    Advice for powerwall

    Hi guys! I know this is maybe not the main subject of this forum, but there's a lot of knowledge here, so I thought I should give it a go. Long story short, I am building a powerwall, and scored a great deal on a 24kwh e-golf pack. I had limited time to do research, and after disassembling the...

    Hubmotor hydro generator

    I have this creek running through my property. It is only a 60cm (23") head, but it usually flows more than 3000lpm (790 gpm) throughout the year. I know it is not enough to generate a whole lot of power, and its definately not cost effective, but I want to build a water wheel. Mostly because it...

    Recommend me a controller

    Guys, I could need some recommendations for a controller. It is about a vehicle that is already converted, and it is almost doing what it should do.... Here's the short version: Old Polaris 6x6 converted with a QS 138 3kW mid motor. I have kept the original driveline and gearbox, so in the "Low"...

    Parts bin build.... kind of

    After having built a couple of ebikes that I use mostly for exercise, I think I have got a bit of the ebine bug.... First experience with ebikes was not very successful for my likings, but I have this battery that I assembled for that build laying around long enough that I figured I had to do...

    Whats wrong? Wheel build n00b

    Hi, guys. I had a MXUS xf40 30h motor with a 28" chinese wheel, and figured I would put it to use an try to learn how to build up a wheel on the way. So I ordered a 24" crystalyte rim and some spokes. I have attached the calculator screenshot and a picture of the wheel. I used 135mm 13/14 ga...

    Phaserunner settings

    Hi guys. I have a couple of ebikes running with base/phaserunner and small geared hub motors mounted as mid motors. They are running fine, but I basically had to guess at a couple of the parameters to get them to run as they should. One of the motors (Bafang G370) had a preinstalled config in...

    Polaris 6x6 diesel(!) conversion build log

    Hi all! Maybe not the typical project here on ES, but I thought I should share anyway. Basically everything I've learnt about electric conversions is from this forum, so maybe someone reads something interesting in this thread :) I already converted an 2wd basic ATV with a QS3000w motor and 20...

    CLD signal from torque sensor?

    I jave two bikes with a CYC torque sensor hooked to a cycle analyst. I think this is a remake of an erider unit with a different flange to make use of their freewheel. The wiring is kind of a PITA to redo, so Im being lazy and ask here first.... On the 73mm unit I guessed and hooked up the CLD...

    Charging a 12V lead battery from a 18s system

    Hi! I've been searching a bit, but havent found quite what I am looking for.... Is there a device out there that doesnt cost a fortune, and can safely charge a 12v lead acid battery from lets say a 18s system? I want to keep 12v battery on an ATV conversion because of a 12v winch that demands a...

    Faulty baserunner?

    Hi, guys. I recently received a new stand alone baserunner and a bafang g310 motor from Grin, and another small motor, Aikema 75sx. Both motors and the baserunner have the standard 9-pin connector. I have problems getting the motors to run sensored. When I run autotune, I get error "blue hall...

    How to calculate torque?

    I have one of these on the way (200 rpm version): http://www.topbikekit.com/144kg-akm75sx-36v250w-ebike-front-driving-hub-motor-203236-holes-p-905.html It will be paired with a baserunner and a 36V battery. I have found some different maximum torque values, from 32 to 40NM. How do I figure out...

    My attempt at a lightweight EMTB with torque based PAS

    So Im redoing this thread, too messy in last attempt.... Ive lately starting to get interested in single trail riding, and have 2 bikes equipped with tsdz2 motors. One fatbike for the easy rides, and one full suspension Liteville for going up the steep stuff, and trying to get back down without...

    Phaserunner on a Cyclone 3000W

    Anyone use this combo? I found a few threads about some problems with hall sensors, but no conclusion on those threads. Is anyone running this combo succesfully? Reason I want it is the "electric freewheel" setting. Im already using a CA v3 to tame the seriously jerky stock controller, which...

    My1018 brushless alternative?

    Im looking at making a diy torque sensor, low power (5-700w peak), light weight mid drive. I currently have a tsdz2 which I like very much, except the ground clearance. I do have a MY1018 brushed motor laying around here, a BB torque with a freewheel on the way, and a CA v3. Trying to make a...

    Charging with higher voltage charger

    Hi I have just finished a 16S6P pack that I would like to run through some testes before I wrap it completely up. The pack includes a bluetooth BMS where I can set pretty much most of the impotant parameters, and monitor each cell group. My 16S charger is of course stuck somewhere on its way...

    Adjusting voltage on charger

    Hi I have a YZPower 10A 20S charger Im using to charge a 20S battery made up from LEV40 cells. I want to cut charging at 4.1V per cell, so about 82V. I opened it up, and found 4 different pots. I found instructions somewhere on the web for which one I should adjust, but I can not get it lower...

    Main contactor?

    Hi, all! Im about to start an ATV conversion (QS138 motor, Votol 72150SP controller, 20 LEV40 cells, "bluetooth bms" from aliexpress are in the garage, ready for install) and I think I have got the most figured out. I've been lurking around this forum and learnt a ton the last few weeks, but I...
