Crown Elektra 5.12 Pro IP21 51.2V 100Ah Lithium Battery Price in Pakistan

The Crown Elektra 5.12 Pro IP21 is a 51.2V, 100Ah lithium iron phosphate battery that stores 5.12 kWh. It mounts on the wall and has an IP21 case, which is an indoor rating: fine in a dry room, not for rain or splashes. Buyers search for this size as a "5kw lithium battery" or "48v 100ah lithium battery price in pakistan".

What makes the Pro stand out in the Crown 5kW line is its published specs. It is the only Crown 5kW model on our sheet with both a 6,000+ cycle rating and a stated 10-year brand warranty. The Elektra 5.12 Lite IP21 has the same size, mounting and IP21 case but lists neither cycles nor warranty. The CMLB-51.2 100Ah also stores 5.12 kWh but lists no IP rating, cycles or warranty. If you plan to keep the battery for a decade, the Pro is the one whose terms you can hold the seller to.

From a full charge: - 2 fans + lights + fridge (about 300W): about 14 hours - 4 fans + 8 LED lights + TV (about 450W): about 9 hours - 1-ton inverter AC + fan + lights (about 920W): about 5 hours

With a working-from-home setup of a laptop, monitor, router, fan and lights at about 200W, the formula gives about 21 hours. The Pro suits 48V hybrid and off-grid inverters such as Growatt, Inverex, Knox, Fronus and Deye. Set the battery type to lithium, take the charge and cut-off voltages from the Crown datasheet, and check BMS communication support if your inverter has it. If you are unsure whether your inverter will talk to the battery, read the compatibility guide (Which Lithium Battery Works With My Inverter?).

Fit it on a strong indoor wall in a cool, shaded place with short cables and a DC breaker. With 6,000+ rated cycles, a daily solar cycle can carry on for well over a decade before the capacity drops noticeably, and the 10-year warranty covers most of that time. Keep the warranty card and invoice, and register the battery if Crown asks you to.

Choose the Pro if you value a long written warranty at the 5kW size. If you need more storage, look at the Crown CMLB-51.2 230Ah on the 10kW page (10kW Lithium Battery). Syed Non Custom Solar lists every Crown model on the brand page (Crown Lithium Battery prices).
