IDEAL 
BATTERY ISOLATOR
MODEL
IBI2 & IBI3 Series
Description
Analytic Systems introduces the IBI (Ideal Battery Isolator) for 2 bank 
and 3 bank battery systems, allowing all the batteries to be fully 
charged from a single alternator while maintaining electrical isolation 
between the battery banks. 
Ideal Diode technology uses MosFet Transistors and control circuitry 
to replace the diode used in a traditional battery isolator and reduces 
the voltage drop across the isolator to a mere 160 millivolts at 200 
Amps of charging current and essentially zero volts at low current, so 
all the power of the alternator is applied to the batteries ensuring a full 
recharge every time. 
While the Ideal Battery Isolator is designed to be used with an 
alternator, it can also be used to convert a single bank battery charger 
to a 2 or 3 bank charger.
Benets
•  All batteries charge when engine running, regardless of master 
switch setting
•  Batteries isolated from each other when engine off
•  Complete battery charging due to very low voltage drop, only 0.16 
volts at 200 amps and 0.016 volts at 20 amps
•  200 Amp current carrying capacity ensures compatibility with 
almost every alternator
Design Features
•  All circuitry sealed in epoxy for water resistance
•  The alternator can be directly wired to the batteries through the isolator
•  CNC machined connection points and bronze fasteners ensure low 
resistance connections
•  Internal high current busbar for optimal current distribution
•  Compatible with 12, 24, 28 and 32 volt battery systems
•  Can also be used with a single output battery charger
•  Extremely compact design saves space
Available in three colours
