If a lithium rechargeable battery with balancer plug is connected to
the charger, you can switch to the display of the individual cell volt-
ages by pushing the button "INC", see gure on the right.
Briey push the button "START/ENTER" for the charger to return to the normal display.
Important!
Only a battery pack with exactly the same voltage for each cell provides the maximum performance and
service life for a model airplane/vehicle.
Variations in the quality of the materials used and the internal structure of multiple-cell lithium battery
packs mean that the cells may have different voltages once discharged.
Charging such a rechargeable lithium battery without balancer will quickly cause large differences of cell
voltage. This not only shortens the operating life (as one cell may have a very low voltage), but also dam-
ages the rechargeable battery as a result of a total discharge.
When charging a rechargeable lithium battery with different cell voltages without a balancer, there is the
risk of overcharging one cell.
Example:
A dual-cell LiPo battery pack charged without the use of a balancer appears to have a voltage of 8.4 V and thus ap-
pears to be fully charged. The individual cells, however, have a voltage of 4.5 V and 3.9 V (one cell is dangerously
overcharged, the other half discharged).
A cell overcharged in this way may leak, expand or, in a worst case scenario, catch re or explode!
When this LiPo rechargeable battery is, e.g., used in a model airplane, the ight time will be very short because the
voltage of the half-discharged cell will break down quickly and the rechargeable battery will stop supplying power.
If your lithium battery has a balancer connection, it must always be connected to the charger via the
balancer plug in addition to the two regular rechargeable battery connections (plus/+ and minus/-); always
use the charge programme "BALANCE" then instead of the charge programme "CHARGE".
