Excellent delivery. Installs easily. I didn't see much improvement in the state of charge with the digital gauge showing the state of charge, but did notice a nice improvement in battery performance at this level (it seems to last longer at this level). It would be nice to know that for best performance it is recommended to install one battery per cell/cell group rather than one 36V battery per battery. In general, getting another would be easy, especially in the same circumstances. given the price.
