between the various charging currents you want, and if 5% tolerances
in charging currents are acceptable, then the values of the resistors
will be:

Thank you guys !.
This is exactly what i need.

Good luck. Wouldn't of been my choice.

Nope, absolutely not. I wouldn't use your circuit for a charger of such
nature.. I was only trying to be nice to the originator asking for a
sensible circuit that would fit properly and safely, for their needs.

I think you flatter yourself a little too much, you really should
think of others and instead of passing on what you would like to ignore.

We have charging stations at work and none and I mean none of the
chargers are allowed to exceed 10% of the battery voltage, regardless of
condition. You on the other hand, would think it's ok to boil the
battery off, even after its has reached the peak voltage.

Personally, I don't care what you do with your own cells, you can do
what ever and take a chance of generating undesirable effects if you
wish. It's your choice, but to give others advise with out taking that
into consideration, thinking that maybe they don't care any more than
you do is pure foolishness.

BTW, that circuit you posted can be modified very simply to add
limiting voltage function, but since you're so self centered I'll allow
you the honor or making a mess out of it.

As for me being a registered radio operator, I have no idea what that
has to do with you throwing a tantrum.

The radio part is just a hobby to take me away from my regular duties.

I can't help it if you get all teary eyed when some one calls
you out on the advise you give out.

You better get used to people pointing out your design failures. It
happens to the best of them, even though at times don't want to
fess up to it.

Your "call-out", though, was invalid, rude, and uncalled for.
