DIY LiPo Supercharger! (Charge, Protect, 5V/12V Boost V2)

Rating: 4.5; Vote: 2
In this video I will present you my DIY LiPo Supercharger circuit, co-produced with Elektor! If you connect a LiPo battery to it, then the circuit can charge it up with 1A of current through a USB Type-C port, it protects the battery from overcharge, over-discharge and a short circuit and it can even boost the battery voltage up to 5V or 12V with an output current of 1. 5A and 0. 75A respectively. This circuit is basically an improved version of my old Charge/Protect/5V Boost circuit. But this time you can even buy it as a kit!

1) Using some liquid flux for soldering may help for getting better results.
2) For the short circuit protection, limiting the current may be dangerous. I think that part should be updated in the upcoming versions!
All in all, great job and congratulations!

Maybe somebody from the comments or even Scott can help me, I want to build an Powerbank with an 3 Cell LiPo battery (I also want to switch them) but the huge problem is, that I don't knew which parts I should pick.
pls help

As a very uneducated tinkerer, would there be an easy way for me to swap out components to get more amps from the 12v supply?
Not sure if that would require a complete different choice, or just a few component swaps.

Really cool! It just so happened that I made a QC2. 0 PCB very recently for a powerbank which used a TPS61088 and such an e-Fuse. That chip was QFN-20 and I just wish it was so easy to solder as this one (for SMD standards ofc.

Nice video and I am glad your design advanced into production.
I searched Elektor's site and didn't find the Gerber or schematics (all I saw were some specs.
Efuse? I am not familiar with this component

The first revision was my very first assembled smd board and I used it for my college project and It sure wasn't easy to build but worked great! Thanks!
I'll probably use this one for my next project!

Great video and awesome board! I recommend that you clean that flux with some iso. It'll help the people you influence to clean their boards as well which is just a great thing to practice.

This is great news. Really excited about your projects in kit form. I'd love to see them all, but I guess you should start with the most popular. Thanks for all your really excellent work

Awesome project! Love it. Request for future project, convert an ordinary clothing iron to an SMD hot plate. Lcd/led display to shows target temperature and real world temperature.

Fantastic. Love the constant improvement. Oh, and you should check out AMTECH 559 flux, will make your solder joints perfect esp with low melt solder.
