Lithium LiFePO4 Battery 12V
50Ah | 100Ah | 200Ah 

AIMS Power’s 12 Volt LiFePO 4 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 easier to maintain compared to other battery technologies. The LiFePO 4 technology has better thermal and chemical stability, which improves battery safety and 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 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 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 4battery 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 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 fire, on stoves or 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 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.
Maximum Battery Wiring Recommendation

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

CHARGING
Only use battery chargers made for LiFePO 4 batteries. 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 battery charger.
Use Smart Battery Charger rated for LiFePO 4.

MAINTAINING THE BATTERY

Battery should be inspected often.
Ensure cables and terminals are kept clean and free from corrosion, dirt or build-up of any kind. Use 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 damage may occur, and warranty 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.
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)

CONNECTION TO THE BATTERY
Make sure you have the latest version of the AIMSLFP app that can be found on Google Play for Android and the App Store for Apple. Turn on your Bluetooth. Tap the AIMSLFP 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.

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 percentage of 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 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.
