Else, i should to use a relay for stop charge ?

Sorry for my bad langage 🙁 my english is very bad...

My present project includes both modules, the SIM800L and the TP4056.
Two questions please:
1. Can I use the TP4056 as an UPS? The 3.7v LiPo should provide power to an Arduino in case of main power loss.
If main power is normal it should charge the LiPo and also provide the Arduino with power.
2. I realized that the output of the TP4056 shows 3.5V while the LiPo itself shows 4.1V. Is this normal?
It's powered from a PC with USB.
Thanks in advance!
