Ey!
somebody has a great idea on how to charge 1000 lithium polymer (lipo) batteries?
With 1000 chargers . . . .? 
Tesla uses over 3000 batteries (NOT LIPO) in their car battery.
The battery, the motor, the inverter that powers the motor and the charger all have automobile coolant circulating through them which is cooled by a fan and radiator through which the coolant circulates. The problem with attempting to charge multiple LIPO batteries in parallel is that the job of a LIPO charger is to make sure EACH CELL is in fact charging and shutdown the process if one cell is shorted, open or not charging.
Attempting to charge 1000 LIPO batteries without following this procedure is a recipe for disaster because the symptom of a failed cell during charging is it heats up and the gases cause it to swell like a baloon being inflated. Any RC hobbyist can tell you that when that happens you need to disconnect it from the charger and get it the hell away from anything flamable before it bursts into flames. If you want to risk igniting 1000 Lipo batteries then you can expect Homeland Security to pay you a visit, in force.
With 1000 of these:
That should work. Don't forget to order the Thermal Sensors. You can probably get a volume price for everything.
Why on earth do you need 1000?
You can get big cells and use fewer of them.

All in Parallel = massive amps ?
or
All in Series = massive volts ?
or
some combination thereof ?
Is this an EV project?
That's a boatload of connectors! What kind are needed for the batteries?
@CrossRoads: jst connector, 3.7v Lipo Batteries. I still dont know how many Amperes.
Obviously "with one thousands of these..." is not the answer that I am looking for. This is something anybody can realize. I would like to figure out a more efficient way; a single machine that can perform this operation.
I dont know what an "EV project" is. and I dont know if in parallel or series. I know that I need to charge them. As many as them as I can at once. Perhaps I can build a charger that works with 200 of them, and perform 5 charges.
You won't find a single charger for 1000 cells. 16 cells perhaps, but not 1000.
thanks markt. very helpful
I will wait anyway a bit longer to see if somebody else comes with some practical solution
They can't, charging thousands of these batteries in parallel is at best going to yield many undercharges/overcharges and at the worst a firestorm.
By the way EV = electric vehicle

When LiPo cells are in parallel they will all be at the same voltage. It's good idea to make sure they're all close to the same voltage when connecting them together since the higher voltage cells will discharge into the lower voltage cells.
There are lots of articles online about charging LiPo cells in parallel. As long as the cells' chemistries are the same, they should be able to be charged in parallel.
Parallel charging doesn't work for all battery chemistries. I don't think NiMH cells can be charged in parallel but I've read a bunch of articles from people I think are reliable sources who state it's fine to charge LiPo cells in parallel.
Apparently the cells don't even have to be the same capacity. As I mentioned earlier, they should be near the same voltage when connected in parallel.
Make sure the bus bars don't short out, with that sort of current sourcing ability it would
vaporize a lot of copper or aluminium very quickly.
I fail to see the use of a 1000P LiPo pack, that sort of power needs hundreds of volts to
allow for sensible wire diameters. 6 inch diameter copper rod is not easy to handle, and
~100kA will cause large forces between conductors too.
If you have to restack the cells from another arrangement to all parallel just to charge them,
you will get very bored very quickly.

1000 LiPo cells practical? Absolutely not.
My point is that anything using a 1000 LiPo cells is likely to fail, and fail spectacularly. The risk
of a single LiPo going bad is finite and real, use 1000 and you have 1000 times the risk - that
makes it very probable.
1000 Li Ion cells - possible, see Tesla's approach to batteries. http://www.teslamotorsclub.com/showthread.php/31831-Battery-interior-and-Repair-of-Model-S
~10 large LiPo cells - possible - still have to take precautions about fire risk.
Even big engineering companies are bitten by this. 2013 Boeing 787 Dreamliner grounding - Wikipedia (And that was only a few Li ion cells)
Maybe if the OP could tell us what purpose the batteries are being put too, and some more details about the batterys capacity, but there is no easy way to do what is being asked.

Find a used Charger for an Electric Vehicle than can be programmed to your voltage and amps?
Series Charging = Higher Voltage and low amps
One Battery Management Chip per battery?
Charge multiple series strings, but not in parallel.

Tesla uses the NCA type of Lithium Ion battery:
LiNiCoAlO2 = Lithium Nickel Cobalt Aluminum Oxide
It has a very high Specific Energy rating.
I have to feed 1000 led strips in 1000 different places at the same time. for this I need 1000 of something that feeds them. I am currently using 9 volts batteries for my prototypes, that are 20, but when I go up to 1000 pieces, it will be a big pile of electric garbage if I have to dispose 1000 9volts batteries. So, I was thinking on using 3.7volts lipo rechargable batteries
