Paul, I do have 1 question. Is there any compatibility issues with Profoto Compact/D1 Air systems?
Also, I understand the inverter takes a standard 12V sealed lead acid/AGM, is the Lithium cell compatible with the V2 inverter?
Can't answer with any authority about D1 . . . it depends on how well they designed their uP power supply. With a .9 second AC recycle time for 500WS it will drop the inverter voltage quite a but, so this could be a problem if they didn't consider this in the design of their uP power supply. If it's not well designed, it may crash.
Vagabond Mini can run from an SLA battery, but not nearly as efficiently as from its own Lithium. The inverter current is low enough to operate from most auto cigarette lighter sockets. Also, since the battery meter is designed for the 14.8V Lithium it will likely always show low or dead in indicating a 12V SLA battery.
As for V2 . . . it's inverter draws 60A from the battery and the Mini draws 20A, so Lithium battery is designed to produce 39A max.. So it can't be used with V2.
I could do a lithium pack for V2 but this would take complete redesign and higher capacity or different chemistry to get the 60A. There's a lot of cross engineering between the Mini inverter and it's Lithium battery. Lithiums must have well engineered "PCM" control circuitry built in to protect the cells from over charge, under charge and excess charge and discharge currents. So they are pretty much matched to the equipment they will operate.
