Battery recommendation: please use (with protective electronics) Li-Ion batteries
This accumulator is distinguished by its simple technical design, which, however, eliminates the usual disadvantages of a mechanical start-up button, such as relatively high on-load resistance and increased wear at large currents.
The scarab button switches only a control signal for an "output stage" with a resistance of less than 0.002Ω.
As a result, this accumulator can switch currents up to 30 A. Use only protected batteries (see safety instructions)!
High currents (> 10A), however, require EVERY battery extremely (observe the safety regulations of the battery manufacturer).
The contacts and the internal resistance of the battery (poor quality or end of life) can then form a higher resistance than the winding, so that they also convert more power into heat (as with a short circuit)!
They measure a CLEAR lower voltage at the evaporator than at idle (without evaporator), even when the battery is full.
This voltage loss occurs at the ACKU internal resistance or at the contact points and NOT at the electronics (see voltage loss of the electronics in the specifications)!
If you insert the battery correctly (with the positive pole first) and the battery cap FEST (without force), you can activate the evaporator with the button.
Through an opening in the button, a green LED lights up more or less intensively depending on the battery level, until it fades at approx. 3V.
Attention: Another operation is possible! They may damage or destroy the battery (see the specifications of the battery manufacturer)!
If the LED does not light up, the battery is empty or defective, or there is a short circuit in the evaporator!
If the LED lights up red (additionally vibrating the battery carrier and maximum current flow to the evaporator), the battery is inserted in the wrong direction!
In this case, REMOVE THE BATTERY IMMEDIATELY and insert it properly.
For short-term protection against unintentional switching on, pull the button slightly upwards and turn it counter-clockwise (to the left) until it locks! Correspondingly reversed during restart.
This is NOT ALTERNATIVE TO REMOVING THE BATTERY FROM THE DEVICE during prolonged non-use!
You have to consider the possibility of a defect or a malfunction and its consequences with every technical device!
Prevent any penetration of liquids through the probe!
Warning: This device does not take any notice of the winding resistance or internal resistance of the battery!
In case of non-observance of the instructions or ignorance of Ohm's law, this device can destroy the winding and / or the ACCUMULATOR IMMEDIATELY (especially with polarity reversal)!
Example calculations for winding resistors and the power range of a conventional battery:
Battery voltage (fully charged) with 4.2V; Winding with 1Ω
=> 4.2V / 1Ω = 4.2A => 4.2V * 4.2A = 17.6W
Battery voltage (discharge) with 3.0V; Winding with 1Ω
=> 3.0V / 1Ω = 3.0A => 3.0V * 3.0A = 9.0W
Use only protected batteries!
SPECIFICATIONS
Operation with ONE protected Li-Ion battery with flat (flat-top) or raised (button-top) positive pole.
Max. Operating voltage: 4.5V
Min. Winding resistance: 0.13Ω
Max. Permissible operating current: 30A - Danger to the battery
Max. Transient: 50A (70A) - Short circuit of the battery
Residual current: <0.1mA
Voltage loss (volt-drop) of the electronics without contact transition resistors and internal resistance of the battery:
Voltage loss @ 10A: approx. 0.02V
Voltage loss @ 20A: approx. 0.04V
Voltage loss @ 30A: approx. 0.07V
Attention : When using a KICK , the height of the winding resistor must be observed since the maximum voltage of 4.5 V is not to be exceeded!
For the calculation of the max. The following formula applies:
4.5 V to the square = 20.25 V² divided by the set power in watts results in the max. Winding resistance.
Examples:
10 watts: 20.25 volts: 10 watts = 2.02 ohms (max)
12 watts: 20.25 volts: 12 watts = 1.68 ohms (max)
15 watts: 20.25 volts: 15 watts = 1.35 ohms (max)
