Quality of Materials

Quality cells = quality battery

You have a choice in Lithium Batteries: Choose Wisely!

  • Cells - Cylindrical A123 LiFePO4

  • BMS - Advanced, digital, premium features

  • Terminals - Copper core for high current, less resistance than brass

  • Enclosure - Anodized aluminum, carbon fiber, bamboo

  • Discharge graph - showing flat power curve. This is why Lithium is better than lead-acid.

  • Operating temps - minus 20 to 65 Celsius

  • Electronics - Advanced BMS with cutting-edge circuitry designed specifically for aviation use.

  • Voltage - 14.4 and 28.8 systems

  • Specific energy density - 118wh/kg


Our Signature Features

choice in lithium batteries


Our starter battery Ah sizes are 7.5, 10, 15, and 23 to fit all aircraft and engines.

BMS circuit


Digital programmed software operating system (vs analog type with fault indicator).
Low volume production allows faster adaptation to newer components and technologies.

10Ah and15Ah lithium battery


To accommodate all the various Ah capacities, shapes, dimensions, and weights clients ask for, we offer a multitude of choices of different cases.

compatible withaircraft electrical systems


Superfast charging = less work for the alternator, BMS regulated and protected for any size alternator/ generator

Bamboo and carbon fiber


Bamboo, carbon fiber, and aluminum, no limitations on use or environment.

 An engines electrical system  is said to be a 12 volt system, but this is slightly misleading. The charging system in most aircraft will generally produce a voltage between 13.5 and 14.4 volts while the engine is running. It has to generate more voltage than the battery's rated voltage to overcome the internal resistance of the battery.
This may seem strange, but the current needed to recharge the battery would not flow at all if the charging system's output voltage was the same as the battery voltage. A greater difference of potential (voltage) between the battery's voltage and the alternator's output voltage will provide a faster charging rate.  
Thus a Lithium battery will  charge quicker than the typical sealed (or AGM type) lead acid  battery.

As you already know the primitive lead-acid battery is going the way of the horse and buggy.

Energy storage in a lithium battery has advanced to the point of being very safe; very lightweight, 1/4th or less the weight of a lead battery, a longer life span; thus cheaper than SLA over time.  

No battery tender required, higher resting voltage, higher cranking voltage/amps, cleaner, no gassing / no corrosion, less toxic, and environmentally much greener than lead-acid.
Whether you have a Lycoming or Continental or Rotax or other engines consider that a lithium replacement battery will last 5 times longer, and although costing about 2 x's more than a stock lead battery, it pays off in the long run, while providing the benefits of lighter weight and smaller size. For those infrequent flyers, a charged Aerolithium battery can sit for months and still fire up your engine.

Lithium lightweight airplane starting batteries are for those that want faster acceleration, increased useful load, shorter takeoffs and landings, have weight and balance issues, want less mass/ stress during hard G turns, no maintenance, install anywhere, and like being on the leading edge of technology.  

The Lithium Iron Phosphate chemistry of these batteries is non-hazardous, non-flammable, and non-corrosive. Extremely small self-discharge, no memory like NiCd, and can be serviced/refurbished if ever. These Lithium aircraft starting batteries are a retrofit unit that will work in ANY fixed-wing aircraft, helicopters, light sport planes, experimental aircraft, LSA, and gyrocopters.

Engines with fuel injection or electronic ignition are highly advised to have a backup battery installed.
