Hi all,

```
    I have a question about how to energize the Digital and Analog adapters (XBee Digital IO Adapter, XBee Analog IO Adapter), in the documentation said that you can use battery with voltage between 3,7 and 6 V, but in the adapters you have two slots for battery.

```

If you have the 3-6v model, which has what looks like 2 slots (4 tabs of different size), then you need to use a special lithium battery build for that product. It is part XA-ACC-CS-L. This somewhat funky looking battery-pack has 2 different sized batteries linked togather, which insures you cannot install it backwards (I guess 🙂

Or you can use any external battery pack which totals between the same 3.7 to 6 volts.
