RB36V40
36V 40Ah
Lithium Deep Cycle Battery
Group 31

Fish all day with 36V lithium power! The RB36V40 is a durable and long-lasting 36V lithium iron phosphate power source designed specifically for marine use. The parallel design brings a simpler set-up and more capacity, keeping you out on the water for longer.

Simpler Set-Up

Get max voltage with minimum hassle thanks to the RB36V40's parallel set-up. The improved connectors and small footprint make on-board installation a breeze, while the battery's low weight means you'll never sacrifice speed through the water.

Marine-Optimized

The RB36V40 is built for the marine environment. You'll get year-round peace of mind with the newly enhanced case, featuring an IP67 waterproof rating, and a new glue channel and screw-latched enclosure to protect against airborne contaminants.

Longer Lasting

The parallel set-up means quicker and easier charging, but it also means there's more in the tank when you need it. The RB36V40 offers 20% greater capacity than its series equivalent*, translating to enhanced run times to keep you out on the water for longer. *Based on 3 @ 40Ah in parallel vs 3 @ 12V 100Ah in series

Suitable For Commercial Use

The benefits of parallel power translate equally well to various commercial applications. For example, the battery's increased capacity, faster charge time, and reduced downtime and maintenance costs make it ideal for use in floor cleaning settings.
