Battery is fully charged - checked with multimeter
Occasionally after disconnecting and reconnecting the battery manually the board will power up again.
The anti spark button illuminates when pressed but nothing powers up.
The input terminals of the anti spark only read 3v regardless whether the button is on/off.
Seems like it could also be the Y cable making the connection between the vesc : for instance it happens to me once one of the solder between the XT did brake under vibration causing the same issue maybe check that connection and change it to try.
If you only getting 3v at the anti spark input you battry is the issue/joints plugs up to it. Id expect as soon as you apply a load the v drop. Why you think you’r getting full voltage at the battry.
@RhinoTH Pleas can you confirm your measuring Voltage at the anti spark INPUT/SUPPLY to make sure we don’t going down a rabbit hole
I’m thinking Broken joint/super high resistance between p groups or BMS I don’t see any details on how the battry was built in you build thread only
Next I would get to the balance leads and confirm eatch p group voltage with your multimeter. Your BMS is separate so shouldn’t be to destructive to do so.
Then I would checks solder joints
The edge of your pack looks prity squar. Are your p group connections done with nickel if so did thay get beefed up like this
