to.

Ok, and if we opt not to go that route, there is a cylindrical battery that will fit instead? Just so long as it fits the 70x100x19mm bay area (including wiring tabs) and we get 6 of them, right?

Ok, and if we opt not to go that route, there is a cylindrical battery that will fit instead? Just so long as it fits the 70x100x19mm bay area (including wiring tabs) and we get 6 of them, right?
Yep the 18650 battery can be squeezed into the space.  See here:

If I were to go that route I just might put a big 1 or 2 inch wide piece of shrink wrap around the outside end of the case as an extra way to ensure everything is rock solid

I wonder what the max draw per cell is with the 3450 units. I'm assuming it would be when requesting 19v.

The reasoning is, most 18650 cells (over 2ah) are 2200mah (at 3.7v), but there are some higher densities but they have a different max draw rate.

Example: 2200mah, 2800mah

Page,  Those cells are each labeled at 2200mAh in the 3450.  Which is on the low end of the 18650 cells.   So, it stock it is using 6 X 3.7volts @ 2200mAh/ea   to power the 3450.  You can get up 4200mAh cells in the 18650 style which would more than double the capacity of a stock unit.  I was just contacted about the MP3300 which in the picture looks to be the same.  I'll know more once I open one up.

Curiosity got the better of me and I broke into an older Sony L mount battery labeled 7.2V 4600mAh.
This one dated 10/2005.



Lo and behold, the 18650 cell shows up again.



This pack is configured as 2P2S.  2 cells in parallel with 2 in series.
The upper strap is the center tap, where the +/- come together.
From this configuration we can conclude that the cells are rated at ~2300mAh each.
On the nominal side of the rating for today's cells.
This configuration would yield about 33Wh. 



The business end of this pack reveals the PCB which provides various functions that might include overvoltage, undervoltage, and short circuit protection.
This circuitry might also perform cell balancing on recharge.
The C terminal in the center communicates battery status.



So, without destroying it, we can deduce that the larger 7.2V 47.5Wh battery is the same 18650 cell configured as 3P2S.



Indeed 1/3 larger.



Careful surgery might allow replacement of the lower rated 2200mAh cells with cells of current manufacure that could produce 2800mAh.
This would give us about 60Wh, right at what our favorite Lenmar packs are giving us.
So without the addition of another parallel pair of cells and the increase in case size, we seem to be at the limit of the L mount capacity until another cell density improvement occurs.

After looking at your pictures I could up grade this too.  on the smaller 4 cell pack, I could do an upgrade that would get your total capacity to 8400mAh no problem.  I'd have to open one myself to see how hard the soldering work is inside but probably would be the same as I would get for the Tekeon, which is $20 for the work yo supply the cells.   I have decide that labor looks like it is about the same as the DVD battery so these will be $10/ea.  OR until I can get buried and find out that it is a lot harder than it looks, and at that time I'll adjust the pricing.  I could get the capacity up to 10,000mAh.  Thanks for the pictures Dr.FOB
