Mighty Max Battery ML12-12 - 12V 12AH F2 Razor Dirt Bike MX500 Replacement Battery - 3 Pack

They work great with my electric bike. They accidentally sent me 4 so I got a matching 48V hub motor that gets me to 33mph without pedaling! At top speed and no pedaling they give me a range of about 6 miles. Going slower and pedaling a little increases the milage a lot. Oh also they're super durable! Crashed my electric bike a couple times and these things flew all across the street and they didn't start leaking acid or anything! I also accidentally shorted my circuit across the 48V with an alligator clip and the thing sparked so much and got so hot it welded my clip to the battery, but after dremeling the metal off, the battery still worked fine! Just a word of caution they are super heavy though, and having them mounted above my back tire made my bike feel kinda sketchy and wobbly.

Batteries arrived quickly and worked as needed. I would order them again without question.

Razor is running much better and holds charge well.

I ordered this for my grandson's 10th birthday. The package arrived on time and he was so excited. My grandson lives out of state but his mom posted a picture of him riding his electric dirt bike in the backyard with his little brother what a smile on both of their faces7

Almost trashed the bike but now am glad I didn't!

Great batteries!

Who knows how good they are we'll see how long they last

Worked out great and packaged securely with cardboard paper
