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.

2 Product Introduction
2.1 General Information
This battery is packed with power and delivers efficient power for battery systems requiring large amounts
of power at 24 or 48 Volt. The AIMS Power 24V 400 amp or 48V 200 amp has large amp capacity in one
battery and eliminates the need for multiple batteries without losing amperage. Compared to other battery
technologies, this battery delivers large amounts of power, at half the weight and provides up to 8 times
more cycles. Loaded with automatic safety features, such as a Battery Management System (BMS), which
maintains individual cell integrity, low and high voltage protections and temperature management. The
battery also uses automatic cell balancing, requires almost no maintenance and includes RS485 and CAN
monitoring.
2.2 Product Features
Up to 8 times more cycles compared to other battery technologies
3500 cycles at 80% DoD, 6000 cycles at 60% DoD
Short circuit protection
Automatic low voltage shutdown
Over charge protection
Over discharge protection
Mount in any orientation
Multiple batteries: 10 batteries in parallel maximum
Automatic cell balancing
High output current for inverters
Battery status LED located on the front of the battery displays SOC percentage
RS485 & CAN ports
Power switch & Remote ON/OFF
Built in Battery Management System (BMS)
RoHS compliant
IP21
Reverse polarity protection (caution)
No venting or gassing
BMS temperature protection
Battery Management System. The built in BMS is a central hub inside the battery that maintains constant
voltage, current and temperature. The BMS allows for maximum charging capacity for faster charging and
efficient discharging. It also communicates with the desktop monitoring software via the RS485 or CAN
port.
