The indicator of charge from the rod from the handle
I want to share some useful advice. Maybe someone will come in handy. If you install a charge controller in the case, and the LEDs structurally shine in the wrong place. Cut a piece of the transparent rod from the handle, put it on the controller LEDs and fix it with a drop of hot glue. And insert the other end of the rod into the hole in the housing in the place you need. The light from the LEDs will go through the rod and at the end you will see a beautiful Hawkeye-type indicator. I did so in a flashlight. Here is what happened.
