Good point. "Cold" as in "below freezing" (0C, 32F) for charging, not
discharging. It seems like an arbitrary number (these batteries are not
made of water after all) but that's what they say. I'd recommend at
least several degrees above that for charging. If heading into the wave
with an LFP battery, if you have solar charging, you may want to
disconnect that (unless the charge controller does that automatically -
do the LFP-aware ones do that?). Would need a switch for that
disconnection. Otherwise it's another reason to avoid solar panels in
the glider, which can't help a lot with the battery running time anyway.
