4 AAs?

by Freedy500 on Sun Sep 15, 2013 2:16 pm

Just want to make sure I could hook up for double AAs at 2500 mah and (after fresh charge at least) at 1.4-1.5 volts (give or take a few tenths). I ordered two minty kits but only needed one. So instead of using both AA holders you guys sent me I thought I could use one that holds 4 AAs instead so I could save room and keep the female USB port from extruding from the altoids case.

Now I'm outputting 5.61 volts with my rechargeable AA energizer batteries.

Just don't want to screw this up.

If you are using alkalines, use no more than 3. If you use rechargeables (e.g. Eneloop), you can use 4. http://learn.adafruit.com/minty-boost/batteries

okay so im using rechargebles. and even though im at 5.6 volts from the battery pack just sitting still (not connected to board yet) it will be safe for me to use? again, im using 4 rechargeable batteries outputting a combined voltage of 5.6 i will still be able to solder it to the board.

If they are AA NiMH cells, the output will drop pretty quickly under load to ~1.2v per cell. These should not be a problem.
