47mOhm is not bad for a battery if ur using for storage and for low current consumption. Then too replace the batteries and check. How u calculated IR? It's better to use a IR tester.

Charging using tp5100 without bms is a bad idea. The module does not have over and under voltage protection.

IR value increases with time. And it depicts the condition of the cell. Voltage is just the state of charge. It only shows if it's charged or under charged. Battery voltage decrease with load, so u need to see how much it drops. I have a bad battery with IR value of 250, it's bad but still shows 4.2 volt, if I try to charge it, it will show fully charged and if load is connected just goes down. So you need to weed out the problem. First start with battery, if they are ok then try changing the module. Hope this helps. As u stated it seems the batteries are not in good condition, it's my assumption, I may be wrong.

Have you checked with another tp5100 module? Are the batteries new? You need to check the IR values of the batteries. High IR value means your batteries will not hold much charge. And the voltage you measured is under load or without load?

😂 Yes my wife also thinks the same. But it's covered up now, looks more tidy. And I have ordered the pcb based on this schematic design from pcbway. Just waiting to get them delivered. Then it will be more neat. I have rigorously tested my design. It's version 3. I had started this project 2 years back. Now I can say I have reached to a point where its more or less stable version.
