I'm almost done building my 30A Standard Charge Station Combo (no longer available I think), which includes an RGB display. On the display board, there is no slot for a backup battery. Is there any other way of hooking up a battery, or even rechargeable batteries?
Hi Sander, The battery is CR1216, CR1220 or CR1225. We do not ship with a battery for a couple reasons... The battery is optional and only required if you use charging station based timers and you wish to keep time after a power failure. We are looking at using WiFi to set the clock and introduce more advanced features such as automatic DST adjustment so it may not be needed at all for WiFi equipped charging stations very soon.
Additional shipping lithium batteries including small coin cells introduce many restrictions that varies from carrier to carrier country to country. Not sending the battery makes shipping much easier.
The Standard kit includes a Monochrome display and no real time clock. Without a clock there is no need for a battery.
The Deluxe kit adds Color Reg - Green - Blue Display, Real Time Clock, Temperature sensor, and Current measurement coil.
Hmm, normally on the RGB display backpack there is a little battery bracket for a CR1220 battery. You say it is not mounted on your PCB? Can you post a picture if it is no trouble for you.
If I were you I'd order this little breakout board and solder a few wires for the + and -. I just think it is easier to solder than the metal battery bracket itself.
Maybe Chris will read this. I suppose the battery bracket may have been omitted from the RGB LCD by some mistake. Also maybe you have the MONO LCD that does not have the DS3231 RTC chip and in that case there is no purpose for the battery and it is normal to have the bracket not mounted. That is why posting a picture can helps us figure out how best to move forward.
