Lithium LiFePO4 Battery 12V50Ah | 100Ah | 200Ah
AIMS Power’s 12 Volt LiFePO 4 battery product line has a battery for every application. The LiFePO4 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 LiFePO4 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.

VENT TUBEUnder the conditions of the battery’s chemical reaction, the internally generated gas gathers in the ventilation tube through the vent hole and the upper and lower openings, which is conducive to the internal gas dispersion of the battery, to ensure the internal pressure balance of the battery cell, and to avoid potential safety hazards of the battery cell.
SAFETY VALVEWhen the internal pressure reaches 1.2 ± 0.1Mpa, the positive electrode tab and the cap are disconnected to stop the internal chemical reaction of the battery; when the internal pressure reaches 1.8 ± 0.1Mpa, the safety valve will open, and the gas will discharge to avoid the risk of explosion.
BATTERY CELL CYCLE PERFORMANCE
As the depth of discharge decreases, the cycle life gradually increases; 1C 100% DOD charge and discharge cycle life ≥ 2500 cycles; 1C 50% DOD charge and discharge cycle life ≥ 6000 cycles.
BATTERY CELL CYCLE PERFORMANCE @ .5C & 1C
At high temperatures, the SEI film decomposes, cracks, or dissolves, resulting in continuous consumption of lithium ions and rapid decline in capacity.
At low temperatures, the active substance in the battery is low, the internal resistance and viscosity of the electrolytes are increased, the ion diffusion rate is slowed down, and Li + is more difficult to intercalate and easily disengage, which causes the capacity to decrease rapidly.

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 INFORMATIONThe 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 INFORMATIONThe 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.
