I am a rookie in this game, but I have been searching for quality, comprehensive videos on how to assemble a Li-ion battery pack with 18650 cells for my adult trike, and I have found them. Thanks - you ROCK!!!

[@Sillyazzmofo1]

That battery pack was a work of art. Nice job

[@mrspark2438]

Though it is adequate for fuse wire and cell connections, I would avoid using solder as only means of connection between busbars and look into bolting them together. Solder is highly discouraged in the NEC due to its unreliable nature, tendency to break. Love the channel, keep it up. - MrSpark (Electrician)

[@dustinmeier9753]

I noticed something in this video. You have a type ABC fire extinguisher. That will only make a lithium fire angry. You need a type D (more expensive, but suited for lithium fires). Love the informative videos, keep them coming!

[@killerbeenl83]

I would have put the power bars each on a side. Too prevent short in case of accident. Or prevent handling issues.

[@mcghanconcrete]

Awesome . I had a 1965 21 window when I was a kid . I modified a 1 1/2 inch anti sway bar off of a 1976 Chevy suburban by shortening the arms so the geometry matched the lower control arms . I used the lower shock mounts to connect the sway bar with 1/4 inch flat bar . I used 1/2 inch U bolts to mount the sway bar to the lower tube on the front axle beam . Of course the bus was lowered and I had 60 series Goodyear NCT tires at the time It handled like a slot car . Very little body roll . I notice you had quite a bit when you were on the track . It will help keep the bus from rolling .It will HUGE difference

[@rcprojectable]

Keep up the great work, Jehu! Your pack is coming along great!

[@PRAGEETHKARUNADHEERA]

Hey @jehu, to reduce stress on batteries close to busbars, best is to put them at opposite ends. Then all batteries will basically see same inductive and resistive loads. Keep great stuff coming! Cheers from Australia!

[@HBPowerwall]

This video started my quest to compile 1120 cells for my own pack ...

[@cuddles6938]

Jehu, I have a dog leash which clips around the seat bar between top and bottom cushions. It's about 2 feet long or so and gives my dog plenty of leash to lay down on the back seat safely. Noticed your setup thought maybe you might want to check the big box pet store for something better.

[@mondotv4216]

You're running that off one 3.6V pack? What kind of motor is it? I'll have to go back and check out your build vid. And you haven't balanced the cells when charging? Probably OK short term, but long term the pack is sure to go out of balance. I would imagine for that many cells in parallel you'll need a custom BMS.

[@Research0digo]

Hi Armando, What is a custom BMS, please? Thank you.

[@Moon___man]

those curtis controllers are beasts... we use them at work for indoor electric karts.. those things are amazing

[@Craysv2]

I don't see any balance leads on your batteries. how do you balance every individual cell, compared to every other cell. So you don't overcharge 1 and under charge the other ? Also is it smart to glue the copper bar right against the sides of batteries ?

[@martianmartian5840]

Yes. Over charge one battery and it will burst into flames...!!!! So yes can some one explain how its done professionally and safely ?

[@johnmay5957]

You don't need balancing for his design.. he us running every cell together.. for a total voltage of 4.2v. they balance themselves. now if he had multiple cells in series for higher voltage packs i would agree with you.. but with his design the entire pack changes voltage together, one cannot be higher than the others or it would discharge into the others. the drawback is that if one cell fails, it will bring down the entire pack.. but that is why he fused the cells, if one cell shorted out and tried to draw too much current the fuse would simply blow and the pack would live on. my question is how is he boosting the low 4.2v to something high enough to run a electric motor.

[@BLUEBIRD-1960]

And don’t forget to put your seatbelt on too. You do great work and I want to see you keep doing it.

[@andreyd7898]

As far as I know in the electric the TESLA uses Panasonic batteries NCR18650PF 2,9 Ah, since they can be max discharge 10A. 85000W / 400V = 212.5 A, 212.5 A / 2.9 A = 73.27 ~ 74 pieces 400V / 4.2 = 95.2 ~ 96 * 74 pcs pc = 7104 units, about such quantity in Tesla talked

[@furulevi]

don't heat up the copper bar (at 4:34), heat only the solder, use a quality soldering paste instead and the solder will attach in half a second to the copper

[@McDaniel77]

What is the possible distance, the weight of the car, is there a energy regain downhill? Nice Video! Maybe with Solar-Panels as a roof, the car could recharge a little bit during daylight.

[@jontanguy989]

Brother, test out the 'tesla switch' battery configuration. You'll need three of your battery cell configurations to run it. Hook two units together in series, and then hook up the negatives of both the single and series units. The negative will now be the positive of the single unit, and the positive will be the positive from the series units. If you can find an ingenious way of swapping the battery unit's positions, (the single battery unit will actually charge as you drive) then perhaps you can drive for a much longer time, or even forever. I think that a lithium capacitor would work far better in this case though as there will most likely be a lot of amperage going through.

[@ILasaroff]

How do you balance the cells during charging? The sense wires 6:52 from your charger are not connected to anything. I would personally go for sport welding for that many cells, bars and fuses.

[@suharinos]

Just 2 things to remember: Do NOT solder batteries. Do NOT use solder for any joints passing through high current.

[@jehugarcia]

+suha rinos I just soldered a buss bar that will see 700A

[@suharinos]

Sure you did, sure you can. It just shows how little you know how things should be done the right way. Ask Tesla and get surprised.

[@jehugarcia]

+suha rinos if things were done "the right way". I wouldn't be in America, wouldn't have started my business or be driving my diy electric car. So no, I don't care what others think is the right way but instead challenge it everyday.

[@OpenGL4ever]

suha rinos is right, you should listen to him or at least understand what he says. Starting a business is easy, but there is a difference between doing quality work and dabbling.

[@fahadaliqaiser9663]

[@erikvandamme6915]

Looks great, what about balanced chargeing,? Spot welding nickel strips instead of soldering copper?

[@onegreenev]

That battery pack is nice and clean. I see your not having issues with mixing chemistries.

[@jehugarcia]

yeah so far I'm only used Sanyo 18650FM and Panasonic CGR18650E, I don't know exacly what chemistry they are, they might be the same?

[@onegreenev]

jehugarcia I was meaning mixing your Sanyo pack with your LIFePO4 pack. The Sanyo are not LiFePO4 chemistry and a higher voltage. At least you have not mentioned any issues with different voltages being mixed. Or do you just charge your Sanyo Pack to match your other TS cells?

[@jehugarcia]

Oh I see, yeah I make sure to charge lifePo to 3.5v and the LiCoO2 cells to 4.2v before the test, I ran the test then disconnected before recharging, I'm going to do a discharge capacity test on the 2nd module tonight

[@diywithpapo4576]

[@tomvarley4344]

Great video, would like to see a thermal image of the wiring and battery interconnects to see the losses, soldering the flexibles to the bus bar looks like a potential (no pun intended) area for loss

[@wvXvxvXvw]

I stopped using solder on battery bars for high current packs. It can easily break and melt. Now I build pre-wired battery cases that allow me to simply drop the cells in, put the lid on and bolt the flanges down to guarantee a solid connection without the possibility of a solder or battery bar failure. All it takes to do this is a piece of sheet rock(you can use plywood but there is a chance of fire), spade bit that is the same size as your cells, battery bars and springs(for constant tension, not 100% required if your case is perfect).

[@donkeywaffle]

Would be a good job for a 3d printer! could design the entire box in pieces, print them out, epoxy it together.

[@micglobal]

[@Cocothemechanic]

im planning on building an electric motorcycle. Im thinking about making the pack 72v 60a. My question is can I have 20 cells in parallel to achieve the 60 amps and the rest in series to achieve the 72 volts? Or should i build small modules to reach my desired voltage and amperage?

[@jehugarcia]

yeah if you get the 3100mah panasonic 18650 cells you will have 3.1 x 20 = 62AH to reach 72v you'll need 19 or 20 cells. So your pack needs 20p20s = 400 cells

[@GavinFreedomLover]

I built a 58.6 v battery pack which works well on my 1kw bike, it has 120 cells from scrap laptop batteries, if you are going to buy new you might as well just buy an energica for 13 grand, otherwise have a look at the projct where the guy uses 1200 18650's for a jeep

You may not be able to afford an attorney but you still can represent yourself, so make sure you do. I don't recall you saying his name in any way, shape, or form, so he is just once again trying to bully you so don't let him. There is no way he could win because the only thing you said was "someone said" and since you did not name him specifically, he does not have a chance to win; unless you don't show... Oh, now that I've read your comment again, you did say on your last episode so I am referring to this video. If you've said his name directly in another video so what. I'm no lawyer but I do know this is America and we are still FREE to say what ever we want. If I were you, if he does bring a case against you I would counter sue him to show how he has threatened you and how he is costing your business venture and let the cards fall where they may. It might cost you filing fees, but I don't know for sure. Filing fees are not much compared to the slim attorney that will cost him. I say this because I grow tired of bullies as I have dealt with more than my share along the years. Even if you said Joe Blow is my biggest critic and he says this or that, Joe Blow has NO CASE because your words have done him NO WRONG. Your words have not caused him to seek a therapist or anything like that so what's his beef other then to be an ASS? Stand up for your rights.

[@lisagichard7625]

Just a question regarding fusing on the negative side. I have notice that other tubers making these modules are fusing the negative also. I agree with positive side only but I am curious as to why some consider this necessary? Can you expand on this at all? Fusing a ground connection seems to be reason enough to me not to do this? Great videos and you are a nature in front of the camera.

[@zarknorggreenscale6661]

That is a lot of work to be adding a fuse to each of those batteries and to wire them all up in Parallel. Now you can see the main batteries for the bus under the rear with the motor. Just wondering what are you using this pack for? Is it used to power the controller or other electronics on the bus or being used to supplement the main battery packs? 4v at 900 Amps just doesn't seam like it be enough to get it going, but maybe for cruising speed.

[@Haibinsun]

Every cell need to be monitored, otherwise if one cell damaged, it would pull the whole package down. And probably you need a thermometer, Tesla uses water cooling system for their batteries.

[@suharinos]

electric motor needs only one gear.

[@nikolatesla2977]

nice work! very clean even seeing the cut scene of the motor and frame, all out great precision work!

[@swedensy]

Update. Do not do anything you see here or you put your life and others at risk. --------------------------always use use cell balancing PCB with over current and low voltage protection.

If using a typical single 300 watts 60 cell solar panel, How many of these 18650 can the solar panel charge in full sunshine?

[@fullboostturbo1]

Bout 18,650 of these 18650 cells should charge up fully in just 18,650 Nano seconds in Full Sunshine, but only if you use a mere 4.2 volts from your 12/24 volt Solar Cell.

[@David-yg8tf]

FAKE. ..but inspirational video. The 3.7V pack didn't power the van. But is part of a hidden power bank under the VAN total over $15K. 1:21.

[@jehugarcia]

+David "The 3.7V pack didn't power the van" I connected in series to the existing pack so it did power the samba.

[@David-yg8tf]

Your video has a genuine intention. .. While obvious to your followers, it took me a while to figure that out because I'm not verse in this field.

[@angelcortes9051]

It seems that it triggered you to learn something new.

[@grndragon2443]

when building a battery pack from reclaimed cells, do you check for the internal resistance of each cell?

[@jehugarcia]

+grn dragon no, it's irrelevant when pairing so many of them

[@grndragon2443]

I ask because maybe I'm doing something wrong. I tried charging 4 18650's in series a couple times with less then 0.2 volts difference. on my imax clone I normally 2 cells at 3.85 and 2 at 4.5 when done. And that's at 0.5amps total.

[@wompstopm123]

wow dude, your playing the vsauce music

[@shadowhacker27]

Vsauce does music now?

[@TRX450RVlogger]

It's not Vsauce's Music. It's just a Random Music of Choice they both happened to pick.

[@wompstopm123]

TRX VLOGGER its actually composed by jake chudnow specificaly for the vsauce videos. you may be thinking of kevin macleod of something

[@edwardhewitt6578]

brother you are doing amazing work, I like the whole Electric thing and the sounds neat too,I had a bus like yours with a 1200cc gas back in the day, in fact I left home in it .

[@CalvinCai_Frisbee]

vsauce music, and why cant you use a higher voltage? its more efficient

[@MCMinerHQ]

vsauce in no way own it though!

[@CalvinCai_Frisbee]

MCMinerHQ i know, it just reminds me of vsauce

[@jehugarcia]

Vsauce is great! Higher voltage is indeed better, but on the affordable HPEVS systems are capped at 130V and 174V on their curtis controllers

[@BixbyConsequence]

Will you be returning to this project? These vehicles are always a joy to see restored. Thanks for your videos.

[@TonnyCassidy]

that car running on 3.7vdc .........awesome

[@Alteriukas]

Actually it's about 400VDC total

[@furkanyigit1669]

parallel connection, how?

[@Berecz]

If I understand, you have it wired parallel so the whole pack gives the nominal voltage of 3,7V. Is it then converted to the voltage the motor needs with a DC/DC converter?

[@jackass315]

dog collars tied to the roof , you really need to not do that , get them a box or a cage that is secured to the vehicle for transporting them , it seems cruel but its nowhere near as cruel as snapping their necks in an accident or emergency stop

[@slaughterround643]

he has a better system now, he's said

[@rizkyp]

I don't get it. The motor only run on 1s150p of lithium ion how is that possible with only 3.7v nominal? What motor are you using? I only a see single pack of 150 18650 cells in 1s150p config.

[@jehugarcia]

+Rizki Praam 30x 1s150p wired in series so 30s150p

[@atenrok]

bullshit. That needs to be spot-welded and the video would be 1min long.

[@MLFranklin]

You always make the coolest projects, dude.

[@elaeroplano]

Question: Is there no ballancing required?

[@EraZz187]

it is...

[@elaeroplano]

I have a special question to you. I want to use one 18650 cell to get more capacity for longer runn of my Gopro. To save the 18650 i want to use the battery electtonic of the original Gopro Battery. First I tried to use the 18650 without these electronic, and one result was that the last video file was corrupt because the camera had no chance to know the moment to write the final signat to close the video file. Now I used the whole electronic to runn the gopro by the 18650 and it works. but I dont know noting about the compatibility between the battery electronics of gopro and the match to the 18650. What do you guess about my construction and ideas? Will be the 18650 damaged soon?

[@jehugarcia]

+elaeroplano no i think you fooled the logic board, it doesn't know it has a bigger battery connected to it

[@frozenprakash]

Power = Voltage x Current W = 3.7V x 20A W = 74 Energy = Voltage x Current x time W time = V x I x time W hour = 3.7V x [3000 mAh] W hour = 3.7V x 3 Ah Wh = 11.1 That simple. And for reference, 1000 Wh = 1 kWh [1 Electrical Unit], which is what our kWh energy meter uses in home ________________________________ mAh and Ah which are seriously flawed unit (which doesn't take voltage into account), which is normally used by manufacturers and marketers to misguide people !! Professional and universal unit for energy are, kWh or Wh. I mean, these all of us use kWh meter in home, kWh in Tesla car, and 1000 Wh = 1 kWh. (how else simple do you want ??) Still people use mAh and Ah, wonder how lame can they get !!! And for comparison (different rechargeable battery types): AAA [NiMH] = 1 Wh AA [NiMH] = 2.5 Wh AA [Li ion] = 3 Wh C [NiMH] = 5 Wh D [NiMH] = 10 Wh 18650 [Li ion] = 8 to 13 Wh (high drain to high capacity) 26650 [Li ion] = 14 to 18 Wh ______________________________ Average energy of Tesla battery are around 11 Wh [18650], and to make a Tesla P100D [100 kWh] Model S, = 100 kWh / 11 Wh = 100, 000 Wh / 11 Wh = 9091 batteries or in simple words, 9091 [18650 battery] x 11 Wh = 100,000 Wh = 100 kWh. ______________________________ So i would seriously recommend 18650 enthusiasts to use Wh and kWh [our universal unit] instead of flawed mAh and Ah which are way too childish unit for energy !!

perfect thx

[@dirtforce0897]

nice job... so what is with the little fuse wires? will they not burn up during high amp draw? I'm trying to figure out how to build a 18S42P pack for high drain 300A, how do you figure out what size of bus bars to use? would thin nickel plate work?
