There are extra-long seat posts for sale. You might find what size fits your frame by removing your current post. The width, in mm, is often stamped into the lower end of the post.

Another option is to mount the battery base on the top of your frame's top-tube. It seems like it has some water-bottle mounts up there. The stress on an extra-long seat post is significant. Adding a heavy battery to that seat post is worse. You could use a Grin Triple-Bob mount to make it even stronger.

Don't know about battery mounting, but that frame scares me. Are you heavy? Ride fast? Rough terrain? It's unsuitable for any of the above.
