Electronic Isolators
Electronic isolators ensure that the main starting battery is charged before connecting the auxiliary battery. It does this by monitoring the voltage in the main battery. When the voltage in the main battery reaches a predetermined threshold, the isolator switches to charge the auxiliary battery. It will also disconnect the auxiliary battery from charging if the main battery voltage drops below that of another predetermined threshold. Thus this system ensures that the main starting battery is always given charge priority and therefore the risk of having a flat main battery is greatly reduced.Piranha Electronic Isolators have another huge advantage; they can be fitted to any vehicle - diesel, turbo diesel, petrol carby or EFI with internally or externally sensed voltage, it doesn't matter, it will work exactly the same on all types of vehicles.
In the mid 1980's Piranha introduced the first Electronic Isolator (the DBE 100S now obsolete) that revolutionised the way Dual Battery systems worked. Electronic Battery Management Systems now work on the same basic principals as this revolutionary product.
