These are the parts required to fully populate the battery board. You may not need all of these parts. This list only concerns the battery board itself. If you will be placing the battery board in a separate case, you'll need parts not given here.
I don't give part numbers for resistors because resistors are more or less generic. I recommend 1% metal film types for most of the resistors on the board. See the schematic and the Part Selection Guide for recommended resistor values and types.
Some components are marked "Alt.". These are alternatives for the immediately preceding component.
