Please follow the maintenance guidelines below:

1. Overcharging or deep discharging can seriously damage lithium batteries, especially liquid lithium-ion types.

2. Avoid charging for more than 12 hours at a time.

3. When the rotation speed slows down, turn off the device and recharge during idle time.

4. If not used frequently, recharge for 3–6 hours once a month and allow gradual discharge.
