D) Fast Charge ("Fast Chg"); E) Storing Batteries ("Storage") - VOLTCRAFT UCT 100-6 Bedienungsanleitung

In addition, there is the danger of overcharging when charging such different cells (with
different voltage) without the balancer: The maximum admissible voltage of a LiPo cell of
approx. 4.2V (+/- 1%) is exceeded (Li-ion and LiFe data, see chapter 7).
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 a worst scenario, catch fire or
explode!
If your LiPo battery has a balancer connection, the charging program "BALANCE"
should always be used.
If your "LiFe" or "LiIon" pack also has a balancer connection, the above information
applies, only the voltage values differ, see chapter 7.

d) Fast charge ("FAST CHG")

When charging lithium battery, the charge current lowers significantly as the battery gets charged.
This increases the charging time. With fast charging, a higher charge current is adopted. However,
this reduces the capacity because the charging process will be terminated earlier due to the safety
cuoff in the charger.
This means that the lithium battery cannot be fully charged using the quick charge function. Only
approximately 90% of the capacity can be achieved when compared with the normal charging mode.
Use the fast charging mode when the batteries are to be charged as soon as possible.
The procedure of setting the charge current and the voltage/cell count is the same as that of normal
charge process (see chapter 11. b).

e) Storing batteries ("STORAGE")

This function can be used to set the battery to their ideal voltage level suited for storage (LiPo = 3.85V,
LiIon = 3.75V, LiFe = 3.3V).
Depending on the original cell voltage, the battery is either charged or discharged. With a multi-cell
battery pack, a balancer connection is necessary.
The procedure of setting the current and the voltage/cell count is the same as with the normal charge
process (see chapter 11. b).
The set current is used for charging/discharging.
