Redarc SBI12D Smart Start Dual Sensing Dual Battery Isolator 12V 100A
The Redarc Smart Start SBI12D is a dual sensing microprocessor-controlled battery isolator for 12 V dual battery systems, rated at 100 A. It protects the starting battery from over-discharge and, thanks to dual sensing, also connects when the auxiliary battery is the one being charged.
The ideal solution for motorhomes, caravans, 4x4s and boats with a solar panel or mains battery charger connected to the auxiliary battery: surplus energy is shared with the starting battery too. Designed and manufactured in Australia.
Key features
Bi-directional sensingConnects when either battery reaches 13.2 V, so solar or a mains charger also tops up the starting battery.
Start battery protectionDisconnects at 12.7 V to always keep enough cranking capacity.
Silver alloy contactsLonger life and suitable for marine use.
Compact overmoulded housingEasy to install and resistant to vibration and moisture.
Low power draw and diagnosticsStandby below 5 mA, fault indication and full surge protection.
