The charger stops because bms shuts down because LOW TEMPERATURE.... Minus degrees.

Every charger will shut off..?any can help fix it won’t let charg my battery it’s stops charging after I plug charger thanks
 
Did you forget to plug in the temp sensors on the BMS?
I think it shows a negative value if you don't use it, in this case the BMS thinks it's freezing cold and will prohibit the Battery from being charged.

There are two solutions that I know of.
1. use the temp. sensor
2. reprogram it on the PC app to not use any temp sensors.
 
stop spamming your question.

calm down dude...its only one topic and hes may not that experienced using forums.
whats your idea to help with his bms?
it was 4 topics he was hijacking and 2 doubles he was also creating so he was asked to stop spamming. not knowing how a forum works does not apply if you are spamming the same copypaste everywere. most of them are deleted my mods already.

and my take is that either the bms posesses a form of AI unseen to man and started to use unused temperature sensor ports all y itself, the user enabled ports that are not in use, 3 temperature sensors all failed at the same time or wires are disconnected.

Yes, you need the UART box:

When I do angle configuration 170 it cutoff power battery is to weak I think ?

yes, and you need to lower motor current in the last tab.
 
When I do fully throttle turns off and starts flash 3 times and shows pedel error?

Maybe it's a wrong throttle type setting, try switching it to the other value indicated in the comment box.
