KingSong KS-18L inner shell reinforcement

This is an essential precautionary measure to prevent further damage. Installing it afterwards would be pointless if the shell has already been compromised. I had to replace both batteries because their mounting points were cracked, so I fabricated new ones (bat-h). Note that you should grind them down slightly when installing them on top to ensure a proper fit, otherwise the side body shell won't align correctly. Adding a couple of washers underneath will also help reduce stress on the battery box. The material used for this repair is ABS plastic. To secure it properly, use an appropriate adhesive or ABS slurry.
