    Fourstar Trike Resurrection

    Final assembly complete. Doing some shakedown testing over the next week or so before heading to a golf course.

    Fourstar Trike Resurrection

    It has a top speed of about 15kph and yes if you crank the bars at that speed you’ve become a 2 wheeler and it will take a some skills to keep it upright. For me it’s a golf cart and I’ve no intention of testing it’s limits in the corners :)

    Fourstar Trike Resurrection

    Got a bit side tracked over the winter but did get the frame sent out for powder coating. Have also cleaned up all the plastics, repaired cracks and various misc PO holes from it’s “gas” days and everything is painted Audi Nardo Grey. Paint is curing while I complete assembly. Have also...

    Golf Cart Motor - Lawn Tractor Conversion

    I'm converting a tired John Deere 100 series lawn tractor to electric and will be using a 36V Club Car motor with Curtis controller that all bench tests fine. The challenge with these golf cart motors is they don't have a front bearing plate since they use the differential connection/housing to...

    Fourstar Trike Resurrection

    36V (10S10P) battery built (stock voltage) and bench tested controller, motor and all the other ancillary bits. Still waiting on contractor and discretes for the pre-charge circuit. Still have to mock up on the frame, open the motor’s gearbox to inspect and lubricate and clean up the frame from...

    Fourstar Trike Resurrection

    And your stapler reminds me of a jet ski … perhaps I should just put pontoons on this beast :)

    Fourstar Trike Resurrection

    Got my hands on one of these that the PO removed all the electrical drive components and mounted a gas engine. It’s seen some better days but for the 100 bucks I paid with a miscellaneous box of old parts including the original geared motor I thought it would be a good project. Of course the...

    Golf E-Caddy

    Just completed a third season of 50+ rounds and my caddy held up perfectly. Did some functional and cosmetic upgrades over the winter and here is how it’s all kitted out. Another long Canadian winter ahead so perhaps more tweaks to come for the 2024 season :)

    Urban Kick Around Build

    Finished! Added a temperature monitor and cut off to the enclosure and tested with a 15k run of hills and cruising with no issue. Bike seems to be performing as expected with the original design parameters. I struggled lacing the wheel and could never get it properly aligned in a 2 or 1 cross...

    Golf E-Caddy

    Well the end of another Canadian golf season and my e-caddy took me through 50+ rounds this summer! It was 99% problem free with the only unfortunate event being a flat tire very early in a round that I could easily get back to the club house, grab a cart and finish my round. $5 later I had a...

    Urban Kick Around Build

    Completed the wheel lacing and endless efforts as a rookie to true-it-up. I got it pretty close so fitted everything on the frame and took it for it's first road test. All seems to be working as expected but will have to play with the S866 display to configure all the parameters. The...

    F150 Conversion

    FWIW, exchanging information only in private about a project posted in public seems strange; it doesn't do very much to share that information or preserve it for the future. :/ Amberwolf - I’m simply trying to respect the Board as I have no interest in promoting my company, our partners or any...

    F150 Conversion

    I manage about 150 vehicles as the core of our fleet that services the hydro and water needs of our city. These vehicles are 100% maintained by our talented crew of technicians and they work on everything from our UTV’s through to large double bucket trucks. Electrification of certain platforms...

    Urban Kick Around Build

    Battery and box is finished. Decided to move the controller onto the seat post as space was just a little too tight for comfort and there was plenty of caution offered from the forum on heat in the enclosed space. Bench testing all the parts proved out so now just waiting for the spokes and I...

    Urban Kick Around Build

    Good point and it has me a little concerned as well. I’m planning on keeping the side cover off and road testing how much heat will be generated inside the box under different conditions before I finalize everything. Based on the intended rider I suspect it’s not a problem but need to design for...

    Urban Kick Around Build

    Making progress - battery/controller enclosure designed and printed (yes she wanted a rocket on the side). Going to be tight once all the wiring comes in to terminate so hoping I don't have to push the controller to a separate enclosure. This is as big as the bike triangle can accommodate -...

    Urban Kick Around Build

    A friend asked me to add power assist to her 21 speed bike she kicks around the neighbourhood and some mild trails with the family. Am going with a 350W 36V Bafang rear hub with 22A controller, S866 display and 10ah pack build. Not much to share yet but the parts are on order and I’m building...

    Power Tool/Mower Batteries For Off Road Go Kart?

    I used EGO 56V battery packs on my ATV conversion and they work. I don‘t know any details but they have internal BMSs that protect the individual integrity of the pack and not sure how they are supposed to interact in parallel when used in their intended “tool”. I did parallel 2 EGO packs on my...

    Electric ride on lawnmower

    Think if it were me I would still want an E-Stop on the blades then a simple toggle switch to turn them on/off. The switch would cut in/out a voltage divider circuit that acts as your throttle that when off is at the low throttle voltage for your controller (0-1V) and when on it’s at the high...

    Fardriver 72360

    Just starting down the path of swapping out my controller to this unit. Haven’t done the deep dive of looking for someone who has already done the hard work of unraveling the communications and programming parameters so if anyone has already been down this path and can make a recommendation for...

    ATV conversion

    Here’s the kit I installed from OMB Warehouse. Am sure you can get them from all sorts of sources local to you …

    ATV conversion

    I built a 14s5p battery with Sony VCT4s (10A continuous) and tried to see if it was current that was limiting the performance and it had no affect to torque over the EGO batteries originally designed in the build. I am swapping out controllers to a FarDriver now but suspect ultimately these...

    ATV conversion

    I did a very similar conversion last year and had the same experience. 2000w with 35A controller https://endless-sphere.com/forums/viewtopic.php?f=34&t=109518 You have to look at the gearing of your set up. I ended up putting a huge rear sprocket and jackshaft in between to get the torque to...

    Looking for advice setting up battery using high current cells

    Probably a good question to research and post in the Battery Technology forum.

    Balancing question

    The BMS drawing from banks 1&2 makes perfect sense now that you’ve pointed it out. I’ll do a little research to confirm. Thx!
