60v 40ah mega range battery DIY build

I built a 60v 40ah ebike battery DIY for my son's 5000w ebike max out put is 320a and it's a triangle battery for a ebike

[@kevinduprey9326]

Great Job... People need to realize that building packs yourself from reputable USAbattery dealer is peace of mind. Rewraped batteries from china are very common. The china manufacturer might not check specs from their supplier and unknowingly sell inferior product. Ive been vaping for 10 years and educated myself on these batteries. Many times people will have their pack go bad and all it takes is one or two cells to do it. You could have 90% still working and throw away a battery when all you needed to do was rebuild it. Having the skills that ebike guy has, and willing to showing you is invaluable. I Just started learning this ebike stuff FIRST then im gonna get one started. This channel is my go to spot. Thanks...

[@E-bikeguy]

Oh yeah, I've learned the hard way so now I get all my cells from 18605 battery store.com

[@tarstarkusz]

But the problem is he is building them without a BMS. It's fine if you don't run the battery down a lot, but if you do, it is very easy for a few cells to drop below the other cells.

[@Apeshoot13]

Awesome info. I ended up getting a super steal on a GoGoBest GF700 instead of the Eahora Romeo. Too much $. It's dual 500w hubs at 48v. I put 115 miles on it the day after I got it with 167 miles on it from the first owner. I added another 20ah 48v in series and another 20ah 48v to swap in. I was using my bike trailer to carry the extra batteries, but switched to a backpack that is way too heavy to ride with. I am planning on making a hilly 100 mile commute. 50 mi each leg. I made it 52 miles one way before the batteries were all tapped out. The mistake I made was moderately pedaling and juicing the throttle to much for over 3/4 of the first leg of the trip. What mods can I do (controller, diff battery setup) to make this more efficient? To recap, I have the stock GF700 plus two 20ah 48v. One in series and one to swap in. I plan on making a video review with my current setup, but I wanted to see what your thoughts were. Thanks In Advance.

[@E-bikeguy]

Nice and one heck of a trip, well the only thing that I can suggest is if you can one battery with hi capacity, because them extra batteries are heavy because of the case they in which is wight you don't need , then you will run more efficient

Where can I get more information on that 60 volt 40ah battery that DeWalt is coming out with? The internet is showing nothing

[@bernardhfox]

Had a few questions. Is the device that the battery plugs into on the bike, the BMS? Is it the device or circuit on the bike electronics that keeps the battery from over discharging, and does it also keep the cells in balance? And is the rider responsible for knowing when its time to charge or does the system on the bike say, hey battery too low?

[@E-bikeguy]

The bms is all a safety device that monitors the battery condition

[@keithballard4621]

I don’t use a bms either. Here’s something I saw a few years back and Iwant to share it.. Get some 3/4” thin wall pvc pipe for 18650 cells, 1” for 26650 cells. Get button cells for better contact, or put small magnets in between the connections .No wires and no nickel strips needed… just stack the cells inside the tube and allow room for the end caps to screw down and tighten them together.drill holes in end caps and add small nuts/ bolts with matching electrical eyelets for the parallel connections.I charge and check each cell for balance before sliding into the tubes. I extract them for occasional balance checks by using a telescopic magnet to pull them out the back end of the tube. I’ve used several variations for quick disconnects but won’t go into all that. Hope you get the picture.

Glue gun snot. The sign of a quality build everywhere........ You do everything else ok then do that. Please for the love of {whatever} use cell separators, they hold better and allow airflow stopping a hot cell heating it's neighbour and in the event of a bad thermal event it slows the spread.

It's crazy just how much work goes into making a battery this big, always knew it was a timely job but didn't realise it was this labour intensive. Makes me wonder how many cells are in my 'tiny' 52v20ah triangle battery... The more I watch battery build vids the more I want to make one myself, but to be fair I don't have the electrical confidence to attempt it... Damn, I cant even wire up my frickin sabvoton 7245m to my stupid voilamart kit, really mad with myself as the damn controller cost me £180 and I feel like ive just wasted my money

Ih man sorry to hear that what you having trouble with. I'll make a how to video

[@mickyb.8014]

@@E-bikeguy it's a Voilamart Kit, when I wired it up the throttle I twisted and when the rear wheel began to spin the goddamn peddles spun forward too whacking my leg (which really damn hurt and I was hopping round my kitchen cursing like hell 😂 lol) but I couldn't work out why the damn freewheel cassette was locking on, 'cos in effect Tommy I think that's what it was doing, it seemed 2 x as powerful as the stock 30+1amp Voilamart controller but the damn peddles spinning at the same time as the wheel scared me so much I had to put the old stock Voila controller back on... I've since done the shunt mod on the Voilamart controller and it's better but it's bugging me that I'm stuck with this Sabvoton controller that I can't figure out... I bet if you were here it would be on in no time lol... I'm gunna keep watching more controller vids to see if I can figure it out.. I'm wondering does the RED wire from the "48V-72V Light Power" lead (off the Sabvoton controller) have to be connected to my battery Red positive wire? Also is the "Low Brake" wire the purple/black wires do they need to be connected to my brake levers to cut off the rear wheels power when braking? The wires I'm not using will be.. "Alarm"(it's not capped off, should it be?) "Reverse 0V" "E-ignition" (this has a cap on it) "Speed Limit" (the 2 blue wires) I put a small switch on these wires on my other controller so I could put it on these wires.. The wire/s I'm confused about is the Red&Black 48-72v Light Power The "Pas" I ain't decided on yet but it's not a probs as I know how the wire this, also the 3 red,white and black "throttle" wires I'm fine with as I think my throttle is red, green, and black and I'm sure the white wire goes to the green, and red to red, black to black... It's the "48-72v light power" I'm confused over (and possibly the "alarm" as it may need capping off?) I'm not sure if I seen some KZbinr saying the red wire (off the 48-72v light power) has to be wired direct to my batterys positive (red, I think) wire but it's a slightly thicker gauge wire (but not 10gauge like the red,black(battery) and green, blue-purple,yellow motor phase wires as these are the 10gauge(I think) thickness... Just got me super baffled as to why when the rear wheels turning so are the damn peddles cos if it happened when doing 30mph it would snap my legs and probably kill me😢

[@E-bikeguy]

@mickyb.8014 It looks like you have everything right but the freewheel might be locked up, the peddle only spinning if the motor is turning in reverse

[@mickyb.8014]

@@E-bikeguy erm, ok I'll try rewire it all up again, maybe just maybe my eyes were playing tricks on me but I could've sworn the wheel was turning the proper way to propel the bike forwards (...but you might be right, I may have to change the phase wires (the 10 gauge yellow,green, blue) to instead blue to blue, yellow to green, green to yellow until I somehow get it to work... Think I'll attempt at the weekend when I've a spare 4-5 hours cos I've wrapped all my wiring up with electrical tape it literally takes about 1-2 hours just to carefully unwrap it all without damaging the wiring 😂 lol... Cheers Tommy I'll let you know how I get on over the weekend... Also do I need to run the red wire (of the "48-72v light power" controller wires to the positive on my 52v battery??? I wonder if I needed to do this as I think I seen someone say you gotta do this on their vid, and what even is the "48-72v light power" wiring even for Tommy? I initially thought it was for wiring to front and rear brake lights etc? I just don't get what it means by "light power"?

[@flolou8496]

Amazing upgrade if not a little dangerous, but since your dealing with lithium ion cell's, can I ask an important question , since you might have a unique perspective on it: How safe is it to actually carry a spare lithium battery with you say on the rear rack? When I say safe, I mean safe as in the road vibration does not directly compromise the integrity of the cells and the battery catches fire (even if not in active use while the active battery still has some juice left in it ) It might seem like a dumb question to some people, but after I saw this video, where the E-scooters , (and some Ebikes) exploded and caught fire, even while ''parked'' sort of freaks me out, in fact in some of the fires presented, the batteries appear to not even be ''charging'' so why the hell would these battery's be dangerous just in a ''resting state '' and explode spontaneously without even in a charging state ??? see: kzbin.info/www/bejne/baHMpn18g9t6p9U Top 10 E-Bike & E-Scooter Battery Explosions Caught On Camera!!

[@E-bikeguy]

Well I will tell you this, my battery is in a case and where the battery rest on the frame there is extra padding to protect it from damage. I ride my ebike off road a lot and so far no problems 😊 so putting one on a rack shouldn't be a problem you will be fine

[@flolou8496]

So what do you think might be going on when you see even some of these batteries just spontaneous explode? The first E-bike explosion was just that, just there parked and appearing not even charging, (is it possible some of the cells can be of such poor quality, no extra pressure from the road vibration, or wrong electrical input is necessary, we've got enough crap to worry about in this lifetime as it is, without wondering if our Ebike batteries are ticking time bombs!) P.S. I personally do not trust the UL certification process involving E-bike battery's, but that's another topic for another day)

[@E-bikeguy]

@flolou8496 that's crazy, I think that one of the cells went into thermal run away due to low quality cell, then you have short not enough padding rubbing on frame , bypassing the bms then over discharging a battery, then using the wrong charger too. All this plays a factor in why a battery just go up in flames. You know? So when a person like me decide not to use a bms on the battery, you have to build the battery around the controller not the controller around the battery lol💯

[@salviaaable]

@@E-bikeguy ... sure the con. pulls not more than the batt allows.. can do it yeah but there is no short circuit protection bruh, even cheap BMS can read voltage of each Group. that's for LONGterm use. important when it goes to safety also no Temp. protection.... on someone whos already knowing what they are doin great but that is for your son ?? cmon man u shoud know better

I have a far driver 3000-4000w speed controller but evry time i open the throttle it gives a sligt kick stops and then goes in to undervold protection Beeps a few times and then i can give full trotle Any idea how i can solve this

[@E-bikeguy]

Probably need to adjust you undervoltage in the settings in protect column

[@Thefreakyfreek]

@@E-bikeguy i did that already I talked to some oter guy in your comment section and its probably the bms of the baterys i got It probably needs an enable pin or something

[@E-bikeguy]

@Thefreakyfreek oh ok I figured that also but I just didn't mention that might be in the settings but battery issue is definitely not ruled out.

[@Thefreakyfreek]

@@E-bikeguy thanks mate for being a clear spot on the internet were information is vage at best

[@Thefreakyfreek]

​@@E-bikeguyfound the problem Its simple Hook up a headligt so the batery sees some electrical usage

[@tarstarkusz]

I think you said you are 6'7. I'm a short guy next to you at 6'3. I recon you are around 250 or better. This bike did 54mph with you on it. Your kid will probably hit over 60.

[@E-bikeguy]

Yes definitely we did a speed run and he hit right at 60mph

At 45mph it can go 50 miles before it need charge

yo buddy nice count.. but damn.. no safety at all if one of those cell blow outz.. thst paralel THICK wire.. will help other to combust.,. use smaller thiner nickel strips as small (about4-6AMP) fuse conected to THICK WIRE to guarante yOu dotn blow out whole pack if one cell failed.. happy welding

[@E-bikeguy]

@nin1ten1do yeah well I still have it and broke it down to make a better one

[@nin1ten1do]

thx buddy.,. trust me some like bateryhookup.. cell level fuse will do you can join them to that big copper hunk with 100%safety for each cell.. you did overall good job i am just.. get mad about that 0 safety.. also heating cells over 65C can cause combustion.. stay safe bro..

What cells did you use? Seems like there is 2 different cells. Good build

Eve and molicel they both in the same capacity range, thank you the battery is performing great 💯

[@CapybaraMan420]

@@E-bikeguy oh, do they have the same discharge current too?

[@E-bikeguy]

@CapybaraMan420 no, lol so I calculated the eve cells discharge current of 20amps and got my total amount of discharge current the molicel are 35a cells but even the 320a just for the 20a cells the controller only can take 200a the battery still in the safe zone

[@CapybaraMan420]

@@E-bikeguy Looks like a great pack, smart on how you used the copper so it can handle the high amps. I have a 23S7P pack with LG M50lt 5000mah 15A cells. Im running it with a BMS though as its going in a electric motorcycle. Used 0.15mm pure nickel.

You should do 72 volts or higher

It's for my son's bike I can add to get 72v maybe later tho

[@user-ki8by1gf3i]

Hello again. I commented once before asking how much it would cost to have you build me a 3000 watt Ebike from my Bianchi center pull. I need at least 50 miles at full throttle over some very, very big hills for range, so I need to carry some capacity. I don’t know if you ever answered ma, as I forgot which video I left the comment on. I wish you had a small site like citizencycle has, and you could feature an area for potential customers to communicate with you. As far as my idea for battery storage, how about this? Advance Auto now sells dIe hard batteries, and for $115 with exchange you can get a 12 volt 45.6 pound marine battery. If you put that in series, I think, (I forget), with a $50 Amazon 36volt battery, using a Bolton parallel 2-Battery combiner, as described in numerous KZbin videos, you’ll have a 48volt complex battery (if this would (if this would work) with seemingly huge capacity. Is there a hole in my thinking? We’re it not for the limits of the battery combiner you could stack another 12 volt for more capacity, and maybe put them I a tiny trailor if you don’t want to load the bike more, or use a 48 volt battery in the complex to make 60, or 60to make 72. It sounds like this may fry the combiner, though. And it is only limited to a 30 amp controller, so somebody needs to make a more robust combiner. Your thoughts?

[@E-bikeguy]

Ok I hear ya email me at [e-mail] we can discuss more about a build

[@ebikeoutdoors]

Great battery man and instead of paintings the bike have you considered using heat wrap stuff ⚡🚵✌

[@E-bikeguy]

Yes I'm going to get some next week

[@ebikeoutdoors]

@@E-bikeguy nice one it's really good stuff I wrapped my ebike with it alot easyer than painting 🚵✌👍

[@bobikbobikowy5458]

Thats very risky to build that big battery with hot glue. Bicycle have a lot of vibrations. Hot glue will let go and battery will hold just on spot welds, and loose spot weld causes fire...

[@E-bikeguy]

Man lol it's fine trust me it's my son's battery and he rides his bike like a dirt bike and not a scratch on it, in order for hot glue to let go if the battery was actually dropped from a really high place and you need to take in to account that the nickel hold it together not just hot glue

[@bobikbobikowy5458]

@@E-bikeguydunno maybe you have better brand glue because when i used hot glue it was holding pretty bad. I made 10s battery and it let go in 2 places after few chill rides in forrest. Now i always use plasic holders
