Lovely build man!
very nice workmanship and you took a nice shot People understand everything in detail.thanks😇
Excellent work 👍👍👍 . Thanks for sharing
The build was too satisfying 😃love it😘😘
Nice build. But everything comes in ready to assemble, it's looks quite easy to build. I like the enclosure.
Brilliant upgrade
Your video editing make it fun to watch 👍
Great job, thank you brother. You are so talented
Thank you so much!
Great job.
I like that you included that the "pro" guy liked the gas better.... Which does not take anything away from your project.... That actually looked like a bigger gas motor and cutting blade.... He probably likes it because it's faster.... But who knows.....
That could be an interesting project.... Get a bigger gas one, and electrify it....
I got a Makita electric leaf blower a few months ago....... For what I do, I really like it. Blow out my garage, blow out my front sidewalk entry-way area... Works really good, and I don't have to mess around with gas & oil like my gas one.... I have the batteries, because I have a bunch of Makita tools.... I like it.
Thank you, I'm so glad that you like my work.
This would work in my "Battery Backpack" idea.😀
Excellent work ❤️
Love from India ❤️🔥
If you've got the right tools it looks a great build it yourself kit
Yes, thank you!
Nice work 👍 looked like a fun project.
Yes, I like this kink of project.
This reminds me of the old Black & Decker Thundervolt system.
My hero, you are such an inspiration, greetings from The Mediterranean
Thank you so much! I'm so glad about your greetings.
good job. This video is some sort of Li-Ion ASMR.
Yes, I'm glad you like it.
The bms connections already has metal pads soldered on it so you can spot weld the nickel tabs directly on the board, otherwise, nice build! 😊
Recently, I have had to refurbish a battery pack and the BMS had the same pads and it was a pain to remove the welded nickel from them, so I have de-soldered these small pads from the PCB and soldered the new nickel strips directly. In the future when the batteries will die, I can still re-solder the BMS easily.
@@bonafide9085 same here. I just desolder it rather than ripping the tabs. For new ones, if I don't plan to weld onto the bms pads, I desolder them and keep them for another project, and then solder the nickel tabs to the pcb.
@@quandiy5164 Thank you so much for the tips.
@@bonafide9085 Yes, I'm thinking about this too :)
Great suggestion i like it
Nice beat during battery attached in holder
very nice i will search for a 21700 kit, i liked the idea!
“Try the battery.”
Dan DeQuille, “The Big Bonanza.”
I hope to build my own battery in the future, so I can try it myself!
You are a really genius 🤠 sir 👏👏
Nice video, keep it up, thanks for sharing :)
Nice battery kit
Great work
I really need one off those
Great work with great skills ❤
nice build
i wish I had that battery pack 😩😩
Great video!
LG hg2 cells. Awesome power.
Already liked cuz I know it's going to be good👌
Thank you!
This would be a nice power bank
Good job bro
Love it! This was a very practical build that lets you go all day without swapping batteries all the time.
Also, your custom stickers look very clean and professional.
Thank you very much!
give daigrame and discrib then all the best
watching from the Philippines ❤️
Very good 🤝
Good job boy 👍
Tolle Idee
My man taking it straight to mud.
Great job, thanks for sharing with us, but you were supposed to complete the meat by spot welding because the electronic board was provided with nickel plates that you put the welding on
very very clean job ! love seeing this, where did you find this special bms in order to do it this way?
My Neighbour is also a ''weed eater''
Or smoker
Very good!
Very nice job
Thank you! Cheers!
Good video very well
Универсальное решение на каждый день, на данный широкий спектр инструмента, лайк👍
Круто!!! Спасибо за видео!!!
Thank you!
Amazing brother amazing nice video
Cool project. Though when soldering the ground and positive terminals for the BMS, don't use the fan, as the cooling of the tin, soldering iron, and BMS board makes the soldered connection weaker than normal. You want to get the tin looking nice and smooth.
This, I felt like every single solder connection looked cold.
What is the point of that seal if there are openings for dirt and moisture to get around the handle?
You should add straps, back padding and a solar charger to the rig.
Yes, thank you!
Portable electrically driven trimmer is quite convenient thing.
Yes, it is.
What a clean work, amazing like always. You probably have a great knowledge about electronic too. One suggestion though, The BMS terminals have small metal sheet on them, the propose of them is that you can also spot weld the battery nickles to the BMS rather than soldering it(Maybe you are aware of it and and prefer soldering, anyway i just wanted to mention it:))
Yes, you are right. I think soldering is more reliable. Anyway thank you!
@@gear_show can you please share the link where can we get the box, bms, Nikel stripe, etc.. the entire kit to make DIY
@@kmuralikrishna1582 wtf he has like 20k machineries even I can do more clean work then him if I have those machineries
No es un ventilador es un extractor, para no contaminantes de la soldadura
@@g4gamerby427 It's Illutsion. You just think you can do it, but in reality you can not. 20K machinery??? Nope his machineries are in total under 1000 usd. Maybe he has more expensive devices, but the devices he is using in these videos are not that special. It's all about himself and his art, not his tools.

Nice build. You should get into designing and 3D printing your own DC tools. Fusion 360 is free for hobbyists. SLA printers can print accurately to 22 micron now (Phrozen 8K Mini) and the Elegoo ABS resin is very rough. I designed and printed a larger head for my DC string trimmer and it holds up well to the punishment.
Okay, I do appreciate with your sharing.
@@gear_show how can I order one
@@kirkaustin8469 B&Q and waiting for a reply are us sells them 🤣
@@officialmysteriousrider130 how can I get one from you
Super bro
you know you suppose to weld the tabs on the pcb too, thats why theres a metal square tab already soldered on there lol
Yes, thank you for the tips. I think soldering is more reliable.
Très bien merci beaucoup
Awesome!
very cool x
This battery suitable for small area size or home used but its great!
Thank you!
This the best video have ever seen
Thank you!
Very good
Thanks
Hi thank you for sharing your skills if that is possible show us how to repair servo motors
You're welcome! I will try my best.
Get a goat 🐐 LOL , great build 👌🏻
Very good I very liked thank sir God bless you ❤
So nice of you
Great job I got an old bose soundock series 3 it works with 18v cd (no problem) but also sais -18v can you make it work with batteries? It could be a great video
Really long life battery 😉
You can spot-weld also on the board
okay, thank you!
Thats nice! Can you make a video to double a ebike battery with an extra battery?
What tool do you use for stick a plate on battery ?
You need bigger tip on that soldering iron for better heat transfer and easier soldering.
Thanks for the tip!
Parabéns pelo vídeo, muito legal mesmo, qual é a autonomia tá bateria trabalhando direto?
Um abraço aqui do Brasil 🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷
Muito Obrigado!
Please share list of tools to make battery pack and availability.
Why solder you can use your spot welder for the balancing tabs the main +- maybe you need to solder it because of high current will passtru it
How long can this weed eater run on a full charge?
I suggest a 5A fuse, drawing more than 5A will cause fire on your pack because all your pack + and - stands only to a single nickel plate strip, consider adding more nickel strips (stacked) on your +/- ends.
Great idea, thank you for sharing!
Can you post the link were can we buy the box with the BMS. thanks a lot
Nice build but why don't you share the links of material which you used(especially BMS)?
Cara, coloca isso pra venda prfv, quero muito comprar um pronto assim já
Hat das BMS beb Akku schutz für unterspannung ?
Could you share link to BMS you use? Where did you buy it?
Congratulations good job,I try to do the same whit no results, what's the secret to match the battery whit all electric tools?
Please , how to change nailer gun cord to cordlesss
Really the BMS is impressive here, where to order only BMS
This is 48x18 right? Can you suggest a buying link for 48x30 Lifepo4
10:17 sht that's not mowing, that's grass removal :D
5:19 Your soldering iron doesn’t store enough heat to melt the blobs into a single pool. You can consider something stronger like gun type irons with large transformers in them. 15 seconds from cold to hot, it would be a single pool.
And needs a little more flux
at 18000mayh, I think it's time you use Ah instead, then it's 18 and it makes a lot more cents. That's why we don't say I spent 1,000,000,000 cents on a used car. Small numbers are easier. It's kind of like building a spot welder that needs a separate button instead of using a momentary in the welding head so you don't have to synchronise your hand holding the spot welder with the button in your other hand. That wouldn't be very efficient!
Powerful and Silent. Fantastic. ;0)) Grüßle
Yes, it is.
Can you provide a link for the batteries? Where can I buy them from?
where did you buy the battery?
Can an escooter's controller use 14s6p 52v 20ah battery when original battery is 48v 20ah 13s6p battery? Or must series and parallels be same or something?
hi i like the video, where can buy all the materials needed?thank you
На плате уже припаяны площадки к которым можно было точечной сваркой приварить))) К ним не надо паяться было. А если паяться, то их лучше было бы удалить.
Конечно, точечной лучше и безопасно.
nice
Bro where did you get the 48 volt BMS board
Good
1:40 - just like Bishop in Aliens. ☺
Hello my friend, very nice work. I want to ask you how I can get this battery
which BMS do you used??
