LightningBolt Machine Battery


CLASS III SYMBOLA Class III appliance is designed to be supplied from a separate/safety extralow voltage (SELV) power source. The voltage from a SELV supply is low enough that under normal conditions a person can safely come into contact with it, without the risk of electrical shock. The extra safety features built into Class I and Class II appliances are, therefore, not required. For medical devices, compliance with Class III is not considered sufficient protection, and further more-stringent regulations apply to such equipment.

For your safety, this power unit has been shipped disabled. To activate, plug into a USB-C power source and charge completely until the LED light remains solid green. It’s important to charge for a minimum of 3 hours prior to first use.

LED Indicator:Single blink = Whole Value Double blink = Half Increment Ex. Solid green indicates 10V  Flashing green indicates 10.5VBattery Level Check:Press and hold power button till white. On release color = %Note:LED flashes while battery charges. Once < 15% is reached, a red light will blink alternately with voltage.

Automatic Fault Detection:Overcharge Detection (OVP)Over-Discharge Detection (UVP)Charge Overcurrent Detection (OCC)Discharge Overcurrent Detection (OCD)Load Short-Circuit Detection (SCP)

Menu Modes:Press and hold power button.Bluetooth on:Hold the power button until the LED indicator turns blue, then release the power button.Bluetooth off:Hold the power button until the LED indicator turns yellow, then release the power button.Hard shut off:Hold the power button until the LED indicator is red, battery is now disabled.To re-activate the battery, plug into any USB-C power source.Device reset: 


With this feature you’ll be able to control the amount of “give” or resistance of the needle upon impact with the skin. This enables the artist to take advantage of the softness or hardness of hit to achieve specific results. 0 no effect, 5 maximum amount of E-give.

SETTING E-GIVE:There are 6 settings for E-give, 0 through 5. Change the setting by swipping down and up on the bars. The higher the setting the higher the amount of give. 0 = no give, 5 = maximum give.E-GIVE INDICATOR:The number displayed is the current E-give setting



While voltage is a parameter that will vary from artist to artist, the LightningBolt has been tested to operate at a minimum voltage of around 5-Volts with a maximum voltage of 12-Volts.Depending on the type of needle configuration, or brand you use, feel free to adjust the voltage to obtain the desired performance.NOTE: Some machines require a minimum voltage to operate correctly, please check your machine manufacturer’s requirements.
