Hello. When I insert the battery, charging starts. The fan works, but it stops immediately and cuts off the charging. I checked and measured the entire circuit, but I could not find any defective parts. 5V standby voltage appears. I tried 6 different batteries, all of them are the same. Is there anyone who has this problem or has experience?
