General Operating Information - GRAUPNER LIPO-CHARGER 2 Operating Manual

General Operating Information

Lithium-Polymer cells:
The LiPo charger 2/3 may only be used for
charging LiPo batteries with a nominal cell
voltage of 3.7V/cell.
LiPo batteries are distinguished by their charge
capacity which is significantly higher than with
other types of batteries. However, this advan-
tage, essential as it is in its way on the one
hand, requires a different treatment in view of
the charge / discharge methods and a problem-
free operation. The basic instructions described
here must be observed in all cases. Please refer
to the producer's technical specifications for
further indications and safety rules. Basically,
batteries built on a basis of Lithium may ONLY
be charged using special chargers which are
adapted, with respect to final cut-off voltage and
capacity, to the type of battery to be charged.
In contrast to NiCd or NiMH batteries, LiPo
batteries need the so-called constant current /
constant voltage charging method. The charge
current is a function of the battery's capacity and
will be adjusted automatically by the charger.
LiPo batteries are normally charged with 1-2 C
current, where 1 C is the capacity charge cur-
rent. Example: For a capacity of e.g. 1500mAh
the charge current 1 C is 1500 mA or 1.5 A. The
LiPo charger 2/3 supplies a max. current of 0.9
A, so adjusting isn't necessary and has been
deliberately made redundant. As soon as the
battery's specific charging end voltage has been
reached the charge current will be automatically
reduced in order to prevent that the cut-off
voltage is exceeded.
Liability Exclusion:
As manufacturers, we at GRAUPNER are not in
a position to ensure that you observe the correct
methods of operation when installing, using and
maintaining this charger. For this reason we are
obliged to deny all liability for loss, damage or

shown here, which may be found on the product
itself, in the operating instructions or on the
packaging, indicates that this is the case.
Individual markings indicate which materials
can be recycled and re-used. You can make an
important contribution to the protection of our
common environment by re-using the product,
recycling the basic materials or recycling redun-
dant equipment in other ways. Remove batteries
rom your device and dispose of them at your
local collection point for batteries. If you don't
know the location of your nearest disposal cen-
tre, please enquire at your local council office.
First Operation:
Connect your LiPo charger 2/3 to the mains
(100V-240V AC).
The green LED will now show readiness.
LiPo balancer:
For maximum safety, you should by all means
use a LiPo Balancer Plus, Order No. 3064.
