Tp4056 reverse voltage protection
#31
I wonder... Has anyone actually tested this solution in real life? I see too many people saying "Schottky Diode here" and "Schottky Diode there" but I have not seen a single person posting a real life example of implementing a charging station with TP4056's and Schottky Diodes

Hi all,

No way this thread can stop on the unanswered question "Has anyone actually tested this solution in real life?"... So I did the tests :-)

My conclusion ? Mosfets rule !

Detailed article and thrilling "will it blow ?" videos available on my blog here:

Kind regards,

Thanks for the testing done. Much appreciated. I had thought of using the mosfets, but I lack the know-how on how to go about building and testing circuits. I'm barely outta the womb in the electrical circuits area Tongue

And know we know! Great work! Big Grin

Yep I've had a few go pop when I haven't been paying attention to cell orientation. They just stop working and I put a bit of white foam in the slot till I replace it. lol

Good design of a protection circuit, how expensive are low resistance mosfets?

Google search for the IRL2203 Mosfet to be around $2.33 USD. If you go to digikey and look at their mosfet section and filter the results, you may be able to find a similar one with a cheaper price.

Errr... IRL2203 are about 2.5 EUR *for 10 pieces* on Aliexpress (free shipping), but there are cheaper suitable mosfets for sure. The 2203 is just what I had laying around.
If you're into SMD, FS8205A is at 0.60 EUR for 10 pieces, free shipping... That's a more realistic ratio to protect a 0.22 EUR device... :-)

Why can't I use IRFZ44N N channel MOSFET for the switching?.
It also has al ower resistance.
I tried but the module is not charging the battery even in the correct position.
