AIMS LITHIUM BATTERY 12V 100Ah LiFePO4 with Bluetooth Monitoring


12V, 100Ah, no memory problems, >4000 charge/discharge cycles up to 8x more than GEL, AGM or lead, replaces 12V AGM, Gel & Lead batteries. Not intended to use as starting batteries. Ideal for back up power in RVs, boats, recreation vehicles and off grid back up power systems. Uses the same space as a your existing 12V battery but much  lighter. Made for extreme temperatures. Maintenance free. Must use lithium battery charger (LiFePO4).

AIMS Lithium Battery 12V 100Ah LiFePO4

For power, efficiency and longevity, this AIMS lithium battery offers everything a backup power system needs. AIMS Power has introduced its new battery product line of LiFePO4 batteries to keep both residential and commercial users out of the battery graveyard. Known as lithium batteries for short, a LiFePO4 (lithium iron phosphate) deep cycle battery is designed to maintain constant output voltage, providing more efficient power. This allows the cell to deliver virtually full power until it is discharged without harming the battery, and it can greatly simplify or even eliminate the need for voltage regulation circuitry.

A 12V lithium battery 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. With 100 ampere capacity, this AIMS battery is ideal for personal or light commercial use. (Please note that this battery is not intended to replace starting batteries.)

Benefits of a Lithium Deep Cycle Battery

The AIMS Lithium Battery 12V 100Ah LiFePO4 battery is designed for safe, stable power. This battery has a much longer cycle life capacity and is easier to maintain compared to other battery technologies. It is rated for more than 4,000 charge-discharge cycles and is built with a sophisticated Battery Management System including multiple safety protections. The LiFePO4 technology has better thermal and chemical stability, which improves battery safety and is packed with power in a small and lightweight footprint.

An AIMS battery offers features you won’t find in the no-name battery market. While other companies use B-grade cells for cost reasons, AIMS only uses A-grade cells. They have double the average lifecycle, which means one AIMS LiFePO4 battery can last as long as two no-name batteries. Bluetooth monitoring software is available so you can monitor the voltage level from a smartphone and know if a charge is needed.

These batteries are backed by a battery cell IEC rating that specifies requirements and tests for the safe operation of secondary lithium cells and batteries used in industrial applications – including stationary applications – plus a prorated 10-year warranty.
