Operating temperature and LiFePO4 batteries.
This is a good place to remind potential LiFePO4 users of the battery's chemistry limitations.
LiFePO4 batteries cannot be charged when the battery is below freezing.
Their protection circuitry will open, turning off the power.
This means they have to be located indoors where it's warm or kept warm for operation.
They can discharge at temperatures down to about 5 deg F.
I mention this for folks thinking about using LiFePO4 as batteries for remote solar power supplies.
