AIMS Power’s 12 Volt LiFePO4 battery product line has a battery for every application. The LiFePO 4 batteries maintain a constant output voltage, providing more efficient power. This allows the cell to deliver virtually full power until it is discharged, and it can greatly simplify or even eliminate the need for voltage regulation circuitry. The battery has a much longer cycle life capacity and is easier to maintain compared to other battery technologies. The LiFePO 4 technology has better thermal and chemical stability, which improves battery safety, and is packed with power in a small and lightweight footprint. Easily uses the same space as your existing 12V battery and replaces lead-acid, AGM, or Gel battery applications in RVs, boats, commercial vehicles, off-grid backup power, and much more. Not intended to replace starting batteries. \

BMS FUNCTION

Circuit Protection: The battery includes a BMS (Battery Management System) to protect the battery from overcharging, over-discharging, over the drain, and short circuit, resulting in overall longer battery life. The BMS also protects the battery from exploding and catching fire. Includes thermal safety fusing, cell balancing, CID, and fault recovery.  Bluetooth monitoring is available.

WARNINGS

Lithium-ion cells and battery packs may get hot, explode or ignite and cause serious injury if exposed to extreme conditions. Be sure to follow the safety warnings listed below:

• Do not connect the positive terminal and negative terminal of the battery to each other with any metal object (such as wire)
• Only use approved LiFePO 4 battery chargers
• Do not carry a battery while wearing necklaces, rings, bracelets, hairpins or other metal objects
• Do not puncture, strike, or step on the battery
• Do not expose the battery to water or saltwater, or allow the battery to get wet
• Do not use LiFePO4 battery with any other types of batteries
• Do not use as starting battery of the vehicle
• Do not connect to an alternator or non-smart charging system
• Do not smoke around or near the battery
• Be careful not to drop heavy tools on the battery
• Keep away from children.

Do not place the battery in or near the fire, on stoves, or in other high- temperature locations. Do not place the battery in direct sunlight, or use/store the battery inside cars in hot weather. Doing so may cause the battery to generate heat, explode or ignite. Using the battery in this manner may also result in a loss of performance and a shortened
life expectancy.
Do not disassemble or modify the battery. The battery contains safety and protection devices, which, if damaged, may cause the battery to generate heat, explode or ignite.
Immediately discontinue use of the battery if, while using, charging or storing the battery, the battery emits an unusual smell, feels hot, changes color or shape, or appears abnormal in any way. Contact AIMS Power if any of these situations occur.
Do not place the battery in a microwave oven, high-pressure container or on induction cookware.
Inspect the battery for any damage, cracks, corrosion on terminals. DO NOT USE if you find any damage to the battery.
Use good quality and proper size cables for your application.

*The internal Battery Management System is complex and provides extra safety features. Note the max drain per battery specifications.

CHARGING

Only use battery chargers made for LiFePO4batteries. See battery specifications. Fire may occur if the correct battery charger is not used.
Ensure the battery cables are tight, secure, and have a good connection.
Follow instructions on the battery charger.
Use Smart Battery Charger rated for LiFePO4.

MAINTAINING THE BATTERY

The battery should be inspected often.
Ensure cables and terminals are kept clean and free from corrosion, dirt, or build-up of any kind. Use a dry cloth to clean.
When possible keep batteries at a moderate temperature.
Dispose of batteries properly. Must be recycled.
Store battery at 50% SOC.
Charge and discharge according to battery specifications.

INSTALLATION

Do not reverse the polarity! The battery has safety protections, but the damage may occur, and the warranty is voided.
Check battery voltage before use. Make sure the battery voltage matches that of the battery charger and load.
Properly size your battery cables for your application.
Battery cables must be crimped or preferably, soldered, and crimped. Soldered connections alone are not acceptable. High-quality, UL-listed battery cables are recommended.
The battery terminal must be clean to reduce the resistance between the DC terminal and cable connection.
Do not connect the positive terminal and negative terminal of the battery to each other with any metal object (such as wire).
Install in an environment with minimal heat. Warranty voided for terminal burnout due to excess heat and improper maintenance.
Install in any orientation.
Battery terminal torque – 7.7 – 7.7 Nm
Use proper fusing.
The terminal lugs are in a separate bag within the box.

BLUETOOTH INSTRUCTIONS

By downloading the Android™ or Apple® app on your smartphone or tablet, you can monitor the following information:

• Battery Voltage
• Battery Current (Amps)
• Battery Charge Status(SOC)
• Charge/Discharge State
• Battery Cycles
• Battery Temperature
• Remaining Capacity (RMC)
• Design Capacity (DCAP)
• Full Charge Capacity (FCC)
• Average Time: Empty/Full

CONNECTION TO THE BATTERY
Make sure you have the latest version of the AIMSBATB app that can be found on Google Play for Android and the App Store for Apple (IOS). Turn on your Bluetooth. Tap the AIMSBATB icon to open the app. It will search for all AIMS’ smart batteries within range of your Bluetooth device and a list of batteries will appear. If your batteries are not listed, move closer to the battery location and swipe your finger from top to bottom on the APP. This will refresh the screen. Once the battery list is displayed, tap the battery for more information. You can also search the battery’s serial number if your battery bank has several batteries. The serial number is located on the battery. Note: The app can only communicate with one battery at a time. You must disconnect from one battery to connect to another one (go back to the battery list screen). Also, if any device (such as cell phone or tablet) is connected to a battery, no other device can connect to that battery until the first device disconnects.
NOTE: Screens and data displayed in this manual may change as we continue to make updates to the app as needed.

BASIC INFORMATION

The second screen displays basic information such as, real-time current and voltage. The State of Charge (SOC) circular graph, like a fuel gauge, displays the percentage of the remaining charge in the battery. At the bottom of the screen, you will find the battery state and number of charge cycles.

DETAILED INFORMATION
The next screens display more detailed information. The thermometer shows the current temperature. The battery image displays RMC (Remaining Capacity). You will also find  DCAP (Design Capacity), FCC (Full Charge Capacity), Average Time to Empty (ATTE), and Average Time to Full (ATTF), serial #, and date.
