Dual Battery Systems

The first step in choosing a suitable battery management system is to clearly identify the electrical equipment you intend to fit to your vehicle. Electric winches, fridges, auxiliary driving lights, communication equipment, etc. all have different requirements and they can flatten a battery very quickly without the appropriate dual battery management system installed.
The next step is to choose which of the TJM DBS and IBS management systems will satisfy your needs. Both of these user-and-fitter-friendly battery management systems offer the following features:
• Automatic systems that link batteries for charging and isolate batteries for discharging. • Easy installation - no alterations to vehicles wiring. • The ability to use "Start" & "Deep Cycle" Batteries together. • Monitoring voltage of both "Start" & "Auxiliary" batteries. • Priority charging to the "Start" battery. • Spike voltage protection to EFI and automotive computer systems. • The ability to be installed to an extensive range of vehicles with varying alternator output. • 5 Year Australian Wide Warranty.

Modern computerised vehicles require state-of-the-art dual battery management systems that automatically monitor the voltage and isolate spikes to ensure adequate protection of the electrical systems.
Both the DBS and IBS Battery Management Systems supplied by TJM offer this protection.
So Which is the correct battery to use?
There are basically two types of batteries suitable for dual battery systems:
STARTER BATTERIES:
Designed for high current discharge but adequately cater for most situations. Recommended for starting vehicles and winching operations.
DEEP CYCLE BATTERIES:
Designed for low current discharge over a long time. These batteries should not be used as starter batteries but are recommended for running refrigerators, camping lights, air compressors, etc.
DUAL BATTERY SYSTEMS REQUIRE THE FOLLOWING:
• A quality battery management system. • A battery mounting frame. • An appropriate battery. • A power outlet.
