They also help to overcome voltage drop, particularly over long cable distances, such as to a camper or caravan. It not only ensures correct charging, but also overcomes some of the low outputs by modern vehicle alternators that are not suitable for charging dual batteries. The added solar input lessens the load on vehicle alternators and provides a “greener” power solution.Ī BCDC offers greater flexibility for your dual battery system. With their state of the art technology, many of the REDARC BCDC chargers also support simultaneous charging from both the alternator and solar panels or solar blankets. Whereas a smart battery isolator will only top up the second battery as it is primarily focused on the state of charge of the primary battery. They use a multi-stage charging profile to ensure your secondary battery is charged to 100%. They are suitable for 4x4s, caravans, trailers, boats and heavy industrial vehicles.Ĭomplete manuals and wiring diagrams are also provided for an easy install experience.Ī REDARC BCDC battery charger helps to ensure your auxiliary battery stays charged no matter its type or size. Here at AutoElecOz we stock the full range of DC DC chargers with every combination of input voltage, output voltage and current specifications to suit your vehicle’s needs. When it comes to managing in-vehicle dual battery systems, you can’t go past a REDARC DC to DC charger and their range of REDARC battery isolators. REDARC TOTAL VEHICLE MANAGEMENT SYSTEMS.A few models - such as the Ja圜orp Dual and KeyLine Smart - are designed with advanced technology that enables them to monitor the voltage of each battery individually to prioritize which requires focus for charging. While the Zoostliss Power isn’t constructed to handle a ton of current, reports indicate that it’s an ideal choice for light duty that provides remarkable value. As we included it on our list, we obviously think it’s a model well worth considering, but it should be noted that it offers no water resistance or accommodation for inrush current from motor loads, and its design also looks like it might not lend itself to as many installation options as some others.įor users looking for ways to help make sure their single-battery systems stay in ship shape, our rankings for solar battery maintainers may be of interest to you. We added the NewishTool Switch Charge to our list, and it first caught our eye with its sleek, metallic housing, but what really held our attention was its integrated voltmeter, which takes simultaneous readings from both your batteries and displays them side by side on its simple LCD. That being said, the utility they offer is nothing close to some of the smart options higher up on our list, so please don’t think that we’re suggesting a disconnect as an apples-to-apples alternative to an isolator. However, we decided that these picks were still worth including at the bottom of our list, for the benefit of users on a budget who don’t mind using devices like these to manually disconnect their secondary batteries when they’re not in use. We also put some serious thought into axing the Zoostliss Cut Off and Audew Disconnect Switch, as neither of these options are actually isolators, with both essentially being simple kill switches. We spent a while digging through our existing choices, and eventually determined that most of them were still good picks for the category, but we did end up doing away with the Install Bay 5841730504, noting that it closely resembled some of our other relay-based choices, and noticing that it’s no longer listed on the company’s website - which led us to wonder whether this model might be facing discontinuation.
