Hi,
I saw another post about this by someone else and I have the same question. I received my VEXNet Upgrade Kit in July and it arrived without the 9v Backup Battery Holder and cable. I emailed Tom and he said that they would be sent out when they were in stock.
I hadn’t received it yet and the website still doesn’t say that they are in stock yet. It has been a few months and I just thought that I would check again.
Thanks,
P.S. The VEXNet Upgrade works great!
