Go Power! Converter Battery Chargers The Go Power! Battery Converter Chargers are compact, powerful battery converter chargers that offer fast, accurate battery charging at a reasonable cost. Using state-of-the-art, converter switch-mode technology, Go Power! Battery Chargers are reliable, compact and lightweight. For RV systems, they feature high continuous output to feed your 12- or 24-volt loads when plugged into shore power. All models feature switchable output voltage modes, one for float charging and one for rapid charging. The optional GPC-Smart Controller converts the Go Power! models to a three-stage charger, with an automatic "equalization" stage to periodically boost charge batteries. This is especially useful for batteries which often sit idle for long periods. Model: GPC-Smart Controller.
