Drone batteries are the most expensive consumable in the hobby, and how you treat them decides whether they last hundreds of cycles or fail early.

Charge with the correct charger, never unattended, and let hot batteries cool before charging. Do not store batteries fully charged for weeks; use storage mode or roughly half charge.

Store batteries cool and dry, away from heat and freezing cold, in a fireproof bag, and check them every month or two during off-seasons.

Land with twenty to thirty percent remaining, fly smoothly, inspect for swelling, and replace batteries when flight times drop noticeably.
