In my recent review of the 28mm Spanish Fort I already mentioned that I also got the battery piece that was funded via the kickstarter project. The battery is a solid piece of resin. Aside from the main piece there is a planking piece, similar to the one that was provided with the Spanish Fort, and an MDF kit for a ladder - again, same as with the fort. So, beside filing off a few sharp edges and assembling the ladder, there is no further assembly required.
