HeyFuture 12V20Ah LiFePO4 Battery for Power Wheels Ride On Toy UpgradeKit

This 12V 20Ah LiFePO4 battery is well built, compact, and works great. I ordered two of them and connected them in series to power my 24V remote control mower. They deliver plenty of power and have impressive capacity for such a compact size. Runtime has been excellent, and the output remains steady even under heavy load.

The built-in 20A BMS works well. When the mower blade becomes overloaded, the BMS quickly cuts power to protect the batteries from excessive current. After the overload is cleared, everything returns to normal, giving me confidence that the batteries are well protected.

One thing to note is that the actual dimensions are approximately 3.9 x 3.7 x 5.9 inches, not 2.6 x 3.7 x 5.9 inches as stated in the listing. Be sure to verify the available space before ordering.

I actually got this to replace a 12V 6Ah battery I was using as an emergency backup solar charger. I hooked this battery to a solar charge controller and it charged up easily with my 25W panel.

I don't have a way to test the capacity, but it is clear that it is a lot better than the 6Ah battery it replaced. I can recharge a lot more items with this battery which will come in handy if we get another prolonged loss of power.

Make sure you understand the size of this battery as it is not the same size as a typical 12V sealed lead acid (SLA) battery. It is about 3.75 by 3.75 by 6 inches. This is just the body and doesn't include the extra that the tabs on top take up. If you are using this for something that has a definite case size, make sure it can handle those dimensions.

This has been a nice add to my emergency power and I appreciate the capacity and protection that this battery offers.

This is an excellent little battery for our old power wheel. 20ah is plenty of runtime and with the included adapter it’s very easy to install! Great price too. I’d order another if needed!

This battery has been an excellent upgrade from the original battery. The batteries provided by the manufacturer are often a joke and you can see the large trays they provide that are empty because they provide the smallest battery possible.
Installation was straightforward, and the included adapter made it easy to connect. The battery charges quickly, and provides noticeably longer run times. Theoretically it shouldn’t be faster but it definitely has more acceleration and while I never measured actual speed it really moves now.

Performance has been very consistent, with plenty of power even after extended use. The built-in protection features provide added peace of mind, and it has held its charge well when not in use.

If you’re looking to upgrade a ride-on toy to a longer-lasting lithium battery, this is a great value. I would definitely recommend it and would purchase it again

This is a fantastic battery that really stands out compared to many others on the market. The LiFePO4 chemistry is ideal for these applications because it is safe, energy dense, and very durable. The only minor limitation is being cautious with cold-weather charging, but for most everyday uses, that is not going to be an issue.

Several things make this unit stand out. First, the physical size is not artificially inflated. Some 20Ah lithium batteries are built with oversized plastic shells just to mimic the look of a traditional lead-acid battery, leaving a lot of empty space inside. This battery avoids that gimmick and provides a dense, space-efficient package that does not waste room.

Second, the spade terminals are solid and interoperable with standard setups, and the included adapter harness makes it easy to connect to various toys and equipment.

Most importantly, it completely nails its capacity rating. While many batteries fall short of their advertised specs, this one tested at exactly 20 amp hours. In testing the BMS low-voltage protection, it cut power right around 11 volts as expected to prevent battery damage, and it performed smoothly during 6Ah charge and discharge testing cycles.

Plusses:
Exact tested capacity of 20Ah matches advertised specs
Tested low-voltage protection cuts power reliably at 11V
Compact design without wasted casing space
Excellent LiFePO4 chemistry for safety and durability
Solid spade terminals with a convenient adapter harness included

Negatives:
Standard cold-weather charging precautions apply

Final verdict: 5 out of 5 stars. One of the best quality batteries I have tested, delivering true capacity and reliable BMS protection in a well-designed compact package at a reasonable price.

I like LiFePO4 for a kids ride-on because it is lighter than the old lead-acid batteries these toys often use and it maintains useful voltage much better through the discharge cycle. This pack is 12V, 20Ah, and includes a 20A BMS for basic battery protection.

Twenty amp-hours is a substantial amount of capacity for a ride-on toy, so this is the kind of upgrade that can noticeably extend usable play time compared with a tired factory battery.

The most important thing before installing it is checking physical dimensions, connector polarity, and charging compatibility. Just because two batteries both say 12V does not mean every charger and connector should automatically be mixed together.

If the ride-on is compatible, this is the kind of battery upgrade I would much rather make than buying another cheap sealed lead-acid pack every couple of years.

I had originally put this in one of my kids’ power wheels but then we had severe storms come thru my area and knock out power for 3 days. I ended up going into the garage and taking the batteries back out to use as backup batteries for things in the house. Coincidentally, the week before the storms I had just ordered battery step down converters to add charge ports onto my daughter’s razor moped. That combined with the battery gave me two usb ports. We plugged in a swamp cooler fan and charged 3 cell phones and after about 15 hours of the fan running straight it still had slightly more than 50% battery left. It held a charge fantastically and couldn’t have come in the mail at a better time! It was around 88 degrees during those 3 days and thanks to these batteries, me and my kids were probably thriving compared to some of my neighbors.

Great quality battery, in build and function. Good option to swap out heavy lead-acid batteries. The output is much more consistent until exhaustion, unlike the typical "slow down" behavior of lead batteries.

Currently running a 12v RV appliance and it is doing well. Planning to buy more of these to build a larger capacity array for longer run times. See pictures for size and weight.

I picked up this battery for my father-in-law to run his fish finder, and so far it has worked out great. It delivered right out of the box and does exactly what we needed it to do.
The build quality feels solid and sturdy. It’s compact, lightweight, and very easy to handle, which made installing it into his setup completely painless. The size is practically perfect for portable electronics or smaller projects where you don't want a massive, heavy lead-acid battery weighing everything down.
Performance-wise, it holds a steady charge throughout a full day out on the water. The power output has been very consistent with no sudden drops, which is exactly what you want for sensitive electronics like a sonar unit.
The only minor catch is that LiFePO4 batteries need a compatible lithium charger to charge properly and reach full capacity. It doesn't come with one, so keep that in mind if you're replacing an old standard battery.
Overall, it’s a reliable, well-made battery that offers great value for the price. Definitely recommended!

These HeyFuture LiFePO4 batteries have been excellent in terms of quality, charging, discharging and capacity. I have the same battery in a 15Ah form-factor, this 20Ah battery is the exact same size, which I really like. The weight of this battery is very light compared to lead-acid batteries, so these are perfect. I use these batteries with solar panels, outdoors so the IP6 waterproof rating, rain and dust are no problem. These batteries have been highly compatible with my LiFePO4 chargers and existing 12v accessories, which is very convenient. I think these batteries are an excellent value for the money given how well they are built and how hard they work.

I have nothing bad to say about this battery. The majority of batteries and power banks I test come in at slightly (and sometimes much) lower than the stated capacity. This was one of the happy outcomes where a 20AH battery came out with 20.5 AH on my tester. After charging it up to about 14.4 V on a lab supply and letting it rest a couple of days, I put on on the load tester with a 2A current draw. You can see the results in the photo.

That's basically all a battery needs to do. The case is plastic, but it feels solid. The connections are standard, and the size and form factor are standard. I can't really wait a year before reviewing it to see how the capacity declines over time, but LiFePO4 is usually good for 2000-6000 cycles battery life. A similar 15AH battery from the same brand came in slightly under it's stated capacity, so there may be some slight variability across the product line. But these are only two samples, so it's difficult to make any accurate predictions on the average.

The price is about average for this capacity and form factor. Given the cycle life compared to lead-acid batteries, this is a pretty good deal. I've had one on my motorcycle for about two years now with zero issues. Check to make sure your application can handle the change if you're switching battery chemistries though. Generally, these can be used to replace AGM or gel cells because the BMS protects them from overcharging, and the voltage is in the right range.

This 12V 20Ah LiFePO4 battery performed even better than expected right out of the box. Running a bench capacity test showed it delivering roughly 5% over its rated capacity, which is always reassuring to see on budget lithium packs. It takes a charge smoothly, balances out nicely, and holds voltage under load without unexpected drops.

The form factor is an exact fit for standard ride-on toy compartments and small utility enclosures. Compared to the heavy, sluggish lead-acid batteries it replaces, the weight savings is massive. It drops right in without modification, making it significantly easier to handle and install while giving vehicles or small 12V setups a noticeable boost in runtime and punch.

If you are looking to upgrade a Power Wheels ride-on, kayak setup, or small portable power box, this pack delivers genuine capacity, low weight, and rock-solid performance.

This battery is LIGHT. This battery is POWERFUL. This battery seems well made.

We got this battery to use in a 12V power box that we use for our fish finder in kayaks and canoes. It has worked well, so far. The 20Ah is enough to last multiple days of the water.

Lithium batteries are different than lead acid battery in that they don't lose power as they are used. With lithium, you get nearly the same power output up until the battery "dies".

Overall, this is a good battery for a good price. Meant for powersports, but so many other uses.

This is a good quality battery. It works good in a child's riding toy. I put this inside a little power wheels and the car runs great. It has battery posts instead of tabs which are good for connecting clips to charge it. Recharging is no problem and so far, the battery has been good for me.

12V 20Ah LiFePO4 Battery for Power Wheels, 2000+ Cycle with 20A BMS

This initial review is based on product inspection and feature evaluation. The LiFePO4 chemistry is a significant upgrade over standard sealed lead-acid batteries commonly found in ride-on toys. Lead-acid batteries typically last only 200-300 cycles, while this lithium battery delivers over 2000 cycles, offering roughly 10 times the lifespan. This makes it a cost-effective investment for families with power wheels, ride-on tractors, and other 12V childrens vehicles.

The built-in 20A Battery Management System is a standout feature providing protection against overcharging, over-discharging, overcurrent, and short circuits. This safety system prevents damage to both the battery and the toy. The BMS includes dustproof, waterproof, and low-temperature cut-off features, designed for harsh environments like sea, rain, humidity, or dusty conditions, ensuring safe use in various weather. The active cell balancing ensures consistent, reliable power delivery.

The specific benefits of LiFePO4 extend beyond longevity. The battery is significantly lighter than a traditional lead-acid battery, which can improve the toy's maneuverability and reduce strain on the motor. It also provides more consistent power output, meaning the ride-on won't slow down as the battery drains, maintaining speed and performance for longer. This is a direct replacement designed to fit most 12V ride-on toys including Power Wheels, Peg Perego, and John Deere tractors.

For best results, use a LiFePO4-specific charger, as standard SLA chargers may not fully charge the battery. The 12-month warranty provides additional peace of mind.

Based on face value, the upgrade to LiFePO4 and the robust BMS set this replacement battery apart from standard SLA options. I will return to update this review after extended use regarding charge retention, real-world runtime, and the durability of the BMS over many charge cycles.

12V 20Ah LiFePO4 Battery for Power Wheels

5 stars because this is a well made battery with Power Wheels plugin adapter. HeyFuture is a good brand in Lifepo4 batteries. I own one of their 100ah batteries I use in a solar setup.
This battery is in the 12v class with 20 amp hours of storage. Compare that to the lead acid battery in the Powe Wheels of 8 to 10 amp hours of power storage. So you get twice the runtime. And Lifepo4 batteries are amazingly safe to use and charge around the home. They are known for their stability and ability to recharge thousands of times.
This battery comes with the same charging adapter that is on the original Power Wheels battery. You can use your current battery charger because the Battery Management System on this Lifepo4 battery handles how the battery charges. It knows when it is fully charged.
Couple things to note. It will take twice as long to charge this battery because it has twice the storage. The Power Wheels charger is a 1 amp charger, so it needs 20 hours to fully recharge a 20 amp hour empty battery. But you get twice the runtime.
If you want to get fancy, you can remove the battery and charge it with a lithium capable battery charger that provides more amps during charging. I used my Noco Genius 5 amp charger. It can fully recharge an empty 20 amp hour battery in 4 hours
Anyway. Great battery.

Great battery. Long lasting charge. Super value for a great replacement battery. It’s a little bigger than the original but last so much longer.

This 20AH Lithium battery was perfect for a chicken coop I have that is too far from the house to use 110 power for. I run lights inside for us and lights outside to put off predators. The battery is recharged with solar power. This battery is small and light and sits in a small cabinet in the coop itself. So far the battery has been performing perfectly and I expect years of service from it. I think the value is with lithium these days do to prices coming down and a much longer life.
