[App_rpt-users] UPS for a PI 3 B+

[Mike]

While I can't comment on that board, I might suggest, if you are just 
looking for a more simple method to do a battery power that can be 
recharged while live...

Look on ebay for a few items...

18650 battery holder (3 or 4 cell)
https://www.ebay.com/itm/DIY-Black-Storage-Box-Holder-Case-For-1-2-4-x-18650-3-7V-Rechargeable-Batteries/112896485215?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D52935%26meid%3Dc04f481f1ee842f8963405c64a8b587e%26pid%3D100005%26rk%3D6%26rkt%3D12%26sd%3D202350734774%26itm%3D112896485215&_trksid=p2047675.c100005.m1851

This little critter which will both charge the cells and bosst the 
output from 3.7v to 5v

There are many ways of doing the same thing. This method of course does 
not integrate with software to warn you about battery condition or do 
automated shutdown but do you really need it ???

anyway, food for thought,
