General Information
The Renogy Smart Lithium Iron Phosphate Battery enables the auto-balancing among parallel
connections and provides more flexibility for the battery bank configuration. The integrated
battery management system (BMS) not only protects the battery from various abnormal
conditions but monitors and manages the charging and discharging process. The state-of-the-art
battery cells ensures an extended cycle life and exceptional discharge performance. With built-in
intelligent self-heating, the battery is rechargeable even in low-temperature conditions.
Key Features
Auto-Balance
Connects multiple batteries in parallel safely with the auto-balancing function to meet the
power and energy requirements of different system setups.
Ultra-Safety
The battery management system (BMS) provides comprehensive protection to the battery
and manages the charging and discharging process.
Uncompromised Quality
The state-of-the-art battery cells ensure an exceptional lifespan of more than 4000 cycles
(80% DOD), up to 100A continuous discharge current, and a wide range of operating
temperatures.
Communication Port
The communication ports enable the communication between connected batteries, external
devices, and host computers.
Self-Heating
The intelligent self-heating feature keeps the battery charged in cold environments.

Before the installation and operation of the battery, it is recommended to have the following
equipment or tools available:
Safe and reliable installation requires trained and certified technicians. Therefore, the purpose
of this section is only to serve as a guideline as all scenarios cannot be covered.
DO NOT short-circuit the battery terminals. Doing so can cause current bursts and lead to
irreversible damage to the system and the battery.

Please verify the polarity before connecting the wiring. Reversing polarity can and will
destroy the battery.
Please use circuit breakers, fuses, or disconnects appropriately sized by a certified electri-
cian, licensed installers, or regional code authorities to protect all electrical equipment.
Please check for visible damage including cracks, dents, deformation, and other visible abnor-
malities. The top of the battery and terminal connections should be clean, free of dirt and
corrosion, and dry. If any problems are detected with the battery, please contact us for
assistance. Refer to the last page of the manual for contact information.
Inspection
Battery cables (sold separately) should be appropriately sized to handle the expected load.
Please refer to the following table for the ampacities of copper cables with different gauge
sizes.

The above values are from the NEC Table 310.15(B)16 for copper cables rated at 75°C
(167°F), operating at an ambient temperature of no more than 30°C (86°F). Lengths in excess
of 6 feet (1829 mm) may require heavier gauge cable to avoid excess voltage drop in under-
sized wiring.

08
To string multiple batteries in parallel, first
connect the Positive Terminals of the batteries to
each other. Then, connect the Negative Termi-
nals of the batteries to each other. Finally,
connect the Positive Terminal of the first battery
and the Negative Terminal of the last battery to
the system. This type of arrangement is used to
increase the overall battery capacity while
keeping the battery voltage the same.
To enable the communication between paralleled
batteries for the proper operation of the Renogy
Monitoring Screen or the Renogy Bluetooth
Module, connect the RS485 LINK Communica-
tion Ports of the former batteries to the RS485
UP Communication Ports of the latter ones using
CAT5 (or above) Ethernet straight through
cables (not included). The Renogy Monitoring
Screen or the Renogy Bluetooth Module should
be connected to the RS485 UP Communication
Port of the first battery.
Connecting Batteries in Banks
DO NOT string batteries in series. Doing so can cause catastrophic failure.
DO NOT string batteries with different chemistries, brands, models, rated capacities, or
nominal voltages in parallel.
Please avoid too high a voltage difference between paralleled batteries, despite the
auto-balancing function, to avoid triggering the over-current protection.
In parallel battery banks, the cables between each battery should be of equal length to
ensure that all batteries in the system can work equally together.
It is not recommended to connect more than 4 batteries in parallel if taking advantages of
the auto-balancing function.

Installation Environment
To ensure good contact between the cable lugs and the terminals, please use the appropriate
number of washers to allow for as much thread engagement as possible without bottoming out
the terminal bolt. The correct number of washers can be determined by hand-tightening the
terminal bolt with just the cable lug in place and observing the gap that is present. Use the
number of washers needed so that the washer stack is slightly larger than the observed gap.
It is important to ensure that the cable lug and the top surface of the terminal are in contact. The
washer(s) must be placed on top of the lug. Do not place the washer(s) between the battery
terminal and the cable lug as this can cause high resistance and excessive heating.
The battery should be installed in a clean, cool, and dry place, keeping water, oil, and dirt
away from the battery. The accumulation of these materials on the battery can cause current
leakage, resulting in self-discharge and a possible short-circuit. Sufficient air flow must be
provided to prevent excessive heat build-up and to minimize temperature variation between
the batteries.
Securing Cable Connections
Please secure all cable connections to the proper specification in order to ensure good
contact between the cable lugs and the terminals. Over-tightening cable connections can
cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
Please use an insulated Philips screwdriver to tighten the cable connections.
Please use the included Long Terminal Bolts when needed to secure multiple cable lugs on
a single battery terminal.
