The Lithium Rhino LR38V120AH-M is a 36V lithium marine battery that takes over that entire bank in one sealed, IP67 waterproof case.\u003c\/p\u003e\n\n\u003cp\u003eAt 120 amp-hours and 4,608 watt-hours, this is the long-day option in the Rhino marine line. Lithium Rhino rates it for 288 minutes of reserve at a steady 25-amp draw, which is close to five hours of hard pulling before you even get into the lighter throttle settings most anglers use while working a shoreline. Lithium iron phosphate (LiFePO4) also holds its voltage until it's nearly empty, so the motor has the same push on the ride back to the launch as it had on the first drift.\u003c\/p\u003e\n\n\u003ch2\u003eWhat This 36V Lithium Marine Battery Replaces\u003c\/h2\u003e\n\u003cp\u003eOne battery does the work of the three-battery 36V bank.

Lithium needs a lithium charge profile, and the kit's 15A waterproof charger handles it (about eight hours from empty).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOne honest limit: this pack is built to run as a single battery. Lithium Rhino does not support wiring two of them in series, so don't plan on stacking it for a 72V setup. It is also a deep-cycle battery. It will not crank an outboard. If you need starting power, look at the Rhino 12V Dual Cranking model or call us.\u003c\/p\u003e\n\n\u003cp\u003eMeasure your battery compartment before you buy: the case is 19.76 by 10.51 by 8.70 inches. Tournament anglers and anyone working Lake Erie structure out of Mentor Harbor from sunrise on get the most from the extra capacity. Shopping for a 36 volt lithium trolling motor battery for shorter trips? The 36V 65Ah version weighs 45.4 lb. Call us with your motor model and your compartment size, and we'll help you pick between them.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's in the Kit\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eLithium Rhino 36V 120Ah IP67 LiFePO4 marine battery\u003c\/li\u003e\n  \u003cli\u003e15A waterproof lithium charger\u003c\/li\u003e\n  \u003cli\u003eFull-color round console gauge with external power button\u003c\/li\u003e\n  \u003cli\u003eMounting hardware\u003c\/li\u003e\n  \u003cli\u003eBluetooth connection to the free Rhino app\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e36V bow-mount and transom trolling motors\u003c\/li\u003e\n  \u003cli\u003e36V house loads on boats built around a 36V system\u003c\/li\u003e\n  \u003cli\u003eMarine electronics, with a step-down converter for 12V gear (not included;
