of course you can cool batteries. basically one system should be built in such a way that all parts of it are suitable. if the battery gets too hot, it is not suitable for it! if you air-cool the cells from the outside, the internal resistance of the cells does not change. the inner heat is still the same as before. if you now cool with air from the outside, there is a greater difference in the cells. outside and inside. the cell will lose power faster, will not endure as many cycles. there is a way to keep the temperature stable: this requires liquid cooling / heating. the cells can then be brought up to the ideal temperature. The Kreisel company from Austria does this for special conversions to electric cars. to eppg. there are already cells available on the market for everyone that are ideally suited for eppg. you just have to use them. it may sound strange … currently I fly a lot at around plus +5 degrees celsius to - 15 degrees celsius. I use a special neoprene cover to protect the batteries from the cold in flight. because that would also damage the cells if the outer cells are colder than the inner ones. https://www.kreiselelectric.com/en/
