Power Wheels – Milwaukee Battery Run-time Tests & Low Voltage Protection Installation

By Rich D January 23, 2020 January 23, 2020 Video Project

How long do the Milwaukee batteries we installed into the Power Wheels Jeep last? And – what about battery over discharge protection?

I finally run some real-world run-time tests on the Jeep, and installed a much asked for battery discharge monitor to protect from under voltage!

Cheers!

Power Wheels – Milwaukee 18 Volt Battery Upgrade!

By Rich D August 5, 2019 August 5, 2019 Video Project

Tired of your kid’s Power Wheels battery crapping out after 20 minutes?

Angry because you removed that 10 pound brick and charged it overnight, only to have it die again halfway down the block the next day?

I was too, so I removed the stock battery, and installed a pair of Milwaukee 18 volt Red Lithium batteries in its place.

Check out the full project video below. Links to components used in the project, as well as schematics and drawings follow.

Cheers!
