Question: How do I tell if a LiPo pack is unsafe to use?
Answer: To check if a LiPo battery pack is unsafe, start by inspecting it visually. Look for any swelling or puffing in the cells, which is a clear sign of damage. Check for any cracks, tears, or punctures in the outer casing. Also, examine the wires and connectors for signs of fraying or burn marks. Next, measure the voltage of each cell using a LiPo-compatible voltage checker or a multimeter; cells with significantly lower voltage than the others may be damaged. Avoid using packs that have been exposed to water or extreme heat. If the pack feels unusually warm or hot after charging or discharging, this indicates a problem. Always store and charge your LiPo packs on a fireproof surface and never ignore any unusual smells or noises. If you notice any of these signs, it’s safest to dispose of the pack properly and replace it. Safety first—damaged LiPos can be hazardous and cause fires.
