Ziewnic Li-Wall 2.56kWh Lithium Ion Battery Power Bank 25.6V 100AH

Ziewnic Li-Wall 2.56kWh Lithium Ion Battery Power Bank 25.6V 100AH is listed with 13 published specifications from Ziewnic, including charge voltage of 27.6V, battery voltage of 25.6V, IP degree of protection of 1P21 and storage temperature of 0°C~30°C. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a battery, the figures that matter most are usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Ziewnic Li-Wall 2.56kWh Lithium Ion Battery Power Bank 25.6V 100AH is listed at ₨ 146,000 (PKR). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Ziewnic locally before ordering.
