    In this video I will have a look at the wemos d1 battery shield that "supposedly" can charge up a LiPo battery and boost its output voltage up to 5V. I will determine all the important features the board offers (like overdischarge or short circuit protection) and also test the efficiency of the boost converter.

    Thanks for the extensive testing. I was zoo lazy to do that. The missing protections are common for the tiny lipo protection circuits on the battery themselves. So there won't be a problem in the most cases. I rather keep the connector. It's a standard JST. You can crimp a counterpart to your battery and then it's easy to disconnect.. which will happen more often

    Notice that the chip itself is just a boost driver chip.. So, VOUT, is actually input pins (for sampling). For battery to VOUT(or SYS), there is not any protection.
    1. This chip itself has overcurrent protection, but it's for the chip. If you short the SYS, it just like you are shorting the battery...
    2. When the voltage is lower than setting (2.7v), it stops boost, and as the topology, it just connect battery to SYS directly. So their is no over-discharging protection.
    3. Other protections are just cut off Vin at some conditions.
    4. There is a circuit in datasheet comes with power path selection. This one you get is not suitable (but can, due to it have a diode connect from 5v in to Vsys) for charging and providing power at same time...

    • @FangfeiYang
      @FangfeiYang 7 років тому +1

      Yes.
      First, I've never used this chip. So I'm just analysing these things by some facts that I know...
      It can be just the problem of this kind of IC, the manufacturer is cheating about the values...
      But consider that 700ma to 990ma(min) is too ridiculous, I think the poor PCB design maybe the main reason.
      According to the datasheet, the charging part is a Linear regulator (it's not buck reuse the coil, it's a linear regulator...) which do not have a good efficiency and release heat. (We are talking about a 5V to 4.xxV LDO... with 1A)
      The chip will limit the current by measure the temperature. (in case it goes too high)
      In the datasheet they have warned that a bad heat design can result in lower charging current. So they recommend to use the copper on the bottom side as the heat sink by connect the back metal part on the chip to the bottom GND layer through vias.
      From the picture of the product on the ebay, I can hardly see any via on bottom layer that connect chip ground to the bottom layer... (I can see a hole at 7:24 but I'm not sure if it's a via...)
      Not mention they run the gnd wire under the coil...
      As a comparison, you can look at the reference PCB design from the manufacturer www.tpwics.com/nd.jsp?id=24&_np=2_403

    • @FangfeiYang

      I'm not talking about the wide of pcb trace...
      I can only find θja for this chip with no idea what the design is...
      But it would be affected by the design and diminish the current.. But I cannot say anymore about this unless I buy one of this board...
      Typical LDO like AMS1117 have a huge metal heatsink that almost as big as the battery chip itself... That's not the same story...

    • @FangfeiYang
      @FangfeiYang 7 років тому +1

      145℃ is max junction temperature (in limit mode it's 120℃) and in the figure of "complete charging cycle (2:45)", datasheet says θja = 130℃/W.
      But I don't think with well thermal condition, θja would be so large...
      So either the value is wrong or it means some other condition...

    Hey Great Scott, sorry I'm a bit late to comment to your video, but I've been trying to use 3.7V LI-PO battery to power my camera T3i which needs 7.4V to operate properly, after some digging I found out that I could use 2 boost converters to get to 7.4V required by the camera but I also learned that the capacity of the battery which is 5000mAh will drop significantly if I use such a combination (3.7v to 5V and then 5V to 7.4V), what do you think should I do, and do you think I can build a straight 3.7V to 7.4V charger and boost converter? thank you so much :)

  • @user-jp2pe3nn9f
    @user-jp2pe3nn9f 7 років тому +1

    Just a thought... Have you tried testing the maximum output current with the battery? The Input impedance of the source (battery vs bench power supply) makes great difference in the performance of the boost converter especially under load. I'd bet, the battery handles the current spikes from the boost converter better than the output filter of the bench power supply you are using (and don't forget the current protection kicking in from time to time). At least you could try placing a big (>1000uF) low esr capacitor at the battery terminals when testing with PSU and add a series inductance between the capacitor and the PSU. Otherwise, great video. Thanks!

    What do you recommend if you want stable 3.3V instead of 5V from the battery? Given that 3.3V is so similar to the battery's 4V and when discharged can get to 3.3V, would it be a smart idea to use just a buck converter or an LDO?

I measured the MT3608 board to take over one mA of quiescent current. Seeing this alternative board using so much less is a great feature,. Despite its shortcomings it may be quite useful in practice.

    GreatScott, the over discharge protection of the tp4056 kicks in at 2.5 volts. I have constantly read that 3 volts is the absolute minimum voltage that a lipo battery should be at before damage occurs. Is there something I am missing because every protection board I have come across has the same 2.5 volt cut off. Is this safe/a good idea? I do know that under a load a battery has a lower voltage and when the load is removed the battery gains back some voltage. I still wonder wether that cut off is too low.

    Hi there!! the R330 is a resistor or inductor? in schematics it looks like a RC filter for the input voltage pin.

    nice one, thank you! It would be awesome if you could make a video about transformerless power supply design, you know the one they make with capacitors ( sorry my field of study is computer science not electronics :D ) to convert 240v-120v AC to 5V DC.

      Kamran Aghlami no transformer means no isolation, if a fault occurs you could potentially have line voltage in your circuit and that's deadly

      @rogert151 you are right, see? I thought this would make a good topic to make a video upon since the name is very tempting for some one who does not know a lot and who is trying to make lightweight and small circuits where transformers are too bulky to consider.
      I'd like to see musts and mustn'ts of such power supplies, formulas to calculate power delivery and such.
      and of curse I can google all of that, but such video is a need in youtube since there is not much already and our fellow friend @GreatScott! is brilliant at explaining stuff.
      So it seemed like a good idea to me to ask for a video like that, so i did.

      @Jan Ciger Well I have failed to die by electrocution a couple of times already, enough to understand what I'm doing when I'm around main's lines, (or is it ever enough?) thanks for the notice though.
      I've heard some about how poor they perform, that's what I'm seeking. how Good/Bad of an idea it is to use them, dangers and hazards, why they exist then, formulas for power delivery and such.

    Is there something like this that can boost up to 12v output for LED strip or will you have to then connect this circuit to another step up converter to achieve 12v output?

    Good video!
    I'm wondering... Why not just use the circuit in a cheap, single cell battery pack like the ones from the dollar store. They charge the battery and boost to 5V on output, they have built-in protection(usually), and they come with a battery you can use elsewhere. Even the case can be useful!

      They are based on the TP5400 IC, so the behavior should be similar. Only difference though is that they use a 6.8uH inductor instead of the 4.7uH on GreatScott's board.

    Does this board do genuine load sharing? Meaning I could have this always plugged into USB and have it function as a mini-UPS when power goes out? I looked at a regular TP4056 and see that depending on the size of the load, it'll cause the battery to never detect end of charge and potentially cause issues. I'm looking to make some DIY emergency lights for power outages where it'll just be running a small constant current through an LED and if power goes out the battery will kick in to keep the LED going.

    You should check one of those Regulated e-cigarette mods. Evic VTC Mini for example would be a great thing to test, I'd love to see what type of circuit they use to regulate temperature of the atomizer resistance. They have this thing called Temperature Control, and Voltage control, and even bypass mode which theoretically acts as if the mod is outputting the Voltage of the battery .

    Hi I am really impressed about your skills, did you already try to charge small battery capacity ? Under 750mah ?
    I would like to see a video about this 🙂

    If I added over-voltage spike protection and a capacitor to the output of the boost converter, could I use this board as a short term uninterruptible power supply for a low current 5v device?

  • @Prashant5479
    @Prashant5479 10 місяців тому

    @GreatScott! Nice video Scott! This though did not work for me for the following reasons:
    1. output is not constant 5V, it is USB voltage - 0.2V.
    2. without USB voltage, it gave 3.7V or the battery voltage as the output, without any boost.
    So, I'll go back to the first solution that you showed - boost circuit + batt charging circuit.
    Maybe I'll look to combine them as you showed in one of your other videos.
    Thank you for making these amazing videos!
    Gave me confidence to make my own LiPo powered projects :) (y)

  • @professionalelectronics3158

    Was there a minimum current draw requirement from the load? Like how some boost circuits require the load to draw over 140mA in order to stay on?
