1175Ah LFP Battery Cell: Specifications, Applications, and Buyer’s Guide

A 1175Ah LFP battery cell is a large-format lithium iron phosphate cell rated to deliver 1,175 ampere-hours under conditions defined by its manufacturer. Its high capacity can help reduce the number of cells needed in a battery system, but capacity alone does not determine whether it suits a project. Buyers also need to verify voltage, dimensions, current limits, operating conditions, safety documentation, and integration requirements against the actual cell datasheet.

Please visit our website for more information on this topic.

In this guide, we explain how to assess a 1175Ah cell for stationary storage and other potential applications, what information to request from a supplier, and how to compare commercial offers. We treat example calculations as illustrations rather than confirmed product specifications. For a HiTHIUM quotation, we recommend sharing the project’s technical requirements so our team can confirm available configurations and relevant documentation.

Who This Guide Is For

This guide is intended for battery system integrators, energy storage developers, EPC contractors, distributors, and procurement teams evaluating high-capacity LFP cells. It is useful when comparing cell-level offers or deciding whether a large cell format can simplify a system design. It is not a substitute for the manufacturer’s datasheet, system-level engineering, or applicable safety and compliance review.

What a 1175Ah LFP Cell Means

Capacity and energy are different specifications

Ampere-hours describe electric charge capacity; watt-hours describe energy. To estimate a cell’s nominal energy, multiply its rated capacity in ampere-hours by its nominal voltage in volts, then divide by 1,000 to obtain kilowatt-hours. For illustration only, if a 1175Ah cell has a nominal voltage of 3.2V, the calculation is 1,175Ah × 3.2V = 3,760Wh, or 3.76kWh.

The 3.2V value in that calculation is an example, not a confirmed specification for a particular cell. Use the nominal voltage stated in the supplier’s current datasheet, and do not treat calculated nominal energy as the usable energy of a complete battery system. Usable energy depends on factors such as permitted voltage range, operating limits, conversion losses, and system controls.

What LFP indicates

LFP refers to lithium iron phosphate chemistry. Buyers typically evaluate it in the context of cycle-life requirements, operating conditions, safety design, and total system cost rather than relying on chemistry name alone. Actual performance and suitability must be confirmed for the specific cell and the battery system in which it will operate.

Key Specifications to Verify

Cell capacity is only one line in a technical review. We recommend requesting a complete, revision-controlled datasheet and checking that the quoted cell configuration matches the version being evaluated. The following items help buyers compare offers consistently.

Applications and Cell-to-System Fit

Large-capacity LFP cells may be considered for stationary energy storage, including renewable energy integration, commercial and industrial storage, and grid-support projects. Their relevance depends on the project’s energy and power targets, installation footprint, operating profile, and the system integrator’s design. A 1175Ah rating by itself does not establish that a cell is suitable for a particular application.

For system planning, translate the project’s requirements into cell-level and pack-level constraints. Confirm how many cells are needed in series and parallel, what voltage range the power conversion system supports, and how the battery management system will monitor and protect the assembly. Also account for thermal design, fault isolation, mechanical restraint, maintenance access, and transport requirements.

You will get efficient and thoughtful service from HiTHIUM.

Use current calculations cautiously

Current depends on the cell’s permitted C-rate and the supplier’s operating limits. As a mathematical illustration, 0.5C applied to 1,175Ah equals 587.5A, but this is not a statement that a specific cell can safely charge or discharge at that current. Ask the supplier to confirm continuous and pulse limits, test conditions, and any restrictions before using a calculated value in system design.

Buyer Selection Framework

1. Define the project duty cycle

Start with the required usable energy, power, discharge duration, daily cycling pattern, and expected operating environment. Record whether the system prioritizes energy capacity, response power, footprint, or another project constraint. These requirements allow suppliers to respond to a defined application instead of offering a capacity figure without context.

2. Check integration and safety requirements

Have the engineering team review cell dimensions, terminal orientation, electrical limits, and proposed module architecture. Ask how the cell information supports system-level hazard analysis, monitoring, and protection design. Confirm which test reports, declarations, or certifications are available for the specific cell and intended market; do not assume that cell-level documents automatically establish compliance of a finished battery system.

3. Compare commercial terms on equal assumptions

Compare quotations only after confirming that they cover the same cell configuration, quantity, delivery terms, packaging, and documentation. Request clarity on minimum order quantity, sample availability, production lead time, payment terms, and warranty scope. These terms can vary by order size, destination, specification, and production schedule, so buyers should obtain project-specific written confirmation rather than rely on general estimates.

Pricing, MOQ, and Lead Time

There is no reliable universal price for a 1175Ah LFP cell without a confirmed specification and commercial scope. Price may depend on order volume, requested customization, quality documentation, packaging, shipping route, and delivery terms. Ask suppliers to itemize what the quotation includes and how long the offer remains valid.

Minimum order quantity and lead time should also be confirmed directly. For a pilot or qualification phase, ask whether sample quantities are available and whether sample cells match the production configuration under consideration. Align procurement timing with engineering validation, incoming inspection, and any project approval milestones.

Supplier Evaluation Checklist

• Request a current datasheet with a clear revision date and full electrical and mechanical specifications.
• Confirm capacity test conditions, operating limits, and cell-level traceability information.
• Ask what quality, safety, and market-specific documentation is available for the quoted configuration.
• Review sample and production availability, MOQ, lead time, warranty terms, and delivery scope in writing.
• Evaluate the supplier’s ability to answer engineering questions and support integration planning.
• Ensure the proposed cell and documentation fit the project’s system design and target market requirements.

Summary and Next Steps

A 1175Ah LFP cell may be a fit for projects seeking high cell-level capacity, but its rating is only a starting point. The right selection depends on verified voltage, current limits, physical design, operating conditions, system compatibility, documentation, and commercial terms. Treat energy and current calculations as preliminary until the supplier confirms the cell’s datasheet values and permitted operating range.

To evaluate a HiTHIUM solution, prepare your target application, required energy and power, operating conditions, system voltage, expected order quantity, destination market, and requested delivery window. Contact our team with these details to discuss the available cell configuration, technical documentation, sample or production options, and a project-specific quotation. We can then help you assess whether the proposed 1175Ah LFP cell aligns with your integration and procurement requirements.
