Automatic voltage sensing, selectable LiFePO4, lead-acid and AGM modes, lithium BMS activation and an IP67 epoxy-filled enclosure make it a practical run-and-gun charging solution for bass boats and tournament anglers.

This charger monitors the source side, steps the voltage up and applies a controlled 36V charge whenever the source rises above the engine-running threshold, with no direct battery tie and no manual ignition trigger. It supplements trolling-motor energy but is not a replacement for a full dockside AC recharge.\u003c\/p\u003e\n\n\u003ch3\u003ePlan your alternator capacity\u003c\/h3\u003e\n\u003cp\u003eA 36V \/ 10A output represents roughly 360 W before losses, so the input-side current on a 12V system can be substantial and is not a fixed 10 A. Before installation, confirm the outboard or vehicle charging-system rating, existing loads, available current margin, cable size, fuse protection and voltage drop. 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, so voltage-sensing control does not mean galvanic isolation. The red and black conductors within the same cable jacket must connect to the same battery, and grounding and polarity must be planned carefully. Follow the supplied wiring diagram and verify grounding, polarity, fusing and system compatibility before use.\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 a high level of ingress protection. Do not intentionally submerge the unit, and keep the ring terminals, cables and connections protected from rain, snow, standing water and damage. This charger is not fanless: keep more than 30 mm of clearance and never block the cooling surfaces or the fan. 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-36V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSingle-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\u003c\/td\u003e\n\u003ctd\u003e36 V \/ 10 A (about 360 W nominal), one compatible 36V auxiliary battery\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBattery modes\u003c\/td\u003e\n\u003ctd\u003e36V LiFePO4, lead-acid or AGM (MODE button)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnections\u003c\/td\u003e\n\u003ctd\u003ePre-wired ring-terminal leads (red positive, black negative)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eReplacement fuse\u003c\/td\u003e\n\u003ctd\u003e15 A\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 × 95 × 68 mm (about 9.84 × 3.74 × 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 labeled source leads to the compatible 12V or 24V starter-battery system, select the auxiliary battery chemistry and connect the 36V output using the supplied wiring diagram. The battery type cannot be changed while charging, so disconnect the output ring terminals before selecting a different mode. Secure the charger to a rigid surface and support the leads against vibration and abrasion. Use appropriate input and output fusing, disconnects and marine-grade cables 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 the 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?
