off for 18 hours
Very rainy day, could have run plenty, but the code prioritized charging batteries instead since it was not very warm, and I mostly agreed with it.
Good opportunity to see how the temps develop over time. I think having part at 2.5C after 18 hours off is very good, and it was all below 6C until noon. (Outside temp ranged 19-22C)
Now below 2C, after a mere 1 hour running today.
