In this video about upgrading our Power Wheels, sit back and relax as I take you on a quick overview of converting my daughter's 12v Power Wheels to Lithium power using two 4s Lipo batteries. Since the conversion I've been averaging about 2ah (2000mah) per mile. So with my two 5400mah batteries in parallel I can go about 5.5 miles on a single charge.

Towel = kindling for fire. HD Velcro is your best bet though. Good video! My 2 year old just got a PW racing quad and I’m already looking into upgrades lol. ML Toys makes assembled steel gear transmissions with upgrade motors fyi. Plug and play!
Smart way to do the soldering!
Just did the same conversion myself, ran with just one lipo for a while til i got bored and made a parallel harness. For the price of these ride ons they should come with lipo.
Hey, how much more runtime did you get with it?
@@jarredjennings4045 thats the thing with 2 4s lipos in parellel ive never had the voltage drop below 3.9 volts a cell and thats after about an hour of continuous use. My best guess is near 2 hours
Lo más fácil que e visto! Muy bueno!
Gracias amigo!
Looks great, rubber air tire swap next!
how about a motor upgrade or variable speed control video?
Hey, my daughter has the same one. How much more runtime did you get vs the stock battery?
It depends on the mah rating of the lipo battery you buy. A 4s 4000mah lipo will have about half the runtime of a 4s 8000mah. The stock power wheels battery is a 12v 9500mah battery, but because of the nature of SLA batteries, will begin to lose quite a bit of power around halfway through the capacity, essentially only being able to truly use around 5000mah before needing to be charged. A lipo battery on the other hand will stay strong through its entire capacity instead of beginning to lose power half way through. As an example, a 4s 9500mah lipo should last about 2x as long as the stock 12v 9500mah SLA battery. 👍🏼 I don’t necessarily buy lipos for increased runtime, but because they give the Powerwheels more pep under load and you pick up a few mph on the top end. They also don’t seem to deteriorate as quickly as the stock SLA battery.
Would it be possible to do both parallel and series with the connections? I know you can make that type of connection with a DIY battery pack which doubles both voltage and Mah.
Yes absolutely.
OH MY GOD who is this little girl? She is adorable!! I have 5 yr old son that's amazing but little girls make the toughest man wear makeup
Yeah, stuff a nice flamable towel in there below your child! Lipo not a great power source for kids toys,at least you need a integrated low power cut off.
Nice video, thanks for the info!
I cannot see where $120 bucks plus wiring is saving the cost of a lead acid battery. I understand why you are going that route but holy man!
RC Hobbyist Extreme Definitely not a cost saving solution. This is geared toward more power/punch, and run time. This solution is cheapest for those people who already have lipos. Thanks for watching! 👍🏼
Stock battery sucks. It's expensive and dies quickly.
Do you know if it is safe to add more than 2 batteries in parallel? e.g. run 3-4 extra batteries using the extra empty space at the back and the front trunk compartment? Also, what is the recharging time on these Lithium Ion batteries, with the stock battery, the manual says 18 hours. Cheers!
You can run many batteries in parallel. You will want them all to be the same voltage and MAH. For example, running four 4s 5000mah lipos in parallel would be fine. You are essentially creating a 4s 20,000mah battery. Just make sure you run a lipo alarm on each lipo! Unhealthy cells drain quicker than healthy cells, and will trip the alarm sooner. Generally lipo batteries are charged at 1c which means the charge rate = the capacity. I charge my 5000mah lipos at 5 amps, a 3500mah lipo at 3.5 amps. There are some lipos that can be charged at 2c or higher depending on the manufacturer rating, but charging at 1c generally extends the life of the cells in a lipo battery. Charging at 1c usually takes around an hour to charge, if your charger is up to the task. Some cheaper chargers can only charge a 4s lipo up to 3 amps. So if you have a 4s 9000mah lipo, its gonna take around 3 hours. More expensive chargers can charge at a higher rate. If you have any further questions on lipo charging and care, I'd recommend some heavy google research before diving into the lipo world. You don't want to burn your house down. Many people charge their lipos in "lipo charging bags", so if the battery explodes it doesn't catch fire everything around it. You also have to take care of lithium batteries. You can't leave them baking in the sun on a hot day in the Powerwheels, or letting them freeze outside in the winter like you can a standard SLA 12v battery. Extreme hot or cold temps can damage them and cause them to "puff" and become volatile. If my kids aren't actively using a powerwheels vehicle, I pull out the lipos and store them in my fridge.
These are not lithium ion they are lithium polymer and yes you could add as many batteries as you want in parallel it will just increase the run time. Not in series tho it would kill the motor and speed controller the minute you plug in if you put to many volts. As for charge time. That depends on your charger. There are many to pick from. I have duo sport pro charger i can charge 2 lipos at max 6amps each. Which would be safe for these. So 2 full lipos in about 1 hour
Great video I checked wit value hobby and batteries are out of stock. No idea if they will get more. Any ideas. Would love to convert my Grandsons.
Johnnie Ludwig I have been getting my lipos recently on Amazon. All sorts of manufacturers. Just check the reviews.
@@MapleBoarder78 Thank you for your help. I looked on Amazon and they were all 7.4v. I did find one that was Gens ace 7500mAh 4s1P HardCase 100c 15.2v Lipo Battery Pack #50 For RC Cars Racing Series. What do you think and with this on would I still put 2 together? Or can you please recommend one on Amazon for me. Johnnie
I found a battery but I do not know what kind of charger to buy. Looked at amazon but still now sure what to buy
Johnnie Ludwig You can run either two 2s lipo batteries with a series connector, or just a single 4s lipo. 4s lipo would be easier. Make sure it’s at least 5000mah or higher, and don’t forget to run a lipo alarm on the balance plug. Here is a link to a charger...

If you haven’t yet, make sure you do extensive research online of how to properly care for and charge lipo batteries. These batteries can be dangerous, people have burned down their garages. I did hours of online research on the remote control car forums like rc tech.net before diving in. You need to understand the chemistry of lithium batteries, what it means to run them in “series” or in “parallel” and what the “cells” of the battery are and how they work. Be safe. ☺️
How do you do this for A 24v real tree utv?
I’d get on Amazon and find a cheap LiFePO4 lithium battery that would fit in the battery compartment and also buy a LiFePO4 charger for it.
Alternatively you could use a standard 6s lipo battery meant for remote control cars/planes.
Links pls on those upgrade items
Unfortunately this video was made 6 years ago and the majority of them no longer exist for purchase. You’ll have to Google a bit to find the parts. You’ll need a 4s lipo with at least 5000mah of capacity, a parallel connector with your specific electrical connectors (many people like XT90 connectors), a low voltage Lipo alarm, and then you’ll need a soldering kit.
link for low voltage detector please
I’m not sure YT allows links. I’ll try to link.

Can Those Batteries be Wired in Series?🤔
Two 2s lipos can be wired in series as long as they have similar mah and C discharge ratings. As long as you don’t exceed 18v on these rigs they run pretty well.
@@MapleBoarder78 Thank you So Much I Was Going to Get Two 775 Gear Boxes For my Son's 24 Volt, Grave Digger? With the Metal Drive Gear?
T
Your Video was Very Helpful
do you not need an inline fuse for this set up?
Good idea if you want to protect something from getting fried if you hook up the wires backward accidentally. I haven't done the math to figure out what size fuse you would need though.
@@MapleBoarder78 i know the other kits for the lead batts use 40amp but not sure if it's the same for lipo batts.
Can you recharge the battery via the stock charging cord?
You can’t. Unfortunately Lipo batteries require a lipo specific charger. If you search “lipo charger” on amazon, there is a great selection of lipo chargers as cheap as $35-$45.
So I did this conversion with (2) 4s 7200mah 60c batteries. Hooked it up to a power wheels police car and the batteries lasted 1 hour, being driven pretty much the whole time. I’m trying to get about 3 hours of run time. Any ideas on how to get there(other than the obvious add more batteries)? The lead acid batteries easily got 1 hour+.
The only way I’ve figured out to extend run time is adding batteries so I’m stumped on that one. Two 7200mah lipo batteries have 14,400mah and I believe most 12v power wheels batteries are around 10,500mah so the lipos should last longer on paper. How low are you draining the cells of the lipo batteries? Around 3.3v per cell? If the lipo alarms are set to 3.85v per cell you will be leaving a lot of run time on the table. Also, are you running each battery separately, or together in parallel? Together in parallel they will have less sag under load and not trip the lipo alarm as early as being run one at a time.
@@sandyvalleygeneralstore8009 what?? how did you get 1 hour of run time on a power wheels stock battery? I just bought one and it starts dying maybe 20 mins in.
Saludos Maples puedes entender el español ?
Es que tengo unas preguntas respeto al tema
i cant find these batteries anywhere
Any 4s lipo over 5000mah will do. A higher discharge rate like 50c + should be used. Here is one on Amazon.

Ok cool thanks for the video
Lithium batteries burn the gears out of even the best motor I can find. Do not use Lithium batteries. They have a discharge rating 5x higher then SLA batteries. With no clutch to absorb all of that extra punch the motors and gears will fail.
Brother can u send me everything u bought for it so I can do the conversion
Hello Bob! This project was so long ago, I can’t remember everything I bought/used. Some of it I didn’t buy as I already had some stuff. Looking back at my video, it looks like you’ll need a male deans connector to solder on and replace the stock Powerwheels battery connector, two 4s lipo batteries with deans connectors, a parallel connector with deans connectors to link the batteries together, and two Lipo alarms to run on each battery. You’ll also need to buy a Lipo battery charger. You can find all this stuff on Amazon. If you are unfamiliar with Lipo battery care and usage, I highly suggest you do a lot of internet research on them. They have to be stored, charged, and discharged in specific ways, otherwise they can be damaged or even catch fire and burn your house down. Good luck with your project!
2 batteries that cost more then the power wheels lol
Haha, exactly! That’s the modding life for ya!😂
Justin bustin my thoughts exactly. That’s why I bought a $12 connector off amazon. Then just hooked it to my one of many dewalt 20volt batteries.
@@bshaw1979 is 20v too much for the motor? Do you have a voltage regulator?
@@Matt18880 no voltage regulator. I just run the 20volt dewalt batteries.With 2 kids in it. For 20 minutes or so at a time on fast. over the entire summer with no issues.
