Hi @Chalo, thanks for the reply. My daughter is 17 next month, (gaaa my little girl is getting big!), so I want to keep the speed to a reasonable number. When I was that age, I tended to be somewhat stupid about things like speed, and if I am honest, my common sense was also lacking then, which...

Hi @2old, thanks for the reply. I have been going through the ebikes.ca website. Lot's of information there. However, I have a mailbox across the border, so shopping in the US is also an option for me. BTW, in regard to your name, it's not the age that counts... it's the mileage! :lol...

Hi everyone! I'm looking at converting a mountain bike to an ebike hybrid for my daughter. I already have a 48v lifepo4 battery pack to power the bike. I assume that I will also need a controller for the motor, so recommendations for that would also be appreciated. My daughter weighs...

Hi everyone! I've checked the wiki and perused the site, but it seems I'm trying to do the opposite of what everyone else does! :lol: I need to replace a battery for one of my laptops. Although I can get a new battery for it from China for about $20.00 USD, my past experiences with these...

Hi armandd, I've been busy for the last few weeks, so no updates. But I haven't abandoned the project, I'm hoping to get some work done this month.

OK, I got the swing arm pivot welded in today. The regulator on my welder is bad and I'm waiting on a replacement, so I'm using flux core wire and it sucks! I can't believe how fast I got used to gas! Big difference in the amount of splatter with the welds. I might ask around and see if...

So I finished the pieces for the pivot today. I used a piece of foam board to get the shape I needed for the pivot connector. I rounded the corner and drilled a hole the size of the pivot bolt. Then I mounted it onto the pivot tube: I marked the foam board against the mount on the frame...

I added the support for the pivot to the swing arm: Then I cut and welded the parts to mount the pivot tube to the swing arm: I needed the pivot to stick out so that the two frames won't hit each other when the scooter hit's a bump. I probably over-welded everything, but since this...

:( So in short, no. OK, so I'll rework my design. Thanks amberwolf!

I was at the scrap yard the other day looking for metal when I found these triangles of 1/16" steel: Normally I prefer 1/8" or larger for a mount, but since I'm trying to keep the weight down, I decided to pay $2.00 and use them. I really love my local scrap yard. They have a literal hill of...

Hi everyone! :) I've been asking questions on this forum for a while, and I thought I should contribute to the community that has been giving me so much assistance.I'm already posting this on another forum, but maybe some of the techniques that I'm using might help someone else, (and maybe...

A follow up question, if I may :? I'm looking at the design of my build and it would work better if I stacked the battery cells like this: I realize/understand that the board on the top: is there to facilitate the connections of the battery leads. I'm sure that I could fabricate a new...

Thanks! I guess I was using the wrong search phrases! :shock: :shock: Thanks for that bit of information! It's always the little details like that that end up nailing you! Fortunately, I kept all of the original packaging from when I disassembled the battery. I reused the yellow plastic...

Thanks amberwolf! BTW, do you know where I can get some shrink wrap for the pack? I'm using packing tape right now, not sure how good that is for the long term! ;)

I hooked up everything according to the schematic that I made and all of the light come on now. :D :D This just leaves "D-". On the original BMS, "D-" went to the key switch: It's hard to see on the picture, but the black lead from "D-" is spliced into the red wire going to the key...
