Hello,
My goal is to build a stand up scooter.
I wish i could build a custom scooter chassis, but I dont have the equipment.
I found a frame on alibaba that I plan on purchasing and using.
The frame looks nice, and has enough space to fit the battery I want to put in.
The main goal of this project is to get some practice building a battery, I have developed a keen intrerest in the ebike scene for the last year
I've given this some thought, and want to get the main components first then worry about the smaller things.
Here is a list of the components i plan on using, please feel free to recommend stuff, as I've been putting this together in my downtime and I want to chose the most efficient products.
Scooter Build List
Frame: https://www.alibaba.com/product-det...ml?spm=a2700.shop_plgr.41413.9.69be5d7cpucoi1 This has a 150mm wheel dropout. I hope it is truly forged aluminum
Motors:https://www.uumotor.com/11-inch-detachable-3000w-3500w-electric-scooter-motor.html Specifically the 60V 3000W 145mm dropout size with a 210mm shaft, I was planning on putting small bushings to fill the gap.
Motor Controllers:https://www.uumotor.com/programable-60v-50a-sine-wave-brushless-motor-controller.html This controller is the only 50A continuous controller I could find available to buy.
Cells:https://www.18650batterystore.com/products/samsung-40t?variant=37119892816023 I Already have 50 of these cells, my plan was to buy more to make a 60V, 16s5p pack.
BMS:https://www.aliexpress.com/item/400...1;69.61;-1;-1@salePrice;USD;search-mainSearch This is where I get confused, this BMS is rated to discharge at 100a, I know that having a BMS for these cells is important for charging and balancing, but if i add a physical switch to bypass the BMS for discharge, can I get away with using this BMS? Im just nervous ill trip an overload switch or something of the sort.
Throttle/Display:This is still TBD, I know that there is no industry standard for this, so I dont know how I would go about finding a compatible display to go with the controller.
These are all the parts for now, Please let me know what else I need to get the thing running.
I know that this build is very dumb, and an ebike would be much better with these specs, but I want to build it for the practice and frankly because I love riding around on the scooter.
The motors and controllers are shipped by the same company, UUmotor. I'm not sure about their products but they look real and from what I see, these are perfect for my application,
I have to buy another 50 cells to make my pack, but I will be able to fit the cells within the chassis that I sent.
Please let me know if everything is compatible, and some suggestions for a throttle if anyone has had experience with that brand of controller.
Thank you for reading this,
