Battery Safety & Care

LiPo Battery Parts

All LiPo (Lithium Polymer) batteries have the basic parts same parts

Proper Lipo Battery Handling

LiPo battery handling involves several important protocols to ensure safety and optimal performance:

1. NEVER leave batteries in hot environments or direct sunlight, as it can cause damage.
2. NEVER place batteries where they can short-circuit against other items.
3. NEVER force batteries into drone if they don't fit properly.
4. NEVER disassemble the battery or make contact with both poles simultaneously.
5. ALWAYS ensure batteries are of similar charge when powering a device.
6. ALWAYS keep batteries in a reasonably climate-controlled environment.
7. ALWAYS unplug batteries before handling or holding the device.
8. ALWAYS discontinue use of damaged batteries and dispose/recycle them accordingly.
9. IF electrolyte comes into contact with the skin or eyes, rinse with water and seek medical attention if necessary.
10. In case of ingestion or exposure, seek medical attention immediately.
11. In case of a fire, extinguish it by smothering with sand or using an ABC Fire Extinguisher.

When not in use, store LiPo batteries at approximately 60% of their rated capacity in a room temperature environment. Make sure to cycle the batteries at least once per month to prevent imbalance or over-discharge.

When charging or discharging LiPo batteries, inspect them for any damages or abnormalities before starting the process. Use a balance charging system designed for LiPo cells and avoid overcharging or over-discharging. Do not charge above 4.2V per cell or discharge below 3V per cell. Avoid drawing more power than the pack is rated for and monitor the temperature during use.

Proper disposal of LiPo batteries is essential. They should not be disposed of with regular waste. Instead, take them to designated collection points for recycling to conserve natural resources and protect the environment.

More Battery Safety Rules

A few more important safety rules to note:

ALWAYS...

• Only use the SmartDrone supplied Battery charger
• Users should always charge Batteries in an open area away from flammable materials, liquids and surfaces
• Always charge the battery in an environment with a moderate temperature (55-85°F)
• Allow battery to sit for minimum 1 hour after flight, in room temp before charging
• Users should Always set the charger to the proper cell count and/or voltage
• Users should always set the charge rate to 7.0A

NEVER...

• Never charge Batteries while they are inside the drone battery compartment
• Never charge or use a battery that has been kept in the freezing temperatures cold (below 0°C, 32°F) or if the battery is hot to the touch (above 100° F). Wait until the battery comes to room temperature before charging or using
  • • ALSO NOTE: leaving a battery in extreme temperatures will shorten its lifespan
• Never overcharge batteries over their rated maximum voltage (4.2V/cell for LiPo)
• Never leave charging batteries unattended
• The charger should never be set to charge/Discharge batteries at a rate greater than 1C
• DO NOT alter the charge rate once charging has begun

Lipo Battery Safety - Hazards, Control Measures, First Aid

Lipo batteries have certain hazards and require appropriate control measures to ensure safety:

1. Health Hazards: The internal contents of a lipo battery can be hazardous if exposed. It is important to avoid contact with the substances inside the battery. If exposed, wash your skin, flush your eyes, rinse with and drink water, and seek medical attention if any concerning symptoms occur.
2. Fire Hazards: Lipo batteries are made with highly flammable, combustible, and reactive substances. It is crucial to prevent the battery from overheating, coming into contact with fire, or being ignited. In case of a fire, stand clear, call the fire department, and do not breathe in the fumes. If necessary, use sand to smother the fire or an ABC fire extinguisher. Seek professional help for the disposal of the battery after a fire incident.

It is important to read and understand the Safety Data Sheets (SDS) for lithium (LiCoO2) polymer batteries. These documents provide detailed information on health hazards and control measures specific to the batteries. Refer to the SDS provided by the manufacturer for comprehensive guidance on handling and safety precautions.

Please consult the specific SDS for the lithium (LiCoO2) polymer battery you are using for detailed information on hazards and control measures.

Battery Management

One way to prolong the lifespan of a battery is to understand when and when not to charge it. Leaving batteries at full charge or at a voltage lower than the storage charge can decrease the usable hours. See the table below detailing battery voltage
