Critical battery voltage in cold weather?

[KevMo Photog]

So what is the critical voltage to be aware of while flying? Gonna be doing some 28-30 degrees stuff tomorrow. Def gonna start with warm batteries and then let it warm up in a hover for a couple min too most likely. So each cell is 3.8v. And the battery voltage indicator gives you a one cell voltage. So wha'ts the danger level of one cell?

We are only going to get to 44° tmrw and I want to fly. Is there temp range we should fly in?

Sure appreciate the reply link msinger! So it is only showing you one cell voltage up the top right? Will that turn into a warning color if voltage gets too low in one cell or how does that work on that displayed value it shows?

I fly in single digit temps without issue. The battery will drain a bit faster.

That's showing you the voltage of the lowest cell -- which is all that matters. Once the lowest cell reaches 3.0V, the battery will shut off.

Perfect! Had no idea why just one voltage. Thanks for that very good info man!

Im sure he was prob talking about F FantomPhlyer. I flew today in 25 degrees and had no issues at all btw.

i have done a few sub zero flights, i keep my batteries in the truck till I'm ready and i keep my flights short 5-10 min max. Today was at -9F or -23c.

Wow! That's cold man! I couldn't keep my fingers warm even at 25F. LOL
