Note: Keep batteries between 15-35C for optimal performance. LiFePO4 tolerates cold better than NMC. Heat is the primary enemy of battery longevity.
Reference
Effective Capacity = Nominal x (Capacity% / 100)
Capacity% varies by chemistry and temperature
Resistance increases ~2-3% per degree below 0C
Cycle life degrades at high temperatures (Arrhenius)
