Battery Safety Guide
Battery Safety Guide
Understanding how your battery works and how to use it safely for years of reliable performance.
Why Battery Safety Matters
Lithium-ion batteries store a significant amount of energy in a compact package. When handled correctly, they are safe, reliable, and long-lasting. When mishandled, they can pose risks including fire, electrical shock, and permanent damage to the battery and your equipment. Reading this guide takes about 10 minutes. It could save your battery, your bike, or your home.
Built-In Safety Features
Your battery includes multiple layers of protection designed to prevent dangerous conditions before they occur.
Battery Management System
The BMS is the brain of your battery. It continuously monitors and protects against:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short circuit protection
- Temperature protection
- Cell balancing
You can check cell voltages, balancing, and temperature on your phone over Bluetooth.
Physical Protection
- Metal-case packs: rigid casing protects cells from impact and puncture
- PVC packs: layered heat-shrink wrap with epoxy insulation boards keeps cells separated and electrically isolated
- Sealed construction: helps keep out dust, debris, and light splashes
Safe Charging Practices
Charging is when your battery is most vulnerable. These rules are not optional.
Always Do
- Use only the included or approved charger, matched to your pack voltage
- Charge on a non-flammable surface (concrete, tile, metal)
- Charge in a well-ventilated area
- Stay nearby while charging
- Allow the battery to cool to room temperature after riding before charging
- Disconnect charger when charging is complete
Never Do
- Charge unattended overnight or while away
- Charge a hot battery immediately after use
- Charge on carpet, bedding, or flammable surfaces
- Cover the battery or charger while charging
- Use a damaged charger, cable, or connector
- Charge a swollen, leaking, or odor-emitting battery
Water & Moisture Exposure
Your battery is designed to withstand light rain and splashes during normal riding. It is not waterproof and should not be submerged or exposed to heavy water.
If your battery gets wet during a ride:
- Wipe it dry as soon as possible
- Check connector ports for moisture before connecting or charging
- Do not charge a wet battery. Allow it to dry completely first
If your battery is submerged or exposed to heavy water:
- Disconnect from the motor system immediately if safe to do so
- Do not attempt to charge it
- Place it in a safe, outdoor location away from flammable materials
- Contact us for assessment. A submerged battery is likely permanently damaged
- Never use a pressure washer or direct hose spray on or near your battery
Physical Damage Assessment
A physically damaged lithium battery is a serious safety risk. Inspect your battery regularly for these signs:
Cracks, dents, or punctures
Swelling or bulging
Frayed or melted cables
Burn marks or discoloration
If you notice any physical damage:
- Stop using the battery immediately
- Do not attempt to charge it
- Place it outdoors in a safe location away from structures and flammable materials
- Contact us with photos for assessment
- Do not attempt to repair physical damage yourself. Opening the battery casing exposes you to high-voltage DC current and voids your warranty
Transport & Travel
When transporting your battery, whether on a car rack, in a vehicle, or when shipping:
- Remove the battery from the bike when transporting on a rack whenever possible
- Protect the battery from impact, crushing, and direct sunlight
- Do not leave the battery inside a hot vehicle for extended periods
- Air travel: Lithium batteries of this size are prohibited on passenger aircraft. They must be shipped as cargo under dangerous goods regulations
- If you need to ship your battery, contact us first. Lithium packs must go as dangerous-goods cargo, not as a regular parcel
Emergency Procedures
Know what to do if something goes wrong. These situations are rare but serious.
If a battery becomes unusually hot, emits smoke, or produces an unusual odor:
- If safe, move the battery outdoors to a non-flammable surface away from structures
- Evacuate the area and call emergency services
- Do not inhale fumes. Battery smoke and fumes are toxic
If a battery catches fire:
- Evacuate immediately
- Call emergency services
- Alert anyone nearby
- Do not attempt to extinguish the fire yourself unless you have proper training and equipment
Summary: The Core Rules
1
Use the charger matched to your pack voltage. Never substitute.
2

3
Inspect regularly for physical damage.
4
Never charge a damaged, wet, or hot battery.
5
Store at 40-60% charge in a cool, dry place.
6
If something seems wrong, stop using it and contact us.
