Yea hopefully I can keep up with the posting before my health fails again. Thanks for your support

Pretty sure the leads are straight copper. Ive noticed that any leads I use like this will stick after awhile. I probably just need a light sanding. But so far I used this Tab welder on 4 battery pack. 2 x 3s, 1 x 3s2p, 5s3p and 7s3p. Seems to do an ok job, just wished the battery lasted longer and the leads didn't get to hot.

The most important question when putting it in the same room as your spouse as I will :).

I'm sorry I don't understand?

I'll have to see if I can find what I used. I remember it was a 5000mah and boost of 175c. Your going to find that most of these types use mofsets. Even the spendy kweld and maletrex welders. Typically 3s and 4s. Now I use those flat cells spim08hp 3s2p. That gives me a boost of 600 amps to around 1200. Most of the welders like this just needs a minimum of 200 amps.

​@@njfulwider5 Thank very much

It's been awhile, but I don't remember there being any issues. If I remember correctly, the only issue I had was the bottom nuts on the bottom of the power case would sometimes get stuck and spin, but still came out after. But I don't believe I had the issues you mentioned. It was a long time since I did this video. Pretty sure once I taped it up so no small pieces went in the componits and short it out. I just drilled the holes starring with a tiny bit and working my way up slowly till I had the right size. No issues. I've also seen it done without holes, they just layed the plugs down and soldered on. I'd use Google and you'd be surprised how many different ways there are to do it. I also did a 24v version, but I need to edit part 2 of the video

I've heard of this with the lower power ones, but I'm unsure what problem they had. I've purchased 6 of these(750-1200w) and 4 used in projects, but I haven't had and issues with them. These are probably the cheapest bang for your buck, when it comes to power supply. Think another Diyer said these are running around 20-40$. Wish I had more information on these, sorry.

@@njfulwider5 thank you very much for your experience, yes it is a 750w, it must push an Amd RX 580 video card at full capacity I have verified it should absorb a maximum of 350w, this power supply model as soon as I start a game this electrical noise starts, I try to attach a uploaded video on google drive to let you understand the noise it makes. drive.google.com/file/d/1M-B59olAQisHTEYkVlfvKz4-Wf15Z-FJ/view?usp=drivesdk

with 850w power supply, only the noise of the fans is heard drive.google.com/file/d/1E_enri886EnyU-HHrplgRxD0DMJR_VQJ/view?usp=drivesdk

@Lorenzo Vene sound like it could be the fan or a defective relay. That's not A sound you'd here from the curcuit board. Almost sounds like the relay is kicking on and off super fast. Or the fan speeding up because of a temperature change.

@@njfulwider5 thanks for your availability and your experience in the field, no I assure you it's not the fan, indeed it is very silent, until I activate a load, for example the rx580 video card at low speed normal operations example video and navigation does nothing, as soon as you start a game that noise starts and lasts for the entire game time, it stops as soon as you exit the gaming session, the video card I have seen the characteristics at full capacity does not exceed 200w, being a 750W it should not in the least affect this small load .

Good thing this ain't my day jpb👍👍👍👍👍

If I remember correctly, I tried this also on a psu and shorted something. I couldn't get it over 12.8V. But there is a video, the guy did some mod to the electrical board with the potentiometers and got it up that high. But I'm not sure what the video name is. Sorry, wish I could of been more useful.

Your 100% correct. I usually use an ohm law calculator. The power supply is only 1200watt. At 90v, I might get 10-13 amps. But personally if I needed 90v, I would never go above 5amp. Typically to be safe, I never use more than 50% power and sometimes 75% power with good cooling. I've built multiple power supplies and Posted the videos. To date, I haven't had any issues using this formula. This power supply was built mainly for a 13s ebike and any battery over what my reaktor 300watt 30amp charge could do. I have another power supply that's capable of 50v 20amps, I'll be building soon. Would love to see your builds👍👍👍👍👍👍👍

@@njfulwider5 well after I sold the bike bike they kind of got mothballed. But I certainly recommend building a portable charger like I have. Most BMS systems will allow you to trickle charge whilst you ride. I used to do fast food delivery. I had my portable 40ah battery with step up/ charger coupled to the top of my frame and it would charge for about 3 and half hours non stop usually I would set it to 4 amps ish whilst I rode to deliveries. Obviously that wouldn't keep up with the useage of the bike but I was delivering then coming back for 5 to 10 minutes waiting for the next then going out again. So it kept up. I did add a fan and used it at 15 amps and it kept up quite well. Even the 40ah of battery got warm though as the input end was pushing out quite a lump current lol. Had to massively beef up the wires. If you've got old batteries laying around defo so it as a project and post a video. People will love the idea I think as you can use any voltage battery lower than your bikes to charge it. Quite handy.

I'd have to look, it's been a long time since I created it. If I come across it, I'll shoot you a message 👍👍👍👍👍👍👍

No issues after 3 years. One of my favorite Chinese spot welders👍👍👍👍👍

Forgot to mention, most of these Chinese welders are open faced with no protection. This one actually has a face. The big solder traces are to help carry the amperage. I used both solder and twisted solid copper wire for this.

Hit me up when you have the video done, just encase I miss it. Are you talking about adding a battery instead? I've made a few of those, with my favorite being my lunch box tab welder. I've even made them out of supercaps. I've got 2 of those new mini spot welders coming in this week. That dual pulse color screen welder and a 6 gear welder I found on Amazon used or damaged box for 20$. On this welder, I plan on swapping the screen with the dual pulse version. Both versions are interested changeable. It's one of the reasons I cut a big square. At the time I could only find them in China. Now there everywhere. That has a nice screen and it should make this even more powerful.

Forgot I have a Malectrics welder and it's awesome. I also have a kweld with kcaps and case. But the kweld I haven't put together yet. I'm going to wait till I build my newest bench powersupply 1000w. Kweld is supposed to be king of welders. But we shall see.

Yea it was a slip of the tongue. In the video, I mentioned the vendor says 400,000-1,000,000. But there was no way it had a voltage like that. Someone else a few years back caught my slip of the tongue. As for you asking if I was born like that??? That I can not answer, it would be like asking you the same question. Thanks for posting👍👍👍👍👍👍

I really like the pelican cases. I use them for everything, but I'm always looking for something better!👍👍👍👍

I added a active balancer charging board capable of 1 amp per series, not sure if you missed that part. Combined with the bms, that also has balance. It keeps everything balanced pretty good. There are active balancer capable of 5 amps now. I might purchase one and try it out. Thanks for watching 👍👍👍👍👍

@@njfulwider5 thanks for the reply but I still don't understand how it would isolate one parallel group considered they are wired in series .

@@dust6242 It's not a single cell battery. I'm assuming when you say parallel group, this is what you mean. This battery has 14 series voltage, with each series having 10 batteries in parallel. 14series10parallel. Each series is 4.2v, plus the next series. So 4.2 x 14 series=58.8volts total. Each parallel is 10 batteries with a. Average of 3400mah. So total mah is 34,000 or 34 amp hour. So this 14s10p is 58.8volts and 34 amp hour. Hope that made sense 👍👍👍

@@njfulwider5 thank you again my friend I understand exactly how the battery is configured but I don't is how a bms can balance it individual cells while they are all connected as one. Thanks for your time

@@dust6242 the active balancer waits for the voltage to unbalance.. then slowly using resistors and other componits, balance the battery. Unfortunately, there is no charge, just regulation. It does this per cell. The bms is a little different. It only balances when the battery is being charged. This is per cell. Typically around 1/2 amp. Using resistor, the bms regulates the voltage to match a low cell. The cheap bmses are kinda crap when it balances. Reason you get better performance from the more pricey ones, like a Daily BMS. Other than that the bms cuts voltages if charged to high, or discharged to low. It only takes one cell for this. Have you ever watch JehuGarcia's channel. That guy knows a ton about batteries. I learned almost everything from his channel. Let me know and I'll shoot over a link for you. He can probably explain way way better than me.
