Adaptom3 SE is a smart adapter, specially created to help you correctly store and maintain your Phantom 3 series flight batteries. It makes your battery maintenance and storage process easier, faster and safer. Two modes have been designed to suit your individual needs better in discharging the battery. One is the full discharging function where the battery can be fully discharged, and the other is the conditioned auto-discharging function where the battery will automatically discharge to its nominal voltage. Adaptom3 SE changes your battery into a power bank to charge USB devices! With Adaptom3 SE, the power can be reused when the battery needs to be discharged, even the Remaining Juice of the battery can be used to fully charge an iPhone 6S though the battery does not support a flight anymore.
