Wiring D2flex...

[Fichtenelch]

Hi,
just got my d2flex from taskled today and i'm kind of worried about the resistor i need to limit the current.

I'm planning to use a WM-F3 bin SST-90 and a 3-cell sub-c nimh pack. maximum current of the d2flex is 6A, is that correct?

So, according to taskled's website:

(Vbat - TotalVf) = V
Next we calculate the necessary resistance we need to add:
V = I x R, or R = V / I

So, at the moment i don't know how about the voltage of my battery pack when it's fully charged, can i just assume it with 3.6V? Or should i just take my dmm?


Next thing is, where to put the resistor (between d2flex and led+ or led- should be correct, or?) and how much power does it need to take?

Can't help with the resistor, but Geoge sent me this back in December. I asked for the 9A version of the D2flex and this was his reply.

"All d2flex now have the higher current capable FET.
cheers,
george."


Thanks,
Frank

Now this is good news how can i recognize that i have the 9A version?

Ok i just got mail from taskled and he told me that the fet is rated for up to 16A. he is only de-rating it to ensure operation under all thermal conditions.
However, he told me that i propably won't need a current limiting resistor.
