Need Help! LiPo battery charge level for storage


New Member
So at the end of each summer drone flying season what is the best suggested battery charge level for safe storage. I saw some where that you should only charge your lithium polymer drone batteries to about the 50% level to avoid any possible expanding damage. Is that correct. I had fully charged my Eachine EX4 2 batteries at the end of last year's season, and they both expanded a lot and pushed off the case cover. So much swelling then made those batteries dangerous and not usable. Okay thanks.
