1. Powered by Standard 18650 Batteries


SlingIt is powered by 6 standard-sized, 5, 8 or 10 amp, rechargeable, lithium-ion, 18650 batteries.

Keep spare, charged batteries on-hand. When SlingIt batteries are drained, simply open SlingIt like a Flashlight, and load in 6 recharged batteries in about a minute.

Power on to generate 12 volts and up to 10 amps of power.


Many battery manufacturers consistently produce high-quality 18650 cells, including Panasonic, Samsung, LiIon Wholesale, and Tenergy. You find them all over the world in electric bikes, power tools, flashlights, and battery packs. To learn more scroll down.

18650 Battery and SlingIt Capacity


Standard size 18650, 5, 8 and 10 amp, rechargeable batteries typically advertise capacities between 2500 and 3500 milliamp hours (mAh). You load six of the same 18650 batteries into a SlingIt to generate 12 volts and up to 10 amps of power. When the system can’t deliver 12 volts via the power provided by the batteries, SlingIt shuts down the power to its 12 volt socket. When the power shuts down, swap out the drained batteries with charged batteries. Insert the drained batteries into smart chargers (of the same make and model) and the charger will tell you if any of the individual batteries are degraded. Replace any number of degraded batteries with good batteries. The degradation problems are resolved, not masked.


Why are we willing to let you quickly replace drained batteries with charged batteries rather then taking the pack off line to accommodate hours of (pack plug-in pack) recharging? Why do we enable you to detect and replace degraded batteries? Because, it’s not our job to sell batteries, whether or not those batteries are packed into packs. It’s not our job to sell you multiple packs, to overcome recharge times and degraded batteries.

We consider it our job to enable you to build a battery and smart charger inventory which to best ensure for you have safe access to power almost any where and any time.

During our SlingIt application tests:

  • Six 3500 mAh batteries energized a WOW 2160 lumen LED area light for over 3 hours.

  • Six 3500 mAh batteries recharges a mobile phone battery up to 7x (from 0% to 100%).

  • Six 3500 mAh batteries energizes a CleanIt water pump for over 3.5 hours.

Not bad for less than 12 ounces of battery weight.
