Cold weather can change battery output and range. The important charging step is to let a cold pack return naturally to the recommended charging temperature. Keep model-specific storage voltages tied to the battery they describe.
Winter Riding And Charging
An ONYX can be ridden in winter conditions without damaging the bike, but cold temperatures will temporarily reduce battery output and range.
That loss is usually temporary. Once the battery warms back up, normal performance returns.
| Winter Condition | Practical Result |
|---|---|
| Below 32°F | 10-15% range loss |
| Cold battery | Reduced output until warmed |
| Overnight freezing | Bring battery indoors |
| Frozen battery | Do not charge |
Cold-weather riding is fine. The bigger issue is what happens afterward. If the battery has been sitting in freezing conditions, bring it indoors and allow it to warm up before connecting a charger.
Winter Storage Habits
Winter storage is mostly about avoiding unnecessary stress.
- store the battery indoors overnight
- do not leave the bike unused in freezing weather for more than four hours
- avoid charging the pack until it has warmed naturally
- do not use space heaters, heated blankets, or similar direct external heat sources on the battery
Minor battery self-discharge during storage is normal.
Winter Storage Details
If the bike will sit for more than a month, disconnect the battery from the bike before storage.
For longer storage, keep the battery around 60-80% charge. On a 41Ah battery, that is about 74V. A battery stored around 74V may slowly drift to about 73.5V over roughly three months, which is normal.
Avoid storing the battery outside the recommended storage range of 50°F-77°F (10°C-25°C) when possible. Cold storage below 32°F can reduce performance and increase stress on the pack when it is returned to service.
Let the battery return to a safe operating temperature gradually before charging or riding.
