12V 140A Voltage Isolator Split Charge VSR Voltage Sensitive Relay Dual Battery

Specifications：
High Quality 12V 140A Split Charge VSR.
The Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time. 
When the engine is started and the start battery reaches 13.3 volts, the VSR engages, allowing two battery banks (start and house) to be charged simultaneously.
When the voltage drops below 12.8 volts (eg the engine is stopped), the VSR disengages, separating the batteries. 
This system eliminates the possibility of draining the start battery and protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes.
 
Features:
Voltage sensitive relay12 volt 140 ampRed LED indicator.
Allows split charging of the 2nd battery bank without discharging the primary/start battery.
The relay makes at 13.3 volts and breaks at 12.8 volt.
Advantages of fitting a VSR over conventional charge (diode isolators). 
Easy 3 wire connection at the battery. 
No need to bypass existing alternator wiring. VSR have no volt drop. 
Conventional diode isolators incur a minimum of 0.6 volt drop.
