USB C PD Wall Adapter

  • SL4-Ground Battery (2 batteries)
    • The batteries have a USB type C port onboard supplying up to 60 watts for powering devices such as a phone or laptop. 
    • These smart batteries have a screen for viewing a range of specs from voltage, and power output to lifetime charge cycles, and much more.* 
    • SL batteries utilize Lithium-Ion cells for more reliable performance and safer handling than LiPo battery cells. 
    • These batteries are not only for the Movi Pro and Movi Carbon! We have published CAD and made an API available for anyone to integrate this into their electronics. 
  • Movi Pro to SL Adapters (1 pair)
    • These adapters install onto the original Movi Pro battery plates without tools and feature a pair of 4pin Molex connectors for raw battery voltage for your accessories.**
  • SL Battery Charger 
    • The charger uses USB PD for both input for charging, and output to charge your laptop for additional functionality on the job.
    • Charging time for one pack is roughly one hour with a 100w USB C power brick***.

*The state of charge (SOC) indicator on the battery is always the most accurate, but there is a firmware update available for Movi Pro & Carbon (through the Movi Pro app), that allows you to select your battery type for increased accuracy of state of charge reporting on the back of the Movi. For more information about this, click here

**Please ensure that the devices you are powering from these ports can handle 6s voltage (18v-25.2v) or use a regulator to step down to the desired voltage. With the batteries directly powering these ports, you will lose power to any attached accessories during a battery hot-swap.
