If I was your son I'd off both of those things and buy a Model S Plaid. In a bone stock car Jay Leno just laid down a quarter mile run of 9.23 155mph at Fomosa Raceway. https://www.thedrive.com/news/40921/jay-leno-confirms-tesla-model-s-plaid-set-a-production-car-quarter-mile-record

I had that same one. Grab 3-5 volts off the first series group and run either the positive or negative to a momentary switch. press for 2 seconds (beep) should wake up the Bluetooth in the BMS. Holding for 5 seconds (beep) will depower the charge and output leads. Essentially putting the BMS...

For B+ and B- Ive welded to the nickel strip then soldered the wire on as well as welding a 3rd layer of nickel then soldering. Both worked fine. If it's a really high output pack I'll lay down copper strip on main B+ or B- with my Miller Dynasty 210 Tig set to single pulse with no background...

Here's the one I use. Around $75k and works very well. https://www.youtube.com/watch?v=2l4rB4igFG4

Yes every bump in batt voltage equals more top speed. Ive never been in "limp mode" but the 72150 does limit cold throttle application for the first minute or so of riding as well as the initial throttle application ramp to limit front wheel lift. I run 80-100 battery and 300 phase amps set in...

Ive run 20, 21 and 22s through the 72150 and the mid range torque is pretty incredible. assuming your running 2x6s packs in series? Why not add another 6s series group for 18s? I bet on full charge 75V it'll rip.

13s modules with various size P groups?

Wow this thread is a potential game changer. I have some nickel coated copper strip but the Kweld doesn't seem to weld it. So the two strips need to start life as different pieces correct? People have had luck with .10 Copper and .15 nickel with Weld set to 50 joules?

Yep Im running the EVTV 240v 6kW inverter hooked to some Tesla Model S modules, charged daily by a few kilowatts of solar.

I believe the drop off is from back EMF countering pack voltage. I've found the easiest way to tune, if your interested in performance, is to run from a stop to full throttle 0-30mph, 0-40mph and 100 meter elapsed time via the Dragy. What I do is make a change, then go out and log all three in...

T-Motor is who you are looking for. http://uav-en.tmotor.com I am not currently sponsored by T-Motor, nor use their products at tier 1 MultiGP races. Although they likely make the highest precision propulsion units for quadcopter of virtually any size.

You want to use can bus on a bike? Ive had good luck with the 300 amp ANT bluetooth bms. But it is Chinese.

Gross. I'd part ways with that frame ASAP.

For anyone reading this and thinking "oh dang, I better hurry up and get muh Chinese battery on order...." Stop. If you are reading this it's likely that your bike requires at least 72v 80 amp output battery which requires different design diligence, than say a 48v 20 amp battery. First and...

Is this a skateboard or some other space constraints that limits the P-group to 1?
