4 years later, still waiting for the update on how to make this board actually work to full capacity 😭
ikr
Yeah
Kid, I wish he was done
maybe he is not it's unknown
maybe he isn't it's unknown
It's called a OneWheel :P
Dont mix li-ions and lipos
Thanks for the comments everyone!! I appreciate the feedback! It turns out I really underestimated the current draw to the motors. I understood that the batteries I used didn't have high power output, but my hypothesis was that using two packs to share the load would be enough to compensate. _Wrong!_ It turns out I need at least 4 or 5!! Dangit!! I know better, I should've done the math on this first.
Geeky numbers section: So the motors are 2000W and the current draw is about 50 amps (at full speed). The battery system I added maxes out at about 20ish amps. The solution is to either use more packs in parallel, or make new packs with much higher power output ratings. So the issue had less to do with Voltage, and more to do with the battery's inability to provide enough energy fast enough.
Again, this is just yet _another_ hypothesis. I won't know if I'm right until I test it again. Another video solving this maybe?
Will Wren solve the mystery? Find out next time on Battery Busters.......
wrenthereaper no I'm to late wren please read my comment
Mr Moyaa Will he figure out the mystery? Or will he be wrendered helpless to the power of his car?
Star Blaze Very nice.... Very nice...
wrenthereaper another video I'd watch I love the DIY stuff. The Geeky science is good every once in awhile as long as it's fun for you in the process 👌🏻
Jake: "You're late"
Wren: "Here's a video with 7 million views"
Jake: "..."
......get rekt son
Now it’s 8mil
Yeah it's still 7M.
Jake: Ok boomer
8 mil
Why does every modified battery Wren makes look like a bomb.
McDuckee ikr!!!!
Because scientifically speaking bombs and batteries are the same things, they are a storage medium of lot of potential energy, just a battery is rigged to dish out the energy in a controlled manner, whereas a bomb is rigged to send it all out at once.
Ahsoka Tano so all im hearing is, they are just modified outputting bombs
Plot twist: it is
He is working for Corridor after all. :D
He needed a Battery Management System or "B.M.S." for short. There is one located on the Boosted Board, but it wont allow the onboard batteries to drop below 33volts. He needs a new B.M.S. to allow the Panasonic cells to match output voltage, to where both battery packs will run out at the same time. It will also make sure the cells are all equally charged to prevent a possible short or power surge.
👏👏👏👏👏👏

@@crookshankmc3955 it was a split second shot that was easy to miss. Sent me straight to the comment section though
Maybe have the extra battery’s just charge the existing battery
The problem is not the voltage, its the power output of the NCR18650B, even at 2 strings in parallel they can output maybe 12A which is not enough to power your boosted board at full power. I successfully ran my DIY EV VW bus using LiFeP04 and tesla 18650 cells for 3 years. I have the answer to your problem, you want to collab?
Yes! I just emailed you!
jehugarcia Sup man I would expect to see you here, live your videos.
I can't wait to see what happens! :D
Make this top comment so the board works better
It's also more accurate to measure the battery under load to determine how much you have left
Wren, you need to monitor the cell voltages under load. at rest the multimeter won't give true readings because current is basically 0 so the cell chemistry has time to build up charge.
Brian Dunphy you should also measure current draw under load as well
I agree and the fact that he doesn't have any sort of an integrated circuit for those batteries he added, worries me a lot, first of all he doesn't get to have them as energy efficient and second those things blow up sometimes so he needs to add some electronic wizardry down there.
18650 cells are stable as all hell actually, and if he got brand Panasonic ones there's a fair chance there's protection circuitry built into the cap.
The reason you get less power from them is deliberate, it limits the internal production of heat that causes failures.
The lipo batteries that fail are either:
-damaged in manufacturing
-cheap, high current cells with sloppy tolerances
-mistreated by eng. error or user negligence
Excellent point.
You're right, I DID need to check the voltages under load. I actually did mention that but it didn't make the cut. I didn't get my little cell checkers until after the trip and it's hard to use a multimeter while riding haha.
As for the circuitry/safety comments, no need to worry. These are the NCR18650B batteries which are super good. They're basically the best cells in this format you can get, and I got them directly from Panasonic. Also, wiring up these batteries with a BMS is overrated. That's not really needed these days for batteries, especially if they're bottom balanced.
This has legit been popping up in my recommendation for like 3 years and it still won’t go away
There's an option to stop the video being recommended. It's probably because you haven't watched the whole thing start to finish.

Wrong. Try using more amperage than they are rated for on a continuous draw. They will vent or even explode.

Nah I have my EpiWren just incase
epiwren omg hahahaha
Don't know if you already got a resolution to this, but here's the answer:
you need a DC to DC step up converter that will output 35 volts DC from whatever DC voltage the source is. However it would be somewhat difficult to find one that is rated at higher than 10 amps output, but you can fix that buy buying lets say 5 of those or even 10 of those and installing them in parallel output calibrated as the same output voltage - these DC to DC step up converters are generally very small, you would not need to worry about space consumption with them, however the larger of them can output a greater amount of amperage thus requiring much less of them (if you get one with the adjustable voltage output potentiometer) Assuming the motor of the skateboard requires no more than 50 Amps to operate as the highest prognosis, you can put 5 to 6 of these DC to DC step up converter to be covered for up to 60 amps of max current draw, that way, those batteries that you said can continue working down to 30 volts can continue to do so. the way this would work is: assuming your battery pack is down to lets say 33 volts, the controller would see a perfect 35 volts, as far as the controller of the device is concerned your battery is technically "full", but the minute voltage drops below 30 volts the whole thing would abruptly power off, you will feel the force of the power off as you will feel that acceleration just abruptly stopped and you will be on your own kinetic energy, but this is not really a problem, instead of gradually loosing power and speed you will just go from ON 100% full, to completely OFF at end end of the discharge of your battery pack.
You might want to put another set of two rows in parallel maybe more to the down section of the board if there is any space, you will multiply your power potential, acceleration and torque by a factor of 2 times. This is great specially since these batteries will output more energy at a time the more you parallel them. I guess for this is down to your available usable space and if you are willing to compromise the look of your board by potentially adding additions that would affect the overall physical size of the board (eg: adding another set of two rows of battery backs by the side of the board that WILL be seen with additions of wood board extensions to further extend available space to house more batteries. Hey I know it would look "ugly" but at least it would work much better and stronger).
m8ty.com why did i read all of this btw that is true but dc to dc was a little off but u fixed it which was really cool thanks
or get taller trucks under the board for more ground clearance and leave them under the board
Wrong!
I like their comics
Hmmm I'm no engineer but, what if you fabricated a board from scratch? You could design a new board and use a 3d printer to make it or even construct one using carbon fiber and have one set of the batteries stored internally and the other just as you had them? Too bad you did not have something like an alternator to keep them charged. Well good luck with your future builds.
Haha imagine you sing collenfurzes stuff for your outro haha
Honestly I'd love to see videos like this again. The day-by-day stuff
WREN FOR YOUR BATTERY PACK:
Below I have two possible solutions. However it should be noted that it is unhealthy for these two different types of batteries to be in parallel. Because of their different internal resistances, and therefore different voltages when depleted, the batteries undergo more strain, lowering their lifetime. I would suggest option 1 over option 2, but they could both improve performance.
Option 1:
Remove the boosted board battery pack from the series, and add a third and fourth battery pack in series with each other, but in parallel to your first two packs, to keep your voltage at 40. This way you have more amp hours overall, and all the battery packs have the same internal resistance and don't cause some of the power to be inaccessible.
Option 2: (if you don't want to buy the batteries for the new pack)
Simply add a switch to the boosted board batter pack, to be able to disconnect it. Once your boosted bored batter is low, then simply flick the switch, allowing the other batteries to release power.
I would not recommend a voltage step-up circuit, for a few reasons. Step-up circuits are not 100% efficient, so you would lose some power in the process. Also, while your voltage would increase, your current would of course decrease, and I assume current is also a bottleneck for the batteries you added.
Also if you want to see the charge of the batteries, getting a battery charging/control circuit is not expensive, and would both let you see the charge of the board, and allow you to more safely recharge your new battery packs.
If you have any questions, feel free to ask! (I'm studying computer science at a university right now, but many of my hobbies involve electronics.)
You'll want a double pole double throw switch rated for over 50 amps. (Assuming the motor is 2kW)
Lucas Or add a relay to the switch
Lucas . Only when u ride.
+Lucas He needs a switch that can handle a lot of current while the motors are on. True, it doesn´t have to switch around under load, but still.
YourAverageGamerPC I agree that option 1 is is the best bet. It would be the safest, as paired batteries of the same type/size/volt output are way less likely to have a critical failure.
And I don't pretend to be half as smart as some of you, but I am a battery tech for a local ecig company.
So I know a fair bit about 18650, 26650 batteries but mostly with I.M.R.(Lithium manganese oxide) and I.N.R.(Lithium manganese nickel). Lithium nickel cobalt aluminum oxide batteries have too low of a current for most mods so I haven't had the chance to work with them.
My question is, if he went with option two could he use 4 to 6 paired Imr Li-ion with a max current of 35 amps(efest makes them), to charge his boosted cell way faster then the a paired group of LiNiCoAlO2 could?
anybody else getting in recommened I thought this was new lmao

What you need to do is buy another charger off eBay and make an outlet with the battery packs to charge the board while you ride. Since it needs to be unplugged to ride, take out the sensor in the circuit board
I think this should be upvoted. This is the answer.
he needs another battery to charge the smaller battery
Boosted board's take a long time to charge
Our Daily Lives wouldn't work. These things can draw like 2000W at max, way more than any charger would handle.

Yeh
I thought the sameeeeee
Metoo! Kelsier is awesome
I made a little girl sound of excitement when I first saw it!! ☺💗
you need to add a flux capacitor and get it up to 21.6 jigawatts. this will work with plutonium. it also works by attaching a Mr Fusion to the motor. The Mr Fusion will run off just about anything including banana peels and pizza crust. There's other ways to get up to 21.6 jigawatts but they're much more difficult and require a lightning storm. best of luck.
EXCEEDINGLY imaginative!
Lol nice one!
AMAZING REFRENCE!!! LOVE IT
no you
Your about to see some serious shit
You are amazing, Wren!!! Even if it didn't quite work in the end, you had that crazy idea which you made possible, so still amazing!
5:12 excuse me im afraid of that diamond pickaxe
Overriding the boosted board original battery with another one of your packed batteries? That way it should check on the actual voltage of the "modded" battery and keep using the other two's. That's the first thing that came into my mind but I don't even know if it's possible!
Yeah, same thought here. Or even remove the old boosted battery and only go on the new ones. If thats possible...
I think the problem is that the boosted board has a voltage detection circuit that reduces the power to the board once the voltage gets below a specific point, even if he removed the original battery and then just used his 2 packs, they would still cut out at the same voltage as they do now, the battery packs he uses to add to the board would need to match the chemistry of the boards original battery, alternatively he would need a new motor controller board that can handle the new battery packs voltage range.
He took out the old cells, and put in his two batteries.
@1987therealfury: yep, this is exactly the case. DC/DC booster like other people comment is not viable due to the high currents. Mostlikely the booster controlboard has a few resistors to read in the battery voltage, you can modify them. Higher torque seems impossible to me as the motordriverboard is designed for the current which the boosterboard uses, higher current and thus torque is only possible with a more bulky motordriverboard (or 2 more motors and controllerboard on the other axel).
Dude, use the Capacitor Tank Circuit concept to draw all the energy from the Battery.
1:57 I like how that guy behind not giving a fuck on what's happening 😂
The passive aggression wren had was insane
use a voltage converter, the use up a little energy by themselves buzt maybe it will give you even more, with the current situation.
I Use one in a similar situation, but i dont know how good the work from small to big, mine change 52(down to ~30) to 24 Volts, mobile music amplifier, and it works quite well. Just be aware you need to at least cool it a little bit passively
EDIT:
yes, i didn´t think about the drop in voltage from the internal battery, hurr durr
intelligent me. Also didn´t think about deep-deloading (is this how it
works in english, not native, sorry, i mean the state of emptying the
battery so much it kills it).
Buuuut I have another idea: Get a new Driver fitting for the new battery packs, completely take out the internal battery, replace it (depending on its size) with one or more battery packs, cable that stuff up and you´re good to go. If there is no way to wire the driver in a fitting way to have feedback - which i can hardly imagine) set it up with a oneboardcomputer (again, is this right? smth like a raspberry pi, but that would be overkill), code a super simple app and send the batterystatus to your phone via bluetooth.
Or be fancy and put LEDs in the board, itself and make a onboard (see what i did there?) statuspanel. that might in fact be way easier, one chip may be enaugh to control that with the info from the driver :D
Boost converters are only about %90 efficient though
You could fry the board if you upcharge the batteries while they are full.
that is better than not utilising the remaining power. You could however get the "voltage booster" to activate when the voltage drops below a certain threshold. This would mean that you wouldn't lose any power unnecessarily. Shouldn't be too tricky!
Fuck the original battery and keep the new ones, maybe
heh "current situation"

I'm glad the Hover Junker money I paid went somewhere.
ISIS probably
It's freddiew(channel) money, he had it before hover Junkers, so your statement is invalid.
aaron4820 Capitalism for ya.
Source? Following HJ's development quite closely, he bought the Model S shortly after the alpha release of HJ. It could be a coincidence, but probably not.
Technically he got the Tesla before working on Hover Junkers. When Lionsgate and Freddie bought out his half of the Freddiew youtube channel he did pretty well for himself.
Tesla batteries aren't that big of a deal. They are just regular lithium-ion high-discharge batteries. Only major factor of a Tesla's power is that they use hundreds of those batteries. Using a Tesla battery to power any other everyday item isn't going to make your stuff turn into Optimus Prime.
but it makes a clickable video
nah what was a big deal was that no one had tried putting a fuck ton of those batteries in a car lol

Facts
Do you think you could use the custom battery packs to keep the board's original pack at full charge? Just an idea.
Frostburn that would be very inefficient and the batteries would still not be fully utilized.
That is smart. Instead of plugging the new pack directly on the existing one, he could plug the new pack in the charging port of the board in order to keep it charging while its running. Does the board works while it's plugged-in? That is the question.
It's still inefficient.
S-L-R it can be dangerous to charge and discharge at the same time also charging circuits are inefficient and can only charge the internal battery up to the voltage that they have unless you use a voltage step up
Yeah you would have to match the spec of the charging brick exactly. Also, do the math to check charge vs discharge rate.
when he said i need to borrow your car i thought he was gonna jump his skateboard
When he asked how to make the Tesla water pour faster:
Him: add another one!
Me: chop off the top of it.
the real question is ,is your battery pack in series or parallel , when they are series if one of your battery's dies it will cause you to lose use to the rest of your battery's power, and there is a power booster they are called transformers, but you don't want to use these since they will make your entire build inefficient for a small boost .
your best bet is to
- lower your motors power need by getting a new one
- add more battery's
-decrease the weight on the board to make it use less power
- try new barring on our board or clean out the old ones
- add a capacitor that you can plug in to the motors when your battery's are acting up
deathbunny omg you need to learn more
Transformers do not work for dc, they rely on the moving magnetic field of ac current to work. A dc to dc voltage changer is called a converter and works under different principles.
thanks for that @spider0804 I didn't know that transformers only work with ac .
Haha no, there are plenty of transformer designs that work very well with DC still using a typical transformer keeping efficiency very reasonable. Look up a flyback for example.
Friend the definition of a transformer is an energy transfer over a moving magnetic field and a non moving magnetic field....or stationary D.C.... does not transfer energy.

caught me by surprise seeing those names in a CD video hopefully they make a live action cosmere video at some point
Favorite part of this video
KISS: Remove the original battery and replace it with another pack of Panasonics!
Adding another pack would increase the range, but then there's still that 5V that he cannot use, he's trying to solve his problem which can be done with a voltage regulator, rather then throwing more power into the board.
It's just the Lifepo4 battery has a much lowest capacity, around the half of 1 Li-ion one, so he think the Lifepo4 stop at 3.35v but no, it's complety discharge when the li-ion are around 3.35v. He find 3.35v for the lifepo4 because he just takes the voltage on the cables of the original battery(the 2 big cables) but because he soldered the new Li-ions on them, the voltage of the 3 batteries are mixed and 3.35v is the average voltage, the lifepo4 is surly around 2,5v and the li-ion around 3,4.
He connected the batteries in parrallel so all the batteries should be the same.
Loved how he used some of colonfurzes outro for his
Crazy how far boards have come since this video...
I ride a WowGo 3 and get up to 12-14 miles on the standard battery they pair with the board.
The fact that even alternative budget boards can compete is a good sign
Mad props for Cosmere references. Bridge 4!
I need to get a Bridge 4 tattoo.
How you can use the battery packs power is make it so that you can charge the booster board battery while you are riding it
At first I thought he would have a rough time commuting with anything but a car in the States.
Then he mentioned a bike path and I was surprised.
Then that only available bike path was blocked and he had brave the streets, and everything was back to normal again.
i miss these types of videos by wren
You just doubled the value of that boosted board
Wewbi e trippled
quadrupled
Damn dude i could never understand parallel until i watched you pour out the water damn thanks
water and electricity are almost identical in the way they work.. from the example here, to series (pouring one bottle into another and pouring out on the end) to switches/faucets, hot/intake and ground/outlet, even how water/electricity is stored in the line until it has a way to continue.. voltage and amperage can be compared to PSI and pipe diameter.. it's good to use water analogies.
Parallel only increases the capacity not the output voltage it seems like he’s confusing that at times in the video. Putting the batteries in series will increase the voltage.
@@billjon2732 I noticed that too I was confused for a moment
This is some sort of underrated mark rober
The end roll of the snowball machine gun was mark rober lol
*9:28** me coming home after a long day of school.....*
Ask to EEVblog, he is an excellent electronic engineer. He is part of the UA-cam comunity.
+1 to this!
Jamer1Smith no one want to watch a 50 minute fucking video of a guy with a weird accent.
Jamer1Smith a lot of people want to
Remco Ardui no.. no one. except for nerds like you.
ok, you obviously didn't get the joke, but aren't we all a bit nerds about our biggest interests? Or aren't you interested in anything, in get case I would go to a psychiatrist because you might have a depression. Don't take this as hate, I'm just worried about you, I wouldn't want to loose such a valuatie youtuber like you, a Total gamer. Much love, your small penised friend.
"green light comes, batter charging"
*quick pause*
"Now it's blinking :0"
Why is there not a part two?? i just watched this today and really wanted to see if you got this to work
