Knox Powerwall 4.15 25.6V 100Ah Lithium Battery Price in Pakistan

The Knox Powerwall 4.15 is often assumed to be a 4 kWh battery because of its name, but our spec data lists it as 25.6V and 100Ah, which is 2.56 kWh. If you are choosing it for more backup than a Powerwall 3.0 or 3.1, please confirm the label or datasheet before ordering. It uses LiFePO4 cells and is a wall-mounted unit. Our data does not list a cycle count, IP rating or warranty period for it.

Backup time from full, based on 2.56 kWh: about 7 hours on 2 fans, lights and a fridge (about 300W), about 5 hours on 4 fans, 8 LED lights and a TV (about 450W), and about 2 hours on a 1-ton inverter AC with a fan and lights (about 920W). The lithium battery backup calculator (Battery Backup Calculator) lets you test your own load.

Compatibility: it is a 24V-class battery for 24V inverters and UPS systems from Knox, Inverex, Fronus and others. It is not for 12V UPS units or 48V hybrid inverters. Use lithium or user battery mode and match the charge settings to the datasheet; see the inverter compatibility guide (Which Lithium Battery Works With My Inverter?).

Installation: mount it on a solid wall indoors close to the inverter. With no IP rating listed, keep it dry, shaded and away from cooking heat. Fit a DC breaker and use proper lugs.

Life and warranty: not published in our data. As LiFePO4 it needs no water and handles deep daily use far better than lead-acid, but ask us what Knox offers on this model before you order.

A buying tip: because the 4.15 and 3.1 look so alike on paper, ask the seller to show the label photo with voltage, Ah and serial before dispatch. That way you know exactly which capacity you are getting and can register the battery with Knox for any after-sales support.

How it fits in the Knox 24V line-up: the 3.0 LCD and 3.1 carry a published 6,000+ cycle rating at the same 2.56 kWh, so on paper they give you more information for the same backup. Choose the 4.15 if it suits your wall space or local service, and confirm the specs. Compare all 24V batteries (24V Lithium Battery) and the full Knox range (Knox Lithium Battery prices).
