I recently received PL96e Paglink batteries for my Scarlet-X. The in-camera battery remaining percentage display doesn't work with the APU-IDX V-mount plate, but other than that, they do work as advertised. I also ordered a PL96t with a numerical LCD display but that one wasn't delivered yet. I think it's still being field tested.
They can be used and charged while linked. Hot swapping works and the time remaining display on the batteries themselves adjusts itself depending on the size of the battery stack. When you click on a button on the battery it displays the capacity of that battery with a 5 segment led. When you click the button a second time, it displays the time remaining for the entire stack.
I also got the PL16 two channel charger that charges 8 batteries in 9 hours. It has a built in 100W power supply with a 4-pin XLR connector. The charger has a fan, but it's not very loud. Maybe about the same as the Scarlet fan at 35-40%.
So far, I've been happy with this battery solution. I went for V-mount instead of AB because V-mount quite prevalent here in Europe.
