Available as 20A, 40A, and 60A models, this charger family combines battery isolation and controlled charging for properly configured RV, van, boat, commercial vehicle, and off-grid mobile power systems. Rich Solar lists compatibility with AGM, flooded, gel, sealed, lithium iron phosphate, and lithium-ion battery categories, while the manual identifies selectable STD, GEL, AGM, LFP, and POWER positions; battery mode must be selected according to the connected battery manufacturer’s specifications. The charger supports traditional and smart alternators, while its D+ ignition connection is designed to activate charging only when the engine-running signal is present. Model selection, wiring, fuse sizing, battery settings, ventilation, and installation conditions must be confirmed for the exact system before use.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e12V Alternator Charging for Auxiliary Battery Systems\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis DC-DC charger is designed to connect between a 12V starter battery and a compatible 12V auxiliary or house battery. Rich Solar describes the unit as combining battery isolation with controlled alternator-based charging to help prevent reverse current between the starter and auxiliary batteries.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e20A, 40A and 60A Models for Different Charging Needs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eChoose RS-DC20 for 20A and 250W nominal output, RS-DC40 for 40A and 500W nominal output, or RS-DC60 for 60A and 750W nominal output. Each model uses a 12VDC nominal input, operates within a listed 10–16VDC range, and is rated above 85% efficiency at 14VDC and 30% load.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eLithium and Lead-Acid Battery Charging Modes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe mode-selection switch allows setup for supported battery types, including lithium iron phosphate, AGM, flooded, gel, and sealed batteries. Rich Solar documents two-stage charging for lithium batteries and three-stage charging for lead-acid batteries, with lithium activation designed to assist supported over-discharged lithium batteries after the correct battery mode is selected.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAlternator Integration, Protection and Installation Planning\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe charger includes documented over-voltage, under-voltage, over-temperature, reverse-polarity, and short-circuit protection functions. A D+ ignition terminal is required for normal operation, while an LC terminal can limit output to 50% of rated current for smaller or limited-current alternator applications. Rich Solar also identifies an optional RJ11 temperature sensor for temperature-compensated lead-acid charging only; the sensor is not for lithium batteries and is not included.\u003c\/p\u003e\n\u003c!-- Responsive Image\/Text Blocks --\u003e\n\u003cdiv style=\"display: flex;
