If in doubt, contact your local waste disposal authorities. Thank you for choosing Velleman! Please read the manual thoroughly before bringing this device into service. If the device was damaged in transit, do not install or use it and contact your dealer.
Keep this manual for future reference. Features The VLE8 is an advanced charger, able to charge, balance and discharge rechargeable batteries. It is microprocessor-controlled just like all the best chargers and will balance the individual cells in your Li-XX batteries. It will charge from 0.1 to 5.0 A and is capable of charging packs up to 6S packs. It features input voltage protection so as not to flatten your car battery at the field and will also storage charge your packs for when you are not using them.
VLE8 Internal, independent lithium battery balancer: The charger features an individual cell-voltage balancer, which makes it unnecessary to use an external balancer for balance charging. Individual cell balancing during discharging: During discharging, the charger will individually monitor and balance each cell in the battery. When the voltage of any cell is deemed abnormal, an error message will be displayed and the discharging process will end automatically.
VLE8 Operation Initial Setup By default, this charger will be set to the user settings when first connecting an 11-18 V load. To alter the parameters, press START/ENTER and change the value with INC/DEC. Store the value by pressing START/ENTER once.

VLE8 Charging a Lithium Battery in Balance Mode This mode balances the voltage of the Li-poly battery cells while charging. In this mode, the battery needs a balance lead to connect to the individual balance port. The battery’s power lead must be connected to the charger’s output.
VLE8 Charging a Lithium Battery in Storage Mode This function is useful when you desire to charge or discharge a battery, which will not be used immediately. This programme is only to be used with following batteries: Li-poly of 3.85 V, Li-ion of 3.75 V and Li-Fe of 3.3 V.

VLE8 The Nickel Programme (NiCd, NiMH) Charging a NiCd/NiMH Battery in Charge Mode This programme will charge your battery using the user-set current. It is recommended to carefully set the upper limit for the charge current to avoid damage by excessive charging. Some batteries with low resistance and capacity can lead to higher current in auto charging mode.

Display Information This charger allows you to inquire various information during charging and discharging. Press DEC to display the user’s setting, press INC to monitor the voltage while the battery is connected to each port of the charger.
VLE8 The display shows the external temperature (only when the temperature probe is being used). The display shows the present input voltage. If the battery is connected via cable, each cell’s voltage is displayed. Warnings and Error Messages In case of an error, this charger will display the cause of error and emit a warning sound.
VLE8 The voltage of one of the cells is too low. Please check the voltage of each cell. The voltage of one of the cells is too high. Please check the voltage of each cell. Wrong connection. Please check the connector and cable.
