I have just commisioned a LiFePo4 charger. Flattery charging is inhibited below 1 oC
What I had not appreciated before this morning (-6 outside) is that: Condition = red BLINKENLIGHT
Apart from Too much information for the uniformed... it is just annoying.
The LED is green for normal (desired) and there is just enough room between LED and front panel for a bit of green filter gel.
Canna find anything at home, could buy some, but in the best traditions of YACF would anyone be able to spare me 10x10mm of something suitable?
BTW looking up wikipedia 'blinkenlight' made me chuckle
