USER MANUAL LIPO BALANCER CHARGER 2-3S GRAUPNER

General Safety Notes Introduction Please study these instructions, reading them completely and attentively, before you use the unit for the first time. This will guarantee that you will be able to exploit all the facilities of your new battery charger. The warnings and safety notes are particularly important. Please store these instructions in a safe place, and be sure to pass them on to the new owner if you ever dispose of the charger. In purchasing the LiPo BALANCER CHARGER 2 - 3S you have acquired a mature product with an excellent performance. It incorporates the latest semi-conductor technology, controlled by a highperformance RISC micro-processor, to provide superior charging characteristics combined with simple operation and optimum reliability. These features can normally be expected only from much more expensive units. The LiPo BALANCER CHARGER 2 - 3S represents a reliable method of charging two or three Lithium-Polymer cells. The battery balancer connector must be plugged in the right Output for 2S or 3S. Note It is important always to observe the charging instructions supplied by the battery manufacturer, and to keep to the recommended charge currents and times. Do not fast-charge batteries unless the manufacturer states expressly that they are suitable for the high currents which flow during these processes. Rechargeable batteries generally - and LithiumPolymer cells in particular - are sensitive and easily damaged. It is therefore essential to supervise the whole of the charge process. Warnings and safety notes

• This product isn‘t designed for use by children under the age of 14, it isn‘t a toy! This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
• Protect the charger from dust, damp, rain, heat (e.g. direct sunshine) and vibration. It should only be operated in dry indoor conditions.
• Do not open the charger or the power supply by yourselve!

• The case slots serve to cool the charger, and must not be covered or enclosed; set up the charger with space round it, so that cooling air can circulate unhindered.
• The charger is designed to be powered by a 12 V car battery (11 - 16 V DC) or with the power supply to a mains socket (100 ~ 240 V AC). Select the appropriate power input. If the 100~240V AC input is selected, for pluggable equipement like power supply, the socket-outlet shall be installed near the charger and shall be easily accessible. If the input voltage of the charger is over 18V DC, this will damage the charger and can cause even fire. Danger!
• Never connect the charger to both power sources simultaneously, and never connect an AC voltage to the DC voltage input. Do not modify the charger in any way.
• 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. Keep all inflammable and volatile materials well away from the charging area. Provide good ventilation.
• Connect the charger directly to the car battery using the original cables and connectors supplied. The car’s engine must be stopped all the time the LiPo BALANCER CHARGER 2 - 3S is connected to the car’s battery. Do not recharge the car battery at any time when the LiPo BALANCER CHARGER 2 - 3S is connected to it.
• The charge output sockets and connecting leads must not be modified, and must not be inter-connected in any way. There is a danger of short-circuit between the charge outputs and the vehicle’s bodywork when the charger is connected to the car battery. The charge leads and connecting leads must not be coiled up when the charger is in use. Avoid short-circuiting the charge output or the model battery with the car bodywork. For this reason the charger must never be placed directly on the vehicle’s bodywork.
• Never leave the charger running or connected to the car battery unsupervised.
• Only one battery may be connected to the charger for charging at any one time.
• The only types of battery which may safely be connected to the charger are: Lithium-Polymer packs consisting of two to three cells.
• Never charge 2cells and 3 cells at the same time! General Operating Information
• To avoid short-circuits between the crocodile plugs fitted to the charger lead, please always connect the charger lead to the charger first, and only then to the battery to be charged. Reverse the sequence when disconnecting. Check before using the charger Before charging please check the following points: are all connections firm and secure, i.e. no intermittent contacts? Please bear in mind that it can be dangerous to fast-charge batteries. For example, if there is a brief interruption due to an intermittent contact, the result is inevitably a malfunction such as a restart of the charge process, or an incorrect cellcount detection, which could result in the pack being massively overcharged. Charging batteries When a battery is charged, electrical current is fed into it at the rate of max. 1.1 A. The charger automatically adjusts the charge current, and reduces it when the final charge voltage is reached.
• Batteries must always be supervised when on charge.
• Batteries MUST be placed on a fire-proof surface for charging.
• Never attempt to recharge defective or inflated Lithium cells!
• Connect the battery to be charged using genuine GRAUPNER-EH balancer connectors for LithiumPolymer cells.
• Ensure that all connectors and terminal clamps make good, sound contact. For example, if there is a brief interruption due to an intermittent contact, the result is inevitably a malfunction such as a restart of the charge process, which would result in the pack being massively overcharged. Lithium-Polymer cells This charge program is only suitable for charging Lithium-Polymer batteries with a nominal cell voltage of 3.7 V. The main outstanding feature of Lithium batteries is their much higher capacity compared to other battery types. This is an important advantage, but it is balanced by the requirement to handle the batteries differently, especially with respect to charging and discharging, if the danger of using them is to be minimised. There are important basic rules governing the handling of these cells, and they must be observed at all times. For additional information and safety notes please study the battery manufacturer’s published specifications. The fundamental rule is that Lithium-based batteries may ONLY be charged using special chargers which are designed and set for the actual battery type (final charge voltage, capacity). The method of charging these batteries is different to the one employed with Ni-Cd or Ni-MH batteries, and is based on what is known as a constant current / constant voltage process. The charge current required varies according to the battery capacity, and is set automatically by the charger. Lithium batteries are generally charged at 1 - 2 C (1 C charge current = capacity charge current. Example: with a battery capacity of, say, 1500 mAh the corresponding 1 C charge rate is 1500 mA, or 1.5 A). On this charger the charge current is set to max. 1.1 A. Once the battery reaches the final charge voltage appropriate to the specific battery type, the charger automatically reduces the charge current in order to prevent the final charge voltage being exceeded. The charger does also balance the voltage of the single cells, if it‘s different, so this increases safety and the life time of the battery.
