I am putting the finishing touches on a project that really needs to be battery powered. Everything was based to run directly from cell phone battery back power pack where the components and module power requirements are 3.3-4V. Two things have happened since that plan was developed. First, I can't find a pre-made enclosure that allows for easy removal (for charging) or replacement to put in the next battery pack. Second, I came across the TP4056 Li-Ion charger module and a few options for 3.7V Li-Ion battery packs (the 18650 single cell and a couple of 2 and 3 parallel cell options, 3.7V but higher mAHr).
I was thinking of this TP4056 module

With the separate battery and load outputs.
What are the thoughts on these units?
Can you charge multiple cells in parallel with one of these units? I have seen the posts on the problems with series charging, but not much confirmation on parallel charging.
