Newmar Bi-100 12V Battery Integrator, BI-100
Use of multiple
battery banks dictates that the batteries be connected or "integrated"
only whenever a charge voltage is present so that they may be charged
simultaneously, then disconnected or "isolated" when in use to allow for
selective discharge and avoid having the secondary or standby battery
drain into the primary battery.
new Battery Integrator performs this function automatically, acting as a
"smart" switch to connect independent battery banks only when a charging
voltage is present. Otherwise, they are isolated, and discharge between
banks is prevented.
traditional rugged and reliable diode isolator can also be used for this
Battery Isolators), as it also maintains isolation between banks and
allows charging from multiple sources. However, one drawback is
inefficiency when voltage is lost as current passes through the diodes,
resulting in undercharge if the charging source does not compensate for
the voltage drop.
Battery Integrator remedies this by use of an extremely low resistance
contactor which causes no voltage drop in the charging system, while the
multiple batteries are charged as a single bank whenever a charging
source of approximately 13.2 VDC or 26.4 VDC or greater is present
(depending on model).
When the alternator or
charger is off or a large load causes the voltage to drop below the
disconnect point the unit breaks the common tie between the banks. This
allows selective battery discharge and prevents "dumping" of a
higher-charged bank into a lower-charged bank.
The unit may also be
activated through the key starter or a manual switch to provide an added
"boost" from the secondary battery whenever the starter is engaged and the
unit senses there is sufficient voltage in that battery to provide an
For systems with more
than two banks, an additional unit may be installed for each additional bank
to provide the same isolation and integration as described above.
Integrator is ideal for multiplying the single charging output of an
inverter-charger to maintain both the house bank and an engine start
bank, then to isolate them during inverter function, so current is drawn
from the house bank only.

two separate banks without voltage drop, yet maintains 100% isolation at
all other times. For systems of three banks or more, an additional unit
may be installed for each additional bank
