![]() 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).Current flow is limited by the charger's current rating, eliminating potentially damaging high in-rush currents and often allowing the use of smaller connecting cable than with VSR-based split charge systems. ![]() 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. Direct alternator charging used in a traditional split charge system with a VSR will only achieve around an 80% charge state.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 Relay (VSR) or heavy-duty, alternator-triggered relay. The input cord is about 2 feet in length and is detachable.Īpproximate weight and dimensions for the 3000W max version: 17 lbs.Battery-To-Battery chargers (also commonly know as DC-DC chargers) allow you to charge an auxiliary / leisure battery from your alternator whilst driving. Since EV chargers output voltages may vary a little from one to the next (usually between 200-250V), this converter also features a multiple input voltage selection, enabling you to tweak the output voltage when desired, to maximize your available power. We have carefully inspected it and determined that the damage is only cosmetic and has no effect on its operation, safety, or reliability. The cosmetically damaged product was damaged in shipment to us - specifically, there may be some small dents to the bottom, sides, or corners of the transformer. Note: We offer your choice of a new product or one with cosmetic damage. The input cord is 2 feet in length and plugs into the back of the unit - it is detachable for ease in installation. ![]() Continuous rating is 15 amps or 2000 watts. ![]() ![]() Rated for 3000 watts peak output, allowing the use of devices with high inrush requirements. It makes van life so much more convenient! This converter has two standard 110V outlets and two 220V international-style outlets on front. Van dwellers who want to plug in to electric car chargers to charge their batteries or operate appliances can easily do so now. A converter is another name for a battery charger. It is a very useful device for camper vans and RVs. Most RVs have converters already fitted, but if you’re converting a van to a camper, this is a component to include in your electrical design. It converts any electric vehicle charging station to a regular 120V wall outlet capable of operating any appliance. This specially designed power converter is a step-down transformer connected to a J1772 EV charger receptacle, enabling you to operate all standard 110V appliances at electric vehicle charging stations. ![]()
