12V 500Ah AGM Deep Cycle Battery Bank (6 × 2V) | 4Boats

12 V 500 Ah AGM deep cycle battery bank built from six 2 V cells for large power systems and energy storage.

• Benefits of 2 V battery connection: This battery bank features 2 V batteries, offering important advantages over banks made up of 12 V batteries.
• Significantly improved longevity: 6 x 2 V cells are connected exclusively in series so each cell is charged and discharged evenly, giving considerably longer service life than typical 12 V-bank arrangements.
• Deeper discharge capability: Thicker metal plates inside the 2 V batteries allow more energy to be drawn compared with banks comprised of 12 V batteries.
• Suitable applications: Long service life and improved depth of discharge make this bank ideal for large power systems for motorhomes, caravans and boats; solar, wind and hybrid energy systems; household off-grid power; emergency/backup UPS systems; telecommunications and networking equipment; and power stations.
• AGM battery benefits: 6 x AGM (Absorbed Glass Mat) batteries — maintenance free (no electrolyte top-up), extremely safe (non-spillable, sealed with terminal protection), long service life, low self-discharge and high resistance to shock and vibration. Supplied with a detailed user manual and metal plate connectors.
• Specifications (per 2 V battery): Nominal voltage 2 V; nominal capacity 500 Ah (10h rate) / 508 Ah (20h rate); maximum charging current 100 A; cycle lifetime at 30% D.O.D. ≈ 1,200 cycles; pressure control: safety valve installed; terminal type M10 bolts; operating temperature -10°C to +40°C (14°F to 104°F); size 242 x 174 x 365 mm (9.53 x 6.85 x 14.37 in); weight 27 kg (59.5 lb).
• Specifications (entire 12 V battery bank): Nominal voltage 12 V; nominal energy 6 kWh; maximum charging current 100 A; charging voltage (float/standby) 13.7 V; temperature compensation: cycle use -30 mV/°C, standby use -18 mV/°C; size 1,150 x 250 x 370 mm (45.28 x 9.84 x 14.57 in); weight 170 kg (375 lb).
• Installation and terminals: Robust M10 bolt terminals and included metal plate connectors simplify series assembly and secure connections for large power installations.

Care and compatibility: Use a suitable charger or charge controller configured for AGM batteries and the bank's charging voltages; follow the supplied user manual for safe installation, ventilation and maintenance recommendations.
