Opened her up to have a more thorough inspection. Thought to share the pics also :D
Here are some pics, all looks fine besides where the 3 motor wires go in the board, but couldn't get the board off the top aluminum piece.
Anyone has any ideas how to pry it open, the 3 motor wires look a bit over heated, with brownish stains.
The top and bottom alum case parts slide open to get to the inside.
These are all the pieces of the Mamba XL2
always thought there were only 2x 680uf 35V capacitors, but there are another 2x 560uf 35V capacitors also
The small board can be easily removed, its just plugged on the main board.
Close up pics of the small board
The other side of the main board, but couldn't get it out of the casing.
This is where the fault appears, as the wires seem burnt a little, although I recall the smoke was from the batt wires side. need to get the board off to have a closer inspection. but dunno how.
