Hi chaps, I have had a question - why only a single strip of nickel for parallel connections? It's a good question, the answer is because most of the current is between the series connections, of which I have 8 strips per series connection so more than enough. Each strip is rated for 35A, I'm running 90A battery between the two VESCs so each strip is passing current under 1/3rd of its actual rating.

Damn dude I had plans tonight and I missed them because I had to watch this video thanks a lot bro.🤙

[@sparticus_86hill43]

Loving this video Lee! I don't even know how to say WOW out loud so many times without people asking me what I'm watching. Don't worry I'm directing them to your better explanation! Keep up with the great work, this is ace!

[@LeeWright]

Thanks Mark! I've really enjoyed making I have really enjoyed making this series and I am glad you are enjoying watching it!

[@David-xr2sc]

The magnets are such a genius idea, never thought of that.

[@LeeWright]

Always with the magnets bro.... best way just be carefull 🤘

[@andrewfoskett2527]

Great video Lee. If only my better half would let me have a man cave like yours. 👍

[@LeeWright]

Thanks bro! You are welcome to come over whenever you like, have a couple of beers and mess around with skateboards 👊

[@simonchurchley8088]

Now that's what I call a battery Lee. Well done and wish I'd seen this before I started my battery as some good tips there. I especially liked using magnets for positioning and all the safety your using while making the battery. Easily the best video I have seen on making an esk8 battery so far and I watched loads before making mine.

[@LeeWright]

Thanks bro! I tried to stress safety as much as possible! Batteries can be dangerous! Glad you enjoyed the video bro!

[@scottharvey9764]

Nice job Lee that's a lot of spot welds. most 18650 packs ive seen on you tube have 4 spot welds maybe 6 per cell. That is 1 well put togeather pack you is the only 1 ive seen doing that connection with the main cable spreading the load

[@LeeWright]

Hi Mate, I have to credit my friend Mo with the idea - absolutely fantastic way to do it! I'm glad you enjoyed the video though bro!

[@tekoppentekoppen761]

Can't wait for part 2.

[@LeeWright]

tekoppen Thanks bro 🤙

[@hansselg1]

Thank you for all this information I'm thinking about building a new battery pack for my meepo v2 till I save enough to get a proper diy board I'm pretty sure I ruined it leaving my board in the car in the summer

[@LeeWright]

King Dong21 it’s possible the battery ran low and is now dead or the heat killed it. The best thing about building your own battery is you can move it to your DIY build so you only need to make it once.

[@TimWoodVlog]

Now I see why at the end of our group ride you had so much power left 😆

[@LeeWright]

Haha! Big battery!

[@Europium]

Nice video! Very informative!

[@LeeWright]

Thank you Billy!

[@Fungineers]

Nice video man! Learnt a lot from this series. Keep em coming.

[@LeeWright]

Hey man, glad you enjoyed it!

[@garrytoole]

Wow really interesting bro top work

[@peppapig2112]

Hi Lee, first class stuff, you are my new hero!Could you pls provide the link for the cheap spot welder you have used in the video? It seems to be working flawlessly

[@LeeWright]

Hey bro that welder failed on my spectacularly not long after. I'm now using the maletrics spot welder and its much better

[@MarkHybridZ]

Fair play lee! Once again another banger full of information! Top video homie!

[@LeeWright]

Mark HybridZ Thanks bruv!

[@esk8spirit362]

Someone that knows what he is doing. So hard to see. Very nice video., very nice pack.

[@LeeWright]

Thanks dude

[@shandoli]

10s8p? bloody hell mate. I need to move some furniture. Can I hire you? :)

[@LeeWright]

Haha, it's quite powerful but it's all about the range bro! I'm going to build another pack and see what the range is like!

[@GDoggProductions]

Great video Lee 💯 just what i was looking for XD !

[@LeeWright]

Nice one mate!

[@rauntsest7918]

I am planning to make battery pack out of makita 18v 6ah 2 series 3 parallel. It should be 36v 18000mah. I havent found any videos abot that kind of a battery build but i think it should be possible.

[@nickk1502]

Really getting into these videos man! Question, I have a few old 40v lithium ion tool batteries that I’ve taken apart. They are all Lithium ion and all 18650. Is there any danger in using a mix of these? All of them read around 3.75 volts when checked.

[@RBAERO]

Nice video. What point solder you use to solder the nickel?

[@JaydLawrence]

Which welder did you use? Have you moved to a better one since?

[@sleeper2173]

Could I ask Lee, have you had any fires etc while building lithium ion battery packs..thanks Victor

[@balazsmagashazy8474]

Hey, this series is awesome, I really love it. Could you help me where can I get a similar battery box as yours? Also I've seen you have a 3d printed template that helps gluing the batteries together, do you plan in the future to share the stl file?

[@LeeWright]

Hey man, thank you so much for the love! The case is a Underwater Kinetics Dry Box - I think it was the 309 one but check the internal dimensions to be sure. And yes of course I share all my designs with my subscribers! You can download it here my friend www.thingiverse.com/thing:3789160. Thank you for the sub!

[@mekotvrdo2881]

Hi Lee, your series is fantastic, I understood and learned a lot from this. I have a million questions running through my head. But here is the one that bothers me the most, on what should the whole system be built? if the battery is 10S8P = 37V / 160A whether the BMS should be 150A or there may be less current. Because if I use a flipsky vesc that has a current peak of 400A, will the BMS cut off the power and protect the battery. I am a beginner in diy, about how much the average current flow moves during normal use in your configuration.

[@LeeWright]

If the battery can only provide 160A then that's all it can provide, if you want a discharge BMS then pick one that can do just over your max discharge rate.

[@mekotvrdo2881]

@@LeeWright OK thanks, and will there be enough battery of these characteristics 10S/8P 30Q Samsung, for two engines 6374 max 80A and flipsky vesc 6.6 to push me 80 kg. And once again which BMS should I put on the battery? When I open the link from your BMS tell me that that BMS has 10S-15 and working currents. Is that ok?

[@mekotvrdo2881]

OK, I get it (at least I hope hahahah). I watched your video about BMS and I understood what it means to bypass and how to connect BMS. Thank you once again and I wish you much success in your future work. Good luck mate!

[@martynjones7699]

Lee, great video following this and you lasted vids closely as I m close to starting my first build. Can’t decide if I should go custom lip ion battery or just go lipoly. Can you let me know where you purchased you BMS. You link doesn’t have the option purchase. Thx for your dedication.

[@LeeWright]

Hey bro I think the best battery is the one that suits your needs. If you have the facilities I say go lithium ion

[@jogriffin7340]

@Lee Wright love the battery video, im making a second battery for my escooter. i can get 58 x samsung 18650 INR18650-15Q 1500mAh... will these be ok for my project? regards jo

[@carlosh9041]

Hi Lee, thank you for your great videos. I got one question. Is it possible to use a cautin to weld the batteries to the nickel? The thing is that I don't have a welder machine like yours. Thank you.

[@LeeWright]

Hey Carlos, I'm not sure what a cautin is bro?

[@rudypospisil4094]

What would you get if you went from 10s8p to 12s8p? How would your board benefit?

[@jeffreyh1025]

So, getting my battery plans nailed down, I think I am either going to go with a 10s8p like you, or a 12s7p. Since I’m using a 190kv motor with a 4.8:1 gear ration, my top speed is like 28mph with the 10s and 32ish mph with the 12s. Those are theoretical, but I think I am leaning towards the 12s7p, because it’s supposed to give ~24mph. Anyways, enough back story, have you had any issues with the 12AWG wires, and the current draw? I think the specs of our boards are fairly similar, and just wanted some reassurance on the wires. I bought some 12AWG using your link! Looking forward to the BMS I bought off your site!

[@LeeWright]

use the 10AWG and fo 12S bro! Actually, I think you bought the BMS off of us already - happy building!

[@jeffreyh1025]

Lee Wright haha true I did buy the 12s BMS from you, and going with a 10s would probably need a different BMS? I am going with the 12s7p, though!

[@kubburdigital]

Awesome stuff man, been thinking alot about battery setups, was going to make a bunch of 1s10p packs and then connect them in series with xt60's and a custom pcb, they are rated safe for 30 amps but can easily be used up to 100 amps, any thoughts on this ?

[@LeeWright]

If they can be used up to 100A you will be ok generally, your battery max is only ever seen briefly during normal conditions. if you do a lot of hills maybe find something else better.

[@dexshelton4483]

Where do you buy your cells?

[@AppleJuice069]

Is this a new version of the etoxx trampa geardrives or you fitted the mbs version on your trampa truck?

[@LeeWright]

Hi there. No it is the version of the cover that you can install external motor sensors in them, he has since sent me the other older style and I have those fitted now. I will do an update video soon

[@neilcanning1703]

Do you know anywhere in the UK I can buy a good battery pack? I got a cheap esk8, was about $400 and it takes '18650 10S3P 36V 7.5Ah 270Wh' according to the specs. I'm looking a spare, which from asking around facebook groups I've been told will be better than the one that came with it if I use good batteries. I was going to do it myself until I saw some videos. If I google it all I get is wish and aliexpress. I would really like to get my range up by having a spare in my bag.

[@LeeWright]

Shoot me a message on Instagram or an email from my description, we can build you a battery pack no probs!
