Help with Electrifly C-20 ESC
I got an Electrify C-20 ESC. I'm planning on using it on my Slow Stick. Could that ESC be used with a Kokam 2 cell 1500 Mah Lithium poly pack?
Thanks in advance |

Yes, it will work fine. However, the LVC (low voltage cuttoff) is not set appropriately for lipolys. (many aren't) As soon as your power begins to sag, bring it down so as not to damage the cells by taking them to too low a voltage.

This is good advice as the Electrifly controllers I have tested have a lower low voltage cutoff setting than most - below even 2.5V per cell for a 2s lithium pack.
So, land as soon as you feel the power sag noticeably. Do NOT wait for the LVC to tell you when to land. |

Thanks guys! According to the specs, the lvc is set at the factory at 4.8 V. I wonder if that's to be trusted with the lipolys.

No. Convention has it at 3V/cell. Many planes will not fly at such low voltages anyway, but a floater like the slowstick will allow pushing them too far.
