Ive had a Bloomsky for about 2.5 years now, my unit was replaced about a year ago and now i'm starting to get the unit dropping offline for a few hours (until daylight happens again).
I assume this is the battery (although when it comes back online, i can see the battery voltage must be crashing precipitously because i never get any values that are very low (below about 90%) but when it comes back on, its down around 60-70% and then rapidly charges to nearly full.
So i assume the actual battery is getting old/defective (and its been raining a lot recently so im not getting some sun every day which it seems to like.
Has anyone actually replaced the battery or added capacity on these units? I'm perfectly ok with taking it apart and soldering, but i havent looked inside to see what its like.
