What causes the charger output current to be unstable
Charger current magnitude affects battery 1. Since the absorption current is greater than the supply current, the power supply is in an overload state, which may cause overload and damage of the charger device, overheating damage, and encounter a power source with poor quality or lack of protection measures, and even a risk of fire.
Current Limiting and Voltage Scaling — Copter documentation
Current Limiting This protection automatically drops the throttle to as low as 60% of full throttle in order to limit the current requested from the battery. This can be useful to protect the battery from damage. To enable the feature, set the MOT_BAT_CURR_MAX parameter to the desired limit in amps (or "0" to disable this feature). ...
