Aerolithium Starter Battery Unique Features:

  • BMS programming on select batteries gives it both an LVD and UVP exclusive protection feature so that any accidental or parasitic drains  wont reduce the battery charge completely. also known as ' auto-jump feature'

  • Batteries are waterproof and immune to vibration. Compatible with all alternators that put out 14+ volts.

  • The aluminum case is thermally conductive. Major benefit: Any internal heat is transferred to the case like a heatsink.

  • Bidirectional terminals.

  • No extra mounting bracket to buy, mounting bracket included if needed, firewall bracket fits Vans RV hole pattern.

  • LVD / Low Voltage Disconnect, at 9.6V

  • Aerolithium Batteries also have our exclusive Battery ' Auto-jump' feature - if ever the master switch is accidentally  left on, simply

  • push the 'awake' button ( remote mount cable included) and the battery comes back to life to start your engine.

  • A GPU will never be needed. You will never be stuck on an isolated airport in the middle of dark night, hungry, cold, and stressed out for lack of power. 

  • Remote panel battery cell voltage monitor LED display optional

  • Shows cells voltages and total voltage so that any undervoltage, overvoltage, or imbalance condition can be seen in real time. Over discharge protect voltage is 9.6V.. This aligns with Carbon Cub  V indicator color range.

  • Display also features an LVA - Low Voltage Audible Alarm beeper should any cell drop to 2.8 volts.

  • Internal heater option... special order ( + $100 ) ( Battery can be located in cabin without any vent tubing.)

  • 24V available custom built to your specs and Ah, email for info, see slide show

  • All Aerolithium batteries are in compliance with Rotax 912is manual section 24-00-00 pg 4 and SB 912 I - 005is

EFIS and Back-up systems Batteries

Backup / standby batteries by Aerolithium are a newer simpler way to have the avionics and electrical system backup power you need.

These very lightweight batteries can be configured with any connector  needed. Either send in your old one or we'll obtain it online. Our   backup systems batteries are made to order in varying ah sizes  and are configurable in dimensions, casing, and terminal styles.

Another option is to have a larger 30 / 45Ah backup system battery to fly several hours longer without an alternator, this saves your starter battery from being depleted if u have to land and take off again without a functional alternator, it would  eliminate the need for emergency landings due to lack of power.   30Ah systems backup - $375,  45Ah - $450.
