    New TSDZ2B install issues: 2022 Rockhopper Sport L

    Hello all, I'm jumping into the mid drive world after loving my year with a front hub. It was amazing, until I got hit by a contractor van... Anyway, I'm running into issues with my frame fitting the motor. I was able to get the motor in by removing the cover to slide over the brake cable, but...

    Garbage heap S180

    So I've built 2 e-bikes before (about to do a 3rd), and am now working on my first scooter! It will probably be used around my work neighborhood for fun, since I don't have more room at home to store stuff. Conversely, it's small enough when folded to fit in a car trunk so maybe I use it for...

    15S Li-ion thoughts?

    There are obvious BMS and balancing hurdles, but what would people think about using a 15S setup for a controller with components rated up to 60V? My charger would top at 59V, so 3.9V per cell. My thought would be this would keep them in the healthy discharge curve for longer (stopping at 3.4V)...

    26x2 Tire advice

    Hey all, I've searched but the terms are too common to really find good results. I have a DIY commuter from an old steel 26 bike and an Amazon hub kit. I love it. I have gotten 3 flats from road hazards, and in my very infrastructure unfriendly area there isn't a good way to avoid encountering...

    Thoughts from a new convert

    I started down this path a few months ago because I had been harvesting lithium packs from recycling as I was building an 18650 power wall. I didn’t like not using these high current cells for such a plebeian task, and I learned how to fix many of the Ryobi 40V packs. I gave some away, sold...

    Cheap controller; will it 48V?

    So, here is my “JauoPay” Amazon controller. Allegedly 36V 750W, but the controller says 36/48V… Let’s look inside! Capacitors look good for a 52V pack (63V rated). 9 MOSFETs, Samwin SW062R08E8T. Can’t find a data sheet for these, seem pretty cheap though. What I see from Samwin looks like these...

    Battery mounting with Luna & Grin?

    Hey all, pretty new here but have been around DIY lithium batteries for awhile. Trying to figure out a good solution for a removable battery mount. I have a rectangular 10S5P pack that I would like to be able to take off to charge/swap with a fresh battery. I do still use my bottle cage, and...

    New member, first cheap commuter build

    Hey all, I’ve been into the 18650 second life power wall scene for a year or so and ended up with a ton of tool cell batteries. I figured out how to fix many of them, especially the Ryobi 40V packs. During this time I also rebuilt some Headway packs to power my golf cart and got comfortable with...
