How to read this datasheet

Detailed specifications for 12V 200Ah LiFePO4 Deep Cycle Lithium Battery have not been published yet. ACOPOWER lists this battery in the Batteries, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a battery, the figures that matter most are 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, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid. 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.

Choosing a battery: the checks that matter

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.

Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.
Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.

Common mistakes

Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.

Price and availability

12V 200Ah LiFePO4 Deep Cycle Lithium Battery is listed at A$ 1,058 (AUD). 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 ACOPOWER locally before ordering.

12V 200Ah LiFePO4 Deep Cycle Lithium Battery — frequently asked questions

How much does 12V 200Ah LiFePO4 Deep Cycle Lithium Battery cost?

12V 200Ah LiFePO4 Deep Cycle Lithium Battery is listed at A$ 1,058 (AUD). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes 12V 200Ah LiFePO4 Deep Cycle Lithium Battery?

12V 200Ah LiFePO4 Deep Cycle Lithium Battery is a ACOPOWER product, listed under batteries with model reference HY-Li200Ah. The ACOPOWER brand page lists the rest of its range so you can compare across the catalogue.

Is 12V 200Ah LiFePO4 Deep Cycle Lithium Battery right for my system?

That depends on what it has to connect to. For a battery, check 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 and continuous charge and discharge current, which limits how much power you can draw from the pack against the rest of your equipment before price enters the decision. Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.

Where can I buy 12V 200Ah LiFePO4 Deep Cycle Lithium Battery?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
