    Review my latest battery build? Molicel p42a 10s4p 21700

    Just as an update, I’ve put many miles on the battery, and all I can say is WOW. These cells are nuts- the added capacity is incredible. If anyone is having trouble choosing between 18650 vs 21700, it’s a no brainer IMO. I’ll only be building 21700 from now on. These cells are great.

    Would a Dawes Karakum be a reasonable donor bike for use when using an e bike conversion kit.

    From what I can tell that frame doesn’t have mounts for disk brakes. That’s something I always look out for in a donor frame. Not sure how powerful a motor you’re going with, but something to consider. I converted a Dawes Discovery with a YOSE 350W kit and was very pleased with the results. I...

    Review my latest battery build? Molicel p42a 10s4p 21700

    Thanks for the feedback everyone! It wasn’t a complete failure, the battery would clip when under heavier load (250W bike). It was my first battery build so there were a lot of points of failure. I tried my best to dissect it to diagnose. I found two of my welds on cell group 9 failed. Didn’t...

    Review my latest battery build? Molicel p42a 10s4p 21700

    Hey Folks, The first battery I build finally failed, so I got to make a new one! Decided to go with 21700 cells this time. Last time I posted my battery I got a lot of great feedback on mistakes I could improve. So if you feel like giving me some feedback on this build, would be very happy to...

    Dawes Discovery 201 + YOSE 350w 700c Kit + Samsung 25R 10s4p

    Bike is all built! we took it for a ride across London Yesterday and it was lovely. 30km ride and battery still had some life in it. Very happy with this kit, my partner said she felt she always had power available when she needed it. Likely too fast for her, but she can finally keep up with...

    Yose Power kits in the UK

    I just got mine on Amazon, but the price was considerably higher (240gbp vs 190eur) shipping was quick and painless.

    Dawes Discovery 201 + YOSE 350w 700c Kit + Samsung 25R 10s4p

    Thanks for asking. The controller is rated at 9a cont., 18 peak. Nickel strips are 8mm x 0.15mm. I installed a 20A fuse. I had a look at this chart at by the looks of it. Even a single nickel strip would be sufficient for the continuous current, no?

    Dawes Discovery 201 + YOSE 350w 700c Kit + Samsung 25R 10s4p

    New battery built. Ended up going with Molicel p26a since Samsung 25R was sold out everywhere, Took the bike for a spin and it was great. Hit close to 40 km/h with the throttle only. It’s nice that the controller lets you easily set a max speed. I think I’ll keep it to 30 since my partner isn’t...

    Dawes Discovery 201 + YOSE 350w 700c Kit + Samsung 25R 10s4p

    Hi Folks, First off, thanks to everyone who provided feedback! Build is going pretty well so far. Rear wheel went on like a charm. Disk brake as well. If I'm lucky I'll be able to wrap up the electronics and brake cables this weekend.

    Dawes Discovery 201 + YOSE 350w 700c Kit + Samsung 25R 10s4p

    Thanks! I’ve ordered the kit. I also ordered some magnetic brake sensors (seemed they will do the trick). For the disk brake, I’ll go with a mechanical disk caliper. I’m pretty sure it will fit on the frame (photo attached). I’ll sort this part out after the kit arrives.

    Dawes Discovery 201 + YOSE 350w 700c Kit + Samsung 25R 10s4p

    Hi Folks, I'm working on a conversion for my partner. She wanted a very light bike that could maintain speed so we could bike together (she has a smaller pedelec now with 20" wheels) I'm going to be working off of a Dawes Discovery 201 donor I've picked up for 90GBP. From what I can tell, an...

    Building Charger for Sanyo Eneloop (CY-EB60 / CY-PAA6)

    Just a short update here. I've tried supplying that 3'rd control connector anywhere from 2.8->28v. No difference in terms of response from the Bike. Seems the electronics are complex enough that you can't really operate this bike without at least an original BMS. I'm going to try to source a...

    Building Charger for Sanyo Eneloop (CY-EB60 / CY-PAA6)

    Hi There, had some time to spend on this during the Christmas break. I've come to the conclusion there is something wrong with the current BMS. While the battery has ample charge (26v), the output of the +/- of the is never 26V, and the LED light indicators show no sign of life. I decided to...

    Building Charger for Sanyo Eneloop (CY-EB60 / CY-PAA6)

    Thanks for the input. The charger is the only device with the S and T ports, so I may have to import one from Japan to figure this out. The bike only has + , Y, - (photo below). I'll open up the bike this weekend to see if I can get any clues. I'm beginning to fear the issues with the battery...

    Building Charger for Sanyo Eneloop (CY-EB60 / CY-PAA6)

    This morning the battery remained at 25.4V, so at least it's holding a charge overnight. I reconnected the BMS, but unfortunately that didn't go well. It has a button with 4 lights which "should" show the charge level, but the button doesn't seem to be doing anything. Furthermore, when I...

    Building Charger for Sanyo Eneloop (CY-EB60 / CY-PAA6)

    Hi Folks, Short update here, parts came in and I've given it a charge. I decided to remove the BMS in the off chance everything went terribly wrong and it fried. I've charged the cells at 29.4V 2A for 1hr. Very happy to see consistent voltage across the parallel groups throughout the charge...
