Worth considering.

Pleased at the quality and that it seems to actually be 30 Ah. There is a short learning curve to understand and properly use lithium batteries. So far this one has made that easy. The few pages in the user manual are helpful and make sense when more precise info is learned from additional sources available online. I like the light weight but strong build of this battery and the easy to use handle. With the offered warranty it is easy to like this company. I am planning to use this as a replacement battery for a "GZ" power generator.
