This past weekend I jacked the #1 truck up to determine if I could get another water tight connector mounted into the front of the battery box. It looks like my only option is to remove the 1/2″ connector that is there for the Emeter cable and install a larger one. This would still be a tight fit to install. I may consider just adding lithium to the #2 truck, but it does not have a good pack in it yet. I have seen other trucks with a hole drilled and filled with silicone. Not an appealing solution.
