Lipo Balance Chg" Charging Program - VOLTCRAFT B5 Bedienungsanleitung

12. "LiPo BALANCE CHG" charging program

This charging program is only suitable for LiPo batteries with a voltage of 3.7V
per cell with a balancer connection. Never try to charge another type of battery
using this charging program.
The charge current to be set is independent of the battery capacity and is usually 1C. However,
you should take the battery manufacturer's instructions into account.
The value "1C" means that the charging current is equivalent to the battery's capacity. As such,
a charge current of 1.8A should be set for a 1800mAh LiPo battery at 1C.
In contrast to the simpler LiPo charging program "LiPo CHARGE", the voltage of each
individual cell is monitored and the charge current is adjusted correspondingly.
Only a LiPo battery 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 LiPo batteries mean that the cells may have different voltages
once discharged.
If such a LiPo battery is charged without the use of a balancer, large differences
in the cell voltages emerge very rapidly. This not only shortens the charge life
(as one cell may give in under the voltage), but also damages the battery as a
result of a total discharge.
There is also the danger of overload when charging different cells (with
different voltages) without a balancer - the maximum permitted voltage of a
LiPo cell of approx. 4.2V (+/- 1%) would be exceeded!
Example:
A dual-cell LiPo battery pack charged without the use of a balancer appears to
have a voltage of 8.4V and thus appears to be fully charged. However, the two
cells have a respective voltage of 4.5V and 3.9V (one cell is dangerously
overloaded, the other is half-empty).
A cell overloaded in this way may leak or, in the worst case scenario,
catch fire or explode!
If your LiPo battery has a balancer connection, the charging program "LiPo
BALANCE CHG" should always be used.
