About the Felicity Solar FL-OPzV-2500AH-2V 2V 5kWh Gel Battery

The Felicity Solar FL-OPzV-2500AH-2V is a single 2V tubular-plate gel cell rated 2500Ah on the 10hr-rate to 1.8V per cell @25°C, which is 5 kWh from one cell. It weighs 190 kg, measures 487 x 212 x 807 mm, accepts a 500A maximum charging current and delivers a 10000A maximum discharge current. Internal resistance is 0.35 mΩ and self-discharge stays under 2% per month. Charging is bounded by a 2.4V maximum charging voltage, a 2.25-2.3V float band and a 2.37-2.4V cycle service voltage, with 1.6-1.9V as the cut-off. The cell holds one cell per unit in an A.B.S. (UL94-HB) container, with UL94-V0 optional, and terminates in thread insert & bolt (F10-M8) hardware. It charges between 0-50°C, discharges from -40 to 70°C, stores from -20 to 60°C and performs best at 20-30°C. At 190 kg and 487 x 212 x 807 mm per cell, allow for mechanical handling and rack loading at that figure. We are an authorised Felicity Solar distributor and supply the OPZV-2500AH-2V from our own stock, and the FL-OPzV-2500AH-2V carries a 2 Years warranty.
