ONYX Battery Care
Battery lifespan depends heavily on temperature and charging habits.
This guide covers safe charging temperature ranges, winter and summer storage, and everyday practices that reduce long-term battery stress.
ONYX Battery Diagnostics
This post focuses on diagnosing real-world battery problems, including imbalance, voltage sag, BMS behavior, and determining when a battery requires repair or replacement.
Use this when:
- the bike cuts out under throttle
- the battery feels weak or inconsistent
- voltage behavior does not match expectations
- cell group imbalance is suspected
- the battery overheats or behaves abnormally
ONYX Charging Guide
Charging behavior is one of the most common sources of confusion, especially when comparing 72V and 80V systems.
This guide explains charger compatibility, home charging, EV station charging, J1772 adapters, and the differences between 120V and 240V input.
