Hi Sebastien,
Thanks for bringing this to our attention! We’ve tested this battery module with that receiver, and didn’t see issues, so we’ll have to do some digging on this one! I can see conflicting info from the manufacturer:
A short-term fix would be to mount a resistor on the output of the module to trick it into being on all the time. This is a bit counterproductive as it will drain the battery though 
I’ve made a note to pull one of these out and see when it shuts off. We’ll update the product page accordingly.
