ABYSS 36V 75Ah Lithium Deep Cycle Battery — Bluetooth Edition

ABYSS 36V 75Ah Lithium Deep Cycle Battery — Bluetooth Edition

When a full day on the water isn't enough, the ABYSS 36V 75Ah Lithium Deep Cycle Battery with Bluetooth delivers the extended runtime serious anglers demand. With 25% more capacity than the 60Ah model, this battery is built for long tournament days, big water, and high-draw motors. Whether you're running a Garmin Force Kraken, a Minn Kota Ulterra Quest, a Power-Pole MOVE PV, or a Rhodan Gen5 — the 75Ah gives you the headroom to fish harder and longer.

Why Go Lithium?

Lead-acid batteries sag under load, lose capacity as they age, and weigh your boat down. The ABYSS 75Ah lithium battery maintains a flat discharge curve from full to near-empty, so your motor runs at full power all day — not just the first few hours.

Bluetooth Monitoring — Real-Time Power in Your Pocket

The integrated Bluetooth module pairs with the ABYSS app to give you live state-of-charge, voltage, temperature, and cycle count data on your phone. Know exactly how much runtime you have left before you need to head in.
