BI Battery Isolators
Mastervolt’s BI battery isolators
are based on conventional
diode technology. The diode
voltage drop (ca. 0.6 V) can
be compensated for by
adapting the output voltage
of the connected charger
or alternator. Mastervolt
battery chargers and Alpha
Pro MB charge regulators
come as standard with
automatic compensation
for voltage drops.

Battery Isolators
Battery Mate
While battery isolators are conventional diode
splitters, the Battery Mate’s technology is
electronic and includes mosfets (transistors).
Its components compensate for the voltage
drop and ensure that charging continues at the
right voltage level, even with several battery
banks. The Battery Mate is compatible with any
type of alternator/battery charger, in both
existing and new systems. As the voltage loss
between the alternator and battery is negligible,
the Battery Mate performs far better than
conventional battery isolators. This ensures fast
and complete charging of your batteries
without having to make additional adjustments
to the alternator.

Battery Watch
The Battery Watch is an essential element of any well-equipped battery
system, offering you a 1.3 lbs electronic watchdog that ensures a much
longer lifespan for your batteries. The unit switches off loads when
batteries are nearly empty, to keep your batteries in optimum condition.
LED lights provide a clear read out and the undervoltage can be set
using DIP switches.
