Working with electricity can be dangerous, and it’s crucial to prioritise safety when dealing with VESC controllers, batteries, and other electrical components. High voltage battery packs used in VESC builds can cause serious injury or even death if mishandled.
DISCLAIMER: The VESC Bible is currently being republished and rewritten to encompass all necessary beginner guides. All guides with a beta tag are still preliminary and need to be vetted and reviewed by VESC experts.
Potential Hazards
- Electric Shock: Contact with high voltage can lead to severe electric shock, causing burns, muscle contractions, and even heart failure.
- Battery Fires: Lithium-ion batteries contain flammable electrolytes and can ignite or explode if damaged, overcharged, or shorted.
- Burns: Soldering irons and other tools used in VESC builds can reach high temperatures and cause burns if not handled carefully.
- Component Damage: Incorrect wiring or handling of electrical components can lead to damage, potentially causing malfunction or safety hazards.
General Safety Guidelines
Handling Batteries
- Wear appropriate personal protective equipment (PPE), including safety glasses and insulated gloves, when handling batteries.
- Never work on a live battery. Disconnect the battery from all circuits before performing any work.
- Inspect batteries for damage before use. Look for signs of swelling, punctures, or leaks.
- Use a battery charger specifically designed for the type and voltage of your battery pack.
- Charge batteries in a well-ventilated area away from flammable materials.
- Never leave a charging battery unattended.
- Store batteries in a cool, dry place away from direct sunlight and heat sources.
- Dispose of batteries properly according to local regulations.
Soldering
- Use a soldering iron with adjustable temperature control and select the appropriate temperature for the components being soldered.
- Ensure proper ventilation when soldering, as fumes can be harmful.
- Wear safety glasses to protect your eyes from solder splatter.
- Never touch the tip of a hot soldering iron.
- Use a soldering iron stand to safely hold the iron when not in use.
Working with Electrical Components
- Always disconnect power before working on any electrical circuit.
- Use a multimeter to check for voltage and continuity before connecting components.
- Double-check all connections to ensure they are secure and properly insulated.
- Use heat shrink tubing or electrical tape to insulate exposed wires and connections.
- If unsure about any aspect of wiring or component handling, consult resources like PEV.dev, VESCify Discord, or seek assistance from experienced builders. (See our Verified Vendors and Builders section)
Remember, working with electricity demands respect and caution. Taking the necessary precautions can help prevent accidents and ensure a safe and enjoyable VESC building experience.
