Just a heads up, this mod caused cutouts on this model and we didn't get more speed. Had to use a higher voltage battery and higher quality controller to get more torque and speed, as seen here kzbin.info/www/bejne/m2a1YoKbfJx5ec0

I did the shunt mod on my 1000w speed controller and I modded it too much. According to my BMS it was drawing up to 4000w and the motor would do this funny thing where it felt like it was almost dragging a brake when punching it full while going slow. I actually had to reverse the mod and put it back to stock.

Just want to help others from frying their controller if they try this mod... the wire used to decrease the shunt resistance needs to be MUCH smaller than what was used in this video. The wire will need to be 22-24awg, or smaller, depending on its length. A recent controller I modified used an SMD shunt resistor (similar to this video) of 2 mohms (that's 0.002 ohms). A 22awg piece of copper wire that was 1.5" long had an equivalent resistance, so adding that across the SMD gives an effective resistance of 1 mohm. Torque was dramatically increased and the controller gets warmer than it did prior, but not hot. Voltage drop, while accelerating, has increased as a result, which is my guess as to why the OP was experiencing cutouts after their mod (BMS shutting down due to too high current demand).

i did this mod, i went from 60amp to 97amps. it lasted maybe 20 miles. it actually died on me going super slow up a slight hill. i was going intentionally slow about 6mph, to watch the amp load from two different meters. at the time it stopped working i was using 10-30 amps average about 15 amps. it was a dirt trail that was a tad muddy, but i was not spinning the tire. all of a sudden it went limp. no popping sound, no smoke, but then again it appears to be sealed. that was a long walk out of those trails/hills all the way back to pavement with what felt like an engaged brake. i had to drag that thing home another 3 miles once i got back to pavement.once i got home i unplugged the motor and it began to spin freely...uhg i opened the controller up and found two destroyed mosfets. i ordered the replacements and just before i installed them i inspected the controller board very carefully and found many things were destroyed. almost looks like random traces underneath some layers of the pcb were fried and brown looking. if i do this again, i will be very careful to only put a tiny amount, these two weeks waiting on my TWO new controllers this time of year sucks as i know the days are very limited at this point this time of year

Would the thinner bit of wire let less amps or less currant through will only do a little bit more top speed/acceleration, as a thicker bit of wire will allow more amps or current to flow through giving more power to motor for more top speed/acceleration am I right in thinking that or am I wrong?????🤔🤔🤔👍👍👍👌👌👌👌👊👊👊
