User manual GRAUPNER LIPO BALANCER CHARGER 2-3S

[. . . ] 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. [. . . ] 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. Batteries must always be supervised when on charge. 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. 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. Example: with a battery capacity of, say, 1500 mAh the corresponding 1 C charge rate is 1500 mA, or 1. 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. 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 product. For this reason we are obliged to deny all liability for loss, damage or costs which are incurred due to the incompetent or incorrect use and operation of our products, or which are connected with such operation in any way. Components and accessories As manufacturer of this product, the company of GRAUPNER GmbH & Co. KG recommends the use of associated components and accessory products which have been checked and approved by GRAUPNER for their suitability, proper function and safety. In such cases GRAUPNER accepts responsibility for these products on your behalf. We are unable to accept liability for parts or accessories made by other manufacturers, which are not expressly approved by GRAUPNER, as we are not in a position to assess every individual non-Graupner item to decide whether it represents a safety risk or not. [. . . ] Dry cells and rechargeable batteries must be removed from the device and taken separately to a suitable battery disposal centre. 14 Environmental Protection Notes In the case of RC models, the electronic components - such as servos, receivers and speed controllers - must be removed from the model, and taken to an appropriate collection centre for electrical waste. If you don't know the location of your nearest disposal centre, please enquire at your local council office. Conforms with the essential protective requirements as laid down in the directive for harmonising the statutory directives of the member states concerning electro-magnetic interference (89/336/EWG) and LVD (73/23/EG).
