Introduction
Introduction
Introduction
Meet the next era of energy storage system with Renogy 12V 400Ah REGO Lithium Iron
Phosphate Battery. With a large capacity of more than 5KWh, the battery is designed to run
loads for extended periods of time. Manufactured with top grade cells, the battery provides an
exceptional lifespan of more than 3800 cycles (80% DOD), a continuous discharge current up
to 350A for heavy loads, and a continuous charge current up to 300A for 1.5-hour fast charging.
The integrated battery cables and Anderson connector significantly simplify the wiring, reduce
the risk of short circuit, misconnection, and connection failure, and allow for quick connection
and disconnection. The sophisticated battery management system (BMS) offers up to 60 types
of warnings and protections, enables precise cell balancing, and stores up to 150 event records.
The built-in heater operates automatically at low temperatures to keep the battery charging.
The straightforward LED indicators visualize the battery level, battery status, and heater status.
The on-board Bluetooth module ensures real-time monitoring on DC Home app and compatible
monitoring devices. The RV-C protocol compatibility allows for complete system integration,
featuring better charging experience, safer operation, and more customizable settings to
extend the lifespan of the battery. The waterproof die cast aluminum housing and stringent road
load tests ensure that the battery can deliver extreme performance even under the harshest
conditions including wet environments and mechanical vibrations.

Installation
Inspection
Inspect the battery for any visible damages including cracks,
dents, deformation, and other visible abnormalities before
installation. The connector contacts shall be dry, clean, and free
of any dirt and corrosion.
WARNIN
G
zDO NOT use the battery if it appears damaged.
Environment
Ensure that the installation environment is clean, cool, and well-ventilated. Keep the battery
away from oil and dirt. The accumulation of these substances can cause current leakage,
resulting in self-discharge and a possible short circuit. Avoid restricting airflow by tightly packing
batteries together. Allow at least 0.5 inches (12.7 mm) of space between the batteries for
efficient heat dissipation and minimal battery temperature variations. Safe operation requires
environment temperatures between -4°F (-20°C) and 122°F (50°C). The recommended
operating environment temperature range is 59°F (15°C) and 86°F (30°C).
Placement
Place the battery upright or horizontally on the long side.

Communication
Communication
The communication connection is optional. It allows the battery to communicate with other
REGO devices and monitoring devices, enabling safe operation, smart control, remote
monitoring, and programmable settings.
Inter-Device Communication
Depending on the installation condition, the communication connections between the battery
and other REGO devices can be established with backbone or daisy chain topology. The inter-
device communication allows the battery to dynamically adjust the charging profile for an optimal
