X‑Class 60V: My battery drops from 100 % to 50 % quicklyUpdated 3 hours ago

Why it happens

Voltage drops quickly right after a full charge if the pack is cold, older, or just finished charging.

Test it

1. Charge to 100 %, then let the battery rest (off the charger) for 60 minutes.
2. Check voltage at the charge port or display:
   • > 67 V = normal resting voltage
   • < 67 V = capacity loss (common after ~700 cycles)
3. Ride 2–3 miles and recheck. A gentle drop is normal; a steep drop may mean that the pack is aging.

What to do

• Keep the battery warm (50–70 °F) before rides.
• If range is down > 30 %, schedule a capacity test or replacement.
