Difficulty: EasyTime: 10 minutes0 things you need

Is this your problem?

  • Scooter switches off on a hill at 20–30%
  • E-05 on the display
  • Percentage jumps around

Likely causes

1
Battery low and tiredHow to tell: Voltage drops when you accelerate hard at low charge.
2
P03 setting wrongHow to tell: Joyor says E-05 also shows if P03 is not set to 60.
3
Loose battery connectionHow to tell: Cuts out over bumps too.
Check this first

Charge fully and try again. Check the P03 setting on the display.

What you need

Nothing but a few minutes.

Step by step

Tap a step when it’s done to keep your place.

  1. Charge fully with the original charger

    Then ride normally.

  2. Check P03 = 60

    Your manual shows how to open the P-settings. P03 is the battery voltage and should be 60.

  3. Ride gentler at low charge

    Lower mode, softer throttle below about 20%.

Stay safe

  • Anything inside the battery pack, or a pack that is swollen, hot, smells or has been dropped hard. Stop using it and take it to a shop that works on e-scooter batteries.

When to take it to a shop

If it cuts out over bumps (a loose connection inside the deck), or at high charge.
