From one compatible 12V or 24V starter-battery system, it charges a separate 12V house or electronics battery (12V \/ 10A) and a compatible 36V trolling-motor battery (36V \/ 10A) at the same time. Automatic voltage sensing, selectable battery profiles, lithium BMS activation and an IP67 epoxy-filled enclosure make it a practical onboard solution for bass boats and mixed-voltage marine systems.

This charger bridges those auxiliary systems to a compatible 12V or 24V starter-battery source without connecting the batteries directly together, supplementing both banks whenever the source charging system is active. The starter battery remains the source side: the 12V output is for a separate auxiliary battery and must not be connected back to the battery used as the charger input. A DC-to-DC charger supplements but does not replace a full AC recharge at the dock.\u003c\/p\u003e\n\n\u003ch3\u003ePlan your alternator capacity\u003c\/h3\u003e\n\u003cp\u003eWith both outputs at full rating, the source-side demand can be substantial, especially on a 12V system. Before installation, verify the alternator or charging-system rating, starting-battery condition, existing electronics load, cable sizing, fuse protection, voltage drop and available charging margin. The manufacturer does not list an input-current rating on the product page.\u003c\/p\u003e\n\n\u003ch3\u003eNon-isolated design: wiring matters\u003c\/h3\u003e\n\u003cp\u003eThis is a non-isolated charger. The red and black conductors within the same cable jacket must connect to the same battery, and a black lead must never be connected to a terminal carrying red leads. Grounding, polarity, fusing and conductor routing must be planned before any battery is connected, and the supplied wiring diagram must be followed exactly. No NMEA 2000 or proprietary data network is required.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for the marine environment\u003c\/h3\u003e\n\u003cp\u003eThe enclosure is filled with pure epoxy resin for IP67 ingress protection in correctly installed onboard use. Protect the leads, terminals and connections, and do not intentionally or permanently submerge the unit. This charger is not fanless: keep more than 30 mm of clearance and never block the fan or the cooling surfaces. Do not charge lithium batteries below 0°C (32°F) unless the battery has approved heating or its manufacturer permits it.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eModel \/ SKU\u003c\/td\u003e\n\u003ctd\u003eCHG-DC-12V36V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eTwo-bank, non-isolated marine DC-to-DC battery charger\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSource input\u003c\/td\u003e\n\u003ctd\u003eCompatible 12V or 24V starter-battery system, 13–30 VDC (36V input not supported)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e12V source thresholds\u003c\/td\u003e\n\u003ctd\u003eStarts above 13.8 V, stops below 13.0 V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e24V source thresholds\u003c\/td\u003e\n\u003ctd\u003eStarts above 26.8 V, stops below 25.2 V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput bank 1\u003c\/td\u003e\n\u003ctd\u003e12 V \/ 10 A (about 120 W), 12V LiFePO4, lead-acid or AGM mode\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput bank 2\u003c\/td\u003e\n\u003ctd\u003e36 V \/ 10 A (about 360 W), 36V LiFePO4, lead-acid or AGM mode\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAggregate output\u003c\/td\u003e\n\u003ctd\u003eAbout 480 W nominal before conversion losses\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnections\u003c\/td\u003e\n\u003ctd\u003ePre-wired ring-terminal leads: one input pair, one 12V output pair, one 36V output pair\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eReplacement fuses\u003c\/td\u003e\n\u003ctd\u003e15 A (12V bank), 15 A (36V bank)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIndicators\u003c\/td\u003e\n\u003ctd\u003eNormal charge: POWER solid green, CHARGING solid red; full charge: both solid green\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProtection\u003c\/td\u003e\n\u003ctd\u003eShort-circuit, reverse-connection, overcharge and overtemperature protection\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eEnclosure\u003c\/td\u003e\n\u003ctd\u003eIP67, pure epoxy-filled, aluminum housing with bottom cooling plate and waterproof fan\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWorking temperature\u003c\/td\u003e\n\u003ctd\u003e-20°C to 40°C (-4°F to 104°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e250 × 149 × 68 mm (about 9.84 × 5.87 × 2.68 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003e6.5 mm holes, M6 screws recommended, more than 30 mm clearance\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2-year limited warranty: free repair or replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation notes\u003c\/h3\u003e\n\u003cp\u003eConnect the input pair to the starter-battery source, the 12V output pair to a separate 12V auxiliary battery and the 36V output pair to the compatible trolling-motor battery. Select the battery chemistry for each bank before charging; the mode cannot be changed while charging, so disconnect that bank's ring terminals first. Secure the charger to a rigid surface and protect every lead from vibration, abrasion, heat and sharp edges. Use appropriate fusing and disconnects, marine-grade cable and lugs sized for the current, run length and voltage drop, and follow the battery manufacturer's approved charging and balancing method for any 36V bank built from series-connected batteries. Disconnect and isolate all batteries before service, and never charge a frozen, damaged or unsupported battery.\u003c\/p\u003e\n\n\u003cp\u003eNeed help choosing a charger or batteries for your boat?
