Taifun power source
Operation manual
The quality of the battery plays the most important role in the operation of the Taifun. The battery should be able
to provide a current of at least 8 amps (A)!
The internal resistance of the battery should be as small as possible, which is usually seen by a high output cur-
rent capability of the battery. A battery that can provide 15 amps according to the manufacturer usually has a
lower internal resistance than a battery that can provide "only" 8 or 10 amps.
You recognize the quality
(or condition with respect to charge and aging)
of the battery by the fact that its
voltage does not vary a lot between idle and load operation. Of course the battery should maintain the voltage
for a long time.
Common Example (the voltages do NOT need to match your values shown in the menu!):
No-load voltage n = 3.8 volt (V)
voltage with load (e.g. at a output power of 15 watts) b = 3.4 volt
Spread = 0.4 volt
The Spread (of 0.4 volt) is an indication for the battery under
exactly the current
load!
Generally: The lower the difference, the lower the internal resistance of the battery. This on the premise of an op-
timal contact between battery and circuit board. The better the contact, the lower the measured voltage
drop!
When the voltage difference increases between idle and load, check the following:
1. Is the battery charged sufficiently?
2. Are the contacts of the screw cap and the battery clean?
3. Do you have the screw cap SUFFICIENTLY tightened (without violence)?
The best possible contact between battery and battery carrier is of central importance and during the develop-
ment of the device a top priority!
If necessary, replace the battery and clean the contacts!
