Sorry, I meant I can't use columns of LEDs as initially planned.

I'm switching for the 100mA LCDs that I have on hand. The house has only 1 keypad, the garage will have 2. That means I can live with 1.5A, even only 1A if I must.

So now I'm looking for improvements on the latest schematic, and a battery-charging circuit is a bonus.
