Generally, as temperature decreases, the capacity of most batteries also decreases. This phenomenon is particularly evident in lithium-ion batteries, which find wide usage in
Lead Acid Battery Freeze Chart Temperature vs State of Charge. To put it another way, a lead acid battery freezing point will be -40F if it''s down 20% from a full charge. Or -22F if it''s down 40% from full charge. Or it will freeze at 14F if it''s down 70% from a full charge.
At least, a lead acid battery will just melt your wires, whereas a LiPo will melt your wires then and explode. In your use case the problem is temperature.

The effect of strap melt temperature on the quality of cast-on-strap joints is shown in Fig. 6. For the sample cast at 430 °C (the lowest melt temperature), the lugs were all separated from the strap due to the lack of fusion over the entire joints. For a high quality joint, besides the complete wetting of the lug by the molten strap alloy
For example, a lead-acid battery that is expected to last for 10 years at 77°F, will only last 5 years if it is operated at 92°F, and just a year and
