FACTS
Why does one Intelliswitch mA meter show a different consump-
tion value to the other?
Batteries have an internal resistance. Think of this as a force at
-
tempting to stop current from flowing out of the battery. Not all
batteries have the same internal resistance. A battery with a lower
internal resistance will offer its power more readily. Intelliswitch
has two completely independent switching and metering circuits.
Each circuit switches and meters one battery. The combination of
battery internal resistance, connector and extension lead resis
-
tance may show as a higher mA usage from one battery when
compared to another. The aim of metering battery capacity with
your Intelliswitch is to get to know the characteristics of your bat
-
teries so you can monitor the health of your battery packs.
Connecting the outputs of Intelliswitch together
.
This will work fine in a single receiver/Cybuss system (as long as
the batteries are the same chemistry and cell count). The battery
with the highest voltage will supply the load to the receiver/servos
and try to balance the 2 batteries. Think of 2 buckets of water,
each bucket filled slightly differently. If you connect the 2 buckets
with a hose then the bucket with higher water level will try to fill
the bucket with the lower water level until they are equal. It is
the same with batteries and this is why we should always use the
same battery type and cell count when connecting the outputs of
Intelliswitch together.
