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! Let's get started!

Not just the discharge, I personally like to go for a charge cycle range of roughly 4.1v to 3.3v I think the slight loss in capacity is generally worth it for longer cell life.
@Ricardo-sx7ez 3 жыл бұрын
@@vgamesx1 Can you link IC or components and the scheme (if possible) for 3.3v overdischarge protection please? I only found IC for 3.0v and it's a bit too low in my opinion as well.
@FlavoredCrayon 3 жыл бұрын
Yea 2.5 seems low but it also sounds like getting an ic that stops above 3 is difficult. Might be better to consider that feature as protection for the lipo exclusively and work a cutoff into the workflow/design of the product being powered. I would've loved to see a voltage indicator even if it was just a handful of leds to make it easier to stop manually. Not hard to add tho.
@sixtofive 3 жыл бұрын
2.5 v will be an issue for LiPo batteries, but Li-Ion would tolerate this much better without degrading the cells. With the size of the circuit board I could see wiring up a pair of 18650s in parallel for 6000 mah capacity working really well.
@vgamesx1 3 жыл бұрын
@@Ricardo-sx7ez Sorry, I'm not aware of any ICs that do that, there are some with a reference pin that can allow you to adjust the voltage but if I need that functionality I'll just use a microcontroller and there are a few ways of doing that, you use the onboard ADC, add an external ADC or use a voltage/current sensor. kzfaq.info/get/bejne/i6d6gK-F39ixaYU.html (you can skip the first 7 minutes) kzfaq.info/get/bejne/ma1ooNKS2szRgac.html It's a bit on the pricey side for battery monitoring but there's also the diyBMS project which I can highly recommend or just search for "how to measure voltage / monitor battery with [preferred micro of choice]"

I’ve done a lot of soldering but almost no surface mount soldering. I needed the capabilities of your design so I ordered a kit. I have a fine soldering iron and tips that work with the 1206 parts. I found that good lighting and some magnifying glasses were required and bought some thin solder and paste flux that worked with it. Yes the transition to 21st century hand soldering is possible! The work can be tedious so frequent breaks are quite helpful as was periodic cleanup of the solder residue with 91% alcohol. The circuit worked just fine when completed. I wanted a protected converter of 12-14V to 5V for a QRP-Labs Ultimate 3S WSPR transmitter and find this project served just fine. Thank you for making this available!

If the over discharge protection goes down to 2.5 v then using Li-Ion cells would probably be a better choice than LiPo. 18650 or 21700 would both work well. This is a great looking project kit! Congrats on getting it all together.

I was confused when I first saw this. The video straightened me out! I guess the bottom line is that this PCB needs to stay attached (more or less) to a single-cell LiPO battery to enable it to both power a 5V or 12V project, and then later recharge the battery. Looks good! Without this project, we're limited to powering things that only require ~3 V power (with a single-cell LiPO battery).

@jamesbra4410 Жыл бұрын
I like the USB type C breakout board idea but you could integrate that into the project. If you look on the breakout board then you see a resistor and a capacitor. The resistance for sinking any power is independent of the resistance that will be on the cable's end. So pull-down resistors will always be 5.1kOHM on the CC1 and CC2 pins of the USB type C on your board. Also it looks like there is a capacitor that probably goes to the Vbus line for filtering. In the case that you need a power supply without ripple you would need to filter the Vbus line, after combining all the pins labeled Vbus together, with a 10u capacitor or a Pi filter. As well you see that it comes with the standard communication pins Dp and Dn on the board, well you'd just route them together as a differential pair and wire them to some IC like a serial-to-UART CH340C specifically to have communication with an ESP.

Me too, I'd like to find a good design of 12VDC UPS based on two 18650 (for at least half an hour of backup power). This device should be able to stay permanently connected (so must be very safe) and delivering 8W to 10W of 12VDC regulated power. My intention is to provide uninterruptible power to a Fiber Optic router, originally powered by a AC/DC regulated 12VDC plugin module (this module should be reused to feed the mini UPS, so max 2S is required to preserve some margin for the LiPo charger. Might be necessary to use a Sepic converter for the regulated output if Vin >= Vout when AC powered).

I'm sure the guaranteed quality applies to the individual components e.g. from Texas instruments - and maybe the store can elaborate- but I'm guessing you can never exclude some manufacturing faults and there may not be an inherent guarantee if you assemble it yourself

Which one is the correct? Also, 2.5v is good for li-ion but isn’t it too low for lipo??? What’s the difference between overdischarge detection and overdischarge release? Is it that once it goes down to 2.5v it will disconnect the load and only until the cell voltage has gone up to 3v it will reconnect the batt?
