CITYCOCO, MOTOTEC, TOXOZERS SPEED CONTROLLER SHUNT MOD

[@TechKnowCSS]

AFTER TESTING... I DO NOT RECOMMEND DOING IT THAT WAY... BUT IT DOSE GET UP TO 40 MPH /65 KPH ALMOST INSTANTLY AND POSSIBLY FASTER BUT I DID NOT HAVE THE GUTS TO LET IT GET ANY FASTER. (PROBLEMS) (1) HIT IT HARD FROM A STOP AND AFTER 50 FEET THE SELF RESET-ABLE FUSE TO THE CONTROLLER POPS AND SHUTS EVERYTHING OFF. (2) BATTERIES GET HOT FAST AND DRAIN LIKE CRAZY. (3) DYNAMIC BRAKES DRAIN THROUGH THE SHUNTS SO IT SLAMS THE DYNAMIC BRAKES ON HARD, NO LONGER SMOOTH JUST BY ONLY TRIPPING THE BRAKE LIGHT. (4) DECELERATING THE THROTTLE ALSO HITS THE DYNAMIC BRAKES HARD AS WELL. HOWEVER I HAVE A CURE, I WILL RUN THE JUMPER THROUGH A 40 AMP CAR RELAY TRIGGERED BY A BUTTON ON THE LEFT HANDLE WHERE THERE IS A BLANK PLACE TO MOUNT IT AS JUST A BOOST BUTTON. ONLY HAVE TO HAVE ONE WIRE COME OUT THE CONTROLLER WHERE THE SHUNTS GO TO AND THE OTHER WIRE RIGHT TO THE NEGATIVE SCREW ON THE CONTROLLER THAT WILL GO TO THE RELAY TO JUMP TOGETHER FOR INSANE BOOST, LIKE A SCRAMBLE BUTTON.

i have a CP4 same model however advertised as a 3000w motor do you suggest me to do this upgrade (controller box ) ? i would have a dual battery setup in the coming weeks . will replacing the throttle switch make much difference? have you tried the 40amps relay mod yet ? any improvements ? is there any way to wire it upto use the bridge only when you are using the full throttle or when selecting speed 3 ?

[@TechKnowCSS]

I DO NOT RECOMMEND THE DIRECT JUMPER BUT YES THE 40A RELAY ENERGIZED BY A N/O PUSH BUTTON ON THE HANDLE BARS NEXT TO THE GRIP BECAUSE I DID THE RELAY MOD AND IT GIVES 15-20% MORE TORQUE FOR FASTER TAKE OFFS AND QUICKER TO TOP SPEED BUT REALLY DOSE NOT INCREASE TOP SPEED, I RECOMMEND NOT HOLDING THE BUTTON LONGER THAN 20 SECONDS TO BE SAFE ESPECIALLY UP A STEEP GRADE. WITH THE RELAY MOD THE WIRES THEMSELVES DO SILL HAVE SOME RESISTANCE WHICH IS A GOOD THING, AS FOR THE THROTTLE REPLACEMENT I ONLY RECOMMEND IT IF YOU TEST YOURS AND THE MAX OUTPUT VOLTAGE IS LESS THAN 4.3 VOLTS BUT CAN BE AS HIGH AS 5 VOLTS. MINE WAS 4.1 VOLTS AND AFTER REPLACING ONLY INCREASED SPEED BY 2 MPH NOT KPH BUT I THINK IT WAS WORTH IT. I SOLDERED ONE 12G STRANDED WIRE TO THE CONTROLLERS SIDE OF THE SHUNT RESISTORS AND OUT A HOLE I DRILLED OUT OF THE BOX ABOUT ONE FOOT BEFORE THE RELAY THEN ONE MORE FOOT AFTER THE RELAY TO THE NEGATIVE POWER SCREW OF THE CONTROLLER.

i have a new city coco m3/chopper. the lighting system does not work. Can you tell me where to look for the fuse or how to fix that? I am wondering if it shorted when it was first connected. HELP. I am NOT an electrician by any means. I do not have a diagram like yours. I have notified the store seller for warranty service. In the meantime, if it is a simple fix, I am all ears. My Bike gets power to the speedometer, and will go into gear to ride. Just no lights.

Well done very good . I will watch more.

[@123123marki]

Hey i have a CP-4 and i'm trying to do the mod now. Do i wire the cable on all 3 shunts? Because, you're shunts are on the middle/right section. But mine are left/middle sections wired. Will it make a difference?

[@MrTimmmers]

Try this. Insert key, full throttle and gold brake at same time, turn on with key, wait 10 seconds, turn off with key. Restart should unlock it to about 60mph.

[@mrdayvidjon]

Wonderful reserch your doin for e-chopper community thank you so much I soldered my shunts together instead point to point like the way you discribed should I undo that and do your recommendation?

[@TechKnowCSS]

I USED A 40A CAR RELAY WITH A MOMENTARY BUTTON TO "ENGAGE" THE SHUNT TO USE AS A SLIGHT BOOST OF TORQUE, IT DID NOT HELP IN TOP SPEED, THE RELAY WAS BECAUSE THE DIRECT SHUT WAY WAS WAY TO ABRUPT ON THE DYNAMIC/RE GEN BRAKING.

[@attilapap6285]

Does the description on the paper match your controller? At two points, for example, the ground is not there, as it is on the panel. I have a different type of controller on my bike. It failed because the top speed suddenly became 25. Everything I do is 25 speed. I bought one of this type, but it has a different connection, so it has to be rewired. It's good that I found this video, but as I mentioned, there are 1-2 problems.

[@TechKnowCSS]

THERE ARE SO MANY THAT LOOK ALIKE BUT NO THE PAPER ON THIS ONE DOSE NOT MATCH, HOWEVER I MADE ONE MYSELF THAT DOSE MATCH THE PINOUTS.

[@attilapap6285]

@@TechKnowCSS The paper matches my controller in it. Is there a wiring diagram for the SS12-60V-YTC-25? The symbols on the panel do not match. HALL sensor, GND and VCC ok. Throttle lever, brake switch, gear shifter and the TXD connection would be required. Thanx

[@Ponnybit]

thank you for your video sir, i hope you're doing well all the best!!! i'll try this soon :) Im also thinking about making a trigger near the throttle, i'll pass the shunt mod through a high amp relay, then drive the relay of 5v from the throttle.. did you ended up doing this? i read in your comments bellow that you had some issues driving and you're putting some sort of switch. i would only use the mod going on a flat straight road or while going up for a tiny boost!!! greetings from portugal, Best

[@toughguy2186]

I am just curious, what country you guys live in, (not trying to be funny or rude) City-cocos are the same prices EAhora and EAhora M1Ppro does 49 MPH out of a box without any modification to speed control, cost pretty much same as city-Coco

[@aliecat321]

Any idea why my lowboy won't start at all? I replace the motor that you're working on the ignition switch and the battery still will not start

[@TechKnowCSS]

Check your brake switches and kick stand switch and wires that they both will disable the bike.

I have the same controller an search a way to "unlock" the speed. On my There are only 5 wires in the big plug pin 2, 12,13,14 and 16. I don't finde any way to drive faster than 45kmh. Is it possible so attache a citycoco m1 controller on it ?.

[@TechKnowCSS]

ANY CONTROLLER CAN GO ON ANY MOTOR, JUST HAVE TO KNOW THE WIRES ON THE CONTROLLER AND TRACE OUT THE ONES ON THE BIKE. ALL YOU NEED IS THE 3 BIG PHASE WIRES, HALL WIRES, THROTTLE WIRES AND POWER FOR ANY OF THEM TO WORK. (THERE MAY BE A "ON" POWER WIRE).

[@klyddmeisters]

This mod need another battery. Those batteries are not made for high current. It is much better to go for another controller that is programmable and build a now battery with higher voltage. 20s is way faster than 16s and you dont need more amps. 84v and 35 amp gives you 3000 watts and it should have a max speed of about 45-50 mph A 20s8p with 21700 cells will give you about 84v 40Ah and a range up to 80 miles

Dear Sir; I hope you are doing well. I know very well that you’re a high-level expert on BLDC controllers. I live in Turkey and I freshly bought a New 2020 Shansu (citycoco) CP-4 3000w 12*7.5 inch fat tire BLDC Chopper from reseller. I am in the edge of upgrading my controller and I don’t like to waste any money, but find the most accurate and compatible controller for my bike. Unfortunately no one here seems to know anything about BLDC controllers especially related to these kind of motorbikes. Therefore your consultation is very appreciated. My system is 60V&35A by default however installed an extended battery pack and with default controller, now it’s running on 17S7P (3C) 64V & 35A battery setup. By the way the original wiring is terrible. Therefore I upgraded the wire between battery and controller to 10AWG while upgrading the power slots to XT-90. By default, I can reach 700-722 RPM with no problems under many conditions, that means 65-70km/h. However, more torque & max speed is a must, when it comes to dealing with hills and highways of my city. From your youtube broadcasts and comments, 72V 80A is the final sweet spot for our rides. Therefore I’d like to have your valuable experiences, thoughts and suggestions on my following issues below: 900-1000 RPM will be the best option for me under several conditions. Cranking up the voltage to 72v seems to be the cure for this issue. However there are terminology like “flux weakening” while talking about speed of BLDC motors. I am planning to buy VOTOL EM-70S controller for more output. It has “flux weakening” and the programming interface seems to be more user-friendly than most of the others on the market. Its negative aspect is supporting only 60A nominal whereas 80A could have been better for us. If you suggest a different controller, which controller should I use in terms of i. Programmability and customizability, maybe having “self-learn” advantage ii. presence of “flux-weakening” option for extra speed, iii. durability of MOSFETs and overall setup iv. conformity to the BLDC motor of our bikes v. applicability with our default double cylinder shaped speedometer display I I’d like to thank you in advance for your valuable answers and guidance.

[@TechKnowCSS]

I had long ago upgraded to a 72v 80a PURE SINE WAVE controller as a clone of the SABVOTON ML7280/MZ7280 PURE SINE WAVE controller for my 2500W 60v hub motor, Yes 72v for a 60v motor. Motors are not voltage bound, they are watts so i am now getting over 4000W. The original 2500W motor can run 24/7 at 2500W but can put out over 10KW for 10/15 seconds and 5KW for a minute or so WITHOUT damage. VOLTAGE= speed.
