Milwaukee M18 DIY eBike - Power for Miles!

[@kansaIainen]

Excellent! I installed two Milwaukee 12 AH batteries today and went for a test drive. After about 16 kilometers (10 miles) of driving on a dirt road, the batteries still had three lights left! The only drawback is that the batteries almost could not fit in the housing intended for them.

[@jaredstlouis5435]

I run 4 12ah m18s in series for 84 bolts on my fat e bike I get 36mph and 40 miles for the last 3500 miles and have saved a ton

[@35sleepy]

How have the battery hold life on them?

[@chrischung2365]

4 12ah batteries get you just 40 miles range?

[@dickdickling9389]

​@@chrischung23651x 12ah is 216wh making for a total of 864wh. Roughly means he got 43 miles best case scenario, most say round 20wh per mile. 40 miles for a bike is plenty, if you need more, then take a bus or car especially in america. For me in europe its 5x morning commutes to work. Big reason why bikes are popular here.

[@andrewisemailingyou6220]

Not how voltage/watt hours work... Wiring in series, your "90 watt hours" will remain 90 watt hours. Series only doubles voltage, parallel doubles amp/watt hours.

[@manorin]

I'm doing a similar setup with two 8.0 High Output M18s in a 36 Volt configuration for a scooter, however I'm noticing that the batteries are going in what Milwaukee calls shutdown mode( single flashing led) if, I suspect, pull more than ~12- 20 amps. The batteries still have plenty of voltage left , but if they were in a normal tool, The tool would be told not to turn on by the battery, but because we are using direct power taps, the batteries still output the power. Putting the batteries into the charger "Resets" the mode and it's a fully functional battery again. I wonder @14:10 even though you ran the batteries low the battery status was similar to my situation

[@CarsandCoding]

Excellent video! I am thinking of trying this as well, but I have all Ryobi batteries so the mount is a little more of a challenge but I think it’s doable.

[@toptiergarage7378]

100% doable. The stems make it a little bit more bulky. Plus the ryobi batteries have a voltage cut off in the batteries themselves so you can't over discharge them.

[@nathangant7636]

For a 36v motor, I'd just go for a Ryobi 40v 12aH battery, or the smaller 8aH / 6aH sizes and avoid a 2s battery setup. For connectors, I went from XT60 to the Anderson powerpoles. The newer Bafang motors use 45 amp Anderson connectors instead of XT60s. . Much improved contacts, although an Anderson crimping tool is best for completing the wires.

[@danlux4954]

You’d probably need a voltage regulator

[@saltysteel3996]

The DeWALT 60V Flex volt bike is even better. Lol :P

[@toptiergarage7378]

Who knows maybe we will hook one of those up next 😁

[@smokefentanyl]

@@toptiergarage7378 hook up a solar panel and a crap ton of flex volts lol , ultimate long range meth mobile

[@ruufiss9922]

Do any of yall think it would be plausible to add a brushless motor from on of the tools onto a bike as well. Just a random idea I had

[@rman176]

Thanks, I got four 9 ah m18’s. Any good links for the motor kit etc?

[@Popajaja]

I have acquired 6 pieces, very cheap (10-20% of the new price) almost new 12Ah/18V Milwaukee batteries and I want to install them in the E-bike. The problem is the adapter is made of cheap plastic, most likely ABS, not polycarbonate (PC). or fiberglass nylon How did you ensure that the batteries do not discharge below 2.5V per cell and thus destroy them? Another problem, how to secure batteries against theft??? Greetings from Switzerland

[@fixer2u]

Awesome, I actually made a similar video last year except mine was a Trike! I have never range tested mine, but my top speed was 21mph on flat ground.

[@nickrutyna3618]

So I hooked my son's hyper 350 the way you did. Both 6.0 Milwaukee batteries were fully charged. After my son's first ride he checked the batteries and they were flashing only one cell. Have you experienced this before. The batteries are brand new.

[@monkeyslap]

I love this idea!

[@theupscriber65]

Need a handkerchief?

[@arnemitchell1138]

Do you need to wire in BMS or do the batteries already have BMS?

[@robbysue90]

Can this range be extended with a partial power output with pedal assist?

[@philipdove1705]

Great video I'd like to make a work bike powered by Milwaukee. Can you make the same setup for an electric boat motor using m18 or Milwaukee mx batteries?

[@timstacyTR]

Love the video man in your personal opinion do you think you could run m12 and m18? like 12+12+12 is 36 18 x18 is 36? am i crazy? lol i have ALOT of milwaukee batteries

[@jamesdeegan7365]

the crazy part is milwaukee makes 12amp batteries, you are useing 5 amp batteries

[@35sleepy]

Any problems with the battery's? I've read comments on other videos people burning the battery's.

[@markhuru]

Need an up date on new high output batteries

[@robbysue90]

Curious, I would love to add these to a nicer bike setup. Do you think it would be possible to add the motors to a higher end wheelset?

[@MikeNBikes]

When you said nine mile range, is that with both batteries at the same time or nine mile range with one battery? And what app did you use on your phone to get those ride statistics? Also at the end when you show the ah with wh. How you list 2ah and 6ah, is that 2x batteries at 2ah is 4.27 miles? Or is that with 1x battery? Then how you list 6ah, is that with two 6ah batteries?

[@jimmywarren6685]

It has to be both batteries...remember...have to have both batteries in order to get the 36volts to run the motor.

[@burkeadam]

I'm a go with the MX platform

[@imsoz7741]

How fast will I go with one 1.5ah 20v 27wh drill and how far plz reply I just got it

[@tedshredhard23]

Any suggestions on controllers or other parts?

[@greywolf2809]

Sweet can you make a mid drive from a skill saw?

[@chrisd5383]

So there’s no over voltage protection to run 36v?

[@billcorbitt7642]

Do you have a video of building the bike?

[@gregorykaiser2474]

I got a e bike kit on the way and 4 DeWalt 18v batterys any ideas

[@guillaumebelzile4715]

Whats is the W or the hub motor?

[@Iinustechtips]

Do makita batteries have over discharge protection?

[@lukie4ever]

The newer 5 and 6ah ones do, i run 3 5ah in series witch makes 54v 5ah and when they run low they automatically shut off Edit I meant i use the batteries on my ebike

[@benaiahhatfield3548]

Why can't you just wire the battery straight to the motor? Did you do the power wheels adapter just because it's easier?

[@farmerchad62]

The power wheels adapters just make it super easy to remove and replace the batteries for charging. This way, you can use the Milwaukee charger that comes with your tools, even keep spare batteries in a backpack with you. You really wouldn't want to do this any other way.

[@benaiahhatfield3548]

@farmerchad62 I did it without the adapter and it worked perfectly. But thanks for the tip.

[@jakefriesenjake]

​@@benaiahhatfield3548you still are running it into a controller and then the motor?

[@dragercustombuilds6107]

Ziptie pro no don't use a pipe wall strap

[@nin1ten1do]

17+-Wh per mile is pretty good.. werry same performance as high grade e-skates.--.

[@donnaquatrale6599]

I wonder what 3 in series could do?

[@HondaFit4Adventure]

Melt the wires...

[@petermclaughlin3292]

I could do this well without the Batteries with A well tuned and balanced bicycle not as fast but the distance. Pedaling is not that bad.

[@JustYourAvarageJoe]

Just put it on a 54 or 72 volt system 3 or 4 battery system lol

[@masalicio]

I do have a pair of 12amp M18s.... Hmmmm! :)

[@toptiergarage7378]

That will easily take you over 20 miles 😂

[@ccarmelo1979]

We purchased this Vivi 27.5” electric bike and a Tentaquil 26” electric bike for our 13 and 14 year olds. kzbin.infoUgkxUiL0GnyDjP32RJdd660sP8mZk4CRLTCJ The Vivi was much easier to put together. With the Vivi, there was a video link to assist with assembly which made the process easier to follow (we did put the handlebars on upside down, but it was a quick and easy fix). With the Tentaquil, the assembly was not as simple to follow, but after we messaged the company for an assembly video, it was easier and they did respond quickly. The other major differences were that the Vivi has a grip throttle on the right handle (like a motorcycle) and the Tentaquil has a push throttle that you use your thumb to activate. The monitors were also different, so if you’re looking for something specific in terms of changing the bikes functions, pay attention to what the monitor offers. We were really impressed with the overall quality and functionality of both bikes, but if you’re looking for more power and an easier assembly, definitely go with the Vivi!

How to wire m18 batteries for a 48V motor?

[@andytrace]

Did you ever figure this out? That's what I need 🙏

[@danlux4954]

Probably 3 in series with a voltage regulator.

[@Mantis858585]

@@danlux4954 yep

[@Mantis858585]

Answer, wire three 18v milwaukee batteries in a series with an 18v to 12v step-down regulator.

[@kristophertravis7160]

You didn't show how to wire the battery to the bike

[@mpcarlin11]

At the beginning of the video while he was building the battery pack, he points to the plug, the plug will just go into the motor controller.
