160A Dual Battery Control Kit

Installation Instructions

Pre - Installation

 Disconnect both batteries by removing both the positive and negative terminals before

commencing installation. It is a safe practice to always disconnect negative first. You should

always check with the manufacturer before disconnecting batteries on late model vehicles.

 Ensure the Auxiliary Battery is mounted securely to prevent movement in any direction.

Location

 The Baintech Voltage Control Relay (VCR) should be mounted on a flat dry surface under the bonnet

such as a firewall.

 The Baintech VCR must be kept well away from hot items, such as exhaust systems or turbo

chargers.

Attaching Cables

Before cables can be attached to the batteries you will need to attach a lug to the end. Please follow the

instructions below for attaching Lugs.

1. Strip the plastic insulation off the end of the cable for approximately 15mm. Fit the appropriate

connector and crimp in place.

2. Slide some heat shrink sleeving over the connectors and heat with a heat source until secure.

3. Attach the lugs to the batteries as per the instructions for cable connection.

Cable Connection

1. Run the other end of the cable to the VCR preferably keeping the cable away from any moving parts

and cut to size.

2. Attach one end of the positive (red) cable to the positive terminal of the auxiliary battery.

3. Attach another section of red cable to the positive terminal of the start battery.

4. Attach both positive (red) cables to the VCR. The Cable attached to the start battery goes to M8 stud

labelled ‘A1’, and the cable connected to the auxiliary battery goes to the M8 stud labelled ‘A2’

5. Use a spade connector to attach one end of the small negative/earth (black) cable to the VCR

terminal labelled minus.

6. Connect the other end of the small negative/earth cable to the closest earth connection (usually the

mounting point of the VCR or on a clean paint free surface).

7. Attach one end of the large negative/earth (black) cable to the negative terminal of the auxiliary

battery.

8. Connect the other end to the closest earth connection usually the chassis of the motor vehicle,

engine block or alternator, or where possible to the negative terminal on the start battery.

For safety reasons please ensure to use DC fuses on the positive cables where possible.

Refer to the installation diagram in Figure 1.

Options

If you want to use the emergency Parallel feature or winch bypass, you can make a switched connection from

the terminal marked “status”, (starting Assist) to the positive terminal on the auxiliary battery.

 For safety please ensure to use DC fuses on the positive cables where possible.

 Refer to the installation diagram in figure 1
