12V 12Ah Power Wheel Battery Replacement, Deep Cycle LiFePO4 5000+ Cycles Lithium Iron Phosphate Kids Ride on Toys Battery

Fit my A1 power generator just fine. Will not have to pull that stubborn pull start the next time a hurricane no knocks out power.

Perfect fit. Good battery life. Well worth the money.

Great little battery with really good capacity for my simple needs in a home alarm back up battery. Fit the cabinet easily and was easy to install.

Tested this twice to measure capacity and got ~98% of advertised capacity which is nice. So many of these types of batteries seem to have impossible or incorrect battery capacities listed it was good to see an accurate listing. Tested this up to around 120 watts load in my UPS and it worked fine, the wattage reported on the UPS isn't the most accurate but this battery claims a maximum of 8A for 3 seconds before cutout, which would be 96 watts at 12 volts.Tests @1 amp draw5.84 ah / 74.73 watt hours - 97.3% rated capacity5.91 ah / 75.47 watt hours - 98.5% rated capacityWeight - 826 grams, 1.82 lbLow voltage cutoff tripped at around 9 volts and did NOT automatically recover, I needed to apply a voltage to the battery before the safety turned off, at which point it was back to around 12 volts idle. None of this is outlined in the instructions included in the box, it would be nice to have those specs.

This 12V lithium battery is designed for use in kids’ ride-on toys, camping, and other applications requiring a reliable power source. With 18 Ah capacity and bolt terminals (M6), it provides a long-lasting, lightweight alternative to traditional lead-acid batteries. The LiFePO4 technology offers enhanced safety and durability.

I'm using this as a power storage for an LED lamp. Because of its protected circuitry I feel safe pairing it with a solar charge controller for emergency lighting. These are marketed for power wheels I believe, however the functionality does not need to be limited as such. This high capacity to size ratio means that this can be used in many applications requiring constant power delivery over a long time. I found that the overcurrent protection does work during a few loads testing experiments using a pocket inverter to power a TV and it turned off. As such this is probably not suitable for high amperage applications. I'm looking to potentially run a few of these in parallel for a 12v 14 battery configuration for a ~1kwh emergency power supply that can be coupled with a RV AC inverter for a custom solar generator. I already have 200W of solar panels that could potentially produce that much daily. Building your own could save a significant amount over money over buying a solar generator kit if you have the confidence and know how to do so. The uses for a versatile battery pack like this are almost unlimited.What I like about it:Size and light weightOverall valueQuality look and feelHigh CapacityWhat I think could be improved:Documentation is lacking specifications for overcurrent shutoff, or max supported current.

These arrived well packaged, work fine, and are fairly lightweight.These batteries are not a drop in replacement for other types of battery chemistry such as lead acid gel, LiCo, LiMn, etc, commonly used in things like UPS systems, cell phones, portable battery chargers.These are LiFePo4 batteries and as such need to be charged differently than lead acid / gel batteries, or other types of lithium chemistry. Taken care of properly, LiFePO4 batteries can last much longer than other chemistries, but how they are charged is essential to maximizing their useful life.I charged them at a rate of 1.5A or about 0.25C and the BMS did cut off when they were fully charged. I set the maximum charge voltage as 14.6, however I didn't track exactly what the voltage was when the BMS stopped the charge. This took about 2 hours so they were sent with a reasonable amount of charge. I then did a discharge capacity test which I stopped when the voltage reached 12.8 so there was likely a little bit still left. Stopping at 12.8, I got 5.54Ah out of them, if pushed harder to a lower voltage I expect they would deliver the full 6Ah rating.

I'm giving this five stars even though it didn't work for my needs. I was trying to do something that this battery isn't necessarily designed for. Not the fault of the battery at all. After my mismanagement of using it, I was able to charge the battery back up and it is still seemingly working fine. I'll find someone who needs it and pass it along.
