Due to this highly variable voltage VSRs are not suitable for use with 'smart' alternators.īattery-to-battery chargers are simple to install and will engage/disengage automatically on engine start/stop, ensuring the batteries are isolated and cannot discharge one another. ![]() These have a highly variable voltage output that is often too low to provide a charge or (in the case of regenerative braking systems) so high that it can damage some battery types. Using a battery-to-battery charger is the only reliable solution if you intend to re-charge a second battery in a modern vehicle that has an ECU-controlled 'smart' alternator (generally Euro 5/6 compliant engines onward). This provides a 100% re-charge for your leisure battery in a controlled way and typically achieves it faster than with direct alternator charging. VSRs simply allow charge to pass directly from the alternator to the auxiliary battery whereas Battery-To-Battery chargers take the alternator output and boost or reduce it to provide a stable voltage output according to a multi-stage charging profile. In a traditional split charge system with a VSR will only achieve around an 80% charge state. ![]() RV battery isolators may work well on RVs with wheels but their use on RVs with wings. They are installed in-line between the positive terminals of two batteries (one of which is connected to an alternator, typically a starter battery) and offer several benefits when compared with traditional split charge systems that utilise a Voltage Sensitive Relays. Manual auxiliary battery control is possible: simply eliminate the. Battery to Battery ( DC to DC ) Split Charging with Wiring Diagramīattery-To-Battery chargers (also commonly known as DC-DC chargers) allow you to charge a leisure battery from your alternator whilst driving.
