CHARGING A LITHIUM SYSTEM

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 sellers.
