The PORTAVOLT™ Rechargeable Li-Ion Battery Pack is designed specifically to integrate with our light bars, LED tape light and strip light, or any 12V DC electronic device. This lithium-ion battery is ideal for mobile displays, bicycles and scooters, costumes, crafts and many other portable applications. This quick-charging battery will recharge up to 98% full capacity in only one hour. It features an integrated On/Off switch, LED indicator light and female DC jack for portable plug-in-play installations. This battery will power one of our 20" TRUE FOCUS™ Light Bars for 13 hours.

Each Lithium Ion Battery Pack comes with:

  • 1 x 3.7 x 2.4 x 1.1 in. PORTAVOLT battery box with an integrated On/Off switch
  • 1 x plug-in Adapter:
  • 1 x 24 inch DC extension cable: with 2 male DC plugs

To calculate the battery life: Divide the Battery Capacity in milliamp hours (mAH) by the Fixture Power Consumption in milliamps (mA) to get the Battery Discharge Rate (hours). For example, this battery has a capacity of 3800mAH and is powering 5 feet of tape light rated at 120mA/ft. First, determine the total power consumption by multiplying 120mA x 5ft. = 600mA. Next, divide 3800mAH / 600mA = 6.33 hours. Therefore, the battery will power the fixture for 6.33 hours.

  1. How long will one foot of Flexible LED Light last on a fully charged battery?

    From Guest at 6/3/10 8:20 AM
    One foot of our Flexible LED Light will last approximately 12 hours until the battery will need to be recharged.
  2. I would like to know how long your Rechargeable Li-ion Battery Pack would last powering an LED RGB Strip that is 10 feet in length. This would be for movable displays.

    From Guest at 6/3/10 8:41 AM
    Our Lithium Ion Battery Pack is rated at 1800mAH or 1.8 AH (amp-hours). Our Flexible RGB LED Light consumes 1.25 watts per foot and 12.5 watts for a 10-foot length. 12.5 watts at 12 volts pulls about 1 amp. Since this battery is rated for 1.8 AH (amp-hours), the 10-foot-long Flexible RGB LED Light would last about 1.5 hours.
  3. How long would a 7-foot low output flexible LED be powered on the battery pack?

    From Guest at 6/4/10 7:17 AM
    This battery is rated at 1800mA hours.
  4. would this battery power a heated jacket,thanks

    From Guest at 9/8/10 9:40 PM
    It would, as long as the jacket requires 12VDC power. I recommend you check the mAh supplied by the battery to what would be consumed by the jacket to determine if the battery would be sufficient.
  5. Is there a way to fast charge this battery?

    From Guest at 12/16/10 12:43 PM
    There is no fast charge option for this battery, just the slow charge.
  6. Is the battery included?

    From Guest at 3/9/11 1:26 PM
    Yes. It also includes a charger and cable.
  7. Can the battery be placed into a wooden compartment that is 1.25 high and 6 inches square or will it overheat


    From Guest at 3/15/11 5:03 PM
    Yes, there should be no problem putting this is a housing.
  8. Can the battery be used whilst being charged in order to avoid mains spikes on sensitive 12V equipment?

    From Guest at 7/5/11 1:46 AM
    This battery has only one port that's used for input and output of 12V power. Our High Capacity Rechargeable Lithium-Ion Battery has one input and one output, so it could be used while charging. We haven't tested how constant the current is when the adapter is being plugged in or unplugged.
  9. What is the max output current it can provide at 12 V ?

    From Guest at 7/19/11 2:39 AM
    The maximum current output is 2 Amps.
  10. How do I calculate how long this battery will power an LED fixture?

    From Guest at 8/1/11 2:52 PM
    To get the number of hours, simply divide the battery's Capacity (this one is 3800mA) by the light's power consumption in milli-amps (mA), which is listed in the product's Tech Specs tab. The 20 inch Brighter LED Light Bar, for example, uses 300 mA of electricity.
