Yes. The LED changes from red during charging to green when the battery is fully charged.
Before You Decide
Check the battery cell count, voltage and chemistry before choosing this charger. Make sure the pack is a 2S or 3S LiPo battery and that the 100-240V AC input suits your charging setup.
Using It in Practice
The charger is aimed at RC battery packs used in model cars, boats, drones, quadcopters and airsoft equipment. For the best match, compare the battery’s cell count and voltage with the charger rating before use.
Safe Use and Important Precautions
The stated protection features include overcurrent, overtemperature, short circuit and overvoltage protection. Follow the manufacturer’s instructions for charging and only use it with compatible 2S or 3S lithium packs.
Care, Cleaning and Storage
The charger has a fire-resistant PC shell. Keep it in suitable storage when not in use and check the unit’s condition before charging if it has been stored for a while.
What Else You May Need
A compatible 2S or 3S lithium battery pack is required. The charger is for battery charging rather than for supplying power to the model itself.
