Endless Sphere

Hey guys, i built an electric mauntainboard, because its very hilly where i live sometimes even if i start with 90% charged battery i get my esc's into overvoltage cutoff to not damage my battery. But brakes are gone then and thats a bit of a problem:) Only i thing related i could find was this: htt...

3 years ago i started motorizing my longboard, roughly the same time i heard about Tesla (the genious, not the car) and i was fascinated from the inventions he made already 100 years ago.

PM me when the next run starts pls!

I'm interrested too, pls pm when when they would be available and final costs included shipping to EU.

Wonderfull story about energy:)

it's not a drug

Hey, i need two of those Turnigy SK3 motors https://hobbyking.com/en_us/turnigy-aerodrive-sk3-6374-149kv-brushless-outrunner-motor.html kv doesnt matter, windings and magnets can be broken too, i just need the bearing seat from the big skirt bearing and the alu part behind (where you hold the motor).

also use search function
cheers

Ty^^ but i have some problems with urethane slipping, on my new design this isnt a problem anymore but i need some cnc parts made first

You are so right
Some of the guys from ''the other forum'' definitely gonna die with their e-boards. If they don't do riding them they'll do while charging-.-

GX-16 connectors i like

They are one directional, but they conduct always in reverse direction so they can handle regen.
pls correct me if i'm wrong

they are GX-16 connectors, and are 16mm in diameter

but that doesn't balance anything

This is what it shows me, i tried all baud rates, maybe a defect arduino board?

I have a problem too
Tried it out today, but doesn't work for me. I can't read anything from the RX side in the serial monitor, just some chinese/russian dialekt regardless the baud rate i choose?

For discharge, I plug a cheap lighted volt meter into the battery charge port and if/when that goes OFF, I then know about a potential cell voltage problem even though power is not disrupted going to the bike. It shouldn’t be too hard to rig slightly more elaborate warning lights/buzzer that simply...

Me already curious if they work^^
Still searching some cheap 5S ones...

Any chance to get some higher discharge cells from you in the near future?

What's about this one http://www.ebay.com/itm/Battery-BMS-Protection-PCB-Board-for-3-4-packs-18650-Li-ion-lithium-Battery-Cell/321808046960?_trksid=p2047675.c100623.m-1&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D37577%26meid%3Dc5d68bd357fb4c12bb80f3b731e6b948%26pid%3D100623%26rk%3D...

I have already one of those (white ones) on my actuall pack. use it for charge only and works so far. But what you say about price is totally true, just doubt about size now and maybe to built splitable packs to carry them on flights.

Do you have drawings of them? Stator size and kv?

Should also be possible to stack two of these?

Need 5*2S or 2*5S BMS for a 10S pack.

loacation?

Now with halls you should can do this.
