Phoenix RLC-2.7-X1 Cube 25.6V 105Ah Lithium Battery Price in Pakistan

The Phoenix RLC-2.7-X1 is the 24V member of the Phoenix cube family: 25.6V nominal, 105Ah and about 2.7 kWh. In searches it often appears as a Phoenix 2.5kWh lithium battery. Phoenix lists 5,000+ cycles and a 3-year brand warranty for it. The LiFePO4 cells need no water, give off no fumes, and let you use about 90% of the capacity every 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, enough for a short outage but not a full night of cooling.

It suits 24V UPS units and 24V solar inverters that support a lithium or custom LiFePO4 charge profile. It takes the place of the two 12V tubular batteries most 24V systems use, in a cube that takes far less floor space. The settings guide (Lithium Battery Settings for Growatt, Deye, Inverex and Knox) shows which charge values to set. No IP rating is listed, so keep it indoors in a dry, shaded place.

How it compares: the 12V RLC-1.3-X1 cube holds about half the energy (1.3 kWh) and has no published cycle or warranty figure. This 24V cube doubles the energy and lists 5,000 cycles and 3 years. For 48V hybrid solar, Phoenix offers the RLR-5.1-X1 rack (5.12 kWh) and the RLW-5.4-X1 wall battery (5.37 kWh). Choose the RLC-2.7-X1 if your inverter is 24V and you want a small, tidy battery with a published warranty. At 5,000 cycles, one cycle a day adds up to more than 13 years of rated cycling, but the 3-year warranty is the term Phoenix commits to.

Swapping from tubular is quick: the two old 12V batteries come out, the cube goes in, and the UPS or inverter is set to a lithium charge mode. Because there is no acid, the cube can sit in a bedroom corner or lounge cabinet without fumes or stains. Give it space to breathe and keep it away from a sunny window, since heat is the main thing that shortens lithium life.
