I have connected 19 "small" homemade batteries into one realy,
realy huge battery. After some tests and after fixing some problems
with volmeter, i have this situation:

One "small" battery:
DCV : 2,53 V
DCAmps: : 0,5 mA

Huge battery:
DCV : 48V
DCAmps : 24 mA

I believe your math is a bit off. It would take 912 (not 19) 2.53V .5mA
cells to make a 48V 24mA battery. To wit:

48V * 24mA = 1152VA

2.53V * 0.5mA * 19 = 24.035VA

1152VA / 24VA = 48

So you need 48 columns of 19 rows of 2.5V .5mA cells. Only 47 more to go.
Keep us posted.

))))))
I didn't laugh so much for some time J. Holly shit, now i have to sing
Ťwith tears in my eyes Ť. The fat kid, the bike, 6-8 kids, the
mcDonalds etc. )

I've always wondered why a bike hooked up to an dynamo with fat
children on it peddling wouldn't work? ))))))))))

Just stick the fat kids on the power bikes in the garden. It'd
probably work in Iran, but let's not go there. ))))))))))

Becuse i am european and catolic i could find some good german girls
over 150 kg and tell them that this pedalling is for spirutual
enlighment and for waste of fat )

//------------------------------------------------------------------------------
Anyway, back to the problem...

The enlightment:
***
The battery is big in design (48 V) but its really light (don't have to
worry about the floor )

Do you have $4000 or more to invest?
***The design is rather simple and i dont have much costs.

charging the batteries
*** I have solar panel for this purpose
//---------------------------------------------------------------------------------

Second enlightment :
I have changed the design and now i have 1 DCV and 1,2 miliAmps small
battery (cell).
I conected two small battery's and i get 2 DCV and 2,1 miliAmps.

Tests:
If i connect additional two ( all togehter 4 ) i get 4 DCV on 4,15
miliAmps.
If i connect cell to voltmeter and if i measure discharge of that cell,
then the total discharge
( with voltmeter resistor ) would be 14 days.

//-----------------------------------------------------------------------------------
Question is still the same:
How would you encrease the needed power ?
What do you think of the capasitor idea ?

Mark

p.s. OK, this looks like Ťunpossibleť project but i will not give
up...
So keep that optimistic spirit and please give me answers to my
questions.
Keep cool )

Gee, thanks. I really needed that word for word translation from Chinese
without any grammatical or syntactical corrections.

I think the problem here is that "newsgroup" doesn't translate into far
Eastern languages very well?!!?
Perhaps it comes out as "dump your rubbish here" ??

Cross-posting doesn't help. either.

If you want to run a 1KW 48 volt inverter, you will need a battery
that will deliver 25 amps or more, for as long as you want to run the
inverter - your home-brew cells are totally inadequate for the task,
and you can't do anything with capacitors or other things to make it
work.

If only. He multi posted it.

Did you say *homemade* batteries? What are you making them from?
Lemons?

Well, even if you have 48V (that's a lot of lemons with nails sticking
out of them), at 0.024 A, that's a whopping one Watt of power you're
producing. (Ok, 1,15 W.)

You need a battery array about a thousand times bigger to run a 1kW
inverter.

Why not make a one-watt inverter?

Yes. Read what I posted before, which should help you realize that you
cannot square capacity by doubling cells. Unless, of course, the factor is
two, which in this case, it is not.
