Compatible with Razor Crazy Cart Rechargeable 1 Set High Performance Replacement Batteries + Wiring Harness (This Does not fit The Razor Crazy Cart Shift) Beiter DC Power

So far, so good. Works perfectly for the Krazy Kart. I did notice that they charge extremely fast. So a huge thumbs up for that

Works as promised. Crazy Cart is working again like new and the kids are back to zipping around the neighborhood.

Fast delivery, and the right product for my Crazy Kart!

So far the batteries are working good although one of the plug/terminal connectors popped off the first time my daughter took it for a spin after a full charge. Had to do a little modification to make the connections tighter. The original batteries had small zip ties to help with the tight fit in the compartment but the new battery cable kit did not come with them. I would suggest the company throw a couple in there given they are charging about 30% more than some competitors online. To include the price of these batteries. Mosterscooterparts.com has much better pricing overall.

The battery starts slowing down after 30 minutes! It still gives my daughters an additional 20 minutes than the old battery.

So far so good it’s been a few weeks since my purchase, no problems it charges great.

I like that it had the wiring because I bought a used crazy cart and previous owner hot wired it. It works great now

Arrived as described and well worth paying the extra for the wire harness, delivery was on time and packaged well.
