Lectric XP4, XPeak 2 and XP Trike 2: E006 battery undervoltage, bike stops helping

E006 on the XP4, XPeak 2 and XP Trike 2 means battery undervoltage. The fix is a full charge. If E006 returns soon after charging, check the charger light, because a light that stays red can mean a worn battery.

Your Lectric XP4, XPeak 2 or XP Trike 2 shows E006 and stops giving power. On all three bikes, E006 is battery undervoltage, and a full charge is the most common solution (XP4 manual, XPeak 2 manual, XP Trike 2 manual). E006 appears when battery voltage drops below the usable level. The short answer: charge fully until the charger light turns green. If E006 keeps coming back on a full charge, the battery or charger needs a closer look from Lectric support.

This page involves the battery and charger. Never open the battery or charger, never repair a charger cord, and stop charging if anything smells hot or looks damaged. Leave battery diagnosis to Lectric support or a shop.

Most likely cause

The battery is simply too low for the controller to keep running the motor. The charger light is red while charging and green when done, and charging a mostly empty battery takes roughly 6 to 10 hours on the XP4 and up to about 8 hours on the XPeak 2 (XP4 manual, XPeak 2 manual).

Other causes to rule out

  • The charger isn't charging. If the charger light never comes on, check the cord connection and the wall outlet, then contact Lectric support. Don't repair the cord or charger. (XP4 manual)
  • A worn or faulty battery. If the charger light stays red and never turns green, the battery may be defective: contact Lectric support. (XP4 manual)
  • Charging in the cold or heat. Charge only between 32°F and 113°F. See store your battery for winter.
  • A battery left empty in storage. For weeks or months of storage, keep it at about 60 percent and never above 75 percent, and check it monthly (battery health article).

How to confirm

  1. Plug the charger into a working outlet, then into the battery, and watch the light turn red.
  2. Charge until it turns green. Unplug within about an hour of green, and don't charge for more than 12 hours at a time (XP4 manual).
  3. Turn the key and power on, then ride gently and note how long until E006 returns.
  4. If the charger light never lights, check the cord and outlet. If it still stays dark, stop and contact Lectric.
  5. If the light stays red all night, stop and contact Lectric, since that points to the battery.
  6. If you have a second Lectric charger for your model, it can show whether the charger or the battery is at fault. See check your charger.

Fix options

Charge fully and change charging habits (easy)

Most E006 codes end here. Follow e-bike battery care to slow wear.

Replace the charger (easy, through Lectric)

If a known good charger fills the battery and yours doesn't, replace the charger. Lectric sells chargers on its parts page. Use only a charger Lectric lists for your bike.

Replace the battery (easy to fit, bought through Lectric)

A battery that won't hold a charge is replaced as a whole pack. Lectric lists spare batteries for the XP4, XPeak and XP Trike 2 on its parts page. Confirm the right pack for your exact model with support first.

When to get a pro

Get help if the battery is swollen, cracked, hot, smells odd or got soaked, or if E006 continues after a full charge. Contact Lectric support first (service network page). See battery won't charge, battery drains fast and when to call a pro.
