Collection: Monster Marine Lithium

Monster Marine Lithium — LiFePO4 Batteries Built by Anglers, for Anglers. Lighter. Stronger. Longer.

Monster Marine Lithium was born out of frustration — dead AGM batteries, unnecessary weight, and unreliable power killing tournament days on the water. So they built something better. Engineered from the ground up using advanced LiFePO4 lithium technology, every Monster Marine battery delivers up to 10x longer lifespan than traditional lead-acid or AGM batteries at less than half the weight.

The battery lineup covers the full voltage spectrum — 12V, 24V, 36V, 48V, and 72V deep cycle trolling batteries for any motor configuration, plus dual-purpose cranking batteries that start your engine and power your electronics simultaneously. Bluetooth-enabled models connect to the Monster Marine app for real-time charge monitoring right from your phone. Built-in BMS protection guards against overcharge, over-discharge, overtemp, and short circuits — so your power stays reliable when it matters most.

The charger lineup matches the system — 12V, 24V, and 36V smart chargers, the all-new DYNO4 Dynamic Charger with multi-bank capability and on-the-run charging, and multi-voltage options that handle any setup on your boat.

Monster Marine also covers land — golf cart batteries, off-road applications, racing batteries, trail cam kits, and fishing reel batteries complete the lineup. Bill Dance approved. Tournament proven. Built to run all day.

Fish more. Charge less.
