[. . . ] warnings and safety notes · Protect the charger from dust, damp, rain, heat (e. The case slots serve to cool the charger, and must not be covered or enclosed; set up the charger with space all around it, so that 6 Safety Notes cooling air can circulate unhindered. ⷠThe charger and the battery to be charged should be set up on a heat-resistant, noninflammable and non-conductive surface before use. Never place the charger directly on a car seat, carpet or similar surface. [. . . ] In contrast to NiCd and NiMH batteries, Lithium batteries have to be charged using what is known as a constant current / constant voltage method. the charge current required is determined by the battery capacity , and the charger detects and sets this automatically. Lithium batteries are usually charged at a charge current of 1 - 2 C, where a charge current of 1 C corresponds to the cell capacity. This makes it unnecessary to set the charge rate, and the charger therefore features no such means of adjustment. Once the specific final charge voltage for the particular battery type is reached, the charger automatically reduces the current in order to prevent the final charge voltage exceeding the permissible maximum value.

Using the charger for the first time START/STOP button OUTPUT 1-4 cells INPUT 11-15V DC Using the charger for the first time Connect your LiPo-Quick-Charger 4 to a 12 V power source of adequate capacity. The ideal power source is a 12 V car battery or other suitable lead-acid battery (Order No. Alternatively a stabilised mains PSU with a rated output of 12 - 14 V and at least 5 A can be used, e. Stand-by mode When you connect the LiPo-Quick-Charger 4 to the power source, the blue LED starts flashing at three-second intervals. Caution: if you press the START/STOP button while the charger is in charge mode, battery charged mode or error mode, the Li-Po Charger 4 reverts to Stand-by mode. charge mode Now connect a suitable genuine GRAUPNER Lithium-Polymer battery pack to the output of the LiPo-Quick-Charger 4. Set the potentiometer following to the desired capacity from 100 to 5000mAh. The charger is able to generate the optimal charge current for your Li-Po battery pack. 8 Using the charger for the first time If you are charging a Lithium-Polymer pack consisting of one to three cells, press the START/STOP button briefly after connecting the battery to the charger. You will hear a loud audible signal to confirm that the button was pressed, and the blue LED (for 1 - 3 cells) lights up; it continues to glow during the charge process. If you are charging a Lithium-Polymer pack consisting of four cells, hold the START/ STOP button pressed in for about two seconds after connecting the battery to the charger. The red LED (for 4 cells) lights up; it continues to glow during the charge process. [. . . ] If the charger does not work at all when connected correctly to a suitable power source, and fails to produce any audible or visual indicators, remember to check the fuse (7. 5 A Blue and red LEDs Reversed polarity protection (input / output) Incorrect cell count Voltage error Circuit break (fuse) Crocodile clips Graupner BEC plug app. Environmental Protection Notes Whenever you see this symbol on a product, in the user instructions or the packaging, it means that you must not dispose of that item, or the electronic components in it, in the ordinary domestic waste when it comes to the end of its useful life.
