9V with 4Ah issue

[Acetronics2]

Hi, Selcurity

Adding two batteries is not possible here without creating a new adapter.

reaching one hour autonomy nor ...


For once, could you tell us what exists as a regulation ... you want to make work YOUR thing without changing anything ...

and it doesn't work yet !!! ... really funny.




Heuuuu, by the way ... LT 1083 EXISTS in fixed 5v output ...

Damned, ... its possible !

I wonder how far the battery voltage will drop under a 4A load...and if that battery voltage will be enough for even the LT1083 to still regulate properly...

Hi, Ski

1.3v @ 7.5A ... that's Ok !

Note the MIC 2975x ... might only drop .3 to .5 v ( from my souvenirs )

But now ... 6 AA "hicap" NiMh cells should be around 0.45 Ohms internal resistance ... (0.223 - 0.3 measured for 4 CELL !!! )

a bit more for the wiring and awful connections ...

YOU WIN !!!

But 6 Sub C ... hé,hé ...

You mean like this?

What do I win?

Apparently that would require some sort of redesign...
Sub-C just might handle the load

You mean Ted's work, I suppose ...

for sure !

Acetronics, you are right: skimask, Ted's, mackrackit and Security are all the same person: me. Maybe "Get a life" is not such a bad advice I can give you here.
