Suitable 4.5V - 5.5V LiPo batteries

I need to run a 5V fan from the same power supply as my LoPy4 board. The fan should run between 4.5V and 5.5V so I'm hoping to use this 4.8V LiPo battery:
Can anyone advise on if this should work with the LoPy4 and LiPo charging circuit?
I'd also be happy to hear alternative rechargeable batteries if you know of any.
@KiraKiraSoul That's not a LiPy battery, it is a NIHM battery pack. You can run the Lopy4 from it, but it will not be charged.
Better use a single 18650 LiPo cell (3000 mAh typcially) and use a step-up converter to get 5V for you fan (e.g. Pololu U1V11F5)
Edit: you may also find fans which run at 3.5 V and less. That may be easier.
