How to Build Battery Pack without Soldering ,the Simplest Way

Oh he definitely did something right,made a fireball waiting to happen!!😂😂😂

The reason the voltage is sagging soo bad is because of the epoxy!! You can get a cheap spot welder for $50 or less and then weld nickel strip to those 21700s. The copper you are using is great but it's nearly impossible to weld copper to batteries. I promise you though, clean all of that epoxy off those batteries and weld 0.15 or 0.20 nickel strip to those batteries and your scooter will have double the power. Hope this helps!! Take care and be safe. Aaron

We need more ppl like this guy ,honest in what his talking about.this guy dosnt make a video for us to start fires,he makes and shares of the knowledge he knows .good on you bro,

And we wonder why there are so many Battery Fires, That Video is a perfect Example on how not to build a battery pack, And this is why we can no longer take E Bikes and Scooters on trains and Buses because of fools who think they know how to build a battery pack with out any safety built in, not even an inline fuse or breaker unbileveble and this is why the goverment clamp down because of fools who want to do cheap short cuts and put everyone els in danger and mess it up for every one at this rate they will be doing a goverment electrical test on all E Bikes and Scooters each year Hope your Proud of yourself, Teaching people on how not to built a Battery Pack.

You can install a fuse, or a breaker to protect from over current to protect the battery from shorts down the line that could happen before the speed controller. You can install a temperature control switch with a probe inside the pack to cut off the power when things get too hot... or even just a temperature display on the handle bar.

It's the characteristics of the cells that you've chosen that give you the significant voltage drop. It's the discharge rate of the cell that matters as well as the number of cells in parallel. The more cells in parallel is not necessarily means less voltage sag. 15 cells in parallel with a discharge rate of 5A aren't necessarily better than 5 cells in parallel each with 20A discharge rate. With the 15 cells in parallel each 5A maximum discharge rate, you will be able to build a battery pack that can discharge 75A maximum. While with the 5 cells in parallel each cell with a discharge rate of 20A, you get 100A maximum of your battery pack. You should have a safety factor though and not use the maximum discharge current totally out of your battery pack. I'm with those who say a BMS is a must in those battery packs. A good design for a battery pack takes into consideration a lot of factors. Thanks for sharing your experience!

BMS is a must!

Enjoyed the video . Can you suggest a reliable seller for the battery cells . I've tried a few people and they were not what they were supposed to be. Thank you

Ive mixed graphite powder with a standard epoxy to create my own conductive epoxy to repair a broken circuit on a Ford spark control module

Using the copper plate is a good idea but instead of epoxy you could have used solder paste, you'd still need a soldinging iron, you can run these using any inverter since you only need 200w max, you are correct that you dont need a bms but you need some ways to monitor the voltage from each cells, the wires you are using looks like 4mm wires which is about 40 amps max. you need 10mm cables.

Such a great idea! 👏How much did all that silver epoxy cost you? How long did the copper continue to stick to the batteries after the road vibration?

I use battery good quality 18650 battery holders, then thick copper solid conductor to solder between the battery holders

Just use a controller that draws less amps. An 18 - 22 you will not have a problem and have good range with a 72v. If you say the battery is 12a and 30a continuous and your controller is pulling 50a under max load. I have a 60v battery that is 16s8p its 20a and 30a continuous. I use a 30 amp controller no problem and great range. If you are going to over discharge your battery with that load a BMS is a good idea if it has current draw protection.

So ibcan easy remove faulty cells for maintenance

Can you explain why BMS is not needed in more detail in a different video? I find your videos actual gold. You explain everything very good

I answered and said, "If I have found favor in thy sight, O Lord, show this also to thy servant: whether after death, as soon as every one of us yields up his soul, we shall be kept in rest until those times come when thou wilt renew the creation, or whether we shall be tormented at once?" 76 He answered me and said, "I will show you that also, but do not be associated with those who have shown scorn, nor number yourself among those who are tormented. 77 For you have a treasure of works laid up with the Most High; but it will not be shown to you until the last times. 78 Now, concerning death, the teaching is: When the decisive decree has gone forth from the Most High that a man shall die, as the spirit leaves the body to return again to him who gave it, first of all it adores the glory of the Most High. 79 And if it is one of those who have shown scorn and have not kept the way of the Most High, and who have despised his law, and who have hated those who fear the Most High -- 80 such spirits shall not enter into habitations, but shall immediately wander about in torments, ever grieving and sad, in seven ways. 81 The first way, because they have scorned the law of the Most High. 82 The second way, because they cannot now make a good repentance that they may live. 83 The third way, they shall see the reward laid up for those who have trusted the covenants of the Most High. 84 The fourth way, they shall consider the torment laid up for themselves in the last days. 85 The fifth way, they shall see how the habitations of the others are guarded by angels in profound quiet. 86 The sixth way, they shall see how some of them will pass over into torments. 87 The seventh way, which is worse than all the ways that have been mentioned, because they shall utterly waste away in confusion and be consumed with shame, and shall wither with fear at seeing the glory of the Most High before whom they sinned while they were alive, and before whom they are to be judged in the last times. 88 "Now this is the order of those who have kept the ways of the Most High, when they shall be separated from their mortal body. 89 During the time that they lived in it, they laboriously served the Most High, and withstood danger every hour, that they might keep the law of the Lawgiver perfectly. 90 Therefore this is the teaching concerning them: 91 First of all, they shall see with great joy the glory of him who receives them, for they shall have rest in seven orders. 92 The first order, because they have striven with great effort to overcome the evil thought which was formed with them, that it might not lead them astray from life into death. 93 The second order, because they see the perplexity in which the souls of the unrighteous wander, and the punishment that awaits them. 94 The third order, they see the witness which he who formed them bears concerning them, that while they were alive they kept the law which was given them in trust. 95 The fourth order, they understand the rest which they now enjoy, being gathered into their chambers and guarded by angels in profound quiet, and the glory which awaits them in the last days. 96 The fifth order, they rejoice that they have now escaped what is corruptible, and shall inherit what is to come; and besides they see the straits and toil from which they have been delivered, and the spacious liberty which they are to receive and enjoy in immortality. 97 The sixth order, when it is shown to them how their face is to shine like the sun, and how they are to be made like the light of the stars, being incorruptible from then on. 98 The seventh order, which is greater than all that have been mentioned, because they shall rejoice with boldness, and shall be confident without confusion, and shall be glad without fear, for they hasten to behold the face of him whom they served in life and from whom they are to receive their reward when glorified. 99 This is the order of the souls of the righteous, as henceforth is announced; and the aforesaid are the ways of torment which those who would not give heed shall suffer hereafter." 100 I answered and said, "Will time therefore be given to the souls, after they have been separated from the bodies, to see what you have described to me?" 101 He said to me, "They shall have freedom for seven days, so that during these seven days they may see the things of which you have been told, and afterwards they shall be gathered in their habitations." 102 I answered and said, "If I have found favor in thy sight, show further to me, thy servant, whether on the day of judgment the righteous will be able to intercede for the unrighteous or to entreat the Most High for them, 103 fathers for sons or sons for parents, brothers for brothers, relatives for their kinsmen, or friends for those who are most dear." 104 He answered me and said, "Since you have found favor in my sight, I will show you this also. The day of judgment is decisive and displays to all the seal of truth. Just as now a father does not send his son, or a son his father, or a master his servant, or a friend his dearest friend, to be ill or sleep or eat or be healed in his stead, 105 so no one shall ever pray for another on that day, neither shall any one lay a burden on another; for then every one shall bear his own righteousness and unrighteousness." .....2 Esdras 7:75 ////////////

Haters used wet hands to hate on this technique

Important Disclaimer This battery pack failed after 1 month of use as the silver content in the silver paste epoxy is fake. It was not real silver nor did it have any purity. Most places carry fake silver so be extremely careful before buying this kind of product. God told me that if this had real content of silver it would have worked fine on the battery build, exceeding the performance you get from pure nickel stripped battery pack in terms of delivering the current in efficient and effective way. Unfortunately God told me you won't be able to get real silver content on these epoxy so just go with the spot welding technique on the pure (or near pure) nickel strip which can be found on internet if you look hard.

10s4p carries my fat ass at 25mph 😊

Hooke has made a 3S battery, do I have to take it in the car or train because I charge my mobile in it?
