Can lithium batteries be used in high-altitude conditions? Answer: Yes, lithium batteries can be used in high-altitude conditions. However, it is important to note that their performance may be affected due to decreased oxygen levels and lower temperatures typically found at high altitudes. Special precautions and testing are often required to
The key to High Altitude Ballooning is to try to be as safe as possible at all times. The voltage supplied by batteries is temperature dependent and for most batteries when the temperature drops below 0 deg C they struggle to supply the necessary voltage. Lithium batteries however are far more resilient and nearly all flights use the
