Inverex INV-LV 12V 200Ah IP21 Lithium Battery Price in Pakistan

The Inverex INV-LV 12V 200Ah IP21 keeps the same 12.8V voltage as the 100Ah model but doubles the capacity to 200Ah, so it stores 2.56 kWh. It uses LiFePO4 (lithium iron phosphate) chemistry, which is safer than NMC lithium, needs no water and gives about 90% usable depth of discharge. The IP21 rating means it is protected against fingers and dripping water only, so it is an indoor battery.

Backup time is the main reason to pick this one over the 100Ah. A 100W load (1 fan + 2 LED lights) runs for about 21 hours, and a router + CCTV load of about 30W runs for about 71 hours, which is roughly three days. For a family that only runs one fan and lights at night, this means the battery often lasts through the whole night with charge left. You can check other loads with the backup calculator (Battery Backup Calculator).

Which systems does it suit? Only 12V ones: a 12V home UPS, a 12V solar charge controller, or a small 12V inverter. Because the battery is large for a 12V system, check that your UPS or charger can push enough charging current to fill 200Ah in your outage gap. A small UPS charger may need many hours. If your inverter is 24V or 48V, this is the wrong battery; see the guide on lithium battery inverter compatibility (Which Lithium Battery Works With My Inverter?).

Installation: it is a box battery that sits on the floor or a rack. Keep it indoors because of IP21, away from rain and direct sun, and use thick cables. At 12V, every 100W of load draws around 8A, so thin wires get hot.

Life and warranty: Inverex does not publish a cycle count or warranty period for this model in our data. Ask before ordering and check the datasheet.

A practical tip: if you use this battery with solar, set the charge controller to the LiFePO4 profile, not the flooded or gel profile. The wrong profile is the most common reason a 12V lithium battery never shows full charge.

Who is it for? Homes and shops already on a 12V UPS who want long backup without buying a new inverter. If you are building a new system, a 24V battery like the Inverex INV-2.5 Power Wall stores the same 2.56 kWh at a higher voltage with less current, so compare it in all 24V batteries (24V Lithium Battery) or all 200Ah batteries (200Ah Lithium Battery).
