I did the mod to my 35 amp controller. It took a few attempts but eventually worked. I have a 2kw rear hub motor with 52 volt battery. The mod has probably doubled my torque. It's amazing. I can go up hills at 25 mph now compared to 15 mph before the mod. I say it took a few attempts. The first time I pulled the 2 shunts together and put a line of solder between them. That didn't do anything when I tested it. Then I put a coil of copper wire around the shunts and soldered it. That didn't work. Then I added a lot more solder and kept the soldering iron on the join for a long time to heat everything up, and that worked! That made all the difference. I immediately knew there was a difference in torque when I tested it. I think the success is due to heating the shunts up and then soldering them rather than just soldering them cold. I have no idea how it all works but would be interested to find out. I'm tempted to add even more solder to the join to decrease the resistance even further and make the bike go faster. But I'm worried about blowing something in the battery, or the motor.
Haw do u deal with the extra heat I did this and the controller was getting. So hot it was unreal melting all the hot glue on the aluminium case so put back to factory
the motor cannot be tuned to voltage, the motor with the thickness of the windings is configured to withstand a certain current strength, and any voltage can be applied, only the maximum speed will depend on this

Try adding strips of copper wire in the same direction as the shunts. Then solder hot!

What else has been done to your jetson to reach top speed ? Do you have link for controller ?
How is this mod holding up? Thinking of doing this with my ebike
Is that a Jetson Bolt Pro controller?
Do you have a link to where I can purchase them ? I cant find them anywhere.
So what was the difference in battery usage? And did you notice any significant difference i n motor temp?
1.3 what? what was your top sped prior the mod?
What else do you have under the hood on that help me out 😮
How u have ur settings?
r u running stock hub motor?
Are you running 36v or 48v?
for 1:34 do can you undo it/ do you leave the clips on?
Battery size...?...Controller Voltage and Amp numbers...?...It's not a stock controller...?
I did the same thing to my first bolt pro, but it fried my motor, the Jetson bolt pro motor is factory set for 36 volt only.

Flux makes a solder stick
PINKIE WE HAVE TO RACE I GET SAME TOP
I want to race 😂😂😂I got the haze buy everything is the same as bolt
“13% increase” “17% increase” lol…
Solder that scnitt!!
Less talk more to the point pls !
