Reliable Marine Starting and Deep Cycle Power in One Compact Footprint

• Delivers dual-purpose performance with 800 Cold Cranking Amps (CCA) for engine starts and 80Ah of deep cycle capacity.
• Provides up to 4,000 charge cycles at 80% Depth of Discharge, drastically outlasting traditional lead-acid alternatives.
• Protects your investment natively with an integrated Battery Management System (BMS) featuring active cell balancing and low-temperature charging cutoff.
• Fits seamlessly into existing Group 24 battery trays for a straightforward drop-in installation.

What This Upgrade Fixes

Traditional lead-acid marine batteries struggle to balance deep cycling with high-amp engine starting. They degrade quickly, suffer permanent damage when drawn down too far, and require constant maintenance. This LiFePO4 upgrade eliminates battery anxiety by providing robust, consistent voltage through the entire discharge cycle, heavy-duty starting power, and maintenance-free operation in a rugged, IP67-rated waterproof enclosure.

Key Specifications

Frequently Asked Questions

Can I use this battery to start my boat engine?
Yes. Unlike traditional deep cycle lithium batteries, this unit is built for dual-purpose applications and safely provides 800 CCA for reliable engine starting alongside its deep cycle capabilities.

How does this battery handle cold weather?
The advanced BMS features a low-temperature charging cutoff. This prevents the system from accepting a charge when internal temperatures drop below freezing (32°F), effectively protecting the lithium cells from permanent damage.

Is the battery waterproof?
Yes, it carries a strict IP67 rating. This means the enclosure is completely dust-tight and can survive temporary immersion in water, making it a safe and rugged choice for demanding marine environments.
