Hi,
I'm currently fiddling with a project where I trying to put some sort of a controller, BMS, charger together. In these my first attempts, I'm using the well known circuits before attempting more serious stuff.. The circuits I'm working with now, is the TP4056. The well known little Li-Ion charger, which comes in 2 editions. The one I have seen the most, is the one without the extra protection function. Actually I'm not quite sure how this works, so I've been avoiding these. Because, everywhere I've read about these, you are just told that the charger comes with a built-in protection!?!? Protection of over discharging? Because it can't be protection against overcharging, because TP4056 is exactly a charger which has been a success because it works well, and charges to 4.1V.
1. So please, please set me straight here. What does it do? Does it protect against discharging if you use the connections marked "B+" and "B-" ??
And if it's under-voltage it's protecting against, then what about circuits where several e.g. 18650's is put in parallel with a TP4056 each?? How would this be able to work. I've seen several attempts to do just that, and this is what I'm going to do too. Not quite, but similar basics...
And
2. If I want to use a single 18650 battery with the TP4056 without the extra protection, is it then OK if I connect the " 1S BMS " . One of the little mini BMS PCB's??
Hoping for some kind'ish words here
