Thanks... problem was resolved
In my case the problem was in battery hold box... sometimes it doesn’t hold battery normal and that why connection was bed
Yes, it's a powering problem. I've used Olight batteries. They seem to have a very low safe current setting.
Sounds like undervoltage. Check your batteries.
