200Ah Lithium Battery Price in Pakistan

200Ah lithium battery models

• 12V 200Ah (2.56 kWh): Inverex INV-LV 12V 200Ah IP21.
• 24V 200Ah (5.12 kWh): Itel IPW-25200 and Max Power MP-5000 Pro, both floor units.
• 48V 200Ah (10.24 kWh): Knox Rackwall 10.5, Itel IPL-51200, Narada NESR48200, Nimbess Flyer 10.24 (5-year warranty), Oliter Nebula 10.24, Dyness Powerbox Pro IP65 and Sunsynk 10.24kWh IP65 (both 10-year warranty).

All are LiFePO4 with a built-in BMS.

What each 200Ah runs

• 12V 200Ah: 100W for about 21 hours, or 300W for about 7 hours.
• 24V 200Ah: 500W for about 8 hours, or 1,000W for about 4 hours if the inverter can carry it.
• 48V 200Ah: a 1 ton inverter AC for about 8.5 hours, or two ACs at 2,000W for about 4 hours.

See the backup calculator (Battery Backup Calculator).

Which 200Ah to choose

If you have a 12V UPS and want long backup for fans and lights, the 12V 200Ah doubles a standard 100Ah. If you have a 24V UPS or 24V solar inverter, the 24V 200Ah gives 5kW-class storage without changing the inverter. If you have a 48V hybrid inverter, a 48V 200Ah is a 10kW battery; see 10kW batteries (10kW Lithium Battery).

One 200Ah or two 100Ah?

One 200Ah pack has one BMS and simpler wiring. Two 100Ah packs in parallel give the same energy and can be bought in stages, but need matching models and a UPS or inverter that supports parallel lithium. Check the IP rating too: the Inverex 12V 200Ah is IP21 (indoor), while the Dyness and Sunsynk 48V models are IP65.

Buying checklist for a 200Ah lithium battery

A 200Ah battery comes in three voltages, so check these points before you order.

• Match the battery voltage to your inverter or UPS.
• Check the cycle rating and warranty years; where a value is missing, ask or check the datasheet.
• Keep the invoice and serial number for any warranty claim.
• Set the charge voltage and cut-off from the datasheet, not from memory.
• Install in a cool, ventilated spot, away from direct sun.

Compare by kWh, not by Ah alone. A 12V 200Ah and a 48V 200Ah share the Ah number, but the 48V pack stores four times the energy. For a 24V UPS, check the charge current: a 200Ah pack takes longer to fill on a small charger.
