General Information
The Renogy Smart Lithium Iron Phosphate Battery is the perfect option for off-grid energy
storage systems. The 48V nominal voltage ensures low heat generation and high efficiency
during high power transmission. The modular design easily scales to meet a range of
configurations—making it simple to tailor your energy requirements to specific projects. The
battery meets the highest safety standards and has an exceptional lifecycle, optimized with
proprietary manufacturing processes and cell architecture. The state-of-the-art battery
management system (BMS) enables comprehensive protection features and real-time
monitoring. With built-in intelligent self-heating, the battery is rechargeable even in
low-temperature conditions.
The battery management system (BMS) and high-performance dual-processors provide
comprehensive protection features and real-time monitoring.
Easily connect multiple batteries in parallel with the auto-balancing function to meet the
power and energy requirements of different system setups.

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.
The Long Terminal Bolts (M8 x 1 x 20) are used to secure multiple cable lugs on a single
battery terminal.

Please verify the polarity before connecting wiring. Reversing polarity can and will destroy
the battery.
Please use circuit breakers, fuses, or disconnects appropriately sized by a certified
electrician, licensed installers, or regional code authorities to protect all electrical
equipment.
Please check for visible damage including cracks, dents, deformation, and other visible
abnormalities. 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 tothe 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.
Cable Sizing
DO NOT short-circuit the battery terminals. Doing so can cause current bursts and lead to
irreversible damage to the system and the battery.

The above values are from 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 undersized wiring.
To string multiple batteries in parallel, first
connect the Positive Terminals of the
batteries to each other. Then, connect the
Negative Terminals of the batteries to
each other. Finally, connect the Positive
Terminal of the first battery and the
Negative Terminals of the last battery to
the system. This type of arrangement is
used to increase the overall battery capac-
ity while keeping the voltage the same.
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 8 batteries in parallel if taking advantages of
the auto-balancing function.
Connecting Batteries in Banks
Copper Cable
Communication
Cable
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 Communication Ports of the
former batteries to the RS485 UP Commu-
nication 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 tothe RS485 UP Communication Port of the first battery.
Securing Cable Connections
Installation Environment
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.
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.
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.
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.
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.
