OK here is the battery shield. Note the dimensions were taken from a jpg image so are likely not all that accurate (mostly important in pcb!) If you have a board, print out the pcb footprint at 1:1 scale and compare it to the board (and provide corrections if it is wrong!) As well the mounting holes are by default not drilled in pcb, if you want mounting holes you need to drag a hole (from core partsépcb) in to the sketch and place it over the circle in silkscreen and set the appropriate size.

I`ll do the other one in a while.
