ive had a single 40 volt 6ah battery on sons razor for years I didn't know how to stop it from tripping battery so he had been riding just easing throttle to full speed thanks man!
This is a great video! I've been working on the upgrade and was curious if there was a reason you didn't just mount the battery mounts on the bottom yellow tray. You might have to bend the lip down but that shouldn't be to hard. This way we could fit bigger batteries in and the mounts are attached to something even more sturdy. Thanks for your thoughts!
I would also suggest soldering your battery wire connections and use some shrink tube over the connections. It will lower the resistance and also protect from anything possibly shorting out if one of those wire nuts popped off. Lipo fires go up really fast if something shorts out and hate to see your little one get hurt or burnt.
This is a great upgrade, but wire nuts are not a good choice. Those electrical connections should be soldered and coated to prevent contact with anything. Wire nuts are made to be used in a static environment.
So i just added 1 40v battery to my kids razor 500 quad thats 36v, BUT it keeps shutting off on full throttle....so are you saying by just adding another battery....it will stop doing this???? Wonder if i could add an 18v ryobi with the 40v ??
Yes. Two batteries in parallel fixes the shutting off problem. If you really only want one battery you can also use a speed control knob. I show this in another video where I'm working on a razor quad. But iI think the two batteries is a better solution if you have the room for it.
So does it just stop working when you run out of batteries? Because I thought it can drain your battery so much that the battery will not charge anymore? The reason why I ask is I did a power wheels mod with drill batteries and I needed to get a voltage cutoff switch to prevent the battery from going down lower than a certain amount of volts.
I am not aware of any damage being done to the batteries. My guess is that the bike will stop moving before the batteries are fully discharged. I've been using the same batteries for several years now and none of them have stopped charging.
I am worried about different batterie voltage depending on charge level. Do both batteries have to have the same charge level when you put them in? Definitely would put in 30A fuse between the two red wires to avoid any damage to the batteries due to voltage imbalance.
Great video! I just had a question, do you need to match the volts of the batteries to the volts of the motor/controller? I see you are running 40v batteries while the motor and motor controller are only 36v. Will adding more volts make it last longer? Currently I have two 18v Makita batteries on my setup but I'm wondering if adding more will make it last longer? I'm assuming it would make it last longer but the motor won't go any faster than 36v.
I have heard that the controllers can handle much more than 36 volts. I've been running 40 volts for a long time with no issues. But if you do run much higher voltages you do run the risk of burning out your controller. If you want the battery to last longer you need more amp hours. The way to get amp hours is to wire your batteries in parallel. That adds together the amp hours of both batteries and the voltage remains the same. However if you wire them in series you add together their voltages and the amp hours stay the same. If you wired them in series it would go faster but not longer.
@@otislopez33 My kids ride around 40 min before the batteries need changed. The property is pretty hilly though. It's going to vary wildly depending on the terrain and the weight of your kids. But the best part about this setup is you can easily swap out the batteries whenever you need to.
@@showandtelltechnology @Chis watson you mention that you if you run in parallel that voltage stays the same right? So you wrote here you are running 40v but these are 20v batteries in parallel, so arent they only running 20v? U mention that AH will be higher in parallel like this, but not voltage. Am i reading this incorrectly?
Can i run these batteries in series safely please i want to run my 72v motor with two 40v in series without causing a dumpster fire ive already taken it for a 35 minute test ride with no malfunction and the batteries drained one bar at a time on each battery which to me seems pretty evenly discharging i just need some input please and thank you
I watched your video on the Razor Quad 500 as well. So, do you think the controller needs to be replaced, if I convert it to two Ryobi 40v batteries or will the stock controller/throttle work? Thank you in advance
The 36 volt ones don't need their controllers upgraded. I ran my 24 volt quad on one 40 volt ryobi battery for a little while and it seemed to work just fine. I upgraded the controller to 36 volt just to be safe and so I could add some features.
The runtime will be slightly shorter than the stock batteries. In my case I'm going from stock 36 volt 12 amp hour battery to 40 volt 8 amp hour battery. My small boys can ride about 40 minutes on a set of batteries. The real benefit is that you can just swap the batteries out and keep it running all day. We've ridden in the mud a bit and not had any problems. All the electrical connections are still well covered.
So let me ask you this I will assume the orginal on off switch doesn't work now? If that is true as soon as you put the batteries in the bike is on? Is there any way you can cut the power without taking the batteries out?
I upgraded that one to a 36 volt system which came with a new controller and throttle. The throttle has a key that now functions as the on-off and the original on-off switch became forward and reverse.
@@showandtelltechnology can you send me the link of that controller and throttle since you already made it work with the set up I am going to do at least I know what is good for it and don't waste any money buying the wrong parts. But you mean the orignial switch now makes the motor go forward and reverse?
I assume when you disconnected the switch that as soon as the batteries are connected its on so I wanted to still have a switch to cut power if my daughter stops somewhere and wont kill the battery
I have two questions the first one is where do I find those ryobi mounts? and the second once you put 2 40v batteries in the MX650 does it run slower or faster and does it run the same amount of time, longer , or shorter
The ride time is slightly less and the speed is slightly faster. The real benefit is being able to swap out the batteries when they die. With 2 chargers and 4 batteries you can basically keep it running all day.
My bad. I understand what you're asking. Yes it should work. If they were wired in series than the missing batteries would stop the electricity from flowing but seeing as they're wired in parallel having batteries not plugged in shouldn't make any difference.
It lasts about 45 minutes. The ride time is about the same as the original batteries but it is slightly faster and if you have more batteries you can swap them when they die. I was able to keep mine going all day.
No. If you use just one battery it has a safety feature where if they pin the throttle instantly the battery will shut itself off. By wiring two batteries in parallel it prevents that.
I'm afraid I don't know. I've never up to the voltage beyond 40 volts. There's a guy on eBay called overvoltedscooters who would know more about this. He makes upgrade kids and would know what voltages they can handle.
@@lintrailjrdukes6989 the controller and motor at a minimum would need to be swapped for something compatible with a higher voltage setup. The throttle would probably be okay provided the new controller uses the same voltage (5 VDC I think) as the original controller. Otherwise you'll fry everything.
If they were wired in series then yes it would be 80 volt. This is wired in parallel so it remains 40 volt but you add the amp hours together making it 8 amp hours.
way more fun doing this as a Papa than I had as a kid. thanx for the vid.
what a sweet dad made my day watching this
I'm glad you enjoyed it.
ive had a single 40 volt 6ah battery on sons razor for years I didn't know how to stop it from tripping battery so he had been riding just easing throttle to full speed thanks man!
I'm vary glad this helped you. My kids couldn't ride it without tripping the shutoff. Your son follows instructions better than mine clearly.
Did this to 3 of my kid's vehicles, thank you so much for the idea and the time to show us ! :)
I'm very happy you found it helpful.
Did you need to get a voltage cutoff switch to prevent the battery from over draining?
Now this is how these should be made. If you need new batteries just buy and slide them in. No tools needed.
I totally agree!
The electroco upgrade package looks solid
This is a great video! I've been working on the upgrade and was curious if there was a reason you didn't just mount the battery mounts on the bottom yellow tray. You might have to bend the lip down but that shouldn't be to hard. This way we could fit bigger batteries in and the mounts are attached to something even more sturdy. Thanks for your thoughts!
The reason was for access to the buttons on the bottom of the batteries. If you mount it flat to anything you can't get at those.
I bet you could add a car audio Capacitor used with subwoofer amps. That will probably stop the single battery cutting out.
That is very likely. It also might work fine if you used higher amp hour batteries. I've never tried that either. I only have the 4 amp hour ones.
I would also suggest soldering your battery wire connections and use some shrink tube over the connections. It will lower the resistance and also protect from anything possibly shorting out if one of those wire nuts popped off. Lipo fires go up really fast if something shorts out and hate to see your little one get hurt or burnt.
Can you give a longterm update?
What’s the speed and ride time look like??
Amazing video, you earned my subscription
This is a great upgrade, but wire nuts are not a good choice. Those electrical connections should be soldered and coated to prevent contact with anything. Wire nuts are made to be used in a static environment.
Agreed. I wrapped mine in electrical tape as well but soldering is the best method.

How much miles does it go and how fast for your weight
Have you had troubles with over discharging the lithium batteries.
No. I've never noticed anything like that.
Nice guide thank you!
Glad it was helpful!
2 questions, how fast does it go? And where would I connect a new throttle if I were to get one?
It's slightly faster than stock. I think stock was 17mph. The throttle connection must plug into the controller.

Is there any speed increase?
Yes. A slight one.

can i use d walt batteries?
Probably. You just need to find a battery mount to fit those.
what controller and throttle did you use?
The stock ones for this application. They are 36v and handle the 40v batteries just fine.

No. If you use just one battery it has a safety feature where if they pin the throttle instantly the battery will shut itself off. By wiring two batteries in parallel it prevents that.

The electronics appear to be the same so it would work. The way that you mount your batteries will be different though.
Great video except you didn't take it for a test drive!!
