Re: Nucular electronics - complete kit for ev! [beta]

I don't mean to sound like an ass but iron losses are pretty negligent. I have plenty of experience with overvolting motors, generally up to 40V more than design.

If you want to talk about losses then look at field weakening :!:

Re: bluetooth BMS?

There is no hardware difference, just change the appropriate values and you are good to go.

If you bought a BMS with the wrong cell count it is a bit more difficult to set up.

Re: Need help with programming a Lingbo controller on my scooter

Doesn't look like there is a Bluetooth option, not sure since I never owned any of those Golden Motor products.

Re: bluetooth BMS?

I made this mistake once,
IIRC I changed the shunt value to something like 2.5mOhm and then did a current calibration at 10A discharge and 5A charge and all was good again.
It wasn't any more accurate than it was previously btw.

The Domino throttle is a Potentiometer throttle, change the throttle type in the Kelly app.

Re: low temp error on my BMS

Maybe it's a wrong throttle type setting, try switching it to the other value indicated in the comment box.

Did you do the Hall Angle identification?

I've had that happen once after swapping my tire and I reconnected the phase wires in a different order.

How cheap?
what wattage do you want roughly?
Do you mean 84V nominal or fully charged?

I might have something.

Re: 50cc Derbi Senda conversion

I've thought about all the mounting positions already, it would rub against the tire with just a small bump on the road. I was thinking of maybe placing a small 18650 pack in there, about 1 Kwh as a range extender. I'd flip a switch and it engages a DC-DC boost converter :lol: My guess is that it go...

Re: 50cc Derbi Senda conversion

Thanks guys, it's the QS 3000 138.
Right now I'm using a 36V LG Chem battery.
I really want to use two of the 12S Samsung SDI batteries in series.

Problem is the space, I'll have to do some cutting and welding... Which I'm not too stoked about :?

Re: Nucular electronics - complete kit for ev! [beta]

Please demonstrate a 80-100 running @13Kw uphill, I'll wait. I have nothing against peak power it's just annoying when people leave out the fact that their motor did 13Kw for a fraction of a second. I can also take a large controller and slap it on a small motor and say it did 15kw... for .5 seconds...

Re: Votol EM-100 & EM-150 controllers

Usually I'd say just put one 10A fuse on the 12V line, but if you are extra paranoid you can put a 2-3A fuse on the 72V line.
There is no point putting one on GND.
