1.2.2 Battery Pack (not available for SXblue 12/24 volts)
The Lithium-Ion battery pack
attaches to the receiver with
four thumb screws. Modular
contacts are used to supply
power to the receiver. Even
though the Li-Ion battery
pack has a built-in protection
circuitry, care must be taken
not to short the contacts on
the battery pack.
Also, membrane vents are
used on both the receiver
and battery pack. These
small holes should not be
punctured, obstructed or
covered by labels or stickers.
The battery pack features an
intelligent
battery “fuel
gauge” that shows the level
of charge (see Figure 1-1).
On initial usage, it might take one or two charge/discharge cycles for the gauge to
reflect the proper charge level. When unit is not used for an extended period of
time, it is normal that the battery pack discharges. The field autonomy of the pack
is roughly 9.5 to 15 hours depending on the model and after 500 cycles, battery
capacity starts decreasing to about 80%.
Since the SXblue receiver (except SXblue 12/24 volts) use Li-Ion battery
chemistry, there is no memory effect as for NiMH or NiCad batteries; therefore it is
not necessary to discharge the pack before recharging it.
Only proper Li-Ion
battery charger must be used with the SXblue battery . Using any other type of
charger might result in explosion and injuries. The SXblue battery pack
specification is: 2s2p, 7.2V, 3,900mAh Li-Ion. If using a different charger than the
supplied charger, the following specifications must be followed: 2-cell Li-Ion
charger, maximum current of 2A, charger plug to fit a 1.7mm positive center-pin
jack with 5mm OD.
Charge time with supplied charger is about 4 to 5 hours when battery is empty.
The charger is equipped with a charge indicator LED that will switch to a steady
Green when battery is fully charged. The charger supports input voltages of up to
240VAC.
Warning – Use only supplied charger with the SXblue battery pack.
Do not disassemble, modify, puncture, mutilate or incinerate or heat battery
pack.
