Knox Powerbase 10.5 51.2V 205Ah Lithium Battery Price in Pakistan

The Knox Powerbase 10.5 is a floor-standing 10kW-class battery. At 51.2V and 205Ah it stores 10.5 kWh. It uses LiFePO4 cells, and Knox rates it for 8,000+ cycles with a 5-year brand warranty. That cycle rating is higher than most 10kW batteries in our list, which are rated at 6,000+.

Backup time from full: about 29 hours on 2 fans, lights and a fridge (about 300W), about 19 hours on 4 fans, 8 LED lights and a TV (about 450W), and about 9 hours on a 1-ton inverter AC with a fan and lights (about 920W). A home with solar can fill it during the day and run an AC through most of the night. The lithium battery for AC page (Lithium Battery for AC) compares other AC-friendly sizes.

Compatibility: it is a 48V-class battery for 48V hybrid and off-grid inverters from Knox, Inverex, Growatt, Fronus and Deye, and fits 6kW to 10kW systems well. With a Knox inverter the match is easy; with other brands, set lithium or user mode, use the datasheet charge current and confirm BMS communication.

Installation: it stands on the floor, so plan a level, strong spot near the inverter with space around it for air. No IP rating is listed, so keep it indoors in a dry, shaded room. Use a DC breaker and thick cable sized for high current.

Life and warranty: 8,000+ cycles at one cycle a day is over 20 years of rated cycles on paper, and the 5-year brand warranty gives a clear support period. Our guide on how long lithium batteries last (How Long Does a Lithium Battery Last in Pakistan?) explains how heat and depth of discharge affect real life.

A practical tip: a floor battery should not sit directly on a damp floor. Place it on a level, dry surface and keep at least a hand's width of space at the sides for air. This simple step helps the cells stay cool in summer and supports the long cycle rating.

Powerbase 10.5 vs Rackwall 10.5: the Powerbase is floor-standing with 10.5 kWh, 8,000+ cycles and a 5-year warranty. The Rackwall is a rack or cabinet module with 10.24 kWh and 6,000+ cycles, and no published warranty term. If you do not need a rack, the Powerbase gives more published value. For bigger homes, the Powerbase 16.0 is the next step. Compare in 10kW batteries (10kW Lithium Battery).
