FAQs
If you notice significantly reduced flight time, power drops, or unexpected shutdowns, or see bulging, damage, or abnormal charging, the battery is likely aged and should be replaced.
It’s not recommended. Voltage levels, discharge curves, and connector designs may differ between brands. Mixing batteries can cause instability or damage. Always use original or certified compatible batteries.
