There’s not a lot of room in the XB2 to squeeze everything in. Even if you wedge all the electronics to the front, you’re left with some not-so-great battery options. You can use foam to move it around or you can add some posts to shove it all the way back.
And while you can appreciate Xray’s complicated solution with like 45 pieces for its effectiveness, there’s probably something a little simpler. Each kit comes with the rail holders, mounting hardware and tabs. Just tighten the lock nuts down over the tabs and keep your battery where it belongs. Whether that is all the way to the front, all the way to the back, or anywhere in between.
You can even mix your colors for an extra custom look.
