This short video is not recent, but it demonstrates the explosive and fire potential of LIPOs overcharged beyond their designed capacity. Overcharging is not the only way LIPOs can fail.
Manufacturing defects, internal insulator leaks, can also cause a LIPO to fail EVEN THOUGH it has been properly used and maintained. Multi-cell LIPOs, like the 4S types used in the Typhoon H and H520, typically have more potential for failure than single cell types such as the ST16 battery.
LIPOs are safe when handled correctly, charged, used, and stored according to the manufacturer's recommendations. If you are new to LIPOs, know that they are not like the usual off-the-shelf batteries. Take time to study and understand how to handle and use them; keep them in fireproof containers out of temperature extremes.
