The Makerhawk load testers are made by Atorch and sell for a bit less on aliexpress. If you have the version with the dial for setting current, don't change the value when it's on load.Adjust when the load is off. Mine glitched and blew up, I replaced with the model with color display and that's...

You should have referenced your other thread, Mike. There wasn't enough info in this stand alone post. https://endless-sphere.com/sphere/threads/52-volt-battery-issue-14s9p.124126/#post-1809176 Still don't have enough info. What was the pack voltage when the scooter shut off? It should have...

I believe that tariffs on small individual orders on aliexpress fall into some crack and are ignored.. Back when the Cheeto started these trade wars, and ebikes were going to be included, I bought my TSDZ2 kit from pswpower a month before it went into effect. Didn't even open it for a couple...

You may have already read thru this thread. Someone looked inside his controller box and only saw two wires on that connector going to the battery. Yours is different? https://www.pedelecs.co.uk/forum/threads/swytch-kit-compatibility-with-non-swytch-components.44851/

The batteries that I have seen with integrated motor controllers put them into the battery cradle. And when I look up Yost, that' what they sell...

Our normal pace is 12 mph. Been doing that for 9 years on shared trips. She couldn't ride her torque sensor bike that fast because it took too much pedal pressure to activate the motor, even when she was in turbo mode. Fortunately, the motor has a cadence sensor too, and there was software...

Grin's gear is nice, but busts my budget. A simple geared motor with cadence sensor, KT Controller/display and a battery is less than a grand for me. Probably millions of people slogging to work every day on something similar. I don't have to ride to work, but if I did, I wouldn't want to work...

I would expect that your charger works on the other battery and there's something wrong with the first one, You'll want to replace it. Here's my guess on what's happening. Ebike batteries disconnect the internal cells from the power pins if any of the cells are too low in voltage. When this...

Can you move the battery from one bike to another. Could the first battery be too high or too low on voltage?

I agree with E-HP, the LCD3 and an 18-20A KT controller will run most 26" bikes around 13 mph in PAS 1 at 36V. Probably will show about 120W on the LCD display. If you wish to go slower, the current can be reduced by up to 50%. with an LCD3 setting (C5). and there is also a setting (C14) for...

The difference in indicated speed could be due to LCD settings for the magnet/gearing or differences in pulses/rpm from any discrete speed sensor in the motors. I don't see how the PAS is affected by the motor, if the PAS sensor is on the pedal axles. If it were on the motor axle as is done...

Some batteries only use two of the 4 pins, Some pair them up with positive on two and negative on the other two, . Occasionally, vendors will reverse the plug polarities. You have to check with a voltmeter tobe sure it matches the ebike, if that's your application. The same cautions apply to how...

I found this picture of a Genze 101 battery, Five modules, with each module holding six cells. I expect each module is arranged with two groups, each group holding three cells in parallel, That would give you ten groups in series, 3 cells in each group arranged in parallel, commonly called a...

I purchased the Battery Hookup Molicell M42's last month. Tested one at 4.2Ah on my Littokala tester with a 500ma load. Made a 13S-1P brick to see how they worked. Makes for a nice compact battery. My load tester says it's 3.8AH with a 3A load. I was disappointed with that, hoping it would do...

I know the protocol for a right turn using the left arm, but I prefer to point with my right arm for right turn, and left arm for left turn. I don't expect anyone in the USA to recognize the left arm signals.
