AutoQuad Forum

I'm going to try 5S LiPos on my AutoQuad Y6. I have ESC32's and a really compact power distribution board:


The battery leads are about 25cm long (=lead from power distribution board + lead on battery). I have currently 35V 330uF caps (supplied with ESC32) installed near every ESC32.

I read from the wiki (http://autoquad.org/wiki/wiki/esc32/esc ... are-setup/) that one should use 50V lowESR caps when flying 5S. I guess I should change my current caps, then?

I have a few questions:
1) When a cap is considered "lowESR" for this application? What value of Equivalent Series Resistance? I tried searching eBay for 50V lowESR caps but could not find any big enough.
2) What capacitance should I use? I draw less than 10A per ESC (6000mAh juice used in a 8 minute flight).

The standard cap is a Panasonic EEUFC1V331B. Its ESR is 68 millohms. Its 50V counterpart is EEUFC1H331L, 60 millohms

Yes, 330uF should be more than enough. Do mind the can size. I realize that the 50V caps are usually bigger than the 35V ones.
