Baintech Wireless Connect - Eliminate Difficult Wiring Through the Firewall

Baintech wireless EDM


Bainbridge Technologies launch all new radio frequency transmitter and receiver pair that minimises installation times by eliminating harnessing issues through firewalls and other hard to reach installation points.

The Baintech Wireless Connect uses a compact sender and receiver box to communicate wirelessly through radio frequency. Each RF pair has its own unique ID so there’s no risk of interference.

Compromising a vehicles firewall with harnessing can lead to complications such as water, dust, and noise ingress. Bainbridge Technologies have partnered with an Australian owned manufacturing company to bring this exciting product into the auto electrical market. Delivered as a complete solution, the Baintech Wireless Connect includes: 4-way switch panel, 6-way fuse block, and the radio frequency transmitter and receiver pair.

With a working range of up to 20 meters, the Baintech Wireless Connect is designed for a wide range of automotive applications, including: 4WDs, emergency vehicles, and boats. Engineered to be discreet, waterproof, and provide wireless connectivity to switch accessories.

Designed with safety in mind, the Baintech Wireless Connect can be connected to a canopy buzzer (audible safety alarm). By installing a canopy buzzer, the transmitter communicates wirelessly to the receiver when the key is turned in the ignition - activating an audible alarm to notify the driver that the door or canopy isn’t closed.

-Compact + lightweight
-Easy to mount
-4x switch channels
-Wireless - prevents compromising dust/water/noise seals of the firewall
-Waterproof (excludes additional connections)
-Each pair has unique ID so there’s no risk of interference
-Can be doubled to provide 8x channels (by paralleling 2x pairs)

DC DC System

Build an off-grid system

Plug and Play for off-grid power with the Baintech PowerTop. The PowerTop is Ideal for people who want a portable power system, that they can locate near their campsite, lend to a mate or take out of their 4WD when home (to charge up and store away). To add solar, simply connect your un-regulated solar panel directly into the RED Anderson plug of the PowerTop. Our 120w Baintech Solar Blanket will provide up to 6.6A in optimal conditions.

If you’re planning an adventure that will take you off-grid for a weekend or more, a DC-DC charging system can ensure you have reliable power right through to the end of your travels. While on the move, wire your DC-DC charger into the GREY Anderson plug of the PowerTop and charge the PowerTop like you would your second battery. Completely portable and versatile, create the ultimate off-grid solution by pairing the PowerTop with solar and the new 40A DC-DC charger.

Installation: for best performance, we recommend installing your DC-DC charger in a well-ventilated area that won’t be submerged in water.

For all enquiries email: or call 1300 224 683

 Smart Alternator Baintech PowerTop (OLD MODEL CTEK DUAL)

Powertop Installation Wiring Diagram On Smart Alternator

How do I connect my CTEKD250SA/Dual to the PowerTop?
The electronics in the blue socket are different and the CTEK 250SA needs to connect straight across the internal battery which is
accessed through the Grey socket.

If you have an external DC-DC charger they must meet the following requirements:

• 20A maximum charge current

• Bulk 14.2V

• Float 13.7V

If the DC-DC charger meets these requirements connect the device to the Grey Anderson connector labelled 50A Battery Output.

Standard Alternator Baintech PowerTop

If you want to charge the PowerTop from the vehicle alternator, connect a cable to the starter battery, connect the other end of the cable to the Blue Anderson Plug on the PowerTop labelled Vehicle charge input. Fuse the cable at the start battery end of the cable. The vehicle voltage must be above 13.2V to charge the PowerTop battery. Recommended fuse size is 35 AMPS max.

Tricolour Anderson Plugs

PT3 side diagram

The Baintech Anderson plug is designed to lock securely together and provide a solid connection between two cables. Rated for 50A. The Baintech PowerTop has three colour coded Anderson plugs on the side of the unit. These plugs can be used to connect to external charging inputs or loads. Each colour is keyed differently to ensure correct connection of loads and charging inputs.

RED ANDERSON: Solar/External
Accepts charging from UNREGULATED solar

BLUE ANDERSON: Vehicle charging input connection

GREY ANDERSON: Load connection to and from battery - Accepts charging
from a REGULATED solar power source only
• Accepts regulated solar only
• Protected by a 50A thermal self-resettable breaker
• Can be used for 12volt input and output power source in applications e.g: Inverter, DC-DC charger (from smart alternator),
high current AC-DC charger, or a regulated solar power source to charge the PowerTop
