12V 500Ah AGM deep-cycle battery bank (6 x 2V batteries) for large power systems and energy storage. Benefits of 2V battery connection: This battery bank features 2V batteries, offering significant advantages over battery banks made up of 12V batteries. These include significantly improved longevity. These 2V batteries are connected in series, as opposed to 12V battery banks, which require a complex combination of series and parallel connections.

By connecting only in series, each 2V battery is charged and discharged at an even rate. Thanks to these stable and balanced charging cycles, this battery bank has a considerably longer service life compared to a bank consisting of 12V batteries.

Deeper discharge capability: The thicker metal plates inside these 2V batteries allow for more energy to be drawn from the bank than if it were comprised of 12V batteries.

Suitable applications: The long service life and improved depth of discharge of this battery bank make it ideal for applications requiring constant, reliable, and powerful energy supply. Such applications include, but are not limited to:

Large power systems for motorhomes, caravans, and boats

Solar, wind, and hybrid energy systems

Household off-grid power systems

Emergency or back-up UPS systems

Energy storage for telecommunications or networking equipment

Power stations

Benefits of AGM batteries: This battery bank features 6 x AGM (Absorbed Glass Mat) batteries. In AGM batteries, all electrolyte is absorbed into a special sponge made of glass fiber. Important benefits of AGM batteries include:

Maintenance free: No need for liquid or electrolyte top-up.

Extremely safe: Non-spillable and completely sealed, with protective covering of the terminals.

Long service life: Longer-lasting than standard wet-cell batteries due to less degradation and corrosion inside the battery.

Low self-discharge rate: AGM batteries are less prone to sulfation and hold charge for longer than flooded batteries.

Highly resilient: Good resistance to shock and vibration.
