The AIMS Power 24V 400A Industrial Grade Lithium Iron Phosphate Battery Puts 10.2 kWh of Long-Life Storage in One Battery

The AIMS Power 24V 400A Industrial Grade Lithium Iron Phosphate Battery delivers 400 amp hours at 24 volts, about 10.2 kWh of energy, in a single industrial-grade LiFePO4 battery. That large capacity in one unit can eliminate the need for multiple smaller batteries. Compared to other battery technologies, AIMS Power says it delivers large amounts of power at half the weight with up to 8 times more cycles and no memory effect. A built-in Battery Management System, automatic cell balancing, and RS485 and CAN communication ports make it a strong foundation for 24 volt off-grid, backup, and industrial power systems.


AIMS Power 24V 400A Industrial Grade Lithium Iron Phosphate Battery Features

Up to 6000 Cycles for Long Service Life

AIMS Power rates this battery at 3500 cycles at 80% depth of discharge and 6000 cycles at 60% depth of discharge, roughly 8 times more cycles than other battery technologies.

Built-In Battery Management System for Safety and Performance

The BMS maintains voltage, current, and temperature, enables maximum charging capacity for faster charging, and protects against short circuits, overcharge, over-discharge, and low voltage with automatic shutdown. BMS temperature protection and reverse polarity protection add further safeguards.

Automatic Cell Balancing So the Battery Stays Healthy

Automatic cell balancing maintains individual cell integrity, and the battery requires almost no maintenance.

High Output Current for Inverters

Designed for systems that need large amounts of power at 24 volts, the battery delivers high output current for inverters and inverter chargers.

Monitoring and Easy Expansion

A front-panel LED displays state of charge, and RS485 and CAN ports allow monitoring with desktop software (interface not included). Connect up to 10 batteries in parallel, using the included 41 inch parallel cables.

Flexible, Clean Installation

Mount it in any orientation. There is no venting or gassing, and it includes a power switch, 3/8 inch terminals, and terminal covers.


Real-World Applications

Off-grid homes and cabins. Store solar energy in a high-capacity 24 volt bank.

Home and business backup. Pair with a 24 volt inverter charger for extended outage protection.

Industrial applications. Power equipment that needs large amounts of energy at 24 volts.

Large mobile systems. Provide substantial capacity for 24 volt vehicles or vessels where space and weight allow.


How It Compares to Common Alternatives

Versus multiple smaller batteries. One 400 amp hour battery replaces several smaller units, simplifying wiring and monitoring.

Versus AGM or flooded lead-acid. LiFePO4 offers far more cycles, no maintenance, no gassing, and roughly half the weight for the same capacity, according to AIMS Power.

Versus lighter lithium batteries. AIMS Power notes that lithium requires a certain density to deliver full rated capacity, and encourages buyers to compare weights carefully when evaluating capacity claims.


Is This 24V Lithium Battery the Right Fit

  • System voltage. It is a 24 volt battery, so pair it with 24 volt inverters, chargers, and charge controllers.
  • Weight and size. At 214 pounds and 32" x 21" x 7", plan for handling equipment and a sturdy location.
  • Monitoring. RS485 and CAN ports are built in, but the interface is not included.
  • Expansion. Up to 10 batteries can be connected in parallel.

This may be a good fit if

  • You need large, long-life 24 volt storage in a single battery
  • You are building or upgrading an off-grid or backup system
  • You want BMS protection and state of charge monitoring
  • You want room to expand with additional batteries

Common Questions

How Many Batteries Can I Connect Together?

Up to 10 batteries in parallel, according to AIMS Power. Parallel connection cables are included.

Can I Monitor It Remotely?

It has RS485 and CAN ports for desktop monitoring software. The interface is not included.

Does It Need Ventilation?

AIMS Power notes there is no venting or gassing, and it can be mounted in any orientation.

What Warranty Does It Carry?

AIMS Power lithium batteries include a lifetime warranty covering manufacturing defects for up to 3,500 cycles, assessed by the BMS and AIMS Power, for units sold by AIMS Power or its authorized resellers.
