CHARGING SYSTEM BASICS

Aerolithium 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 forces the current down 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 over-current protection means our BMS can handle any aircraft alternator without crowbar protection as needed by other sellers.
Self discharge is around 1% a month for the 1st year, then, it can sit for years without degradation. the battery will sit naturally at about 13+ volts for a long time; a 98% discharged state would be anything less than 9.0V. Upon a LVD, simply attach charger; no disconnecting of negative lead or jump starting required.  Use a LiFEpo4 charger at 14.4V.
Aerolithium now uses Active cell balancing.

WHY AEROLITHIUM 

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.
