3. How to store batteries to avoid any damage?

Batteries should be stored in a dry, cool place at room temperature.

For Li-Po batteries, it is recommended to keep them charged to approximately 50-60% (storage mode). Avoid both full discharge and prolonged exposure to a fully charged state.

It is also important not to leave the battery connected to a replica (especially one equipped with an ETU/MOSFET module) for extended periods, as this can lead to extreme discharge and permanent damage.
