Worthy addition but may not fit your case.

I'm not getting any use out of mine but it's not to be blamed on the RTC shield or the C2 boards. This item does exactly what it is meant to do and fits on your C2 perfectly. Unfortunately this shield does not fit in either the Cogent Design or Wicked Aluminum cases for the C2. Every C2 SBC I own is inside one or the other above mentioned aluminum cases. Neither maker thought to make room for the battery shield in the case. I'd like to use it but I'm left with a choice of having the battery or having my boards in aluminum heat-sink cases. Given my options I leave the battery shield off. There isn't a very wide choice for aluminum heat-sink cases for the C2 to be found. It's a shame the battery shield won't fit inside the ones I have.

Thanks for your review, Billy! We aren't familiar with the exact size of the cases you mentioned, but would it be possible to move the RTC Shield to another location inside the case using M-F breadboard wires? Something like this: https://ameridroid.com/products/male-female-jumper-wires-40-pcs-x-8in
