Deep Cycle Lithium Battery

All batteries across the PowerPaul® range are classed as ‘Deep Cycle’ lithium batteries. In this article we detail what defines a Deep Cycle lithium battery.

Deep Cycle lithium (LiFePO4) batteries are designed, built and optimised for steady prolonged energy delivery, long-term energy storage, deep discharge cycles and stable power output. This makes them ideal for off-grid travelling and camping, marine applications and remote or mobile off-grid power systems.

• Designed for sustained energy delivery over extended periods
• Can be safely discharged to a BMS SOC of 0% without significant degradation
• More thermally stable than LiPo or NMC lithium batteries (lower risk)
• Can withstand harsh temperature conditions (operational range -20°C to 60°C)
• Built-in Battery Management System (protection against unsafe usage) 

LiFePO4 (Lithium iron phosphate) Deep Cycle lithium batteries provide a stable voltage output throughout the discharge cycle and do not experience major voltage drops under load. They can also be charged anytime without reducing lifespan (no memory effect).

Although they may feature similar chemistry, not all lithium batteries provide safe and consistent Deep Cycle usage without significant degradation. Other chemistry lithium batteries work better during short energy bursts (ideal for power tools, high performance EVs or UPS systems) rather than sustained long-term discharge. In saying that, more and more regular EVs are starting to use LiFePO4 batteries for the safety aspect of their particular Li chemistry.

Deeper discharge, higher cycle life

Deep Cycle lithium batteries feature a higher cycle life and longer discharge cycles. Notable design characteristics include thicker electrodes to withstand frequent cycling, cell configurations specifically for slow energy release, and battery management system (BMS) configurations that allow deep discharge. 

PowerPaul® Deep Cycle lithium batteries are designed for optimised health, efficiency and protection against degradation. Each battery features high-energy density (to provide maximum capacity in minimum space) and an expected cycle life of 10+ years (depending on usage). 

PowerPaul® Deep Cycle lithium batteries will charge and discharge between temperatures of 0-60C° and will continue to discharge to -20C° (a wide operating temperature range – making them versatile for use in both hot and cold climates).

Long term energy storage, stable output and prolonged delivery

Deep Cycle lithium battery systems benefit off-grid applications requiring steady and reliable power for appliances, systems, equipment and electronics; without the need for constant recharging. 

PowerPaul® Deep Cycle lithium batteries are high-capacity, compact and lightweight making them compatible with a wide range of electrical systems commonly used in recreational vehicles, off-grid and mobile power systems. 

• RV’s, motorhomes caravans
• 4WD’s, ute trays and canopies
• Campervans, pop-up campers 
• Off-grid cabins and tiny homes
• Marine vessels (boats, yachts, houseboats)
• Buses and trucks

Frequently asked questions

What is the difference between a Deep Cycle and a non-Deep Cycle lithium battery?

Deep Cycle lithium batteries are built for deep discharges and can be safely discharged to 0% SOC regularly, without rapid degradation. Non-Deep Cycle lithium batteries have a higher discharge rate for quick, high-power output and should not be deeply discharged too frequently.
