2 Electrical Specification
The Battman module is a single or dual Smart Battery Manager. The module supports a
standard 2.5 mm DC Input Jack for connection of a standard 19V AC/DC power adapter. The
battery charger output voltage is configurable to adapt it to battery packs consisting of 2, 3,
4 or 5 Li-ion battery cells*. The module can work in either notebook mode (ACPI) or as
stand-alone battery charger.
* Battery packs with 2 or 3 cells cannot provide 12V output and will not support the
requirements of COM Express systems.

2.3 Functional Characteristics
f Dual Charging - charges two Smart Batteries simultaneously to reduce charging time
f Simultaneous Discharge - simultaneous dual discharge increases battery operating
time by reducing internal battery losses due to high discharge rates
