I am currently working on a small UPS for Router. My Router is a 9v version, not 12v are most Router.
I am going for a version with 2x 18650.
Initialy this was going to be my step up:
After some reflection, I came to why use both component at the same time??
I mean from my understand and from what I found around this BMS can charged already the 2x 18650 connected to it, of course when a 8-9v supply is applied to the BMS, so why use TP5100 which is kind of a charging Board. This board is used to charged 2x18650 in serie,if it is the objectif requested...
I means, my guess is to use only one component, it seems kind of pointless to use both of them.
Plus the TP5100 model, I got is only a charging board, it do not have Ouputs pins, so not able to proctect batts from over discharge! Initially, I went for this board mainly for the visual infomation of batteries status: the led (charging and charged) cause BMS got not info about charge status.
So the BMS alone is maybe the best choose.
Of course all this, is my personnal analysis, so maybe you can give some better recommandation.
Thx you in advance
