What’s Wrong?

Out-of-the-box Voltage Tiltback Thresholds and Battery Voltage Cutoff values do not align with recommended values! If left unchanged, you risk compromising your safety and/or damaging your battery.

Here’s what you need to fix, and why it matters:

1. Voltage Tiltback Thresholds

(Float Cfg > [Specs] > Voltage Tiltbacks)

These settings are responsible for alerting you when the battery voltage is too high (from regen) or too low (approaching a critical discharge level). Ignoring this can lead to nosedives and/or battery damage.

  • High Voltage Threshold: Set to 4.3V x Cell Count
    (Pint/X = 64.5V for 15 cells)
    Prevents damage from excessive regen.

  • Low Voltage Threshold: Set to 3.0V x Cell Count
    (Pint/X = 45.0V for 15 cells)
    Alerts the rider to stop and charge before the battery gets critically low.

2. Battery Voltage Cutoff Values

(Motor Cfg > [General] [Voltage])

These settings limit the current drawn from the battery as it approaches lower voltage levels to prevent deep discharge, which can permanently damage the cells. Some riders ignore Low Voltage Tiltback, so these cutoff values act as a backup to protect the battery.

  • Battery Voltage Cutoff Start: Set to 2.7V x Cell Count
    (Pint/X = 40.5V for 15 cells)
    Begins limiting current to protect the battery.

  • Battery Voltage Cutoff End: Set to 2.5V x Cell Count
    (Pint/X = 37.5V for 15 cells)
    Cuts off current to prevent critical damage.

Optional Rider Safety Adjustment:
If you want to prioritize rider safety over battery protection, you can use a 2.5V/2.0V approach for the Battery Voltage Cutoff values.

  • Start: 2.5V x Cell Count (37.5V for 15 cells)
  • End: 2.0V x Cell Count (30.0V for 15 cells)

Note: These values represent the absolute lowest end of the recommended discharge levels for these types of cells. Use them only if necessary and with caution.

:warning: Important Reminder:
DO NOT ignore Low Voltage Tiltback! It’s your first line of defense to protect both you and your battery. Battery Voltage Cutoff values are a backup, but respecting tiltback will save your cells and prevent sudden power loss.
