Hey Pat! Loving the series. Just got an mx650 to mod myself. Your videos have helped a lot in determining which direction I want to go. Do you think the lower BMS is because that pack uses LifePO4? I have been eyeing batteries from BTR Power but I have always heard it’s best to get lithium ion as opposed to lifepo4 (which I know is still lithium but seems it’s usually meant for deep storage as opposed to ion for power sports) Also if you haven’t ordered a 72v battery yet I have a couple links to suppliers using LG or Samsung Cells and they let you select what BMS Amp you want. I priced out a 72v 40AH with 60A BMS Samsung Cell and it was $850 a 72v 31AH LG with 70A BMS was $700. Can’t wait to see more videos ! Your tire video was one of the most helpful for me by far. Subscribed!
Thank you sir! Regarding LifePO4 vs Lithium, there are a lot of opinions on which is better and why. BTR offers both, but honestly I chose this specific battery simply due to BMS Amp output rating (for the price), which is why I was a bit disappointed. They've been very helpful and refunded me for the battery anyway so really no loss here. Hopefully I have better luck with their 72V battery. Shoot me some links to the battery options anyway since I am building another bike soon and may go that route if I can't fix this battery later on. Hope you didn't go too big on the rear tire like I did! I'm probably gonna stay with 3.0x10" rear next time around. I noticed my 3.5x10" rear tire still rubs a bit when my tire expands going 40+ downhill.
@@PatOutdoors I went with a 80/90-10 Rear tire. The 3.5x10 sits 16.5” tall which is causing your rub. The 3.0x10 sits 16.5” tall as well which would cause same rubbing issues. The 80/90-10 is 15.5” tall so it fit stock setup with no need to move the motor back like you did and it’s just slightly less wide than the 3.0x10. A 2.75x10 would fit stock as well as its height is about the same as 80/90-10 but it’s not as wide as 80/90-10. That’s awesome to hear they have great customer support like that! Note that these batteries yes will be a little wait on shipping but I have done a lot of research and these should fit in the stock mx650/mx500/sx500 bottom tray as they have sides less than 203mmx155mm which is the bottom tray length and width. 30ah Samsung 60A3500w BMS - a.aliexpress.com/_mLCNoAk 31ah LG 70A4000w BMS - a.aliexpress.com/_mPNLtC8 30ah Samsung 50A3000w BMS - m.dhgate.com/product/72v-30ah-electric-bike-lithium-battery-downtube/513024175.html 40ah Samsung 50A3000w BMS - m.dhgate.com/product/3000w-72v-40ah-lithium-battery-pack-72volt/512439429.html
Hey @Pat Outdoors i just bought a 48v/72v 2000w controller to replace my burnt vevor one and im trying to get the ignition to work, I have a yellow and white wire for the ignition connector. I think one them goes for the red o ring door lock, but i dont know the power source for throttle.
Hi so I’m not fully speed hungry but I am very much acceleration hungry. I have an 1800w vevor motor. If i upgrade from the 33amp stock controller to this 45amp controller, will I see a lot more acceleration? Or is it relatively the same. How much would you say it affects the torque and feel? thanks in advance
Yeah, I'm likely going with a pre-programmed Kelly by Lonestar on one of my next bikes. I know it pulls a ton more amperage / current than any of these cheaper controllers.
Awesome video! I have the same controller with a 48v battery. Question, where did you run the yellow and white cables for the ignition/keylock? By that I mean what do those two connect to on the controller? Thank you so much in advance!!
I have the same throttle trying to hook it up on a stock mx500 controller.. i have the same problem.. i dont know where to connect the white and yellow wires..
So for the kit I’m looking at on Amazon it’s a 2000w kit motor with control and everything and it says use a 48v 30amp hour battery but could I use a 48v 20amp battery?
Heyy question which 72v battery did you order? And i have a lithium ion 52v one that also said it has a 50amp bms you think i should open and see if its lower to get a refound?
What's the reason for this? I was having a shorter-than-expected battery life issue, which is the only reason why I opened it up. They have a really good warranty so I wouldn't recommend doing that unless you're prepared to void it. Is it over a year old and what is your controller rated for? I ordered the 72V 20AH with 50Amp BMS.
Well no actually is a new battery bc I’ve been following your build so when you bought your I bought mine the only thing is that i ordered a 52v instead pf the 48v But the thing is that i wanna upgrade now to a kelly controller and I specially chose this battery because it has a “50 amp” bms so i wanna make sure it really does so it can handle the kelly controller without any problems
Hi, you have 48V motor and 72V battery can you please explain it? I am still thinking what to buy, they'r not making 72V 2000W, only 48V and 60V. Also do you think 60V battery would work with that controller? Thanks!
Hi I’m wiring it right now and I can’t figure out which controller wire shows the volts on the display. My volt display on my throttle has one yellow wire. What wire on the controller do I connect that yellow wire to?
The yellow wire goes to B+. You can either run it directly to battery + terminal or use a multimeter to find with wire on the controller outputs the full battery voltage and connect it to that.
@@schmeglyomigy6174 the b+ wire from the controller is a ring terminal. You can simply strip enough of the wire, twist it into a ring and fastener it together with B+.
Hello I have a fast scooter kit 48volt controller kit and I’m looking to upgrade my stock motor to a brushless 1000w without a new controller is it possible it will work or will I need a new controller?
I have this controller but it does two things that I am not a big fan of. I was wondering if you knew any fixes for them. I have an 1800w motor, however, my top speed is only 28 mph with a 13tooth sprocket. I should be getting around 32-35, do you know why I am not? Also the other thing is that when I get down to around 60-70% battery or less, the low voltage cutoff on the controller cuts the power to the bike everytime you accelerate fast. Do you know a fix for this?
I’m using a 52 volt battery and a larger diameter rear tire, hence why I have a higher top speed. What’s the voltage reading when it cuts off power? Most 48 volt controllers cut power around 41-42 volts
@@PatOutdoors Oh ok I see. And yea for the lvc it is cutting it off at 42v. The problem is that the battery isn’t at 42 volts when it is cutting off but it reads 42 volts because it is under load. Do you know a way to bypass/change this?
Have you tested the battery voltage and test for blown fuses? If it's the unit that's bad, please contact the seller. Their phone number us on the controller
I have a question. I bought a battery 72v 30a. My controller says 60a. It's does shuts off when I'm riding at full throttle. Do you think this is because battery needs a 30a controller? I didn't realize this till I now bought it lol. $450 battery and didn't check the amps. I am a beginner btw
@@FishSquirrel is your battery’s BMS rating only for 30 amps continuous? That seems oddly low for 72v. You sure it’s not a 30AH battery with a 60a BMs maybe? What kind of controller do you have? Maybe you can turn down the power a bit to keep it from triggering the BMS
I recently bought one of these motors for my bike but I burnt out the vevor controller, I replaced the controller, but I'm having issues with the wiring. The wiring looks the same as yours but I still can't get. Could you help me i would greatly appreciate it.
@Pat Outdoors I couldn't find the vevor controller on Amazon, so I ordered another one. Similar to the one in your video. I can't seem to find the electric lock the wires don't match in color.
Not really, just a bit better than an on/off switch. What made the biggest difference on this bike as far a smooth throttle is when I switched over to a Kelly KVD controller in my later videos.
@@PatOutdoors I saw your Kelly controller diagram. Had problems with one i ordered and it kept throwing overvolt faults but beeping like it's a halls fault. Gave up. Never again.
Lol real talk. I had issues with that first BTR 48v pack. But then they warrantied it and offered me a 72v for a small price difference and it’s been holding up since.. though I have moved on the Amorge batteries with higher rated BMS
Good way to check if everything works before putting it fully back together and putting load on the system just to find out you gotta take it all back apart again to find out what's wrong.
