Are akk ok or not ? which one is good ?

The circuits have no obvious problems, but if they work as YOU want is something else, note the differences i.e. gell batteries/switch to trickle charge etc.

Ok thanks here the input voltage is given 17-30 volts , so is it compulsary to apply 17 volts in minimum ?

& what if i use to make a total of 12 volts 1 Ah from 3 single battries of each 4 volts 1 Ah (in series) ??? Is it compact woth the circuit ??

17V is the min

4V lead-acid batteries?

hmm ya 4 volts 1 mA & 1.0 mAh SUNCA lead acid batteries (old type)

IF the batteries are in good condition and about the same charge state it should be ok.

ok then let me proceed first

Sir , what changes we need in component's value if we apply same circuit for

!) 4 volts
&
2) 8 volts

please explain it for both ! thanks
