I wish there was a like button here so I could give you a tip of the hat w/o cluttering up the forum with thank you or nice work posts for all the awesome things here but anyway... crusher... thank you for these diagrams and all of your awesome contributions you are probably currently the most active/helpful member here that really makes this forum what it is. Good work.

[jonesee]

I give a huge second thumbs up too. Crusher has been a huge help to me and a priceless asset to this site.

[toycrusher]

Thanks guys! I've accepted that I don't have the skills, time, or money to do half the things I would like. But I do have ideas I love this forum, the chance you all provide to be a small part of some really amazing creations, or just helping put a smile back on kids faces when their rides come roaring back to life

I just realized I didn't finish posting diagrams or descriptions here Back to work!

High current bypass for any BPRO. A pair of SPDT relays handle the high motor load. Provides forwards, reverse, and integrated braking.

**Caution: Gearbox destruction is likely at higher voltages. It shock loads the system with FULL amperage **

An ESC can be run inline to solve the shock load problem, but a micro switch would need to be added to the variable pedal to activate the relays and release the brake

[ardillagrilla]

Wow...i have to say thumbs up crusher...thats a great help for guys with no experience like me ...and even tho that i quiet dont understand them all im learning a lot from this..keep up the good work man..!!

*** Quite a few of the 6v remote control Chinese rides showing up with horribly slow performance ***

This provides 12v to the single rear motor. It will likely hold up well with smaller riders It retains the original kid control and remote control features, as well as lights, mp3, and anything else that came on it originally.

** Note, this diagram requires 6v relays. It may not function when using typical 12v automotive relays

[realred2]

I have a 12v version of the Chinese (Lambo Aventador) that I would love to speed up. I'd prefer not to re build it completely at this time, is there something similar with the 12v version as the last diagram for the 6 volt version? Give it more speed, but keep control and sound?
Thanks.!

[toycrusher]

Yup, exact same diagram will work

[realred2]

Thanks, I just need to add 2 relays (I have a bunch from my old Car audio system) and a fuse for the new battery and He will be cruising faster? The 12v one I have has two motors, do I split the outputs from the relays or do I need to add 2 relays per motor? Thanks!

[toycrusher]

Just split the output from the relays. Also, just use the 12v leads from one of the motors to trigger the relays. The other set you can eliminate

[Coopz]

Hey toycrusher is there any revised wiring diagrams for a 18v set up using 3 X 6v batteries,using a 6v (mostly likely a 6amp)charger? I did read another post regarding this type of set up,just wondering if that diagram still is the best one. Involved 3 relays.
Cheers

Nothing new on that front. Members have done it with switches, relays, and my favorite, a 7 way trailer plug

Been trying to figure out something on this diagram. What's the device with the two bolts on the right side underneath the top 6V battery?

That's a resettable circuit breaker. You could put a fuse there instead

[flyingmoose99]

Hi. I'm new to this and I think I have already fried my first board. I have the avigo BMW X5 (http://www.rollplay.net/products/view/6v-bmw-x5). I added 3 x 12v 7ah batteries in parallel each with a fuse on the positive wire (5 in total including the wires connecting the batteries), another 6v motor which I have added using a 2 to 1 adapter I made. Which goes into the stock pc board. All was well until today when it stopped. Lights work, radio but when accelerator is pressed motors just click.

Any chance you could let me know how to wire it without damaging the new board that's on the way? But keep the two motors and batteries? My kids were loving the power ...

[toycrusher]

Scroll up a few posts. It's the last diagram in the thread and it will work for you

[flyingmoose99]

Thanks so much for getting back to me. I have created a wiring diagram of my current setup. Like I said before i'm pretty sure it's fried (testing everything with the voltage meter tomorrow) but considering i only have mp3 player and remote steering still working unlikely it could be much else. Thanks for directing me to your diagram but I'm a complete noob and struggled to follow it in regards to my setup. Do you think you could scribble on the image and show me what i need to add to stop me from frying another circuit board please? Also do you know of any 12v circuit boards from another model that I could use instead where I could plug everything into, retain all of the current features but leave me with no risk of frying it?

[toycrusher]

Your almost there. Replace your 12v batteries with a single 6v. The wires that currently go to your motors need to go instead to the green and blue wires in my diagram that read "connect to original motor leads". Wire up the rest with relays as shown and your good to go

[flyingmoose99]

So there is no way to keep my 3 x 12v batteries? I have to remove them completely from my set up? I really don't want to as with only a single 6v I would have little to no power or run-time...

[flyingmoose99]

Ok so a further update. Went over the car with a volt meter and turns out i have blowen the relays on the pc board. I was pumping 21+ amps though the relays that could only take 10 amps. So i'm going to get a fresh board and replace these relays that are currently on the board http://www.futureelectronics.com/en/tec ... 2-1ZST(257).aspx?IM=0

With these http://www.jaycar.com.au/30-amp-spdt-re ... e/p/SY4072 which can take 30 amps

Those batteries would take the place of the second 6v in the diagram giving you 18v power! The 6v is necessary for the board to survive, the relays handle all the current giving power to your motors but protecting the circuit board.

[flyingmoose99]

OK cool. yeah like i said i'm replacing the relays on the board. i'll let you know how that goes...

[Suburbancharlie77]

I'm referring you out Mr Crusher.
Any input on this?

He's looking for a motor/gearbox, and speed. Has pictures available, but is in Portugal.
I'm almost thinking adding relays and boosting voltage to a single Chinese is pretty much all he can do. =(
His pictures...

Ordering parts, especially tires, with shipping is going to be killer! If our guys would even send international???

Would it be possible if someone could take a picture of a car that has this set up? I'm not entirely sure what some of the wires coming out of the relays look like. Sorry...still a newbie at all this but I'm trying really hard to learn all this.
Edit: I watched this video

and it helped me get a better understanding of relays and what it looks like. The diagram looks different as there is 2 relays and 3 batteries involved, so if anyone still has a picture i would greatly appreciate it!!!!!

[Suburbancharlie77]

Tutu, the relays are something that you are providing. To utilize the existing gas pedal and shifter. The relays are activated by the shifter. Unless someone found the exact same car that you have, the wires are different.

[jackytutu]

Oh okay. I had the impression that they were in the car already. Thank you! once again, sorry for all the questions suburbancharlie. You have been a great help. Expect more questions to come though! :D:D

[Suburbancharlie77]

It's kinda small or tiny print, but the relays are"fed" by the original motor wires. I dunno if you can print just that image, but it should be a bit bigger, and definitely would be handy to have the ability to glance up at it taped to the wall, while working on it!

Don't thank me, thanks all go to toycrusher!

And no worries, we all learn at some point. And those that don't, we'll I try to avoid them =0

[jackytutu]

wait, so the relays ARE in the car already? or were you just saying that the wires that have to connect to the relays will come from the original motors?

[Suburbancharlie77]

You take the original motor wires, and they act as a "controller" for the relays that you are adding.

The relays will control the voltage that the original equipment CAN NOT HANDLE. The stock design will typically fry when you double the voltage to the sensitive circuit boards.

The motors tend to be far more tolerant of the over voltage, matter of fact, there are even some members running 24 volts without issue, to even some of the 6 volt motors. Personally I've been maxing at 18 volt, but not much of what I own is from this decade. Old worn motors don't take kindly to an adult and 24V, ask my sister in law, that burn up smoke stunk like holy heck and lingered!

@toycrusher ..
need some help please. I'm not an elec buff, but your diagram is quite simple to understand.
As far as what I can tell, I connected the everything as per your diagram.
After connecting everything up .. the RC still works .. wheels turn left/right, but the motor is not working .. when i press forward/reverse .. all I hear is this clicking sound ..the same effect when the pedal is pressed.

After this I can up last night .. will try and determinate the location of the fault.

Any suggestions on what it could be?

Thanks

The low current side is working, the relays are switching. It's the high current side that's missing a link

I know this is a bit of an old post, but hopefully I can still get some help as Im not electrical inclined .. well not so much .. I have common sense tho
So I did the wiring according to Toycrashers' diagram, but not getting 12v on the motor.

I took some measurements and this is what I am getting
87/87A -> 12v
86 + pedal = 6v
30/87 = 12v
85/87a = 6v
85/87 = 6v
30 + pedal = 0v

for me it looks like the relay is not switching from 87a to 87 when the pedal is pressed an 6v is sent to the relay

relay.jpg (32.11 KiB) Viewed 2726 times

am I using the wrong relay, is it not switching because 6v is being sent to 86 and this is a 12v relay?

[toycrusher]

My diagram runs under the assumption that your relay will switch with 6v applied. It has seemed to work for me but it's entirely possible that some relays will not trip with only 6v.

If you were to swap to these relays you should not have a problem. I am going to make an edit at the beginning of this thread. Sorry for the misdirection

[Hammer-fm]

FWIW, my 40A DPDT relay fails to switch at anything below ~7.5V . I was testing it the other day to see exactly how low I could go, since I was using a linear regulator to power it and wanted to minimize heat production -- lower voltage means less current draw -- less power wasted in the regulator.

The spec sheets seems to generally fall in the 8-10V "guaranteed" range. Some list a guaranteed turn-off voltage -- often below 2V ). For instance the Magnecraft datasheet here shows 80% of nominal coil voltage as the lowest guaranteed turn-on, and 10% of nominal as the lowest guaranteed turn-off [drop-out]; they have others that are 75%/10%, respectively).

[Neilvdm]

Thanks for confirming my thoughts.

I'll order 2 6vdc relays

[Neilvdm]

Seeing I have to wait about 10 days to get the relays here in Qatar .. what would the implications be if I added voltage inline with 86?
For arguments sake, a 6v battery, then when the pedal is pressed and the original 6v sent, 12v would reach 86

Something like this .. but after looking at this, my wiring here is in parallel and not serie ..

if this idea will work, what would the correct serie connection be?

[toycrusher]

I can't see why an inline 9v battery wouldn't do the trick temporarily

[Kidcars=dadstoys]

Hello, new to the form.. First I'd like to say thank you for all the awesome info you guys have made available.. Truly great posts.. We bought my son a car from best choice he loves it and we like the rc function.. it's just far too slow.. I feel pretty confident using the diagram that crusher posted for over volting without frying the board.. There's just one component I'm not sure of.. Maybe someone can identify it.. Thanks guys

[Neilvdm]

thats 12v relay it looks like. What is the size battery is the car fitted with? 6v?

[Kidcars=dadstoys]

It's a 12 volt 7 ah.. Here's a picture of that component from the top.. seems a bit narrow even for a mini relay.. one leg goes straight to the positive side of the battery the other goes out the back to the charger port..

[Neilvdm]

Yes you are right, best then to wait for the experts to reply
The only other thing I could think is that it regulates the battery charge?

[Kidcars=dadstoys]

Yeah I was kinda leaning toward that as well.. Just due to it's location in the circuit.. Still not entirely convinced tho... That ought to be the charger's job I would think.. thanks for the reply tho much appreciated.

[toycrusher]

I'm going to guess that that is a circuit breaker. You will probably need to replace it with a 30 amp
