Since your mouse looks for one AA battery with voltage 1.5V and your LiPo has charged voltage 4.2V i don't recommend this. Even if it works for your mice it can immediately destroy different mouse. And there is no over-discharge protection. Why you didn't use the version of TP4056 with over-discharge protection and output pads?

As you see I stated in intro. This instructables just work with 2x (aa or aaa) battery mouse.
I am using this mouse for 3 years. I didnt encounter any problem. My TP4056 has feature that cut the power when lipo reach 4.2V. But yours one would be usable anyway.
Thanks for comment by the way :)
