Yes; looks okay.

The temp sensor needs to be taped to one of the lipos or between them, but not in a manner where it’s going to put pressure on them or poke a hole in them when the board gets banged around.


what is the purpose of it? its not a smart bms and im bypassing discharge

It will shut down charging if the cells are too hot.

Also if you decide to add lights later

in this manner, then your lights turning off could tell you to pull over and stop because you have a battery emergency underway. Without the placed sensor, it can’t do that.
