Designed for use in dual battery systems eg. a main battery and an auxiliary battery. The auxiliary battery can be connected to a load, such as a camping fridge, while the main battery is isolated and not subject to any current draw. This allows you to start your vehicle using the main battery if the auxiliary battery is flattened by the load. Automatically connects the auxiliary battery for charging once the main battery reaches the selected cut in voltage and disconnects it from charging when the main battery falls below the selected cut off voltage.
May also be used with a single battery, operating as a low voltage cutout to prevent over discharge.

  • Can this item E2104, be used in 2007 Toyota Prado diesel. As the Prado ECU sets the battery charge against the load being drawn, I envisage connecting 2 batteries in parallel using this unit. The auxiliary load would still be connected to a spare output from the ECU. Therefore the ECU would still set the charge rate. Your advice appreciated.

    Hi, thanks for your enquiry. I would suggest you need to check with Toyota re the ECU. Or perhaps an auto electrician could advise.
