1.28kWh Felicity FLA12100PG2 12V 100Ah Grade A Lithium Battery – 6000+ Cycles

The 1.28kWh Felicity FLA12100PG2 12V 100Ah Grade A Lithium Battery is a compact energy-storage solution designed for 12V battery applications, with the flexibility to connect up to 4 units in series where a higher-voltage battery configuration is required.

Unlike Felicity wall-mounted solar batteries, the FLA12100PG2 is a non-wall-mounted battery, making it suitable for installations where the battery is positioned on a suitable supporting surface or within an appropriately designed battery enclosure.

Its standout specifications include ≥6000 cycles at 25°C, 95% DOD, a recommended charging current of less than 100A, and recommended discharge power of less than 1,250W.

With 1.28kWh nominal storage from a 12V 100Ah configuration, this model is particularly useful where customers need compact modular storage rather than a single large-capacity battery.

1.28kWh Compact Storage Advantage

The FLA12100PG2 provides 1.28kWh of nominal energy storage in a compact 12V 100Ah battery format.

This makes it particularly useful for applications that do not require a large 5kWh, 10kWh or higher-capacity battery from the outset.

Instead, the system can be designed around a smaller battery platform while retaining the ability to use multiple units in an approved series configuration where required.

Up to 4 Batteries in Series

A major differentiating feature of the FLA12100PG2 is its support for up to 4 units connected in series.

Using the supplied 12V rating, this allows nominal series configurations such as:

In a series connection, the voltage increases while the Ah capacity remains 100Ah.

All batteries used in a series bank should be compatible, correctly matched and connected according to Felicity’s requirements.

6000+ Cycle Advantage

The FLA12100PG2 is specified for:

≥6000 cycles at 25°C

This gives the battery a strong specification for applications involving regular charge and discharge cycles.

Cycle performance is specifically stated at 25°C, so actual service life can vary with operating temperature, charging behaviour, discharge depth and overall system conditions.

95% Depth of Discharge

The battery is specified at:

95% DOD

Depth of Discharge describes how much of the battery’s capacity can be discharged relative to its stated capacity under the specified operating conditions.

This high DOD specification allows a substantial proportion of the battery’s stored energy to be utilised.

Actual operating settings should still follow Felicity’s recommended battery parameters.

Recommended Charge Current Below 100A

Felicity specifies a recommended charging current of:

<100A

The charger, solar charge controller or compatible inverter should therefore be configured so that charging remains within the battery’s recommended operating requirements.

This is particularly important when multiple batteries or higher-power charging equipment are used.

Recommended Discharge Power Below 1,250W

The specified recommended discharge power is:

<1,250W

This is an important consideration when pairing the FLA12100PG2 with an inverter.

The battery’s 1.28kWh capacity describes stored energy, while its recommended <1,250W discharge power describes the power level that should be respected according to the supplied specification.

A high-wattage inverter should therefore not automatically be paired with a single battery without checking the required battery configuration and discharge demand.

Grade A Battery Advantage

The FLA12100PG2 is supplied as a Grade A battery, making the cell-grade specification a key feature of this particular model.

Combined with its stated:

≥6000 cycles + 95% DOD + 100Ah capacity

the battery is positioned for applications requiring regular energy storage and repeated cycling.

Non-Wall-Mounted Design

Unlike wall-mounted solar storage batteries, the FLA12100PG2 is specifically non-wall-mounted.

This makes it appropriate for battery installations using a suitable:

🔋 Battery Area

🗄️ Battery Cabinet

⚡ Equipment Compartment

🏠 Dedicated Energy-Storage Location

The battery should be positioned securely and according to Felicity’s required installation orientation and environmental conditions.

Applications / Use Cases

☀️ Small Solar Systems – compact storage for appropriately designed low-voltage solar installations.

🏠 Home Backup – suitable for selected essential loads when paired with compatible equipment.

💡 Lighting & Electronics – useful for appropriately sized lower-power backup applications.

⚡ 12V Battery Systems – direct fit for compatible equipment designed around the battery’s specified voltage.

🔋 24V / 36V / 48V Battery Banks – up to four units can be connected in series according to the supplied specification.

🏪 Small Business Backup – modular storage for appropriately calculated essential loads.

Battery & Inverter Matching

Correct inverter matching is especially important with this battery.

Check:

• Required battery voltage
• Number of batteries in series
• Inverter DC input range
• Battery charge-current requirements
• Recommended <100A charge current
• Recommended <1,250W discharge power
• Required backup duration
• Cable sizing
• DC protection
• Battery configuration requirements

A 48V inverter, for example, should not be assumed compatible with one 12V battery simply because four of these batteries can be configured in series. The complete battery-bank and inverter requirements must be checked.

Usage & Installation Notes

• Do not exceed the recommended <100A charge current
• Observe the recommended <1,250W discharge power
• Up to 4 units may be connected in series according to the supplied specification
• Use correctly matched batteries when building a series bank
• Follow Felicity requirements for series connection
• Use correctly sized battery cables
• Install suitable DC protection
• Ensure connections are correctly tightened
• Protect battery terminals against accidental short circuits
• Install in a suitable non-wall-mounted location
• Follow the specified installation orientation
• Keep the battery within recommended operating temperatures
• Do not expose the battery to uncontrolled moisture or heat
• Follow Felicity charging and operating parameters
