As experts and innovation drivers in the field of mobile energy, we are constantly developing our product range. Now we are launching the AIR-LPB 12-12, offering a high level of safety paired with improved capacity. Approved according to UL2054 and with a capacity of 12Ah (156Wh) – instead of the 10Ah (128Wh) that was previously common in this size – we are putting another exclamation mark on avionics batteries. More and more technology in gliders is creating an ever-increasing demand for energy – whether it’s a radio, transponder or glider computer, nothing works without electricity.
The certification according to UL2054 (industrial batteries) enables you to register our AIR-LPB 12-12 with the LBA via a CS-Stan 0034.
Compared to commercially available lead batteries of the same size, our new LiFePO4 battery has the following Advantages:
- 1/2 weight for the same size – only 1.2 kg
- 2500 charging cycles vs. 350 to 600 charging cycles
- 100% capacity utilisation vs. 65% recommended depth of discharge for lead batteries
- Fast-charging capability (2C) Lead-acid batteries reach full capacity only after 14 hrs.
- Integrated BMS (Battery Management System) with:
- Charge balancing of the individual cells
- Protection circuit against short circuit
- Deep discharge protection
- Overvoltage protection
- Charge temperature monitoring
With the same size, LiFePO4 batteries have a higher energy density, i.e. a weight saving of 50% is achieved. The AIRBATT AIR-LPB also scores in terms of depth of discharge, number of cycles and charging time. LiFePO4 batteries allow the use of almost 100% of the capacity, offer at least 2500 charging cycles and are fast-chargeable with a max. charging current of 5A(2C).
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 short-circuit protection circuit and deep discharge protection. Because the BMS limits the current draw to 20A, the AIRBATT Energiepower 12V 12Ah 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.
For the AIRBATT Energy Power series, we offer various chargers from the AIRBATT Powercharger product range – here we have designed the Duo Charger for lead-acid and LiFePO4 batteries especially for use in the club. The use of commercially available lead-acid chargers of other brands is not recommended, as we are unable to judge whether the automatic charging system designed for lead-acid batteries will not damage the LiFePO4 batteries.
