Owner's manual

The Basetech 80 AC/DC is a multifunctional charger for NiMH/NiCd, LiPo/LiIon/LiFe/LiHv, and lead batteries. It can charge and discharge batteries with a current of 0.1 to 10.0 A (depending on the cell number/rechargeable battery voltage). The maximum charging power is 80 W, and the maximum discharging power is 5 W. It also features a balancer for multiple-cell lithium batteries and can be operated on mains voltage (100 - 240 V/AC, 50/60 Hz) or a stabilized direct voltage of 11 - 18 V/DC.

Rechargeable Battery Notes
Although use of rechargeable batteries in everyday life is a matter of course
today, there are many dangers and problems. In particular, with LiPo/LiIon/
LiFe/LiHv rechargeable batteries with their high energy content (in comparison
with conventional NiCd or NiMH rechargeable batteries), various regulations
must be observed in order to avoid the danger of explosion and re.
For this reason, always ensure that you have read and understood the
following information and safety information when handling rechargeable
batteries.
If the manufacturer of the rechargeable battery has provided any other
information, read it carefully and observe it!

Basetech 80 AC/DC Owner's manual

Type
Owner's manual

The Basetech 80 AC/DC is a multifunctional charger for NiMH/NiCd, LiPo/LiIon/LiFe/LiHv, and lead batteries. It can charge and discharge batteries with a current of 0.1 to 10.0 A (depending on the cell number/rechargeable battery voltage). The maximum charging power is 80 W, and the maximum discharging power is 5 W. It also features a balancer for multiple-cell lithium batteries and can be operated on mains voltage (100 - 240 V/AC, 50/60 Hz) or a stabilized direct voltage of 11 - 18 V/DC.
