Dang you're crazy lol!! some maths needed there for the weight adjustment on the shock and rider limit i reckon to account for that oversized battery packs lol. awesome vid and thanks for sharing!
Congrats! Guess thats the biggest S18 battery mod now! My S18 has „only“ 1850wh....i made new battery packs myself and added them under handle and as brakepads. Nice job!
Amazing I was thinking of doing something similar but either creating an external battery basket to set in the front and the rear and and batteries based an the distance I was trying to travel or have a backpack version with a long chord that I can plug in for long eides
So I'm planning to do a battery upgrade myself and my plan is to get 20 (genuine tesla model 3 4800mah 21700 cells) and then try to add 1 cell to each of the 20 (3 cell) packs ( I believe the S18 has a 20s3p 21700 battery array, correct?) So this would create a 20s4p array adding 4800mah to the existing 13Ah that the 3p setup currently provides (1100wh ÷ 84v = 13Ah) so effectively I should end up with close to 1500wh plus a 4p setup which will increase the Amp output and reduce the risk of cutout and add 15-20 km range ... According to my math at least. So my question is: how difficult is it going to be to isolate each of the (20) 3cell 21700 packs so that an additional 21700 can be added in parallel? I'm hoping that this type of mod will not increase the overall size of the machine and possibly the additional cells will be able to be concealed in some custom "powerpads" (hehe.. no pun intended)
I’m about to add the two extra half packs I have to my S18. I’m wondering if I might have any noticeable change in the way it rides if I were to secure them to the front sides considering the front already has more battery weight. I’m sure it’ll ride ok if each side is in balance but just curious whether it’d be better to try to secure them towards the back sides to make the wheel more balanced front to back. What do you think?
Kevin, I have a question, did you just solder the new wire to the X90 connector or you desoldered the wired X90 first and then re-soldered the wires and the connector?
Best to cut it off and joint the bold wires and solder it to a new x90 plug. Because if you desolder and reuse the plug it take a lot longer and sometimes the plug can be damage by the heat.
can you provide a teardown picture of the battery inside? I'm going to build an active balance circuit but don't know if I could put it in. 8x8x3mm or so for the dimension..
yes in my case i got the spare set of the shell cover and all the side and bacl panels. Just incase if it doesn't work out, i can put it all back to the way it was.
If you have not touch the system board and only change the tire. please check the motor cable and the control cable and the connector plug to make sure there is no damage it.
Hi, mate! Do you know what are the thinner wires in battery backs for? Aren't they serve for battery balance infromation for the controller? I suppose it's not a good idea to just put them parallel.... Please, correct me if I'm mistaking...
Correct, sort of. They serve the function that balance leads would normally fill, giving you access to the individual cells. IF they are put in parallel and kept balanced well by the charge controller, there shouldn't be any issues. By putting the cells in parallel, your just increasing the capacity of the cells. DON'T PUT THEM IN SERIES!!!! YOUR EUC MAY EXPLODE. Series increases voltage by stacking the cells electronically, the controller board probably won't be able to handle that, where-as it shouldn't have that issue with parallel.
Hello Kevin Kevin!! is there anything one needs to do to upgrade the motherboard when installing more battery packs (or software)??? and When are you going do to do the range test??? :D
Dammn... its beefed up now.. how does it stand now that is wider between your legs?... is it comfortable? This must be the fattest wheel now out there.
It looks like S18 on steroid. With the width at 25cm it not too bad just a little wider than the EXN. Just have to get use to it and get my leg condition to it.The weight is lighter than the EX at 33.7kg.
Best to charge it to the same level before connecting them together or when you connect all the battery together the battery will level off. If the old one is fully charged and the new one is not it will take a while for the battery to level off.
If you got time stock charger is good. But if you want to charge quick use 5a charger. But 5a fast charger will only charge up to 98% if you want 100% use stock charger to finish off.
@@eucupgrades what i mean't to say was after installing these extra packs do u charge all these packs with stock charger in one go or do u charge them one by one with separate charger for each pack??? i assume all these aftermarket packs have different ah but same voltage right??
@@matelslug1 have you see the video part 1? Once the battery are install, it's inside the unit so you don't take battery out to charge separately you just charge as normal in one goes otherwise it's much work.
Why would you think that?? Each pack has its own BMS and all packs are in parallel anyways! Weird how so many EUC people have no idea about the electronics inside their wheels. So common to see stupid comments like this…
That’s such a great idea for better range without buying new wheels. I love my KS18. I will update too. Thanks for sharing.
This is awesome. Great job been waiting for someone to do this.
Glad you liked it!
Great job Kevin.
Battery upgrade is looking nice !!!
Dang you're crazy lol!! some maths needed there for the weight adjustment on the shock and rider limit i reckon to account for that oversized battery packs lol. awesome vid and thanks for sharing!
with the extra battery the shock has been pumb up to 220psi to take my weight of 76kg.
@@eucupgrades just a little bit of extra air then lol
@@oddtechman with the batteries he added its like 5-7 kg (10-12lbs) extra

Nice. How many miles do you get on your?
@@eucupgrades i am very heavy...using 22wh per one km. That’s about 80-85km...
you got pics?
Up ;) I'am also interested in your setup!
Amazing I was thinking of doing something similar but either creating an external battery basket to set in the front and the rear and and batteries based an the distance I was trying to travel or have a backpack version with a long chord that I can plug in for long eides
I would love to see a ks22 double up in battery since the batteries are more uniform and will probably be a better stack job 😉 let's do it

Nice work 👊
The coating on the board looks like what is called conformal coating.
Awesome!
Always wondered what I should do with my spare packs :o
yes in my case i got the spare set of the shell cover and all the side and bacl panels. Just incase if it doesn't work out, i can put it all back to the way it was.
Grate work! Do you think it works to make the whole battery pack external, like in a backpack and have it on the back, I have an MSP.
incredible
Did you have to 3D print any parts to make it waterproof again? And where do I find those plans at. I am going to do this upgrade this winter.
Please help. My S18 won’t turn off. I changed the tire and now when I turn off wheel, the brake tail light keeps blinking.
If you have not touch the system board and only change the tire. please check the motor cable and the control cable and the connector plug to make sure there is no damage it.
Good luck on your upgrade. Wander how will it be with 2 new front batteries sticking up so much.
you can watch part 2 / 3 & range test on my other video to fine out.

The weather have not been good in UK. Been rainnng for a week already and still going.
@@eucupgrades I am ready to purchase the accessories. I have emailed you 😊
Sorry wrong channel I replied to
I have subscribed, , but where is Part 2 ?😂
Wonder how the finished wheel looks like..
How was the ride of the modded s18 a year later? Did any problems arised due to the battery mod? Thanks
My Mega S18 is still my best long distance suspension wheel. No problem whatsoever.
@@eucupgrades thats amazing! thanks for sharing this!
quick question, what are the larger pedal additions you have on your pedals?
They are 6mm aluminium plates using self tapping screw through from the bottom up just long enough to act as spike padals.
@@eucupgrades Thank you!
i wish we see step by step
Can you upgrade the battery for the Abraham's
Funny you said that. I was going to do it. But i think it be too heavy with 4050wh.

nice done
Where can I buy those batteries 🔋??? Please
you can email them.

so do u charge all these batteries with stock s18 charger or separately???

Will vibrate to pieces...
Battery management system will be out of sink mosvets can melt
definetly needs an active fan on those mosfets
Why would you think that?? Each pack has its own BMS and all packs are in parallel anyways! Weird how so many EUC people have no idea about the electronics inside their wheels. So common to see stupid comments like this…
