Sterling Power 12V to 24V Auxillary Battery Maintainer

The Sterling Power BM12241 Battery Maintainer is a 12V-to-24V solution designed to keep your auxiliary battery bank topped up by drawing power from the primary battery—only when it’s being charged by a source like a battery charger, solar panel, or wind generator. Unlike traditional designs, this maintainer uses efficient FET technology instead of relays. FETs consume just 1.5 mA of power, making them ideal for low-power charging sources. With no moving parts, they operate silently and are built for long-lasting, maintenance-free performance.
