How To Upgrade Power Wheels Battery With Lithium LiFePO4 Replacement Battery
The stock lead acid battery that comes with Power Wheels ride-on cars for kids is weak and often dies. A better replacement is a Lithium (LiFePO4) rechargeable battery. A LiFePO4 compatible battery charger must also be used (read below)
BATTERY
These LiFePO4 batteries come with a Power Wheels connector and inline fuse. They are plug-and-play, so you can install them into your Power Wheels.

CHARGER
A LiFePO4 battery requires a charger different from the stock lead acid battery that came with the Power Wheels. Although the battery manufacturer might say that 14.6V is the charging voltage, it's well known that charging to a max voltage of 14.0-14.4V is better. Therefore, buy a LiFePO4 battery charger with a charging voltage within that range.
Victron makes excellent products, and it's what I use for my solar power systems. Their 12V 5A battery charger uses a 14.2V charging voltage on the Lithium battery setting. This is perfect for charging the LiFePO4 batteries shown above.

CHARGER CONNECTOR TO BATTERY CONNECTION
The original charger to battery connector will need to be attached to the new Lithium battery charger. Cut the connector off the original lead acid battery charger cables. The charger comes with a cable with M8 eyelets. There are a few ways to attach the original connector to the new charger cables.
Crimp eyelets to the bare ends of the connector cable. Use machine screws (small bolts) washers and nuts to attach the connector eyelets to the charger eyelets. Use 2 layers of heat shrink or wrap with a generous amount of electric tape to properly insulate the connections.
Cut the eyelets off the charger wire and strip the ends bare. Use a crimp butt splice or heat solder shrink splice to connect the battery charger and the connector wires together.
Cut the eyelets off the charger wire and strip the ends bare. Solder the battery charger and the connector wires together and cover with heat shrink (remember to put the heat shrink over the wires before soldering).
