"My controller is chagred but behaves as if it has no charge."に関する回答I had this problem with my son’s motion controllers. I took the batteries out and charged them separately using a bench power supply set to 4.2v and 1.3A maximum. Once the current had dropped below 700mA I reinstalled them and they now work normally. It appears that when the batteries are deeply discharged, the USB charging can’t cope and they need some more powerful charging. I hope that helps.
