Although there are a wide range of safety mechanisms on the charger, it is
never possible to exclude the possibility of the battery or charger becoming
overheated. The use of charging cables that are too thin or problems with the
contacts may be dangerous!
• Check the temperature of the battery from time to time during the charging
process.
NiMH and NiCd batteries become very hot when using high charge currents,
with temperatures of 50°C or above possible. For this reason, only touch the
battery with care. If the battery overheats, it may be damaged. In this case,
reduce the charge current.
LiPo batteries should generally not get warmer than is safe to touch during
the charging process (charge current max. 1C) A large temperature increase
indicates a defective battery or a defective cell in the battery pack.
• LiPo batteries with more than one cell (battery voltage more than 3.7V) must
almost always be charged with a balancer for reasons of safety. Use the
charging program "LiPo BALANCE CHG".
If the balancer plug does not fit in the appropriate charger socket, the correct
adapter must be used.
