Endless Sphere

all the packs I have, have the BMS on the very top(on the four top cells)

They don't all look like that I have two other brands that look completely different. Boards not even the same

Why not just run 12s lipo its prob similar priced to a new fw controller? I dont need to stay 10s, the only benefit is the converter working and battery i had

If you replaced the controller with one that does field weakening you could get a higher top speed with the lower voltage battery. I have been pondering this myself, then I need the 12v converter again and lots of extra parts. If anything id like to find something that will fit under the controller...

So that awful 12s battery left me stranded yet again! It just cannot handle the 40a current the controller is demanding...I got sick of it finally and decided to lose some top end speed and put in a 10s battery pack. The pack is made of 80x 18650 cells and is 17.6ah. It is also taller and doesn't fi...

Did a little bit of work to the Zootr scooter proto-type. Changed out the bent front forks with something inexpensive. And while doing so the headset fell into a million little ball bearings so I had to throw a sealed new headset on it. Used a BMX stem upside down and had to order some special lengt...

hahaha thanks for the pics. I have never seen a mini folder without its plastics! They went so ridiculously bulky on materials with these bikes...

This thread is old I don't think he has them anymore

Here you can see where I added a 3s 12ah accessory battery for now. It fits perfectly above to motor battery and is made of the same cells. I just quickly put some XT60 connectors on it, made a 12.6v charger for it and soldered in a quick power tap wire into the left handlebar terminals. So I basica...

Thanks for that EB! I'm sure it will come in handy one day So I decided to move the horn to the center just under the headlight since I might shave the front bracket down but im not sure yet if I want blinkers or not in front so I will keep it for now. Makes it look better either way IMO It helps hi...

Go mid or go home. Especially if your going to use a gas donor bike. The wheels will match already you wont need to change much the chainline and sprockets are there for you. Just need to weld a motor in the correct place. Changing the gearing will be much easier mid Hub motor will be quieter and sl...

Does the motor spin? If not id start by pulling the stator out and cleaning the surface of the magnets and the top of the lams, then youll be able to also see the hall sensors which are set into the top of the lams. To properly test them you need 5vdc and you have spin the motor Looks like a fun...p...

You should try a phaserunner from ebikes.ca they are completely waterproof, programmable, really small with long wires and you can mount the heat sink to your bike frame easily. Its not cheap but you get what you pay for If that is too much you can try Kelly controllers mini ebike series, theyre abo...

I think you did already create a thread! Here it is...Your off to a good start. Good luck on your build but it should be fairly easy to buy a few pieces and slap them together if you have 3-d printing skills. I look forward to seeing the first and only carbon mid drive E build ever! Post some pics i...

I ran my setup with it running like this for a couple of rides before i figured out what was going on, the controller would keep blinking a 3-2 error code when i beat on it, and the problem never stopped. The bike did work somewhat and had plenty of power but was hard to control Freewheel will just ...

Lol buying in bulk smart man!

Got a little work done on the wiring harness of the stock Voloci bike, I took the E brakes off to clean up some wiring, and i'm pretty sure I will not be using any directional in the front so I will cut the bracket down eventually. I soldered and heat shrunk the wiring so now if I ever need to take ...

I completely agree with you, in my head I had plan to use some thin plastic board and cut squares for sides and a bottom. I will have to do that before it goes in the bike and gets banged up!

Little more progress on the battery build. Put the cells in a line and tested the voltages. Lightly compressed them with a clamp and threw a layer of 33+ electrical tape over the bare cells. Then a layer of gorilla tape over that to hold them in place. These cells are not perfect as you can see in t...

The link to the battery says 20s7p where is the 9p coming from? 7 cells in parallel is not alot to push 100a peaks so ya 10v sag with 18650 pulling 10a per cell is normal imo

Bike means anything with two wheels to me. But it is very vaugh terminology Since i got into this hobby 10 years ago and bought my first 48v ebay golden motor hub kit and put in on my GT mountain bike, ive called my projects E-bikes Obviously E meaning electric and bike meaning bicycle Now i also ha...

Does someone actually drive the car or are we finally plugging ourselves into the matrix power grid? The revolution has begun

Yep i had this issue before also the Kls series wouldnt work with my lrhdd motor...tried every setting. Got a Kbs series and now it works perfect. I tried 12v to halls adding diodes in series nothing helped Kls hall signal distortion You can easily see the hall errors in the test portion of the kell...

Oh i actually do like that spot for a charge port. But i will certainly have to source a special type of port and drill holes. One of those wants more than needs type of things.
