Cold weather performance is an issue for the folks who replace their motorcycle battery with a lithium ion aftermarket upgrade. https://advrider.com/f/threads/

  I have a LiFEPO4 battery in my motorcycle, and even here in the bay area of California, I notice the change it its cranking ability on colder days. It's a real issue with the chemistry, as attempting to charge it while cold causes some unfavorable reactions as well, so relying on resistive heating to bring it up to temp isn't a great idea. It is kind of amusing that cranking it a few times until it peters out from lack of charge, waiting for the heat to spread internally, then firing it right up as the capacity recovered due to temperature overcompensates for the previous drain, is a valid thing to do.

    Have you tried heating blanket?

      For my location, it would be more trouble than it's worth. If I lived somewhere a little colder, though, I think some kind of thermal control would be a real necessity.
