Our Signature custom Features


Our std. 12V battery Ah sizes are 7, 9, 12, 18, 24 and up to fit all aircraft and engines. If you need a custom battery built, please contact us. Any voltage and capacity

BMS circuit


Digital programmed software operating system.
Low volume production allows faster adaptation to newer components and technologies.


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


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


  • Cells - High rate LiFePO4

  • BMS - proprietary full featured,

  • Copper bus bars for high current,

  • Voltage - 14.4 and 28.8 systems

  • Specific energy density - 128wh/kg

  • Super capacitor start assist for low temps


LiFepo4 chemistry is compatible with lead acid charging profiles.



Aerolithium experimental aircraft batteries are compatible with all aircraft charging systems as a drop in replacement for AGM batteries. Our BMS will accept the same charging voltage and current.  This acceptance of a higher current does not harm the alternator as it puts out only what it is designed to and the BMS in our battery limits the charging current to its own limit as well. As the battery's voltage increases it reduces the current  in the absorption phase. Aerolithium's BMS will protect against any overvoltage / over current during charging.
Any discharging will not be interrupted.                                                                       
Aerolithium's exclusive overcurrent protection means our BMS can handle any aircraft                                alternator without crowbar protection as needed by other batteries.
     Aerolithium now uses Active cell balancing.
