With the new e tube wiring you can mount the battery anywhere you want and could even put it in the handle bar in most bars and just plug it into a port on the A junction box , really up to ones imagination however the seat post works just fine. In the builds I have been doing I have just been wrapping the battery in packing foam and pushed them into the seat post with a zip tie sticking out to remove it by and they stay just fine light and free.For the latter I suppose a bunch of foam wrap would work as a holder. BTW I carry one long spare wire when traveling that I could replace any wire on the bike with if one were to get damaged.
