Fronus Diamond 25.6V 100Ah Lithium Battery Price in Pakistan

The Diamond is a 25.6V, 100Ah lithium iron phosphate battery built to hang on the wall. Multiply the two numbers and you get 2.56 kWh, the size most people call a "2.5kW lithium battery". The 25.6V figure is the nominal voltage of a LiFePO4 pack made for 24V systems, so it is the standard lithium replacement for a UPS that used to run on two 12V lead-acid batteries in series.

Fronus sells two 24V wall batteries of this exact size: the Diamond and the Titan 24V 100Ah. On our spec sheet the capacity, voltage and mounting are the same. The difference we can confirm is on paper: the Titan lists a 6,000+ cycle rating, while the Diamond's cycle figure has not been given to us. If cycle life matters to you, for example with daily solar charging or long night outages, ask for the Diamond datasheet or pick the Titan. If both are in stock, compare the live price and warranty terms of each.

Backup from a full charge, using about 90% usable depth of discharge and normal inverter losses: - 2 fans + lights + fridge (about 300W): about 7 hours - 4 fans + 8 LED lights + TV (about 450W): about 5 hours - 1-ton inverter AC + fan + lights (about 920W): about 2 hours

An old UPS with a high idle draw will give a little less than these numbers. Connect the Diamond to a 24V UPS, a 24V off-grid solar inverter or a 24V solar charge controller that has a lithium profile. Do not connect it to a 48V hybrid inverter. Mount it indoors on a solid wall out of direct sun. Our listing shows no IP rating for the case, so keep it away from rain, kitchens and washing areas. Read the inverter compatibility guide (Which Lithium Battery Works With My Inverter?) before you remove your old lead-acid batteries, because charge voltage and cut-off settings must change.

Fronus has not published a fixed warranty period for the Diamond to us, so treat it as "ask before ordering" and get the terms written on the invoice. Like any LiFePO4 pack, it needs no water and has no acid fumes, so it can live inside the house. It suits buyers who want a quiet, maintenance-free 24V backup of this size. If 2.56 kWh is too small for your load, see all 24V batteries (24V Lithium Battery) or the full Fronus range (Fronus Lithium Battery prices).
