8.4.2 LiPo batteries
After the flight, the LiPo flight battery must be disconnected
from the »Xtreme.
Lithium is a highly reactive chemical element with a
high energy density. In the case of overcharging, the
LiPo rechargeable battery packs might catch fire or even
explode. Therefore, LiPo rechargeable battery packs must
always be put on a fire-proof surface for charging and the
charging process must be supervised.
