Yea that was a oversight on my part, as for the PCBs for low battery what got shipped was some other boards I also ordered as there was an issue with some parts for the assembly and they contacted me through Skype and I of course wasn't home to reply so the PCBs have been delayed and will likely not arrive till next week.
So anyone wanting to combine shipping on those boards with the kit will have to wait till next week for me to ship things out.
