LITHIUM-IRON PHOSPHATE (LIFEPO4) DEEP-CYCLE BATTERIES

Lithium-Iron Phosphate, or Deep Cycle LiFePO4 battery, are another alternative to Lead-Acid or AGM Deep-Cycle batteries.  While LiFePO4 batteries have a much higher upfront cost than Lead-Acid or AGM, there are many features that may make the investment worthwhile for your setup.  For many in today’s market, LiFePO4 batteries are the battery of choice for serious deep-cycle applications.

Lithium-Iron Phosphate batteries are less than half the weight of their lead acid competitors.  In most cases, LiFePO4 batteries can also be discharged up to 80% and more without affecting the cycle life of the battery.  The cycle life of these deep-cycle batteries can also be up to 3x-5x longer than that of their Lead-Acid counterparts.  These batteries can also be charged 2x-3x faster due to their ability to safely accept a higher charging current.

Each LiFePO4 battery that is listed on our website also has its own internal “BMS” or Battery Management System.  This provides many safety and performance  features such as:  Over and under voltage protection, over and under temperature protection, automatic cell balancing and more.  These features are actually built directly in to the battery therefore eliminating the need for an external unit to perform the same function.

These are just a few of the many features of Lithium-Iron Phosphate Batteries (LiFePO4).  Since everything has its advantages and disadvantages, do some research for yourself and see which option would best suit your needs and your budget.  Whether you need Lead-Acid, AGM or Lithium-Iron Phosphate, we at Continuous Resources, LLC have you covered.

What is the deep cycle battery?

A deep-cycle battery is a battery that is designed to be able to store a large quantity of energy while having the ability to discharge from 100% down to 0% without hurting the battery.

A deep-cycle battery also ensures that a steady amount of power is being delivered to applications over a long period of time without interruption or failure. It is constructed with thicker plates and a denser active material ratio. Due to these features, a deep-cycle battery achieves greater cycling capacities.

What is DOD (Depth of Discharge)?

The Depth of Discharge (DOD) of a battery represents the percentage of the battery that has been discharged relative to the overall capacity of the battery. For example, if a battery has a nominal capacity of 100kWh and discharges 30kW, the Depth of Discharge comes out to be 30%.

Its DOD is (30x 1) / 100 = 30%.

The more often a battery is charged and discharged, the shorter the battery life will become. It is generally not recommended to completely discharge a battery as it will greatly reduce the battery life. Many battery manufacturers specify the recommended maximum DOD in order to maximize the battery performance.

If a manufacturer of a 10 kWh battery recommends a maximum DOD of 80%, the battery should not use more than 8 kWh without charging. The DOD is an important factor to consider because a higher DOD means that more of the energy in a battery can be used. The DOD of many modern lithium-ion batteries is 100%.

A battery’s “cycle life,” the number of charge/discharge cycles in its life, depends on how much battery capacity is typically use. Rather than completely draining a battery to its maximum DOD, a user will be able to attain more cycles in their battery regularly discharging it with a lower percentage of charge.

For example, a battery may have 15,000 cycles at a DoD of 10%, but only have 3,000 cycles at a DoD of 80%.

What applications need deep-cycle battery?

      • Floor Machines
      • Electric vehicles
      • Materials handling
      • Renewable energy
      • Aerial work platforms
      • Commercial transit
      • RV and Marine
      • HME Mobility Telecom UPS
      • Security Electronics

      All of these applications require high energy retention, deep-cycle discharge, a large number of cycle lives, and a stable discharge performance.

Why choose  deep cycle LiFePO4 battery?

Another way to think of the DOD is the extent to which discharge begins to stop during use. 100% DOD refers to discharge at full capacity.

The life of a lead-acid battery is greatly affected by the DOD. A lead-acid battery is likely to fail quickly on a user as it normally only allows 50 to 80% DOD.

In contrast, A LiFePO4 (Lithium Iron Phosphate) battery, which is newer technology, has a deep-cycle discharge, so it can reach 2000 cycles with 100% DOD. Lithium batteries can also be discharged at a specific C-rating. With a working temperature of 25° C and a discharge rate of 0.5C, a LiFePO4 battery can reach 4000 to 6000 cycles.

Compared to lead-acid batteries, the advantages of deep-cycle lifepo4 batteries are the following:

      • Eco-friendly
      • Good high-temperature resistance
      • Good safety characteristics
      • No memory effect
      • Higher-capacity compare with same size lead-acid battery
      • Longer cycle life than other lithium-ion batteries

SPECIFICATIONS

STORAGE CAPACITY 100 ampere hours (Ah). Brava Lithium batteries provide consistent power for all 100 amp hours. LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.
