-The battery we use is of the type LiPo (Lithium-Polymer). They are currently the most popular battery type for R/C use. The LiPo is hoverer not the safest chemistry and should be handled with care. Failing to do so could make it catch on fire. It is also sensitive to under/over charge, to high discharge/shortage, heat and more. What it is good at however compensates for all these shortcomings as it has among the best power to weight ratios and discharge currents. +The battery we use is of the type LiPo (Lithium-Polymer).
