C) General Information About How To Charge - VOLTCRAFT VC-1506 Bedienungsanleitung

• Charge LiPo accumulators with a max. charge current of 1C. This means that the charge current
may not exceed the capacity value imprinted on the accumulator (e.g. accumulator capacity
1000mAh, max. charge current 1000mA = 1A).
• With LiFe or LiIon accumulators, you must observe the instructions of the accumulator manufacturer.
• The discharge current must not exceed the value displayed on the accumulator. For example,
if a value of „20C" is printed on the accumulator, the max. discharge current is 20 times the
accumulator's capacity (e.g. accumulator capacity 1000mAh, max. discharge current 20C = 20x
1000mA = 20A).
If these guidelines are not adhered to, the accumulator will overheat, which will lead to the accumu-
lator becoming deformed/swollen or result in an explosion and fire!
• The printed value (e.g „20C") does not generally refer to the constant current, but to the maximum
current that the accumulator is capable of producing in the short-term. The constant current should
not be higher than one half of the given value.
• No cell of a LiPo accumulator may be discharged below 3.0V (LiFe = 2.0V, LiIon = 2.5V), as this will
destroy the accumulator. If the model does not provide protection against total discharge or possess
a visual display indicating a low accumulator, remember to switch off the model in time.

c) general information about how to charge

A certain amount of electric energy is supplied to the battery connected during charging. This quantity is calculated
from the charging current (mA) and the charging period (h). The charging current permitted depends on the battery
type and the battery capacity (mAh) and can be found in the information provided by the manufacturer.
The charging time essentially depends on the type of battery, the charging current set, the battery capacity and the
residual charge. The general rule of thumb is: Capacity of the battery (mAh) / charging current (mA) = charging time
(h). Differences result from the quality of the battery, from the residual charge and from the dissipation power.
Since the battery charger cannot distinguish between the internal resistance of the battery pack, the resistance of
the connecting lead and the contact resistance in the plug connections, it is important to use a suitable cable diame-
ter as well as high-quality (gold) contacts.
Be sure to follow the manufacturer's instructions concerning charging current and charging period, especially for
lithium batteries.
