Will this 12V boost theory work

[SP-Electronics]

Wow, as I typed that and edited the image, a LOT of posts popped up, so the same thing was already said. Shucks, I thought I was ahead of the game... lol

The method Roady89 mentions is definitely a much better way to do things, and saves space/weight.

You can't do it on a controller cart...first it would have to be 36-72 volt controller, then You would have to kill 36 volt power to the controller, switch, then apply 72 power back to it. It's not as easy as I just explained it. I'm sure it "could" be done but you could loose a second or 2 in an 8th mile. LOL!

You could theoretically add a couple of solenoids to add an extra battery though.

Thanks
Yeah I finally figured that out from Roady's posts. I was wondering if someone makes one solenoid that would perform both actions of disconnect and connect the 2 cables at the same time with the flip of a switch. I bet there is a solenoid like that, just never had the need to find or use one, time to start searching.

Ok on Roady's design--heres a back to electronics101 question. The motor running on 2 parallel packs of 36 Volts...not getting any more speed than if running on one pack right? But you get tons more torque and power out of the motor on 2 parallel packs, am I correct in this thinking?? The extra speed(rpm's) comes from the extra voltage(72V in series) which would give the increase in speed. Do I have this right????

[SP-Electronics]

Theoretically more torque (limited by the capability of the rest of the system of course), but you could get more "range" out of the parallel setup. But to answer the basic question, YES.

Would this work? Instead of using a solenoid, take the last position of the v-glide and run it through that extra battery which would connect directly to the motor. The high speed boost would always be 100% though at full throttle.

Hey, I didn't want to be left out without a drawing either!

they were selling kits on E-Bay a whiles back that was similar to what your wanting to do and what it did was give you a short burst of speed but it also did some nice motor damage as well if i remember right...............i would put that one in the scrap book and when the gran kids are on your lap you can say hey kids i alm,ost did that years ago..............................lolol............ ....i would leave well enough alone......................................

Sounds like a feasible idea but I'm not sure I would want that extra voltage there at all times. That was a very good solution though. I would like it for passing other people and coming out of the cart path tunnels and going up the hills. I did some research on the solenoids and found they are available. Called a 6 terminal, 48V and white rogers makes one, but here's the question on that.

In reality, not on paper and specs., do you think these white rogers HD solenoids can handle the extra voltage across the contact area for short periods, and keep the switching/activation circuit hooked to the 48V pack

Is there a better recommended solenoid.

Im listening to all thoughts here but I have a rebuttle question per say..
I have seen lots of posts saying these old 36V motors can handle 72V and then some. If I am just adding the occasional 12V for very short bursts occasionally, what would the damage be, would damage be caused by the sudden increase in Voltage? Im just not understanding the potential problem, and enjoy these discussions

....and we all know "well enough" is never enough

Then do the same thing using another F&R switch like used with the EMP motors. One position would be for the original setup and the other would be for the extra 12 volts. From the VGuide to the F&R F position for the original setup and from the VGuide to the R position for the extra 12 volt battery.
