AIRBATT Energiepower AIR-LPB 12-18 AVIONIK 12V 18Ah LiFePO4 avionic battery

The AIRBATT Energiepower AIR-LPB batteries ( LiFePO4 ) consist of high-quality, certified cells and offer several advantages over standard lead batteries of the same size:

• 1/2 weight for the same size - only 2 Kg.
• 2500 charging cycles vs. 350 to 600 charging cycles
• 100% capacity utilisation vs. 65% recommended depth of discharge
• Quick charge capability (2C)
• integrated BMS (battery management system) with:
  • charging balancing of the individual cells
  • Protection circuit against short circuit
  • Deep discharge protection

With the same size, the LiFePO4 batteries have a higher energy density, i.e. a weight saving of 50% is achieved. AIRBATT LiFePO4 batteries also score in terms of depth of discharge, number of cycles and charging time. LiFePO4 batteries allow almost 100% of the capacity to be used. In contrast, lead-acid batteries should not exceed a recommended depth of discharge of more than 65% to avoid entering the range of deep discharge, which is harmful to the batteries. In addition, LiFePO4 batteries score with their high number of cycles of at least 2000 charging cycles - a multiple compared to the conventionally used lead batteries, which range from 350 to 600 charging cycles depending on the manufacturer and product series. With a recommended max. charging current of 5A (2C), the AIRBATT AIR-LPB 12V 18Ah is also fast-chargeable.

AIRBATT Energiepower LiFePO4 batteries are tested batteries. During quality control, each individual battery is subjected to the following tests:

• Capacity test 
• High frequency test 
• acceleration test 
• high current test

The BMS integrated in the battery housing is equipped with an active balancer for charge balancing of the individual cells, a protective circuit against short circuits, as well as a deep discharge protection. Because the BMS limits the current draw to 30A, the AIRBATT AIR-LPB 12-18 is not suitable as a starter battery. With our AIRBATT Startpower product series, we offer you LiFePO4 starter batteries with high starting current and low weight.

We offer chargers for the AIRBATT Energiepower series with the lead-acid and LiFePO4 chargers of the AIRBATT Powercharger product line. Commercially available lead-acid chargers with a charging voltage between 14.5V and max. 14.8V with an IU charging curve (CCCV) can also be used. It is imperative to ensure that the LiFePO4 batteries are not exposed to a charging voltage of more than 15V, otherwise they may be damaged. Chargers with Refresh or Recond mode and a charging voltage of 15.5V (or more) are therefore completely unsuitable. With these devices, there is no guarantee that this automatic charging system, which is designed for lead batteries, will not also start with LiFePO4 batteries.

*The battery consists of individual cells in their own housings and electronics and is therefore a battery device.

*The plastic housing is only an enclosure and is not waterproof. Submersion of this battery is not possible.

*The series connection (24V circuit) is only possible under certain conditions and after consultation with an ACCU-24 employee!

*The battery is a supply battery and not a starter battery.

*Export to the United States of America is not permitted without written consent from ACCU-24.

*It is imperative to observe the specifications of the aircraft manufacturer and the operating Manual!
