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 Back-up Batteries

EFIS battery by Aerolithium is a newer simpler way to have the avionics backup power you need.

A very lightweight unit that can be configured with the Dynon Molex connector or any connector you need. Either send in your old one or we'll obtain it online. This EFIS backup battery does NOT have a BMS, and for good reason... it doesn't need one! A backup battery, like an ELT battery, is for emergency use only and never get used regularly (hopefully! ). Therefore, it never discharges so it never needs to be connected to the main bus for recharging!
By its very nature, the backup panel battery needs to be isolated from the electrical system as opposed to lead-acid types that DO self-discharge a lot and need to be constantly charged.
Adding a BMS unnecessarily complicates what should be a simple standby battery that if ever it does get used and discharged there is no worry that the BMS will cut it off before it has discharged 80% of its power. It is an expendable item in an emergency.
