Lithium Ion and Lithium Polymer batteries are very sensitive to charge. If they are over charged they tend to overheat dramatically faster/higher than NICAD's or NIMH batteries. They also are very susceptible to internal shorts that can cause the battery to suddenly overheat and explode. But there are no other batteries currently available that offer the power density per weight that the Lithium cells do.
