hot feed Information on New Products from Cole Hersee Company NEW Smart Battery Isolator Prevents loads on auxiliary battery from draining the starting battery More flexible than traditional Isolators: Works with all alternator types Smaller, lighter, less heat generated No diode efficiency losses Reduces charging system workload by not connecting auxiliary battery until primary battery is charged to 13.2V. Lower strain on expensive charging components extends their useful life. Allows bi-directional charging from alternator or from shore/campground power charger/converter when available. Simple installation - Connect to starting battery, auxiliary battery, and ground. LED status indicator. Cole Hersee part numbers 48525 48530 85A 200A Optional Start Assist – Momentary switch allows the auxiliary battery to assist the starting battery.

This protects the starting battery while allowing NO3 battery to continue to power the auxiliary loads. the auxiliary + 12.7 V Auxiliary battery 3 When batteries reach 12.7V, the Smart Battery Isolator senses it, - 13.2 V 4 Auxiliary battery When the vehicle is restarted, the starting battery has enough power to crank the engine, but the auxiliary battery is significantly depleted. The Smart Battery Isolator is open and the battery banks are separated. NO4 Status Light Status light is off and Smart Battery Isolator is open Alternator Alternator + - 13.2 V - House/ Auxiliary Loads 12.7 V Starter Main battery + + has reached 13.2V. Only now does the Smart Battery Isolator reconnect, enabling the depleted auxiliary battery to be charged. By not reconnecting until the main battery is charged, the NO5 alternator is protected from excessive loads. 13.2 V - House/ Auxiliary Loads Starter 6 Main battery Auxiliary battery Now both batteries are charged again.

After one minute the Smart Battery Isolator reverts to the automatic mode. If the starting battery has not reached 13.2V, it isolates the batteries to reduce stress on the alternator. Once the main battery reaches 13.2V, it reconnects and charges the auxiliary battery.
