    • Buena bateria

    • So far works great in kids Razor MX350
I really wish I took pictures during the process of switching out the batteries. It was def a pain in the butt but I did it. The hardest part was u screwing all the screws. THE BATTERY DOES NOT COME WITH THE WIRES. I didn’t realize I had to buy the wires to replace as well so I had to wait for that to come in after I took the whole battery compartment off. But half the work was done already for next time. The battery fit perfect and now my son’s Razor runs perfectly. I just finished the project tonight so I can’t say how long the battery lasts but the Razor was completely dead when I got this as a hand me down. I swapped out for a new battery and wires and now it runs. I thought the price was good but then realized I needed to buy the waited too but still for both, it wasn’t bad. Cheaper than a new Razor. My son is gonna be so happy when he sees it. ... show more

Revitalized an old Razr mx350. The kids love it! Had to unsolder the old battery connections and solder the new ones into place. Not too hard, had a grandson help me.

    • Good product for the money. You will need connectors.
Great product. I installed these in a few minutes. The connectors worked fine. The motorcycle is running great. I also paired this with a new motor which also helped a lot.

    • This product SUCKS!!
Horrible product. Install - had to change out the connectors. Not a bad thing if the product would hold a charge for more than 2 minutes! The install is difficult due to how the electric bike is made to replace and hold the batteries but to then add in that you have to change the connectors out to something else than what the manufacturer made and then it DOESN'T hold a charge - less than 1 star. Batteries worked great for first few days. Now I charge for couple hours and all we get is maybe two minutes of use. Longevity - think of the most worthless thing you can dream up - and then this batteries longevity is worst than that. Value - well if it only lasts 30 seconds after being charged. You be the Judge! ... show more
