The AIMS Power 24V 400Ah LiFePO4 Industrial Grade Battery is a high-capacity lithium iron phosphate battery designed for 24V battery systems that require large amounts of stored power. With 25.6V nominal voltage, 400Ah rated capacity, and 10.24 kWh rated energy, this battery provides a consolidated lithium storage option for compatible inverter and backup power systems. It includes a built-in Battery Management System, automatic cell balancing, low and high voltage protection, overcharge protection, over-discharge protection, short circuit protection, reverse polarity protection, and temperature protection. RS485 and CAN communication ports support PC monitoring, while front-mounted LED indicators display state-of-charge status. This battery is designed for indoor wall, flat-surface, or heavy-duty cabinet mounting with proper support, ventilation, cabling, and system design.
This AIMS Power industrial lithium battery provides 400Ah capacity and 10.24 kWh rated energy for properly designed 24V battery systems. Its high-capacity format helps reduce the need for multiple smaller batteries while keeping system design focused around one compatible 24V LiFePO4 battery platform.
The integrated Battery Management System monitors and manages voltage, current, temperature, and individual cell protection during charge and discharge. Supported protections include short circuit protection, automatic low-voltage shutdown, overcharge protection, over-discharge protection, reverse polarity protection, and BMS temperature protection.
The battery includes RS485 and CAN communication ports for monitoring through compatible desktop software. Supported monitoring visibility includes state of charge, voltage, current, cycles, capacity, running status, cell balancing, cell voltage, and internal cell temperature.
The AIMS manual specifies indoor installation on a flat wall, surface, or heavy-duty cabinet using proper supports, brackets, or straps for the battery weight. Up to 10 identical batteries may be connected in parallel, but the manual states not to wire these batteries in series.

This 24V 400Ah industrial LiFePO4 battery is designed for properly engineered battery systems that require high-capacity lithium storage, BMS protection, RS485/CAN monitoring, and indoor installation with correct cabling and support.
With 10.24 kWh rated energy, automatic cell balancing, front LED state-of-charge indicators, and up to 10-battery parallel support, the LFP24V400A supports compatible 24V inverter and stored-power system designs.
