Cheap power tools can be great so long as they are used as such. I work in furniture installation and cabinet making a bit. Run a full set of Makita brushless tools. They are amazing if you are going to be using and relying on them every day. But i also tell people if you are only going to be using a drill or something couple of times a year. Go and buy a cheap li ion based tool. No point spending $400 on a drill and impact kit then not using it for 6 months. Finding the battery has sat dead flat for months and is going to cost $100 for a replacement battery.
High Julian, those capacitors between primary and secondary are class Y capacitors, designed ho have very low leakage. They are there in order to suppress high frequency transients generated by the parasitic capacitance in the switching transformer. Since the switching converter operates at hundreds of kilohertz and the isolated output is completely floating even a small capacitance in the transformer can cause high frequency interferences on the output and mess with the device being powered. Those capacitors short the ac component of the output to the input drastically reducing EMI. This is so important that even ultra cheap SMPS have interference capacitors. I have seen cases where the absence of these capacitor caused the power supply to even interfere with itself, causing instability and voltage oscillations. Great video as always, keep it up!

Greetings all. It has been a bit since I have visited all my friends on Julian's site, the past weeks have been the closest I ever hope to get to hell. You see the damn covid crap kept my wonderful wife from having the test to see why her stomach was acting up so badly. Well last week they opened the surgery and she went in for the test, first requested in March. They found a very aggressive cancer had been eating at her stomach and has since moved into her liver and lungs. I am devastated, we have been married for over 50 year's. What I am asking is simple, please, if you believe in God, I don't care which religion you are, but please, a quick prayer for my wonderful wife that she can have the strength to fight this evil disease. I believe in prayer, if you do, please help me with this. Her name is Judy, God will know who you are talking about.
Looks nice, and good video! It you have the time, it might be worth doing a "big clive" and reverse engineering the charger, at least far enough to make a schematic of the power supply portion if not the whole thing. As an electronics beginner I'd definitely be interested in watching that to learn how they did it.
The batteries are also under the three year guarantee. I’ve exchanged one of the 20vTeam batteries in the past. Just keep the receipt out of the sun :-)
I assume they changed their policy. I had 2 batteries going to hell and when I called the company that deals with it they refused to replace the batteries because they were about 2 years old. The woman over the phone wasn’t friendly either. They just ensure a replacement within 6 months. Very annoying. At least a was able to reuse the remaining good cells.
@@ruinunes8251 Take them back to store and they’ll refund straight away in my experience. The batteries come into stock every three months or so with more tools, so I haven’t had issues getting a replacement.
@@AdamWelchUK well, I didn’t take them to the store. I just called the customer service which in turn gave me a number to call which I think they are the supplier? As I said, the women over the phone wasn’t friendly and sticking to the fact that the leaflet says clearly 6 months. Well, I don’t have the leaflet anymore... so I couldn’t confirm. Next time I’m going to Lidl I will speak to whoever is the manager.
I'm surprised a budget charger has two completely separate power supplies inside. I would have expected a single one with some circuit to switch between the two outputs. Also, if you're not in a hurry to get the batteries charged, a little tape over the extra contact will help keep the batteries and charger cooler.
When you got such a higher than expected power consumption with the second B1 battery, perhaps you should have tried that same battery in the other charging slot. It would have been interesting to see if the slots were balanced.
I must say in response to the Noddy's angle grinder comment that the 20v angle grinder they sell is a beast. Cutting 40mm unistrut is no problem for it etc. Still not fixed my two over discharged batteries (20v), the cells are fine but I can't reset the locked out controller to signal the charger. (That will teach me to use them on other tools...)
Hi Julian, I have a project that seems right up your alley. I have been attempting to work out how to charge power tool batteries safely with balancing via USB-C. I am living in a country that under normal circumstances it's difficult to receive parts from outside and with the current situation has made it nearly impossible. I have been taping the direct output of power tool batteries and using the 18v type to power things like fans, lights, internet routers and the TS-100 soldering iron without any fuss but the thing is the batteries always need to be charged by the mains. Only expensive brand specific DC to DC chargers are available. It would be so nice to cobble together an effective and safe solution enabling vehicle or solar charging without the use of inverters or expensive proprietary chargers. Direct charging with say a boost converter is simple enough but lacks balancing and is therefore bad for the life of the cells and potentially unsafe. You could use a balance charging pcb but they are usually designed for a specific pack configuration and may not work well for different capacity batteries. They also may lack a proprietary balancing algorithm for a specific brand? You can see my knowledge here is dropping off quickly. Third party aftermarket mains to DC chargers for nearly every brand of power tools exists so maybe this isn't the case, not sure? My first thought was to use a USB-C to DC USB decoy fast charge trigger like ruclips.net/video/cX4INWdC5UE/видео.html but that would only get voltage to the battery, again no balancing. But what if it were possible to put this inline with the DC side of a AC power tool charger? In my thinking a mains charger has all of the necessary components to make this work. The DC charging circuitry, the appropriate tabs to connect to the balancing of the cells and the shutoff of current when the battery is finished charging. Any thoughts? I am a big fan of your RUclips channel and I have learned a great amount over the years of watching, thank you so much. Cheerio, Mitch
How are both the charger and batteries holding up? I assume the charger may be covered by the 3 years warranty but I doubt about the batteries. I assume they changed their policy. I had recently 2 batteries going to hell and when I called the company that deals with it they refused to replace the batteries because they were about 2 years old. My batteries had minimal use. The woman over the phone wasn’t friendly either. They just ensure a replacement within 6 months. Very annoying. At least a was able to reuse the remaining good cells.
These tools are cheap, but made in germany to be sold there, so needs To meet tuv certification criteria. Good shit with cheeeeeap prices. For homegamers i know. Bought quite alot of tools from lidl, not yet disappointed
how much are they charging for the 4ah 20v packs? i was in lidl the other day and saw them but there was no price. ive already stripped a 4ah 12v pack for the cells but if those packs are cheap enough ill buy one for the cells :)
Very bad design if they have done that, imagine wobbly contact resistance.... Most things I have investigated use it with another pair of resistors to just get a voltage change the processor can see.
Interesting content as always Julian however you're just becoming a reviewer lately. More like big Clive. You seemed to have moved away from your tutorial stuff, missing them more. But like I said your content is always appreciated. Thank you you still get a thumbs up bud.
I bought a "Tacklife" drill from Amazon a while ago because it was cheap, has charger and battery, I must say, it's got plenty of torque, more than enough for my purposes and feels surprisingly robust. So yeah. I wasn't going to spend hundreds of pounds just to drill some holes in steel plate. Wish I had a pillar drill in a way but there we are. Maybe one day.
@BrocoliColonist to be fair I bought the drill back before this whole thing kicked off, but yeah, I hope British made becomes a thing again, even if it costs a little more. Mind you, I did just buy a Stihl strimmer but that's a German brand. expensive!

Thanks for testing a Made in Germany quality product, from Bochum, Ruhr area.
I was wondering where it was made...
Ah buts its not!
It's designed in Germany by Kopernass but made in china!
I was made there aswell and still live here
German grundlichkeit
Another cool video with different stuff 🤟

Thats how you build your input filtering properly. Nothing Else would not pass tuv testing.
My Piller drill is a bit so so but the rest of my parkside tools a good as gold.
My parkside piller drill is shit the motor overheats

Those batteries look very similar to the 12v TACKLIFE batteries which seem very hard to get now.

I have the 20v grinder too and it is spot on.
Hi, thanks for the excellent video. Will fast charging negatively affect the longevity of the batteries? Do they get hot? Greetings

The angle grinder is for none ferrios like aluminium so not really that good however, I do use to dehead nails and screws on a fence I have built.
What ever happened to enclosing you back patio for a new workspace, and that little diesel heater you had? How did it work?
Does anyone know if this charger has reverse polarity battery protection?
Julian could you review the extremely popular HX-3S-01 BMS please. I've used search and don't see you looking at it yet.
Cheap tools can be good just lower your expectations with the price 😂
These tools are cheap, but made in germany to be sold there, so needs To meet tuv certification criteria. Good shit with cheeeeeap prices. For homegamers i know. Bought quite alot of tools from lidl, not yet disappointed
Julian Love this very beautiful,
#RUclips I don't know what you have done but you need to let me access my watch later streams ASAP.
how much are they charging for the 4ah 20v packs? i was in lidl the other day and saw them but there was no price. ive already stripped a 4ah 12v pack for the cells but if those packs are cheap enough ill buy one for the cells :)
Re ID pin...
I'm guessing, but might it be programming charge current via a current mirror?
Very bad design if they have done that, imagine wobbly contact resistance.... Most things I have investigated use it with another pair of resistors to just get a voltage change the processor can see.
12:08 Did anyone get annoyed that the label is reversed on one of the batteries?

I like to call it as shitside . All the shitside products that i tried from lidl are garbage
Sorry mid-roll ad so stopped watching. Enjoy your videos but protesting RUclips's mid-rolls by not continuing to watch any videos they interrupt.
