Phoenix RLC-1.3-X1 Cube 12.8V 105Ah Lithium Battery Price in Pakistan

The Phoenix RLC-1.3-X1 Cube is a 12.8V lithium battery rated at 105Ah, which gives about 1.3 kWh of stored energy. Its compact cube shape takes less floor space than a tall tubular battery, and it fits well under a desk or beside a UPS. The cells are LiFePO4, so there are no water top-ups, no acid fumes, and about 90% of the capacity is usable each day without the damage that deep discharge causes in lead-acid.

Backup at small loads: one fan and two LED lights (about 100W) run for about 11 hours. A Wi-Fi router with CCTV (about 30W) runs for about 36 hours, so it is a very good fit for home internet, security cameras and a small office counter. It is not sized for an AC, a fridge or a water pump.

It works with single-battery 12V UPS units, 12V inverters and small 12V solar kits with a lithium-ready charge controller. If your UPS was set for lead-acid, check the charging mode first: our UPS guide (Lithium Battery for UPS: What Works and What to Check) explains what to look for. Keep it indoors in a dry place; no IP rating is listed.

The extra 5Ah over a common 100Ah 12V battery gives a small edge in backup, about 1.3 kWh against 1.28 kWh. In the Phoenix cube range, the RLC-2.7-X1 is the 24V version (25.6V 105Ah, 2.7 kWh). It roughly doubles the backup and lists 5,000+ cycles and a 3-year warranty. Phoenix has not published a cycle figure or warranty period for this 12V cube, so ask us for the terms before you order. If you want the published warranty and your system is 24V, the RLC-2.7-X1 is the safer choice.

Who should buy it? A student room, a small shop, a pharmacy counter or a home that only needs one fan, a few lights and the Wi-Fi to stay on during load shedding. It is also a clean upgrade if your old 12V battery keeps swelling or needs water every few weeks. Who should skip it? Anyone who wants a fridge or AC on backup, or whose UPS takes two batteries in series. For those homes, a 24V or 48V battery is the right step up. Before you swap, note your UPS model and battery voltage so we can confirm the fit.
