Endless Sphere

This is me.

super clean. I love it.

Look forward to seeing this one come together... should be a beast.

Many have done so. Heaps of builds here... and if you are going to build a bike you are going to need to spend a lot of time reading these forums.

You can build a much better bike than a stealth though... something with good moto rims and tires and at least double the power of a stealth.

make it out of a thermoplastic like polypropylene or HDPE... easy to cut out and you can fold it and shape it using a heat gun or heating element to soften it.

Click the link below to get to the spreadsheet comparing 18650 cells from the major manufacturers...have also posted this on the facebook page, but worth posting here for those that don't participate in that. https://docs.google.com/spreadsheets/d/17ApXk_1YU9SeQkgZaTA5azdbIf4qCPetBF9Zk6JhyzE/edit#gi...

I'd be a buyer at $500

I'd certainly be interested, but your price for a used unit is twice what it's worth.

Sony Vtc6

you have shorted the brake and throttle signal wire...

If it is one of the newer Sine Wave controllers... (which I have experimented with a few of) they all cut out under hard acceleration, which absolutely sucks. In communication with Fany from Kelly she basically admitted that this issue was inherent to the cheap Sine Wave controllers they make (and o...

ok I accept that. But I still don't see the point in welding fuse wire to the cells. It's actually very rare that a single cell would 'blow'... Almost all battery DIY major fails are related to mechanical failure, and by this I mean all types of physical damage - from wiring rubbing or some type of ...

The wire is what breaks, not the connection to the cell. Is exactly what I was getting to - the wire may fracture at that point where it has been spot welded and joins the cell. There is a good chance that the wire is hardened by the intense heat (localized) from the weld, and as such presents a po...

In the search for low resistance, safe battery construction techniques for high power output, this seems to be neither low resistance or robust enough for e-bike/go-kart application. Heat will be an issue because of the resistance of the fuse wire... and I wouldn't trust the wires to maintain contac...

check video please Thanks for the help ! Luc did you notice the temperature bar on the right side on the screen? If the wrong internal thermistor is set (KTY83 or KTY84 in calibration menu) it looks like this, but i don't know if this would solve your problem or not. That is the issue I've faced it...

Hello folks. Got problem with speed limitation. I have miniE and when accelerating it gives me 4kW in boost mode but as soon as I achieve 50km/h power drops to 2-2,5 kW :/ I have set my Skph value to 100km/h but still cannot go faster than 50km/h :( Any thoughts? go into TRACTION CONTROL and set th...

PAS is simple - so 'HALL" type should work..

But it's also shit. If you have an ADAPTTO - throttle control in torque mode is the only way to go. Forget pas.

.

Does anyone know if the BMS draws ANY power if it is plugged to a pack, and everything else is disconnected (ie. sitting on the shelf)

Thx

I'm loving it. When can we buy one?

that would be spectacular!

I still have a faulty Max-E that I purchased on a bike from another ES user a year ago. The controller failed after one light test ride and I have not received a single reply from anyone in my attempts to get it fixed. I’m asking again; can someone please help me get this thing repaired. I am willi...

If you are using copper it of utmost importance to never touch it with bare skin and to clean it thoroughly with isopropal alcohol before spotwelding. Avoid corrosion - oils and acids in the skin are not what you want on the copper, especially when there is current flowing through it. If it has been...

I can parallel a 48v 14.5A ga cels with a 48v 10A 25r cells?
I was convinced that have to be the same cell type...

Don't do it...

What I'm saying is that you will struggle to, if ever, be able to keep them in balance. Great to recycle the cells, but there are inherent issues, which in the worst case may lead to a fire. Hopefully the BMS will work as it should to prevent a cell group getting too high or low by cutting power. Us...

here in lies the problem of building packs from used cells.
