Volnex Alpha 2.56 25.6V 100Ah Lithium Battery Price in Pakistan

The Volnex Alpha 2.56 is a 24V wall battery: 25.6V nominal, 100Ah and 2.56 kWh. It is the 24V entry point of the Volnex Alpha series, and Volnex lists a 10-year brand warranty on it. LiFePO4 cells mean no water top-ups, no acid fumes, stable voltage under load and about 90% usable capacity each day.

Backup at common loads: two fans, lights and a fridge (about 300W) run for about 7 hours. Four fans, eight LED lights and a TV (about 450W) run for about 5 hours. A 1-ton inverter AC with a fan and lights (about 920W) runs for about 2 hours. It is a good match for load shedding in a small or medium home, not for all-night cooling.

It fits 24V UPS units and 24V solar inverters that allow a lithium or custom LiFePO4 charge profile. It replaces a pair of 12V tubular batteries with one slim pack on the wall. If your UPS was built only for lead-acid, check the charge settings first; the UPS guide (Lithium Battery for UPS: What Works and What to Check) explains how. No IP rating is listed for the Alpha, so keep it indoors.

In the Volnex line, the Alpha 5.12 keeps the same wall body style and 10-year warranty but moves to 51.2V for 48V hybrid inverters, with twice the energy. The Armor 5.12 is the IP65 version of the 5kW pack. The Alpha 16 is the 16.07 kWh floor unit. Choose the Alpha 2.56 if you have a 24V inverter today and want a long warranty. If you are about to buy a new hybrid inverter, a 48V battery like the Alpha 5.12 gives more room to grow.

Who should buy it? A household with a 24V UPS or 24V solar inverter that wants to stop buying tubular batteries every few years and wants one long warranty to cover the replacement. Who should skip it? A home that plans to buy a new 48V hybrid inverter soon, because this 24V pack cannot be moved to a 48V system later. Also skip it if you want AC through the night. Keep your warranty card and invoice safe, because a long warranty is only useful if you can show the purchase date. Ask us about the claim process before you order.
