Talking things through
I just want to check here with y'all to make sure I'm not making a mistake.
I have a Honeywell Vista 21ip, a 4219 expansion board, a 4229 expansion board, a 5881ENM wireless receiver, a 6160 keypad and a 6280i touchscreen keypad (all self-installed).
I would like to install two additional 6280i units, but since I'm knocking on the 600 mA max limit for the system board, I need to install an AD12612 auxiliary board. Plus another 1361 transformer and another NP4-12 battery.
Can I swap out the current NP4-12 battery for an NPG18-12 battery and have it connected to the system board AND AD12612 auxiliary board, instead of having two batteries?
I know I'll still need another 1361 transformer for the AD12612 auxiliary board. And I'll probably offload the current 6280i keypad to the AD12612 auxiliary board when I add the two new 6280i keypads.
Am I missing anything or on the right track? Thank you in advance!

Well, that answers that. I guess I need to budget another $50+/- for a second battery.
Thank you Mr. Ron!

I use a lot of aux power supplies in the systems I install. Usually a 12v7A is plenty for aux power. They can be found from $20-25.
