Single stage converter/chargers can shorten the lifespan of your batteries by overcharging them. You can also find additional information about RV battery charger algorithms and discharging here. If your RV has an older single-stage converter/charger unit installed, then you should seriously consider replacing it. This 45 amp model, designed especially to charge wet cell and AGM batteries, measures 13.25 inches wide x 8 inches deep x 5.38 inches high and mounts in the lower section of the aforementioned OEM power centers. It can work for 75 amps for 12VDC and 37.5 Amp for 24VDC. It is one of the right power converters for RV that has a large charging capacity. for WFCO WF-8955) Smart Charger Camper Travel Trailer and Battery Charger. The smart charger and AC converter is a top choice for many RV owners that are looking for efficient and quality converter system for their camper or recreational vehicle. See more detailed RV battery charger information including equalization, three stage chargers and testing here. For the WFCO 8945PEC unit in my truck camper, I bought one of the best smart chargers in the market, the Progressive Dynamics 4645V. Ask question Questions on WFCO 8955PEC Converter: spogdog: RV Systems In this. Among inverter-chargers, well-known brands include Magnum and Xantrex. A popular multi-stage Converter-Charger is the Progressive Dynamics 9200 series, which is available with amp outputs from 45 to 80 amps. 48v LiFePO4 Server Rack Battery Deep Cycle Battery Charger Packages start. There are many multi-stage RV battery charger options available today. Port Solar Power Inverter & Deep Cycle Agm Battery 12 Volt 200AH for RV. The Float mode also keeps the battery safe at 100% charge almost indefinitely.

It is both faster charging when the battery is low and healthier for the battery as it nears full charge. This is adequate to keep the battery at the 100% charge level.Ī three stage RV battery charger is far superior to the single stage type. Once the battery appears to be fully charged (indicated by a low amp rate), the charger switches to Float mode, where it maintains a voltage of about 13.6. This stage is very much like the taper charge of a Single Stage charger. In this stage, the RV batter charger maintains a constant voltage (usually 14.1v – 14.8v) and lets the battery absorb as much current as it is willing to accept (sometimes called acceptance charging instead of absorption). At a predetermined level (which varies by charger make and model), it switches over to Absorption Stage. The RV battery charger does this by applying voltage as needed to keep the charge current at about 25% of the battery amp capacity.Īs the battery pushes back, the RV battery charger increases voltage to keep the amps constant, pushing as many amps as possible into the battery. Typically there are three stages, called Bulk, Absorption and Float.īulk charging is used to quickly take the battery from a very low charge up to about 60-80% charge.

Multi-stage charging is a more sophisticated method that optimizes charging based on the battery state of charge.
