Arctic batteries

Batteries don't well if THEY are cold. If they are just sitting a long time where the ambient temperature is cold, they will be cold. But if they are in use, being charged or discharged, anothr matter. Not 100% efficient in either direction, and that (hopefu;;y small) difference ends up as heat. Especially with big batteries, large ratio of volume to surface area, COOLING SYSTEMS might be needed.dan_b wrote: ↑Sun May 18, 2025 7:12 am https://renews.biz/100635/sungrow-insta ... ic-circle/
But batteries don’t work in the cold…
