JK BMS restarting after 30 seconds

[dr.buckwheat]

I need some help guys. I purchased 3 DIY battery boxes with the JK PB2A16S20P BMS. I installed new 230ah Lipo cells and when I start the BMS, it shows an error light but there is no error listed.... after 30 seconds or so, it shuts off. Sometimes it will stall when turning it on and I have to do a hard reset with the reset button. The supplier said that 230ah cells are too small for a 200 amp BMS. However, I am not drawing any loads and they come configured at 40 amps of current from the factory...

Power on '66563 times' suggests the BMS is fitted incorrectly or has a fault.

Check the BMS sensing leads.
