Making Razor MX125 electric kids motorcycle Faster DIY Dewalt 20V drill lithium Battery Pack upgrade

Upgrading Razor MX125 electric kids motorcycle DIY Dewalt 20V drill lithium Battery Pack

This upgrade worked out perfect for my daughter. She got older and heavier, so she wasn’t able to ride it anymore. Now that it has been converted to a dewalt battery pack, she can keep riding for hours.

If your motorcycle trips a breaker while riding, you might need to bypass your rocker switch with a 30amp fuse. Some mx125 motorcycles came with a 13amp circuit breaker built into the rocker switch.

Parts needed

Battery pack adapter

30 amp fuse

Female quick connectors

Electrical tape

Double sided tape

20v dewalt battery pack

Tools

Phillips screw driver

Drill

Grinding Bit

Wire cutter/crimpper

Hello, how much does it run?, and how long does the battery last, and I would like to know if you can put a link back for the dewalt battery adapter, the one you are using to connect the battery and then to the motorcycle razor

[terrellmarshall]

Never mind. Just saw the list in your description

[chrislaws]

Does swapping out the batteries also increase the bike's torque? What if i was to use two batteries? My little nephew has one and it can barely even pull him up a slight hill. Or would i need to swap out the motor to increase the torque?

[jovanberry]

NICEEEE!! I’m getting one of these bikes for my little man, and might want to upgrade if it’s too slow. This seems more affordable and like a fun dad hack.

[victorlani]

Do you need a low voltage cut off switch to avoid over discharging the Dewalt battery?

[slowbalt]

Ah a little dangerous but fun lmao such a dad response. This is exactly what i have planned for my sons sx125. Bout how much faster do you think it is over stock? Stock maxes out at 8mph. It wont even climb little hills in the yard. I have an abundance of 5ah Milwaukee batteries. I think i could get one rigged up.

[twedipops]

hows it holding up? is the 12v speed controller still working after a bit of use

[wickederzero]

Can you hook two batteries to it for longer power or will that overcharge the motor I eventually want to upgrade it with the larger motor from your other video so I'm just curious if I could go ahead and use the double harness for the future project now rather than having to to buy two harnesses for two different projects also the link takes you to a smaller lithium battery with 4ah but the one in your video is thicker can I buy a larger ah battery

[TheHmongol]

If you ride it till the dewalt battery dies. Does it damage the engine or battery? Also does the dewalt batter alao increase the speed

[malcolmmaxwell-frechette]

I modified a moped version of this and I don’t know why it has virtually no power anymore but the batter seems connected with power on

[LandryShift]

Is the adapter compatible with a 20v black and decker battery? The only one on amazon i see for black and decker says 40v

[jakenoland]

What controller and throttle did you use

[zstinson]

Hello, i did this with my daughters mx125.. using dewalt 20v 4ah battery.
She can only ride for maybe 10 minutes before it shuts off on her.
Any way to fix this?

[honzaoutrata]

Was a voltage regulator needed from 12V to 20V? The engine must burn out soon, am I right?

[FrankieLigori]

What’s the part that you put the battery in ? Is it the charger

[jonkarnafel]

How long of a run time do you get out of one of these batteries?
