Really why the warning in the cf manual? So its not like 1200 mA blue dice, 1200 mA red dice 1200 white dice = 3600mA max discharge 3.5 mA = BOOOM? :D

cause if you run your luxeon current (main blade) at 2a, and don't limit your FoC, you will exceed the 3.5A.  You will need a resistor on the white just so you don't blow it out, but even if you don't put a resistor on the FoC, at 1.2A on the main blade you will be fine.  My sabers (2 of them anyway) run the main blade at 1.5A and the FoC without resistors and my packs are fine.  trustfire packs for those who are counting, with a 3.5A max discharge on one of them for sure.

Thought it might be of interest for more people...

Im still a bit confused...

1. If I set the CF to lets say 1500 mA and drive two dices either in parallel or series, both get 1500 mA?
(Or is it like 1500 mA + 1500 mA = 3000 mA? Any difference betwenn wiring in series or parallel?)

2. If I give the FoC dice 1500 mA via the resistor a total of 3000 mA (not 4500 mA) will be drawn from the battpack?
Being 1500 mA from RB main dice and 1500 mA from the FoC dice?


Battpack max discharge is 3500 mA, so there wont be any danger?

Correct?

:D

Luminara? :P

What voltage is the batt pack as well?

2. Moreover if I output 1200 mA and the max discharge rate of the batt is 2000 mA do I have to use a resistor for the FoC die that limits the mA to 800?

Just a white clash.

Source voltage 7.4 v

 It looks like some need to study this http://en.wikipedia.org/wiki/Series_and_parallel_circuits before magic smoke is created.  ;)

Okay, because your source voltage is higher than your LED voltage it'll actually pull a bit LESS current. Best way to know is to meter the saber on the battery end for amperage.

i agree with m4co that this is a usefull read for beginners , myself i include here. ;).. but i would definitely have this board on the bench and configure it on basic settings untill i had a deeper understanding of multi die leds and pex boards and FOC.... you could still enjoy your CF-5 and its mighty powers and take your time and study the board in detail. ... remember its a CF-5 make absolutely sure you fully understand what you are doing otherwise its MAGIC SMOKE TIME and seriously that means :'( :'( :'( :'( time aswell.

yeah it kinda seems as even though my questions arent that hard to answer no one really did... ?
Im sure some could...

And its not like I was asking 100 or so :P

What I got from sunriders link is that in parallel the voltage remains the same and the current drops...

1. So if I want to give both main dices 1250 mA I have to configure the CF to output 2500 mA...? (Thats the max anyway.)
Given the fact that the battpack has a max discharge current of 3500 mA I can give up to 1000 mA for the FoC dice without blowing the battpack...?

In a series circuit the current remains the same and the voltage drops...

2. So if I wire both main dices in series I just have to configure the CF to output 1250 mA and both dices get these 1250 mA
I would have 2250 mA left for the FoC led?

Sidenote: Is the voltage drop avoided by the CF because it detects the Vf and outputs the correct one anyway? (Series circuit)

3. Any method prefered, like series over parallel or parallel over series?


Oh and would be kinda nice if someone could answer my previous questions:

If you know that your questions aren't that hard to answer, then why ask them?

CFv5 max is 2000mA, not 2500mA. Those batteries should work for what you are wanting to do.
I would suggest to invest in better batteries (AW brand) and read/understand the manual before you put the iron to the board.
