Very nice build! I like your practical approach using what's available and your clear methodical explanations. It's been a year now since you made this video. Would you do anything different now? I see that some of the manufacturers are making bigger batteries now. Would you use them instead?

Thanks. I just made a different ebike and I did it a little bit different. The principle is the same. It's just a little bit more elegant. Here's the link to the video: kzfaq.info/get/bejne/atVgl6Whvsm7p3k.html

I had the very same concept idea. The only issue is.. i intended to dedicate the batteries for a bike, running x2 20v in series makes the "40v" a headache to charge.. to use the original charger you must remove. So if was just using x2, x4, x6 etc 20v you can just use the original charger (making the bike plug in) .. but if you have a suitable 40v charger then you're flying.. just plug it in, done.

The tool batteries have a lot higher discharge rate but similar capacity to laptop cells. You may need 10 times the laptop cells to get the required amperage to run the motor but it will also give you 10 times the range.

i think this is a great idea, no matter what anyone say, their only what about 4ah not the best but hay if it works great, better then taking them apart and never being able to use them for your tools

@vuaeco 7 жыл бұрын

Thanks and yes, that is my main goal. When I'm riding my bike, obviously I can't use my tools. But when I don't ride my bike, I can just remove the batteries and put them in my drills/tools and start working. And sure it's only 4Ah but if you have many of these available, you can just stop and swap them out in seconds and keep on going (indefinitely-at least in theory)! By the way, at this moment, Dewalt and Milwaukee have 9Ah batteries available already!

@rayleclair7133 7 жыл бұрын

wow really they now have a 9a battery, this is really good because a 12v 12ah is is about as high as you can go with the small batteries, they do have a 15a, but for a power tool 9a is pretty darn good, and like you say, if you have 6 of these that will make 12ah, but 9ah this is new to me for a power tool battery, you did really good on saving and using your power tool battery, and the way you have them slide into your box like that, is amazing, good job, this is one of the best ebike fix i've seen so far, 6 of these will get you a long way, now all you need is one more box on the other side of your bike and carry extra batteries. Power tools have a very high discharge rate witch means more power then a gel acid battery

15 miles on two 5ah that's really good, but these batteries are made to last in your tolls so in the long run their way better then most batteries, most ebikes now are brushless motors i only wish they would do them vacuumes brushless, there way to load.

What an inspiring video! Good job man! But can someone tell me..... surely the hub motor being 36v would require the battery's to have a nominal capacity of around 10 amp hours? The ones in the video are 4 amp hours and running them in series only doubles the voltage right? Sooo my question to anybody who can answer is... does running an ebike motor under the stated nominal amp hours damage either the motor or battery's or does it just limit range and performance? Cheers

Thank you very much for creating this video. Is there any concern about bypassing the battery management system built into the battery packs? This is what is holding me back from doing the same thing. My motor is 36v, 1000 watt, and I don't want to ruin my expensive Milwaukee battery packs. Is there a way to add a BMS to this rig? How much can I discharge the packs without hurting them?

What 18v battery configuration would be possible for a 48v motor? 3 in series would give me 54 volts, would that be an issue? thanks.

@rjesparza 5 жыл бұрын

2 "20v" battery, 1 "12v" battery, all in series. Just make sure they all have the same capacity (2ah 20v, 4ah 12v). If one battery has a smaller capacity it will die first and possibly get damaged. Reducing the overall capacity) This is why a 54v setup is better. Also if you have a 48v motor, it will usually work fine with a 54v battery pack.

Why having fixed metallic plug for the + and - of the batteries? maybe having thinner metal plates at the end of a longer flexible cable (like car battery cables) would allow you to have any of these battery in any + or - sides as you can then fit these plates any way you like? It would give you more flexibility.

@vuaeco 6 жыл бұрын

Cables would work but you will need to find a way to secure them as they move around a lot when the bike is moving and going through bumps, pot holes... It's not good for a controller when it's being pulled at 30 Amps and suddenly gets disconnected under load.

Here's a suggestion, if you use a big bridge rectifier on each battery casing you can also use the reverse polarity batteries without reversing the poles as long as the batteries are connecte to the ac side the rectifier will correct the polarity on the dc side. It's like the old nintendo NES that works with either polarity because it has an dc rectifier inside.

@ vuaeco quick question: you have a fuse for the setup because you don't have the on/off switch from the throttle?

@vuaeco 6 жыл бұрын

On the upper right side of the box in the video, that is my switch/circuit breaker. I also have a fuse in line with that switch if you watch the whole video, you'll see it.

@gordocar3520 6 жыл бұрын

@ vuaeco to clarify: I bought an e bike kit that has the throttle, controller, and the hub motor wheel (like in your unboxing hub motor wheel vehicle) and the throttle handle, which is a Twist throttle has the on and off switch. I wanted to know if you have the same setup in this video with an ebike kit and if you have the on and off switch with your fuse box for extra safety. PS. I usually watch your videos over and over 😉 Thanks in advance

@vuaeco 6 жыл бұрын

Yes, I have similar setup for that ebike kit. Watch this video: kzfaq.info/get/bejne/idyeebhkuLW6emQ.html. At 13:31 I have the disconnect switch that also has a built in fuse. So it acts as a switch and a fuse. The controller has a power cable and every time I plug it in my battery, it sparks really bad to a degree it almost melt my XT60 connector. And every time my battery is depleted, I have to remove it to charge it. Then I have to plug it back in when it's full. And when I plug it in, it sparks again. So the switch/fuse helps take the spark every time I plug in my battery.

I would add two small panel voltmeter to indicate when either battery bank needs to be recharged, and I would not leave these batteries stay in the bike indoors unattended; after a ride they should be removed from the bike and placed in a factory regulated charger. despite the fuse, there is a small chance of a short that circumvents the fuse which could overheat the batteries and no chances should be taken, remove the batteries from the bike when not in use

Hi. Could you tell me the spec of that circuit breaker you used? And why a circuit breaker and a fuse?

@vuaeco 8 жыл бұрын

It's a 63A DC circuit breaker. It is an overkill and not necessary. But I needed a switch to turn it on and off because my bike controller seems to have "vampire" power sucker when my bike is not in use with my batteries installed. The fuse is 20A and it is necessary.

@JohnSmith-tp6xb 8 жыл бұрын

Thanks for the reply. What is the volt and watt of your motor and what is the volt and amp of your battery? I want to see if it matches mine to use a 20 amp breaker/fuse. I have a 48V 1000W motor and 48V 15aH Lithium.

@vuaeco 8 жыл бұрын

I have a 36V 750W motor. So in theory I would need a fuse that is more than 20A. But that's the only fuse I have right now so I just have to live with it. And it seems to be no problem. In your case, your motor alone maxes out at 1000/48 = 21A. So I guess 20A fuse would be fine as usually a motor would rarely get to its maximum rated power. I would use a 25A fuse if possible in both cases.
