Knox Powerwall 6.11 51.2V 100Ah Lithium Battery Price in Pakistan

The Knox Powerwall 6.11 is the Knox 5kW battery with the most complete spec sheet. It is a 51.2V, 100Ah LiFePO4 pack, so it stores 5.12 kWh, and it is wall-mounted. Knox rates it for 6,000+ cycles and gives a 5-year brand warranty. That warranty is the main thing that sets it apart from the 6.0 LCD and 6.1, which have the same capacity.

Backup time from full: about 14 hours on 2 fans, lights and a fridge (about 300W), about 9 hours on 4 fans, 8 LED lights and a TV (about 450W), and about 5 hours on a 1-ton inverter AC with a fan and lights (about 920W). So it covers a normal night of load shedding, or an evening of AC, and is ready to refill from solar in the morning. Try other loads in the backup calculator (Battery Backup Calculator).

Compatibility: it is a 48V-class battery for 48V hybrid and off-grid inverters. It pairs naturally with Knox inverters and also works with Inverex, Growatt, Fronus and Deye when set to lithium or user mode. Confirm BMS communication for your exact inverter model; our inverter compatibility guide (Which Lithium Battery Works With My Inverter?) lists what to check.

Installation: hang it on a solid indoor wall near the inverter. Our data lists no IP rating for this model, so install it indoors in a dry, shaded spot. Keep the warranty card and the battery serial safe, and register the warranty if Knox asks for it.

Life and warranty: 6,000+ cycles is far more than five years of use, so the battery should keep working long after the 5-year warranty ends. Five years of cover is still the most useful fact on this sheet, because it gives you a clear period of brand support. Read how long a lithium battery lasts (How Long Does a Lithium Battery Last in Pakistan?) for real-world tips.

A practical tip: Knox buyers often ask how to check the warranty online. Note the serial number from the label on the day of installation and keep a photo of it with your invoice. If you ever need a claim, these two things make the process much faster.

Knox 5kW family at a glance: all four (6.0 LCD, 6.1, 6.11, 7.1 IP65) hold 5.12 kWh. The 6.0 LCD adds a display and 6,000+ cycles; the 6.1 has no published cycles or warranty; the 7.1 adds IP65. The 6.11 is the pick for a written warranty with a cycle rating. Compare in 5kW batteries (5kW Lithium Battery).
