Regarding the vectrix throttle , i found some patents , And i had read that it works by PMW signal(not analog). I can't attach the file so , here are the links: http://www.google.com/patents/US6724165.

You only need and imax , take the cells from whatever you want and the compare the seconds with mah. IF 10.000 seconds are 2500 mah 5000 seconds are 1250 mah ( for example ). If you wanna try diferent loads change resistors.This method is a great method to test the capacity of recycled laptop...

I'm seeing a lot of people posting about how to by an easy proccess , test the capacity and overall status of the recicled laptop 18650 cells.I'm surprised that in the post that i had seen nobody had seen the discharger that the youtube user "fixitsan" had uploaded some years ago. He invented a...

Ok , so I understand that if i put the FET in another box with copper or aluminum heatsinks it would be enough cooled.The only thing that still intrigues me , is how i can transform the throttle limitation , that reduces throttle when too much voltage sag into another thing or that can be...

By the way , this charger is the one that's in the lithium version of the vectrix.The lithium version has it's oen propietary bms looking for a lifepo4 battery pack , so i suspect that this would not a be a problem , cause in adittion to the fact that the runke is compatible with a bms , a lot...

Now that i have a new firmware , is about 152 volts and 6 amps aprox.But if i get a bigger battery pack i planned to return to the old charging programe that is about 152/153 volts 11,5 A.

My vectrix mounts a runke "gold" charger in it's peak will charge about 1800 w. Now I a have i firmware that's only charging at 1100 watts.The pack will be from 10 KWH to about 17 KWH. Thank you...

The FETS are 20A.But at what voltage? Thank you.

Fetcher: I'don't know if the vectrix killswicthes when braking , but i doubt it.I think the only digital signal tha the brakes implies , the launch sequence , a kind of security password by pressing the levers to ignitethe vectrix.If if daisy chain to obtain feedback for the 37s//38s , have i...

So , my name is Albert and i live in Barcelona.I'm a proud owner of a vectrix maxiscooter , and 6000 18650 recicled laptop cells I'm testing.So my question is if i can modify the resistors on the bms board to work with a pack of 7 kwh to 20 kwh? The nominal tension of thepack would be 137 volts...
