Li-Po batteries

General guidelines for using Li-Po batteries

• Purchasing: only purchase batteries from reputable manufacturers or suppliers.
• Inspect before use: carefully inspect all batteries for damage before use. Do not use damaged or bulging batteries; these should be disposed of promptly.
• Avoid punctures: keep batteries away from sharp objects and avoid any actions that could puncture the casing.
• Correct polarity: ensure correct polarity when connecting batteries; reversing polarities can be dangerous.
• Do not mix batteries: avoid mixing different battery types, or combining new and old batteries.
• Li-Po battery disposal: Li-Po batteries should be disposed of once they can no longer hold a substantial charge. Contact the lab manager for proper disposal procedures.

Charging

• Follow the original manufacturers charging instructions.
• Always charge batteries inside a fire-resistant container.
• Make sure that the charger has sensed the battery correctly.
• Do not over-charge or excessively discharge batteries.

Storage

• Remove batteries from devices for long-term storage.
• Fully charged Li-Po batteries must be stored inside the flammable storage cabinet in a fire resistant Li-Po safety bag/box.
• When not using the Li-Po battery for more than 14 days, charge the battery using the storage setting to properly maintain per-cell voltage at the storage value (3.7-3.8 V).

In case of potential safety issue

• Perform a hazard assessment (including failure modes).
• Use heat-protective gloves and safety glasses/goggles to remove the battery from charging (if safe). Try removing the drone from the foam mats if problems happened during tests.
• Don’t poke or disturb the battery.
• Notify the lab manager about all incidents.
