Universal Power Group 2-Pack of 12V 7.5Ah SLA Batteries for Razor MX350 Dirt Rocket Electric Motorbike

Jessica: The batteries arrived quickly and fairly easy to install. I had to go and pick up a few accessories at local store because I don’t own a soldering iron.

augustine vegas: works great but you will need a wiring kit or I just bought a couple crimping terminal connectors for $3, then cut the wires off the old battery close to the terminals, then added the crimping connectors the cut wire ends.

Ron: This was the exact thing I needed for my daughters Razor MX350. The tire would not spin even with a full charge (verified with a multi-meter) although I could hear the electric motor hum a little. As soon as I put the new batteries on the bike it cranked like new.

I considered purchasing a replacement harness for the batteries because the original wires are soldered on but when I saw that the terminals on the new batteries were the same size as regular spade terminals I figured I could do it myself. All I did was snip off each wire as close as possible to the old connector then strip the wire back 1/4". I then used some nylon insulated female spade connectors I had in my toolbox on the end of each wire. It took all of 10 min. and saved me alot of money.

M Bernier: The battery's worked great, after we bought a different harness since the one we purchased with these doesn't work for the mx350.

dlw: These replacement batteries for our grandson's Razor works just like the originals. Good price too. Be sure in fully charge and then run down until totally dead the first few times. That way the batteries will last longer.
