RB300 12V 300Ah Deep Cycle Lithium Battery

Description

The RB300 is a high-capacity lithium iron phosphate (LiFePO₄) battery designed to replace heavy lead-acid battery banks in sailboats, RVs, and solar energy systems. Weighing only 76 lbs, it delivers a true 300Ah capacity while being significantly lighter and more efficient than traditional alternatives.

Key Features:

• Lightweight & High Power – Weighing only 76 lbs, it provides 100% of its rated capacity while being half the weight of lead-acid batteries.
• Temperature Tolerant – Performs 2.5x better in low temperatures and operates safely up to 149°F (65°C).
• Fast Charging – Charges faster than lead-acid with more usable energy and up to 10 times longer lifespan.
• Long Life – Offers up to 10x the lifespan of lead-acid batteries, maintaining 80% capacity after 3,500 cycles.
• Maintenance-Free – No watering, no corrosion, and low self-discharge, ensuring power is available whenever needed.
• Constant Power Output – Voltage remains stable throughout discharge, unlike lead-acid alternatives.
• Partial State of Charge Tolerant – Unlike lead-acid batteries, performance and lifespan are not affected by a partial state of charge.
• More Usable Capacity – Unlike lead-acid, which requires oversizing and limited discharge, lithium provides 100% of its rated capacity at any discharge rate.
