Question: How do I tell if a LiPo pack is unsafe to use?
Answer: To determine if a LiPo battery pack is unsafe, first look for physical damage such as swelling, puffing, punctures, or cracks on the casing. A swollen pack is a clear sign it should be discarded. Next, check for any unusual smells or leaks. Use a LiPo voltage checker to confirm each cell's voltage; cells below 3.0V or with large voltage differences between them indicate problems. When charging, monitor the pack closely—excessive heat (above 50°C) or failure to reach full charge can indicate faults. Avoid using packs that have been involved in crashes or stored improperly for long periods. Always store LiPos in a fireproof container and never charge unattended. If you notice any of these warning signs, safely dispose of the pack at a battery recycling centre. Regular inspection and careful handling are key to safe LiPo use.
