Lilon/LiPo Compact Plug-In Charger for 2 (LiPo-charger 2) or 3 (LiPo-charger 3)

Lilon/LiPo cells, with a max. charging current of 0.9A at an affordable price

If you wish to fully exploit all the features of your new charger you should read the following description carefully and completely before using it. Please pay special attention to the warnings and safety instructions. You want to keep this manual in a safe place and eventually pass it on to a potential future user of the charger. By purchasing the LiPo charger 2/3 you have come into possession of an elaborate product featuring outstanding qualities. The use of the most recent semi-conductor technology has made it possible to obtain those superb charging characteristics, simple handling, and an optimum of reliability that you will normally find only with devices of a higher price class. The LiPo charger 2/3 can charge 2 or 3 Lilon or Lithium polymer cells.

Please note:

The charging instructions of the battery producers, as well as the charge currents and charging time, should always be respected. Only the batteries which are expressedly adapted to the use of these high currents may be quick-charged.

LiPo cells are highly sensible devices. Therefore they may only be charged when a permanent surveillance of the charging process is assured.

Warnings and Safety Instructions:

• Protect the charger from dust, humidity, rain, heat (e.g. direct exposition to sunshine) and vibrations. It should only be used in a dry environment!

• The charger is adapted for mains voltages of 100-240 V/AC Don't carry out any modifications on the charger. During the charging process the battery must be placed on a non-inflammable, heat-resist tent ad electrically neutral surface. Never place the system on the seats of car, on a carpet, or in similar places! Keep inflammable objects away from the charging system. Provide good ventilation.

• Don't alter or interconnect the charger output sockets or the output connectors. The charging leads shouldn't be coiled up during charging!

• Avoid any short-circuiting of the charger output leads or the batteries.
• Never leave the charger unattended while it is connected to the mains.
• Connect only one battery at a time to the charger output sockets.
• Connect only batteries of 2-3 Lithium Polymer cells to the charger.
• This product isn't designed for use by children under the age of 14, it isn't a toy!

Check before charging:

Are all connections in perfect order, or are there any loose contacts?

Don't forget that quick charging of batteries may be dangerous.

Charging a battery:

While charging, a certain amount of current is being fed into the battery. The maximum charge current for the LiPo charger 2/3 is of 0.9A.

• Batteries should always be attended to while charging them!
• Charge batteries only on a fire-proof support!
• Flawed or distended batteries may by no means be charged!
• The battery to be charged should be connected with an original plug for GRAUPNER LiPo batteries.
• Make sure that all connectors, plugs, and sockets have a good and safe contact. Any interruptions in the charging process, even short ones, may lead to a new start of the charging process, und thus totally overcharge the battery.

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 advantage, 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 current. 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.

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.

Charge mode:

Connect the red BEC plug of your LiPo Balancer Plus #3064 to the output lead of the LiPo charger 2/3.

Then you should connect the white Graupner Balancer plug of the battery to the OUTPUT of the LiPo Balancer Plus, and then the red battery connector to the BATTERY input of the LiPo Balancer Plus, left-aligned.

Now you're ready to connect the LiPo Balancer Plus by pressing the MODE/RESET key until the status LED begins to flash.

This charging procedure obtains that the battery will be fully (100%) and carefully charged

During the charging process the red LED of the LiPo charger 2/3 will be lit.

Battery charged:

As soon as the battery has reached its full (100%) capacity the device will be automatically switched off. This will be signalled by the fading off of the red LED. The green LED will be lit.

It is completely normal that the battery pack doesn't warm up, or at least only marginally, since the LiPo charger 2/3 automatically reduces the charge current by the end of the charging process.
