Introduction
The Renogy Pro Series 12.8V 100Ah Smart Lithium Iron Phosphate Battery adopts a proprietary
battery housing material in a smaller size for your RV application.
Weighing only half of the lead-acid counterparts, the battery can be safely discharged to 100%
Depth of Discharge (DOD), delivering twice the energy. Manufactured with automotive grade
battery cells, the battery features the highest safety standards and an extended 5000+ cycle life.
In addition, the smart Battery Management System (BMS) provides comprehensive protection to
the battery.
Key Features
zUnparalleled Performance
Features a greater energy density, a deeper discharge capability, a higher round-trip
efficiency, and a faster charging speed in a smaller size over counterparts in the market.
zUncompromising Quality
Ensures an exceptional lifespan with more than 5000 cycles (80% DOD), a continuous charge
or discharge current of 100A, and a wide range of operating temperatures with the automotive
grade battery cells.
zReliable Protection Mechanisms
Designed with a sturdy internal structure for RV use, and includes more than 60 protections
and alarms through the smart battery management system.
zReal-time Monitoring Through DC Home App
You can easily get the battery information through the DC Home App at any time.
zIntelligent Self-Heating Function & More Stable Performance
The built-in heater operates automatically at low temperatures to keep the battery charging,
assuring charging performance at low temperature and increasing battery lifespan.
zActive Safety Protection with Self-Control Fuse
Different from ordinary passive fuses, the self-control fuse can effectively prevent battery
overcurrent and overvoltage failures.
zBest-in-Class Capacity and Easy Expansion
The battery provides a maximum capacity of more than 105Ah for a longer-lasting application.
It supports up to 8 batteries in parallel, delivering a maximum of 12.8V 800Ah at 10.24kWh.

How to Size Battery Adapter Cables?
Use appropriately sized Battery Adapter Cables (sold separately) based on expected load. Refer to
the table below for copper cable ampacities with different gauge sizes.
Cable Gauge Size Ampacity Cable Gauge Size Ampacity
14 AWG (2.08 mm²) 35A 2 AWG (33.6 mm²) 190A
12 AWG (3.31 mm²) 40A 1 AWG (42.4 mm²) 220A
10 AWG (5.25 mm²) 55A 1/0 AWG (53.5 mm²) 260A
8 AWG (8.36 mm²) 80A 2/0 AWG (67.4 mm²) 300A
6 AWG (13.3 mm²) 105A 4/0 AWG (107 mm²) 405A
4 AWG (21.1 mm²) 140A
The above values are from the NEC Table 310.17 for copper cables rated at 194°F (90°C),
operating at an ambient temperature of no more than 86°F (30°C). Cables longer than
13 feet (4000 mm) may require thicker gauge wires to prevent excessive voltage drop in
undersized wiring.

Step 1. Plan a Mounting Site
For optimal battery performance, it is recommended to install the battery in a clean, cool, and dry
location, free from any accumulation of water, oil, or dirt. Accumulation of such materials on the
battery can lead to current leakage, self-discharge, and even short-circuiting.
KEEP DRY FRAGILE VENTILATION

Discharge: -4°F–140°F / -20°C–60°C

Sufficient airflow must be provided to prevent excessive heat build-up and to minimize
temperature variation between the connected batteries.

Insulating Gloves
Step 3. Check the Battery
Inspect the battery for any visible damage including cracks, dents, deformation, and other visible
abnormalities. All connector contacts shall be clean, free of dirt and corrosion, and dry.
Do not touch the exposed electrolyte or powder if the battery is damaged.
If uncovered electrolyte or powder contacts your skin or eyes, flush it out immediately with
plenty of clean water and seek medical attention.

Ensure the cable lug and the top surface of the terminal are in contact, and place the
washers on top of the lug. Do not place the washers between the battery terminal and the
cable lug to avoid high resistance and excessive heating.
Avoid short-circuiting the battery terminals to prevent irreversible damage to the system
and battery caused by current bursts.
Verify polarity before wiring to avoid irreversible battery damage due to polarity reversal.
Do not touch the positive and negative terminals of the battery with your hands.
To ensure safe and reliable operation of the system, please follow the torque specifications
recommended by the manufacturer when securing cable connections. Over-tightening
can result in terminal breakage, while loose connections can lead to terminal meltdown or
fire. When securing multiple cable lugs on a single battery terminal, use the included Long
Terminal Bolts.
Step 5. Connect the Battery to Other Devices
Please use circuit breakers, fuses, or disconnects appropriately sized by a certified
electrician, licensed installers, or regional code authorities to protect all electrical
equipment.
