I got my son an electric dirt bike for Christmas and found out the battery wouldn’t hold a charge. It was easy to find a replacement for it here. Quick shipping and very well packaged. Quick to install and now the bike runs like new

It is the correct dimensions and easy to swap. It charges, it holds a charge, and is worth the money.
