Re: RXV HV/LV BMS Shutdowns
The 12v/24v rating on that light is part of the problem, it has a higher value resistor than a 12v light so it can also work at 24v.
A typical 12 LED would be dropping around 8v at that pack voltage. At those voltage ranges all you need is a plain LED and no resistors, or no LED at all in the circuit. Sometimes the resistor is easily spotted in the light wires and you can just by-pass it, otherwise you can use without the indicator light. |

Thank you for all your help! How can I test that it works? If I were to jack the back up and get the wheels spinning if I then shut down my battery with my big disconnect switch would that simulate it? |

Re: RXV HV/LV BMS Shutdowns
Don't disconnect the pack, you need to disable the BMS to test the Controller lockout function.
Does your BMS have Bluetooth or any other switch to disable it? The BMS is what needs to be tested since you already know if that relay does not close the cart will not move. |

If the power is cut completely does that mean the RXV locks the brake? Eg if I cut the power off at the battery etc? |

Re: RXV HV/LV BMS Shutdowns
That is my understanding, removing power will lock the wheels and apparently some Controllers are also more susceptible to settings corruption if power is removed while to Controller is working.
Without being able to temporarily change the settings to force a shutdown, I don't know of any safe way to cause the BMS to trigger on LV or HV. You need to check any manuals or with the place you got the pack to understand the procedure to unlock the BMS if it does shutdown. |
