Controller works with Xiaomi apps and can be modified/flashed with custom firmware for increased speed.

Traces are fully reinforced. They come with copper bars down the traces but it is not enough. They have been further reinforced from stock.

Does NOT come with 100v capacitors. But has suitable MOSFETs for 20S (84v).

If you wish to mod this controller yourself you do not need to change the MOSFETs.
