get it into your head that you should be silent and listen to be silent and listen to what they say to you Hello everyone, I promised I would do such a review on the battery from the TPL 4 hours Well, in principle, exactly the same as the 6 ac Yes in design So in the last review I said that I’m just sure that the banks in our four will be installed exactly the same as in the sixes And this is DMC c2p, there’s one person under this Here’s the review that’s already signing me up and I started to insult the answer is that such batteries do not exist, I even gave him a link from the official website to the Shit date, he shouts this is nonsense, the Shit date, here I have the Shit date, in short, well, you understand. Excellent, but that’s not the point, the point is the following, that is, we begin the review with disassembly, this is how the whole thing looks like, the board looks exactly like the board in the six, but friends, the elements we have already installed are these: the following date is sewn on these elements, I’ll tell you honestly, I searched the entire Internet, I couldn’t find it anywhere, I literally got one link where they are there were elements and She led to the site aba Well, I was already happy, I think somehow through Alibaba I’ll try to find this Dashi there, but having opened it by clicking on the link Of course, it told me that such a page does not exist from here I realized that apparently these batteries have been discontinued for a long time and absolutely nowhere on Aliexpress Well, I haven’t found them anywhere and on Valberes on the zone I haven’t looked anywhere I haven’t found these batteries. As they say, I wrote only Fun to the seller with a request Send me doshas for this one, for these jars, the seller answered me instantly, he answers I don’t know how to whom I immediately, and he wrote to me, I’m sorry, but we got rid of these batteries like So, let me send you other batteries Well, I don’t really have any options. You see, I’m honestly telling you, I of course agree, send them, I

’ve already sent them in principle, Although I don’t even know, friends, What kind of batteries that’s why now we ’ll look at this miracle battery, I won’t say anything about it for or against the battery, in principle, works normally, but let's measure our parallels Well, again, there is a temperature sensor, you see as thermal protection and thermal control, again, all the protections are as expected Well, and the indicator, these two side indicators, everything is like in the six, but I was tensed for one moment, that is, I disassembled this battery, or rather immediately charged it, then I disassembled it and began to measure And as soon as I began to use the probes Yeah, who will turn on the device, oh fool, so as soon as I became with probes on the power terminals. You see, now we have readings of 30 s to Well, let's count 31 million Yes, the normal readings of the 1959 battery when I charged it were 20 and 6 V. That's when I started and these readings just jumped me, that is, they jumped from beyond the scale to the minimum changed changed changed, I immediately thought that some kind of condenser was working or something like that But when I put my hand in my hand it gave me such a heat And what I discovered means let's take a decent parallel 826 406 tray pair 8 12 V and pay attention to the fourth parallel we have 394 V 7.8 mim Well, 8 mm and the fifth and last parallel we have 7.8 mm 413 V That is, everything is counting cells 4 to 413 there is one cell already told measured all the values ​​here I jumped I put my finger on the balancing remember in this board, I told you that there is balancing, that is, five key transistors and five resistors, the balancing here is passive, there is passive, there is active Well, who doesn’t know what passive passive balancing is, let’s say if we see one cell 3.94, the rest are four, roughly speaking, and 1 V, then the keys connect resistors to these four cells and these resistors, in the form of heat, remove the voltage from these batteries, thereby trying to equalize them here with this parallel, which is the smallest and they get very hot, as they say, and active balancing is that it is of course better, this is that from a more charged element, energy is transferred to a less charged one, that’s all, in principle, but passively, again as heat. Well, when I removed it from the balancing again, I put

my finger on the charger, it was impossible to hold it in my finger, so this balancing works, and perhaps that’s why when these resistors are connected, that’s all that happens to us, this whole circus with incomprehensible failures resistances Well, of course, again, I’m not sure, so I’m telling you my purely observations. You see, it costs clearly 30, roughly speaking, 1 MLM, which, in principle, somewhere corresponds to all these values. So , we have one bank that turns out to be in the region of 16 million. Well, if we probably take away the resistance, again , of all these nickel plates of the lamellas, then it will be in the region of 14-15 million, something like that, so that’s what I want to do now, we’ve already measured all this, we’ll probably measure it again now, literally I’ll put this battery on recharge for a couple of seconds and with the help of an E thermal imager I want to demonstrate to you how it will work actively. Yes, passive balancing will work actively, so we have everything here. Well, we’re trying to put it on

the charger, so it missed, then quickly remove it and show how the balancing works, the balancing seems to work exactly after charging is complete, during charging, in theory, it doesn’t work now, we’ll quickly remove the battery and the whole thing. I hope we’ll see Let the banks there recharge the aircraft a little I'll cut this thing out for a minute. Let it stand like that for a minute. Let's just quickly tear it off and look at our resistor elements and watch how they start to connect and heat up. You see two resistors already in action, so hot. Yes, it's already impossible to hold your finger like that. What is the temperature here? 69° 75°, depending on which point of the resistor to point at. Here's 6977, that is, they get so hot I can't, and so far it's working only two jars And it works, yes, only when charging and Let's now, while this whole thing is working, I'll try to demonstrate to you all these jumps in resistance, I'll hold it And you look Well, I hope that we can do it Opa We're off to see What is done and when you hold it in the scales and then to zero in the scales it counts and to zero now something doesn't go in the scales, here's a situation like some kind of condenser is still charging and discharging Opa saw it down to zero reset and then it will again Count Count and 0 That is, it’s off the scale Well, you have to keep it for a long time, in short, take my word for it You see what a pandemonium it turns out with resistance and yes, I want to now let’s measure the six again, it hasn’t been on the charger for a long time, we have 18 mi 17.5 mm 2077 V Yes, of course, it’s fully charged, well, let’s try it

for a little bit Let’s put it on charge and see if this battery will do the same pandemonium if there won't be such pandemonium then I at all Sorry, move over, I don't know why the same boards work differently on all these PVS batteries You see everything, but the charge is going on a little bit, what's going on with ours on our balancing Well, everything is still hot, two resistors, the rest are not working yet. But when I tested, that is, I charged for a long time and removed the charges, they probably worked All or only four But I checked with a thermal imager, so I think it's enough for checking Yes, where is this hook and Let's go with the platform, although we all remember that it's from a balanced can. It's excellent here and the battery is excellent, maybe the whole thing doesn't connect and works a little wrong, everything is dead, it's worth dead Therefore, friends, I don't know, but again, this battery works great, I didn't have any complaints on it, I did a little work. Of course, it had four cycles, charge discharge, four cycles worked, everything works fine, well now Let's with you Then we'll do a capacity test, let's see what kind there are 4 ampere hours here Yes, friends, and since I haven’t found a date for these elements Well, I think that the discharge current here will be somewhere around 0102 and since you probably won’t be able to buy such batteries anymore Yes, I think so in this store Although I don’t know who will buy such batteries, write reviews and comments Let’s fuck him since he’s a 4, we’ll give him 4 aper and let’s see how much he’ll give us Well, that is, today’s video of how such a test test pampering will be like this to say, to see what they are, I installed it and fully charged the battery, remove the chargers and Let's connect it to our loads, we have minus minus plus and plus So you won't fall off, buddy Well, I hope like this So on board the 1256 V battery, I set it to 4 a and decided that we will hammer it to the end, that is, 12 let's go, the process started, milliamps began to drip, that's what amperes we'll check it Well, for now I’ll put it on pause and then we’ll continue. And as I promised, let’s look

at the real current of this four-amp charging from the heater. Well, the people wanted to see how the battery was disconnected. Of course, I’m sure that I ’ll remove it earlier, but no matter what, I was distracted, I couldn’t control. So

we lost 352 hours, this is at 4 amperes. Well, accordingly, the test was carried out incorrectly. I’m saying this right away and I warned the time discharge 45 minutes 47 seconds These are the ones we have on the vehicle Let's disassemble the charger I'll take it apart and measure how much it will put into this battery Disassembled the charger is assembled and made quite well compared to the rest of the Chinese Well, let's hook up the battery first before hooking up the battery Let's measure what's left on it, otherwise I haven't measured it so what's left on it It's clear that it's a little a little bit under the accumulated energy So we have a constant change, so I hope you can see and look at 177.8 V Well, I mean that somewhere at 141 volts his rune is simple So, well, add it to charging somehow like this, we prepare the pliers the pliers we have at 600 and constant so a constant current and we put and we put it like this Makar And you probably can’t see a thing about Well , just like that, I’d like to figure out the wires, I’ll plug everything into a socket and the initial charge is 4.9 4.8 aper, that is, super, someone will say of course that my device is faulty again. Well, let them say that I’m confident in the device, I’ve probably shown it more than once and demonstrated it to you, please, almost 5 aper. This charger, that is, the charger is so super Well, again, it’s not clear how long it will last Well, what’s left is to put it all together No, don’t put it all together But what’s left is, let’s still run a minute on 40 amperes on my battery and see what voltage drop we have in a minute. I’m charging the battery, so people. Who

doubts the accuracy of the tester, there is a four-point bead on the power supply. Now I’ll show you the voltage, I set it to 21 V to 21 V, so People, I charged the battery, so let’s see on this forty ampere battery that it will show us this battery as a stand abacus found a timer all the work So, of course, let's connect the tester so where it will be more convenient Here, we'll probably have red here, plus green, hook it to minus, turn off the tester, so I hope you can see Yes, we have a parking lot, plus and minus So on board 206 V Well, let's go, the timer can also be seen so carefully I'm trying to connect I hope the bot is all right Yeah, it's not working Well, what are you going to do to connect it, I can't do it like this o So, let's go Yeah, let's go they didn’t drive 59 minutes, so it’s all about the wall. Here, I don’t know, you will see the focus is not where it goes, how sad everything in this life is. If I remove it like this and I’ll keep it like this. So, let’s go to 17.4 V, this is the voltage drop we have, that is, the battery doesn’t work very well. And right away the recovery started for us, you see. Well,

I think until 20 V, it will calmly recover, so that’s all for today with tests. So, our battery has warmed up in terms of heating, let me probably show you To what temperature does this device take a long time to start? Well, it feels like something like 30 degrees. Let's look. Yes, here we go 34 35° 34.9 35 let's take it there 36 30 how much is there 5.2 seems to be yes 34.6 34.7 37° here in this place Well, that is, a little bit 35.2 what we have on the lamellas 36.1 26.6 see black spots metal 35 on average 35 degrees Well, here’s the board all warm 34.7 degrees people that’s all on this probably this is a test not a test I don’t know what to call it

of course I would like to have ours for these bans suddenly unsubscribe for the sake of Well, for the sake of sport As they say, I’m interested in everything Thank you all until everything is gone the electricity runs out
