Hi, He did test (twice) the capacity of the battery after the cold charges and found the capacity to be the same, so, at least in that sense, there was no immediate degradation. I guess what's bothering me is that there does not seem to be much of any data on what the actual effects of charging...

Hi, That's interesting the BattleBorn says its OK to charge down to 23F and maybe at lower temps if charging at a low rate? Can you say where this is on the BattleBorn site? The battery was in his freezer for 48 hours - seems likely it had a chance to cool down to nearly freezer temp. Just as...

His video covers 2 subjects - the second one covers the cold charging test on a 100AH LFP battery. Start at minute 7 of the video for the cold charging test - he covers all the details. I left a comment telling him he should publish the cold charging test as a separate video with an appropriate...

Hi, I ran across this video in which the person placed an LFP battery in a freezer for 48 hours, then immediately charged the battery (which has no low temperature charge protection), he then did a capacity test and the battery showed no loss in capacity. Being a bit surprised by this, he...

Hi, I just finished an Miles Per Gallon test on a rack that has some similarities to the rack in your picture... Full details on the test here.... Main idea was to compare mounting solar panels on a large rack vs mounting directly to the roof with minimal attachments. The difference is...

It seems like for your situation going with solar thermal pool heating would work better. The pool heating collectors are very efficient (75% ish) and cheap in that they are plastic and don't have to be glazed. You should be able to use the regular pool pump to circulate solar water as well as...
