ONYX Battery Safety
Keep an eye on your battery temps with the BMS app when pushing your bike hard. 135°F is your safety buffe-go beyond that, and the BMS will pull the plug on your ride until the battery cools below 135°F.
Fardriver Controller Safety
Never tune a Fardriver controller to pull more than 100A from the ONYX 41Ah battery. Pushing it to 200A overwhelms the battery, heating it up dangerously fast-a disaster waiting to happen. Throw in a steep hill or sloppy throttling, and you might turn your ride into a bonfire before the BMS can even react.
Stock Controller Safety
From 2018-2024, stock ONYX controller settings were limited to 50A, which both the 23Ah and 41Ah batteries could handle. Sicko Mode at 100A pushes the 23Ah battery beyond its 70A limit, causing premature wear-but thanks to its robust BMS, temperatures stayed in check. The 41Ah battery could handle it but still experienced some strain over time.
Battery Temperature
The maximum temperature for all stock and aftermarket cells used in an ONYX is 176°F, but most BMS units will shut the battery down if it heats up too quickly past 140°F. Before turning back on, the BMS requires it to cool down to 135°F.
Discharge Temperature
Keep it under 125°F for discharging. The trigger field is the temperature where the BMS cuts off charging or discharging if the battery heats up too fast. Even after letting off the throttle or shutting down, heat can keep rising-especially on hot days-since tightly packed cells trap heat like an oven. The release field is when the BMS allows charging and discharging to resume.
| Battery | Trigger | Release |
|---|---|---|
| ONYX 45AH | 140°F | 135°F |
| ONYX 41AH | 158°F | 140°F |
| AMORGE | 140°F | 135°F |
Charge Temperature
When it comes to charging, keep it under 113°F. Do not fast charge a scorching-hot battery that’s internally at 135°F with 10A on a blazing summer day. Let it chill for 30 minutes to an hour until your BMS app shows it’s cooled to 110°F.
| Battery | Trigger | Release |
|---|---|---|
| ONYX 45AH | 140°F | 135°F |
| ONYX 41AH | 149°F | 131°F |
| AMORGE | 135°F | 130°F |
UL Lithium Case Safety Standards
According to UL lithium battery standards and regulations, all lithium batteries must be housed in an external protective case. Batteries without a proper external metal enclosure are vulnerable to physical damage or compromise, posing significant safety risks. This makes a secure metal casing an essential component for safe operation.
The protective case safeguards the battery from punctures and deformation, provides structural rigidity, and features a handle for easy and secure transportation.
ONYX Battery Storage
Explore the detailed post on year-round battery storage to learn the best practices for maintaining and protecting your ONYX Motors battery. It covers what to do-and what to avoid-to ensure your battery stays in optimal condition throughout the year.
ONYX 45AH Battery Safety
ONYX Motors, prioritize safety by providing customers with durable external protective metal cases for their batteries. ONYX Motors exemplifies this commitment by securely housing their 45Ah battery in a sturdy metal enclosure, as shown in product images.
ONYX Motors achieved significant battery cost reductions while enhancing both internal and external build design, prioritizing safety and performance. The price of their stock battery was reduced to $949, accompanied by substantial upgrades. The battery capacity increased from 41Ah to 45Ah, the discharge improved from 100 amps to 180 amps. These advancements deliver enhanced performance while making high-quality upgrades more affordable and accessible for riders.
Safer Aftermarket Batteries
In 2024, the ONYX community partnered with various aftermarket battery builders to create batteries with higher continuous discharge rates, improved thermal performance, enhanced quality, and greater safety. These collaborative efforts resulted in significant advancements, including complete internal redesigns, advanced battery management systems, thicker copper gauge, thicker busbars, higher-gauge wiring, cell spacers, thermal silicone, and durable metal protective cases, as illustrated in the image below.
Outlet Timer with Remote Control
While you can leave your charger plugged in overnight, it’s always a good idea to use an outlet timer-just in case you forget!
