200 Amp Smart Battery Isolator
THOR Battery Isolators
THOR battery Isolators can be used as a battery or circuit isolator to allow your alternator to
charge more than one battery but keep your starting battery from being drained when the
vehicle is not running.

*Optional Start Assist – Momentary switch allows the auxiliary battery to assist the starting battery.
THI Series battery isolators can be used to isolate circuits or batteries .These Battery
Isolators are simple to install, take up less room, and are more durable than standard
battery isolators. They require less then 1 amp to operate. Take your pick of either our
80 amp, 200 amp or 500 amp model.
THI-500
500Amp Continuous at 12Vdc
THAI Series electrically isolate the batteries to prevent the battery with the higher
charge from draining into the secondary battery with the lower charge. This reduces
the load on the charging system by not connecting the auxiliary battery until the
primary battery is charged to 13.2V. The isolator connects the two batteries together
when either battery voltage is above 13.2V for 2 minutes (e.g. during charging). The
two batteries are isolated when both battery voltages are below 12.7V for 1 minute.
The BOOST function connects the two batteries to provide more starting energy. The
STATUS indicator and the on-board LED are turned on when the two batteries are
connected together.
