Velotric Discover 2, Nomad 2 and Nomad 2X: battery indicator lights flashing

You press the battery's level button on your Velotric Discover 2, Nomad 2 or Nomad 2X, and instead of a steady charge reading some of the lights flash. The bike may not power on or the battery may not charge. On all three bikes, these flash patterns are battery error codes (Discover 2 manual, Nomad 2 manual, Nomad 2X manual). Short answer: read the pattern. One means check the bike or charger, one means the battery is too cold or too hot, and one means the battery is faulty and should not be used.

Battery light patterns

The patterns are the same on all three bikes (Discover 2, Nomad 2, Nomad 2X):

• 2nd and 4th lights flashing, 3rd steady: check the e-bike or the charger for a problem.
• 1st and 5th lights flashing, 3rd steady: a temperature issue. Keep the battery at 50 to 77°F (10 to 25°C) for at least an hour.
• All lights flashing: the battery is faulty and can no longer be used.

Most likely cause

The battery's own management system shows these patterns when it sees a condition it won't work through. The temperature pattern is common after a bike sits in a cold garage or a hot car. A battery outside its charging range won't charge, and the fix is the same hour at 50 to 77°F (Nomad 2X manual). The "check the bike or charger" pattern points away from the battery cells themselves and toward the charger, the connection, or the bike side.

Other causes to rule out

• A charger fault. Velotric's charger shows solid red while charging and solid green when full. Flashing red while charging means a charging fault: unplug and contact Velotric (Discover 2 manual). See check your charger.
• A poor charger connection, a damaged charger or damaged wiring, all common causes of a battery that won't charge (Nomad 2 manual).
• An over discharged battery after long storage. A battery left unused at low charge can enter a protection state. Don't keep trying to charge or revive it; contact Velotric support and describe the storage (Velotric troubleshooting guide).

How to confirm

1. Note the exact pattern before you do anything else. A photo helps support.
2. For the temperature pattern, bring the battery indoors and leave it at room temperature for at least an hour, then check again (Nomad 2X manual).
3. For the bike or charger pattern, unplug the charger, check the charge port and plug for dirt or damage, and try another wall outlet (Velotric troubleshooting guide).
4. Watch the charger light while charging. Solid red is normal. Flashing red means stop and contact Velotric (Discover 2 manual).
5. If you can, try a known-good Velotric charger of the same model. Never use a charger from another brand or voltage.
6. Reseat the battery fully in the frame and check the contacts are clean and dry before trying the bike.

Fix options

Warm or cool the battery (easy)

The fix for the temperature pattern. Free.

Replace the charger (easy)

If the charger flashes red or a known-good charger works, buy the matching Velotric charger. Velotric's support page links its parts and accessories store, which lists batteries and other parts (Velotric support).

Replace the battery (Velotric support)

If all lights flash, the battery can no longer be used. Contact Velotric for a replacement, and recycle the old pack through a battery drop off, never household trash. See e-bike battery care.

When to get a pro

Contact Velotric or a shop if the pattern returns after warming, if a known-good charger doesn't help, or if the bike side may be at fault. See battery won't charge, store your battery for winter and Velotric troubleshooting.
