DIY 1000w E-bike Phase Wire Upgrade! 72v 200 amp Sabvoton controller is Way Too Powerful!

[@ProspectorTripp]

Hello all, On my DIY mountain bike build the 1000w BLDC Motor Phase Wires were getting hot with the 72v 60 amp controller. Because I want to install a better, smoother and slightly more powerful Sabvoton 72v 80 amp controller, I need to upgrade the original 18GA Phase Wires with heavier 14GA wires that can handle almost twice the current. This motor mod is working great and the phase wires are now getting only slightly warm and not getting hot! Yahoo baby! The planned 80 amp controller is giving me a hassle so I decided to install my 72v 200 amp controller. This is a super powerful controller I bought for another project and certainly too much power for this very light mountain bike. Watch and see! 😂 Love to all Stay Golden

What a Monster you created you Crazy Racer -X-Man perfect for the Halloweenie events (and beyond). But your going to be feeling that test-run for a few days/weeks. Buddy, Hope your Recovery goes smoothly, and it acts as a reminder that were not as young as we once were, (things take longer to heal). With that being said... It's alive... Alive... ALIVE I say!

[@ProspectorTripp]

I’m at the Pharmacy getting my flu shot 💉 now that’s really dangerous 😂 My recovery is complete! 😃 I’m ride ready now! But I’ll be dialing down that controller to a manageable power level. So powerful you gotta lean on it.. or else ☝️😅 Thanks Johnny but I’ve finished convalescing this morning 😂 Peace Prospector Tripp

😂 it’s crazy fun and slightly dangerous! ☝️😵‍💫 Love to DIY! Thanks much Jason, stay safe and healthy.. and please don’t follow my bad example of no safety gear. No worries I’m still alive and well! 😁 Peace Prospector Tripp

[@Gamer.brucelee.kungfu]

I am glad you all right (not injured). Video great.

[@ProspectorTripp]

Yeah me2.. Butt was bruised and elbow scraped.. not too bad. Yeah, that 72v 200 amp controller is wildly powerful. Surprised me 100% 😆 This bike is now running a 72v 60 amp controller and is a joy and ride. The 1000w motor at 72v 60a definitely gets slightly warm but not hot, and the phase wires never get even slightly warm. Success! Thank you.. stay Electrified! Peace Prospector Tripp

I recommend not doing that wheelie crash part 😂 luckily my bike and I are both doing well. Thanks Brian stay safe Peace Prospector Tripp

Great job PT , That stuff is way too technical for me to tackle . And probably just as well , because i thought you were about to take off , but there are no wings on it , lol . Wow !!!! hope you're OK , Take care , and keep it safe out there , like Keith Bowen always says , 👍🙏 Cheers Ned ,

[@ProspectorTripp]

Hello Ned, I’m good as far as the crash. I went riding around yesterday on this Light Rocket.. of course, after I programmed it for 1/2 power!☝️ It’s still too fast and crazy scary for my taste. I’m changing out the controller for a more reasonable amount of power. Thanks Nev, Peace Prospector Tripp

[@mikepung94]

When you started with the extra power, I was wondering if this prospector was going to Tripp! Yup! Glad you are okay.

[@ProspectorTripp]

Made it again! 😅 Have a nice Tripp, see you next Fall 😁 Thanks Mike Peace Prospector Tripp

[@Ltn.Immelmann]

Voltage = resistance x current. U=RxI My old brain is starting to work again 😆. I understood what you were doing. Hot cables melt and cause short circuits. Howdy Matt, that was good work 👍🤠

[@ProspectorTripp]

Hello Peter, I just finished power modding my battery, a very powerful battery along with this 200a controller is Way Too Powerful for this little bike! Surprised me 100% 😂 Don’t worry I am just fine! Peace Prospector Tripp

[@davidhazel36]

Interesting build 👍

[@ProspectorTripp]

Smoked this one ☝️ 😂 I modified another one, ventilated and potted this next 1000w and it is still going strong 💪 Peace Prospector Tripp

[@robertmcfadyen9156]

The weak point in the 200 amp setup is that at full power , the field coils will fail during sustained operation in hot weather . I have seen a 14000 watt e - bike overheat on a freeway during a hill climb in the mountains from the car . The motor was smoking and the rider wasn't aware of it . A bit like overloading an electric drill .

[@ProspectorTripp]

That 200a controller is coming off and a more sensible 7280 going on. The motor may smoke anyway? We will have to see a bit later. Thanks much Peace Prospector Tripp

[@mshinn13]

That thing is a beast!! I have a no name brand fat tire Ebike, would love to upgrade to your setup but I could never pull it off. Side note, I work with Gordon Smith, said you guys grew up together in Michigan.

[@ProspectorTripp]

Yes sir, Lance is a co-contributor to the wheelie crash 😂 we did everything with gas back then.. but it’s still the same concept. Make it light and fast! Glad you have a ebike too. As far as upgrading. Just upgrading the speed controller to a more powerful one is fairly easy and a huge improvement. You can check your speed controller and see what amperage it is and the physical size. There are many available on eBay and Amazon that are fairly inexpensive. Less than $100 As always read and study so you are making a good correct choice. Thanks for commenting! Tell Buzzy (Lance) thanks! Peace Prospector Tripp

Very cool, maybe hold off on any longboard electric designs :) I saw a while back a guy on a long board shooting around thirty plus mph, I was like dang

[@ProspectorTripp]

Hello DDI, I originally bought the 200a controller for another build. It’s at least 2x too powerful for this bike. I’ll be working on the 72v 80 amp controller. Very soon! Thanks much Peace Prospector Tripp

[@mackattack8627]

Thanks for sharing i,ll custom build those Qs 205mm motors to match the same power as the mighty 272mm now that I can see the shaft can be Bored out a bit to accept bigger phase wires in my case I need 7-6 awg to handel above 300 Amps I noticed in the last 20 years that green phase wire lamination in those Outrunner / Hub motors from Qs always melt in time Nevertheless i,ll add forced air colling to the motor cases to cool the entire Stator ✌

[@ProspectorTripp]

Wow.. 6ga, that’s huge phase wires. This motor I smoked.. 😂 that sometimes happens 💨 when testing the limits of reality ☝️ I replaced with another 1000 watt motor that I am limiting my power to 1400 watts. I potted it and ventilated it. So far it’s Golden 🤠 Stay on it.. Zoom zoom! Peace Prospector Tripp

[@mackattack8627]

@@ProspectorTripp yes sir above 300 Amps continues requires 6awg to avoid thermal runaway ✌

Nice man🧲👍⚓️

[@ProspectorTripp]

Hello BBA, the power of that 200a controller is Crazy Power for sure! Before the wheelie crash, I just installed that blue 24v battery.. which I just modified for Maximum Current! Holy Smokes! The two 48v batteries in parallel with the Max Current 24v battery makes for a 72v battery with insane power. Stay safe BBA Peace Prospector Tripp

[@mrcoco3562]

I hear those controller can work without connect the hall sensors wire rights?

[@ProspectorTripp]

I don’t know about that point fully. I do have 3wire RC airplanes without hall wires but not sure about this point for bldc e-bike motors. Peace Prospector Tripp

I hope you didn't end up with any serious injuries from the fall 🙏

I would tell you if I was really injured.. I am doing excellent! Recovered in one day! 🤓 Next.. 😂 Thanks pal Peace Prospector Tripp

[@scottrocks1993]

Your copper wingdings look like they've already started burning out. It should be bright orange not a dark colour. When that happens starts to get more resistance. Get less power

[@ProspectorTripp]

Thanks for the info.. let er smoke if needed! 😂 Peace Prospector Tripp

[@robertmcfadyen9156]

The motor housing is too small and cannot dissipate the heat losses effectively . The unit would need to be larger in the same way that high current transformers are larger than low current (Amps) ones . My Yamaha FZR motorcycle is faster than your e - bike .

[@mackattack8627]

Oh man i love this reminder electric motors have 3 times the Torque than combustion engines at ZERO rpm,s im 56 now been building Pev,s for the last 20 years 10kw -40kw & still get dumped off certan bikes i build unless i add a 34" swingarm ✌ 😂😅

[@ProspectorTripp]

Safety 3rd 😆 Please stay safe sir Peace Prospector Tripp

[@scottrocks1993]

Even at 72v 50 amps Will hate that hub motor up . And copper coils will become oxidised Then well lose a lot of performance. I upgraded a 1000w 48v hub motor last month. (1) bigger wires (2) cooling ferro fluid (3) cooling radiators fins And it's still gets too hot for my liking. It's only using a controller 72v 50A. I can only imagine with double the amps and No cooling mods. It will definitely burn out

[@ProspectorTripp]

Understand.. gotta get the 80 amp controller installed to give it a chance. Thanks Peace Prospector Tripp

[@mackattack8627]

Awww man even the Dog knows its time to go back to the drawing board you definitely a Tuff Og stay under 100 amps with no whellie bar or extended swingarm electric motors have toooo much instant Torque without a redline 😅😂✌

[@48thstateprospecting]

Judas Priest😳😳😳 you should hook up your speed controller from your sluice to that thing, so you can dial it down a bit….😂😂 seriously though if you could give it half Power for starting out you’d have something there (until the front wheel bearing melts from doing Mach 10 with your hair on fire…) that gave me flashbacks to 1999 we drove to Phoenix to buy my 13 year old a dirt bike (a used Yamaha yz 250) I took it out on the highway behind my in-laws to give it a test spin ran down the road and back and turned it around and thought… ok let’s see what this thing can do shifted from first to second about 1/3 throttle hit third and punched it…. Had no idea it had a power band…. Up on one wheel I went and as the front wheel lifted off it automatically made me twist and increase the throttle.. just before I flipped over backward I twisted the throttle back down and pulled over to the side of the road and replayed the part where my life flashed in front of my eyes…. I drove it back to the house and the wife said what do you think I told her it’s to much power for him up in the mountains with trees…. He made it about 3 weeks before breaking his ankle… glad you ok and you caught it on film if condense that down and make it into a short you may get a million views out of it 🤩(leave in the safety gear bit for sure) thanks for sharing was a cool and informative build see you on the next one👍🏼👊🏼

[@ProspectorTripp]

Yes sir, those yz’s really cook. Glad you lived 48! Most of us have done a few things that have helped us understand how the physics of blacktop is, in fact very Hard material! 😂 The little mountain bike that “Could” is going to get its 80 amp controller. I got some additional documentation from Sabvoton so hopefully it works. I was definitely surprised buy the power. I just finished upgrading the 72v battery and wow.. the wheelie crash proves it worked! 😂 The huge wire motor modification with the high current battery all being pumped into the motor coils with that 200 amp controller really made this one too fast. The planned 80 amp controller is still a lot of power. Hope it works! Thanks for your terrific story! That’s Golden 48 Peace Prospector Tripp

[@48thstateprospecting]

@@ProspectorTripp so could you run the 80 amp for start out and switch to 200 amp once your cruising ?? Hehehe… or would you need a bomb squad suit for protection in case of a wreck…

@@48thstateprospecting no need.. the 72v 80 amp controller will be plenty of power for this very light build. The 200 amp controller is for another more far more safe 4 wheel diy ride. Thanks 48 Peace Prospector Tripp
