Question: How do I tell if a LiPo pack is unsafe to use?
Answer: To check if a LiPo battery pack is unsafe, first inspect the pack visually. Look for any swelling, puffing, or bulging—this is a clear sign the cells are damaged and the battery is unsafe. Check for any physical damage like punctures, tears in the outer wrapping, or corrosion on the terminals. Next, measure the voltage of each cell using a LiPo cell checker or a multimeter; any cell below 3.0V or significantly out of balance with others indicates a problem. Avoid using packs that have been stored fully discharged or left unused for long periods without maintenance. Also, if the battery gets excessively hot during charging or use, or if it emits a strange smell, stop using it immediately. Always use a proper LiPo charger and never charge unattended. If you notice any of these signs, safely dispose of the battery at a local recycling centre that accepts lithium batteries. Safety first—never risk using a compromised LiPo pack.
