  3. Battery

    in Forum Information & News from the Admin

    Posted

    The way I read the maintenance manual you have the option of a led acid battery OR the LifePo4 battery (lithium). No LOA required

    11.2.6 Battery
    Lead-acid battery
    Lead-acid maintenance-free battery is installed on firewall. Battery can be charged directly
    in the airplane after its disconnecting from the onboard electrical system.
    Technical parameters:
    Voltage 12 V
    Nominal capacity 20 Ah
    Max. discharge current 300 A (5 s)
    Short circuit current 1,000 A
    Range of operation temperatures - 20 to + 60 °C (     -4 to + 140 °F )
    Service life is about 3 - 5 years or at capacity drop below 80 %

     

    Weight: 6 kg (13 lbs)
    If the airplane is not operated for more than one month, then remove the battery from the
    airplane and store it.
    Always store the battery fully charged at temperature of 20 °C ( 68 °F ). Daily discharging is
    less than 0.1 % of battery nominal capacity.
    Regularly recharge it up to the full capacity of charging once a month.
    LiFePo4 battery
    LiFePo4 maintenance-free battery is installed on firewall. Battery can be charged directly in
    the airplane after its disconnecting from the onboard electrical system.
    Technical parameters:

     

    Nominal voltage 13.2 V
    Capacity 9.2 Ah
    Pulse discharge current 480 A (10 s)
