Phoenix-10 controller question
 

Hi Guys,

I have a quick question I hope you can help with.

I have a CastleCreations Phoenix-10 controller and mainly fly with 3 cell Lipo batteries, therefore I have set the autovoltage cutoff to Option 4 as per the manual. However, I also have a couple of 2 cell packs I like to use. However, whenever I start to fly with the 2 cell pack the motor cuts out due to the lower voltage of only 2 cells.

So, do I have to reprogram the controller every time I switch packs? Can I disable the voltage cutoff altogether and just stop flying when I see the performance reduce??

Any ideas?

Thanks,
Mark

I also would like to know the answer to this question.
WHat is the benefit of having an auto shutoff for low voltage?
I figure that the motor will stop long before the receiver ans servos!

Lithium batteries can be damaged of even fail completely if they are discharged below 3 volts per cell. The Phoenix 10 can be programmed for a 4 , 5 , 6 , 7.2, 9 12 volt cutoff. You could set the cutoff at 5 volts--the recommended 2 cell cutoff and carefully monitor your 3 cell pack when flying

Yes, set it for 2 cells but when flying 3 time your flights or land as SOON as the power begins to drop and you'll be okay. Don't run the pack too low or it ruins it.

Early Castle Creation documentation can be mis-leading. Per Castle Creations Technical Support, the correct setup is:
Feature 1 set to 3 = 2-cell Li-Po
Feature 1 set to 5 = 3-cell Li-Po

As voltage cut-off is the first Feature, it's pretty easy to re-program when swapping back and between 2 and 3 cells.
I find it worth the peace-of-mind. However, lots of people get away with leaving it programmed for 2-cells, then simply land when the 3-cell pack looses it's punch.

Bob

I just fly till I feel the power drop off. This with the voltage cutoff operating. On recharge they're allways over 11 volts. Same with the 7.4 volt batt.s
