MH-CD42 Charge Discharge Module|USB 5V 2A Boost Converter Step-Up Power Module for Li-ion Batteries.

Hi guys ! You may remember that we talked about several modules that can be used to charge li- ion batteries in previous videos.Providing mobile power for your DIY projects has never been easier with the MH-CD42 Power DIY board! This tiny board offers simultaneous charge and discharge, lithium battery protection, and a 4 level LED indicator. Connect any kind of 3.7V Lithium battery to have a 5V output with current up to 2.1A.When charging, the four-level battery indicator starts with one flashing LED, meaning the battery is less than 25% full. After some time, 2 LED will lit up and the first one would stop flashing. That means your battery is 25% to 49% full. Your battery is fully charged when all 4 LEDs are lit and not flashing. In discharge mode, the same definition applies but in reverse.Today we will talk about the MH-cd42 li ion battery charge and discharge module.

Is there a way to didsable auto turn off function?

[@prizmacreations1821]

Nice job bro, well explained. Very useful... 🔥 🔥 🔥

[@ravindupererayt]

මේකනම් සිරාම module එකක්. Nice video බ්‍රෝ ♥🔥.

[@louiepascua1282]

if I the key trigger is continously grounded would this stay off/no output
even with appropriate load.

[@mustafabayzid]

Can I use this board as UPS for my 5V arduino or other project?

[@Robotronic12345]

Superb video ❤

[@theelectroroot4919]

Thank you very much 🤜🤛

[@JerryWu-ij2vf]

how about discharge cut-off voltage?
i wanna full dicharge 18650, thus i wish it can reach 2.7v (hope it wont distroy 18650

[@m.m.i.fernando8407]

Valuable video 👍🏻

[@theelectroroot4919]

thank you

ගොඩක් වටිනවා .පොඩි දෙයක් අහන්න ඕන. ඕකේ අවුට් එක mt3608 හෝ xl6009 වගේ බූස්ට් කන්වටර් භාවිතා කරන්න පුලුවන් ද රිචාර්ජබල් ලයිට් හදන්න ?

How to reduce the discharge current amps from 2.1 to 1 amp ?

[@theelectroroot4919]

why you need to change it. normaly Discharging current is changing acording to
load

[@christophervargasschebesta3752]

How i cand do if i want to keep working a ESP32 all day long in sleep function with this module, because you say above 50ma this module stop. It will be very usefull. my idea have its to more hours with the battery. If i conected i cand saved hours of workin. Exist a better way
