That is also possible too. The only reason I mentioned 750UP firmware is because I have some old ones that suffered from the firmware issue. It's now the first thing I check before powering devices with it.
I personally haven't had much issue with NanoBeams in the cold weather. We have seen some cold weather here in KY we haven't seen in a long time and luckily **fingers crossed** we haven't had issues with them.
