How to charge Crystalsky INTERNAL battery - anyone??

[flynsign]

I have the Crystalsky Ultra and I'm not sure if the piggy-back lipos are designed to charge the much smaller internal battery or if it has to be charged separately, anyone have an idea?

The internal battery is charged from the removable Crystalsky intelligent batteries. Please note the screen will not work when running on the internal backup battery only.
