The VSR 6mm charge kit  has been designed with a VSR dual battery isolator to charge batteries either in the rear of the vehicle or in the Caravan or Camper Trailer.

The Charging kit comprises of a 140 Amp Narva voltage sensitive dual battery isolator. This isolator will allow for the vehicle's main battery to reach a full charge of 13.3 Volts then will automatically switch the charge to the secondary battery. This isolator takes priority over charging the vehicle's main battery to ensure the main battery reaches and remains at 100% capacity.

The kit is supplied with a heavy duty 8mm automotive connecting cable with in line automatic reset circuit breaker - rated to 50 Amps.
This lead comprises of a 250mm length to connect circuit breaker to isolator and another 600mm length to connect Main battery to VSR.

The final component of the charging system is a 6mt continuous length of 8mm twin core (automotive) oxygen free cable with a 50 Amp Anderson connector.
This lead is designed to run from the VSR (located under the bonnet of the vehicle near main battery's location) to either the rear of the vehicle (inside location) or to the towbar to continue to the Caravan or camper trailer to charge your secondary battery(s) system. (optional extra kit is available for the wiring of the caravan / camper trailer)

Narva VSR140 Amp Isolator

Narva’s new Voltage Sensitive Relays have been specifically designed for a wide variety of 12V & 24V applications.
The VSR units sense the input voltage generated and automatically connect / disconnect the appliance or circuit at pre-set voltages, eliminating the possibility of discharging the primary starting battery.

Constructed with a weatherproof body (IP65) and durable silver tipped contacts, the VSR units also feature surge protection and a L.E.D indicator designed to alert the user when the unit is engaged.

Narva’s VSR units are ideal for dual battery set-ups as they enable two batteries to be charged at the same time and then isolates the batteries from each other when the vehicle is turned off, ensuring your starting battery is always charged & ready to go.
