sorry I don't have a prothingie

but this does answer a question for me lmfao...the other day my TECs wasn't out of battery but I noticed the volts was listed at 3.2 instead of it's normal 3.6 - 4.2 and the system powered down...
I like chief don't usually wait til the battery is completely drained...usually every 2 days or when the battery level get's down to about 1/3 I let it charge over night....rather safe than sorry...been without pv's before not so much fun lmfao.
