I don’t think this is normal, the trace peeled/fell
off
That PCB definitely looks like it has seen better days.
Could anyone please help me with the type of the connector on the left? The right one is JST-PH2.0 PH-4Y for comparison
It goes to this connector. If that helps this is the bluetooth module of the LLT Smart BMS
Witdh of connector(socket in the background from above, I am happy to shoot a better picture if needed)
I tried to measure the space between slots.

You sure its ZH and not XH? I mean chars are next to each other and seems like
ZH’s pitch is 1.5 J.S.T. Mfg. Co., Ltd. (jst-mfg.com)
while XH is 2.5 according to jst’s product page which practically is equal to 2.54 from your reply J.S.T. Mfg. Co., Ltd. (jst-mfg.com)

Umm…yup…that antenna has ceased to be. 
Did it catch on something bouncing around in the enclosure?

Hey All. Having an issue w my main ride rn. It’s relatively minor but wanted to get some possible solutions.
Issue is that when I start my controllers up using the power button, more-often-than-not I get nothing when I hit the throttle. Roll to start and everything works fine. Puck is indicating it’s connected in both scenarios.
Controllers are TB6s connected over CAN and remote is a puck. TIA.
I’m not sure I had it inside of a 3d printed case I found for it on thingiverse.
Verrry strange. It takes a decent amount of concentrated force to rip a trace off like that. Though soldering for too long/too hot can lift the trace off the pcb and then it’s a lot easier to damage.
Wait…I just noticed this…are all those solder pads lifted off the pcb? That pcb was probably bent somehow.
At the very least you can expect increased resistance of that phase, which means more heating for the same current, which could lead to overheating and cooking the windings more, which would result in a motor that is fully toast.
I wouldn’t risk it, I see a gouge in the windings deeper in, not just the one obviously broken strand.
If it was just the one strand, you might be able to get away with it, as the change in resistance would be small, probably less than 5%. With that more extensive damage, the change will be more drastic.

do you need to split the 5volt and ground cable for using uart and power switch
Doing routine check on motors and I noticed I can push the shaft into the motor. It springs back but in comparison there’s minimal play on the other motor. What to do? Thanks in advance.

Do you notice a circle clip with some washers stacked at the bearing like the other motor?

The clips are still there on both motors and turn on the shaft as I torn the wheel.
