INPUT POWER – CONNECTION, PROTECTIONS & LIMITATIONS
The meter draws input power
from the battery that is
connected for measurement.
The meter will automatically
enter a sleep mode if no
commands are given within
30 seconds, but note that
power will still remain active
in the meter during this time.
Simply press ENTER to re-
activate the meter.
The BATTERY lead on the
left side of the meter is used
for connecting large power
batteries. Lithium packs up to
7S can be used, including LiPo
batteries rated at 25.9V, LiFe
packs up to 23.1V, and Li-Ion
packs up to 25.2V.
The RX/TX battery jack
can accept NiCd and NiMH
batteries having a nominal rating of up to 9.6V, with a universal or
Futaba
® J type connector.
The PowerMatch meter can handle up to 80 amps of current
instantaneously, and measure capacity up to 65Ah (65,000mAh).
Passing more than 50 amps through the meter continuously for
over 2 minutes will cause heat to generate and cause readings to
become less accurate. Do not exceed the maximum rated current or
voltage handling capabilities of the meter.
