How to replace the BMS (protective circuit board) of an electric bicycle battery or scooter battery

The bike lost power during the ride, even in a very short time of the ride. The key needs to be turned back on to turn the bike back on. And the voltage of the battery did not drop rapidly. It most likely means that the battery cell pack is intact but the battery BMS is broken. There are two reasons for the failure. One is that the discharge current of the original battery BMS cannot meet the high power output behavior of bicycles such as climbing hills. The current exceeded the limit of the BMS, so the power was cut off.
Another situation is that the BMS is broken.
