1.2 Safety Precautions
Operators and installers are responsible for familiarizing themselves with the contents of this manual and
note all warnings before operating. The battery operates under possible dangerous voltages and AIMS
Power strongly recommends all installations be performed by qualified and trained professionals.
Over-voltages or wrong wiring can damage the battery pack and cause deflagration, which can be
extremely dangerous. Any damage to the case may lead to a leakage of electrolyte or flammable gas. Do
not use if the case is damaged. Avoid installing the battery pack where flammable materials are stored. Do
not install in places where explosive gas or chemicals are present. Check the surroundings and make sure
all pipes and fittings don’t contain dangerous gasses, chemicals or water.
Battery Pack is not user serviceable.
1.3 Battery Handling Guide
Do not expose battery to open flame
Do not place the battery near anything flammable. It may lead to fire or explosion.
Do not expose or place near water sources like downspouts or sprinklers. Electric shock may occur.
Do not store battery in a place exposed to direct sunlight
Store and operate in a cool, dry, well ventilated area
Store the battery on a flat surface
Keep out of reach of children and animals
Keep dust and dirt away from battery
Do not disconnect, disassemble or repair by unqualified personnel. Service must be made by
qualified personnel only.
Do not drop, cut, puncture or penetrate the battery. It may cause leakage of electrolyte or fire.
Do not touch if liquid is spilled on the product. There is a risk of electric shock. Use insulated gloves.
Do not step on the battery. This could damage the battery.
Do not place any foreign objects on the top of the battery
Do not install the battery pack upside down
Ensure polarity connection is correct. Do not reverse positive and negative wires to terminal block
Do not attempt to charge or discharge a damaged battery
Keep battery out of extreme weather elements. Store and operate indoors.
Do not connect any AC conductors or photo-voltaic conductors directly to the battery pack
Remove all jewelry during handling
Do not smoke near the battery
Do not use while on medication
Do not drop tools or anything sharp on the battery. Shock can occur.
1.4Response to Emergency Situations
The battery consists of multiple fused batteries and a sophisticated BMS that are designed to prevent
hazards resulting from failure. However, we cannot guarantee their absolute safety if battery is mishandled.
If a user happens to be exposed to internal materials of the battery cell due to damage to the outer casing,
the following actions are recommended.
Inhalation: leave the contaminated area immediately and seek medical attention
Chemical eye burn: rinse eyes with running water for 15 minutes and seek medical attention
Contact with skin: wash the contacted area with soap thoroughly and seek medical attention
Ingestion: seek medical attention.

Fire
Use a foam extinguisher, CO2, ABC dry chemical, powdered graphite, copper powder or soda (sodium
carbonate).
1.5 Users / Operators
•Users of this battery should understand the functional principles and operation of on-grid and off-
grid (backup) systems
•Knowledge of the dangers and risks associated with installing and using electrical devices at
possible dangerous voltages is the responsibility of the user not AIMS Power
•Electrical certification and/or training is strongly recommended
Make sure all power is off and wires are disconnected when maintaining/servicing the battery
1.6 Recycling & Disposal
The U.S. Environmental Protection Agency (EPA) does not regulate the disposal of batteries in small
quantities; large quantities are regulated under the Universal rules of Hazardous Waste regulations (40
CFR PART 273). While there are no federal regulations for disposal of lithium batteries, individual states or
localities have established their own guidelines for battery disposal and should be contacted for any
disposal guidelines that they may have.
Batteries for commercial use should be in a discharged condition prior to their disposal. Generally, a
primary lithium cell is considered to be discharged once its voltage reaches 2 volts or less under a current
of C/100 (C is the rated capacity of the battery in ampere-hours).
Do not dispose with regular household trash. Contact local recycling or waste companies.

4 Weight Boxed 105kg / 231 lb
2.7 Transportation and Storage
Based on the characteristics of the cell, the proper environment for transportation of a LiFePO4 battery
pack must be followed to protect the battery. Battery should be stored at -20℃～35℃/ -4°～95°F in a dry,
clean, cool, shaded, and well-ventilated area. The battery should be charged to 45~55% SOC during
transportation and stored at 60% SOC.
When in transport, it should be covered to avoid sunlight, and handled with care during loading and
unloading. The outer box is designed for many types of transport. Direct moisture should be avoided during
transportation.
Do not store in direct sunlight or damp/wet environments. Harmful gases, as well as flammable and
explosive products and corrosive chemicals should not be stored near the battery. Check all pipes for
possible water or chemical leaks. The battery should be stored 8” off the ground and 20” away from the
wall, window, or the air inlet. For storage periods longer than 3 months the battery should be charged once,
and not stored for more than 6 months without cycling the battery. For batteries stored longer than 1 year
without cycling or maintenance, the battery must be carefully tested before use.

3 Installation
3.1 Location
•There must be no flammable or explosive materials near the battery
•The recommended ambient temperature should be -10° ~ 45°C /14°~113°F
•Operating temperature of -20° ~ 65°C /-4°~149°F
•Install and store indoors – keep out of wind, snow, rain and direct sun
•The structure and/or support for the battery should be designed to withstand earthquakes
•Waterproof and properly ventilated area
•Install battery on a flat wall, surface or heavy-duty cabinet. Use proper supports, brackets and/or
straps to handle the weight of the battery.
•Keep battery away from passerbys
CAUTION!
If the ambient temperature is outside of the operating range, the battery pack may stop operating to protect
the internal components. The optimal temperature range for the battery pack to operate is from 10°C to
30°C / 50°F to 86°F. Frequent exposure to harsh temperatures may deteriorate the performance and
overall life of the battery and will void the warranty.
3.2 Clearance
Recommended clearance is 12” on
top, left and right sides of the battery
and 24” on the bottom to allow for
proper ventilation and air flow.

3.3 Tools & Safety
Tools
The following tools are required to install the battery pack:
Level Screwdriver M8 & M10 Torque wrench
Drill Pencil or Marker
Safety gear for personal protection
It is recommended to wear the following safety gear when handling the battery pack.
Insulated gloves Safety goggles Safety shoes

3.6 Battery Pack Installation
CAUTION!
Make sure the DC load is in the off position and any disconnects (if used) are turned off before connecting
the power cable to the battery pack.
NOTE!
USE PROPER BRACKETS, SUPPORTS, AND/OR STRAPS TO HANDLE THE WEIGHT OF
THE BATTERY. WELL VENTILATED, HEAVY DUTY BATTERY CABINET IS RECOMMENDED.
3.7 DC Wiring
AIMS Power recommends keeping the battery pack as close as possible to the DC load. Refer to the below
chart for minimum wire size. If the length of cable is longer than 4 feet, use the next larger size of cable.
Model DC Output Voltage Typical Wire
Gauge
LFP24V400A 25.6Vdc 4/0 AWG (4 AWT)
LFP48V200A 51.2Vdc 1/0 AWG (1 AWT)
*NOTE: THE CABLE USED MUST BE RATED FOR A MINIMUM OF 240a FOR 48V 200A AND 360A
FOR 24V 400A.
Performance is improved by using a thicker cable and shorter runs. If unsure, round up and keep the length
as short as possible.
For wiring configurations for your specific system, please contact AIMS Power for more information.
WARNING
The torque rating range for DC terminal is 19.8NM-24.6NM, and the suggested torque rating is 22.5NM.
Over torqueing may cause the bolt to break.
WARNING
Max batteries connected in parallel is up to 10 batteries. Only use identical batteries. All cables
must be the same length and size.
DO NOT WIRE IN SERIES!
