The result is the expected battery life in hours. mAh ratings for common battery types are below:įinally, divide the battery mAh value by the LED strip mA value. Then, find the mAh rating from the battery. If is provided in watts (W), divide the number by the voltage (e.g. If it is provided in A (Amps), multiply the number by 1000 to convert to milliamps (mA). It is usually expressed in watts per foot or meter. This is usually provided in a specification sheet for the LED strip product. This value indicates the number of hours the battery can provide a certain electrical current (mA) or power (W) before it runs out of charge.Ī bit of simple math is needed to calculate how long a fully charged battery can be used to power an LED strip.įirst, determine the power draw of the LED strip in watts. If you want to use standard AA batteries, you can use a battery holder that creates a 12V voltage from 8x 1.5V AA batteries.īattery capacity is typically calculated in milliamp hours, abbreviated mAh, or watt-hours, abbreviated Wh. Unless you have a specific situation that requires something else, 12V should work just fine. The most common LED strip and battery voltage combination is 12V DC. Conversely, under voltage is not usually harmful to the LEDs, but can result in reduced brightness or no illumination at all. The main thing to be aware of is that a battery providing a voltage level above the LED strip voltage spec can result in damage to the LEDs. The primary requirements for powering an LED strip from a battery are:ġ) LED strip voltage must match battery output voltageĢ) Battery supply capacity should be sufficient for your needsģ) Connectivity method between LED strip and battery pack must match Voltage Selection See below for some general tips and guidelines for finding a compatible pairing. The options for connecting a battery to an LED strip are by no means limited to the method and accessories we tested. Waveform's FilmGrade dimmer connects between the battery pack and LED strip, acting like a "valve" that reduces brightness without any flicker or change in color.Īs expected, battery lifetime improves in direct relation to the dimmer setting. For this, we use a PWM dimmer which fits right into the low voltage DC system. We often find that the brightness of the LED strip can be reduced in certain scenarios. When not being used, we recommend unplugging the LED strip completely as a precaution. To temporarily power off, simply click on the power button on the battery pack.
This translates to approximately 1 hour based on the FilmGrade LED strip power spec of 90W per reel. The official battery capacity specification provided by RAVPower indicates 85Wh.

From a full charge, the battery pack is able to provide about a full hour of continuous illumination of an entire reel.
