Lightning storm

This is the second puzzle of my natural phenomenon sudoku series. I hope you enjoy it.
Solve online: CTC
Rules:
Normal sudoku rules apply.
Yellow lightning lines are thermometers. Along thermometers, digits must increase from the bulb end. The bulb must be deduced (the bulb cannot be in the middle of the line).
One cell in every row, column, and box is a charged cell, every digit 1-9 is charged exactly once. The charged cell must be orthogonally adjacent to a lightning line tip, and cannot be on the lightning line. The value of a charged cell is its digit plus the digit on the tip of the other side of the lightning (e.g. if R1C2 is a charged cell with a 7 and R4C4 is a 9, the charged cell value is 16). Lightning lines can be responsible for multiple charged cells if allowed by other rules.
Digits in cages must not repeat, and sum to the small number in the top left corner of the cage (values can repeat in cages).
Lösungscode: Column 1 digits from top to bottom.

The charged cells cannot be on any lightning line.

Can you clarify: The charged cell must be orthogonally adjacent to a lightning line tip, and cannot be on the lightning line.
Does this mean charged cell can't be on any lightning line, or just the one it is attached to?

The deadly pattern should be resolved by the charged cells containing the digits 1-9 exactly once.

Sorry for the confusion. Indeed the charged cells have to be adjacent to one end of the line regardless of it being a bulb or a tip.

The rules are a bit confusing, and I think I misunderstood them at first. I now think you're using 'tip' to refer to both ends of the thermos, and that the charged cells are all next to one end of a yellow line, but it could be tip or bulb of the thermo. If the charged cell is next to the tip of a thermo, its value is the charged digit + the bulb of that same thermo. If the charged cell is next to a bulb, then the value is charged cell + tip.
