If the master LiTE trips one of the slaves will take over as the master automatically without
any interruption of service.
Freedom Won offers a fair trade in on Freedom LiTE
’s on the purchase of new units, which is
an option for somebody wishing to expand their battery capacity instead of installing
parallel units. Please request more detail from Freedom Won if this is your upgrade
preference.
New units can be placed in parallel with old units up to about 4 years or 1 200 cycles, after
which it is preferable to trade in for a new larger unit.

Programming the Freedom LiTE
The serial USB plug on the side of the Freedom LiTE is used for setting up the profile of the
BMS. The USB cable required for connecting Freedom LiTE to a computer is supplied with
the LiTE. The computer must have the correct utility software installed. Programming of the
BMS is intended only as a function to be performed by Freedom Won and approved
distributors and installers. Write access to the BMS profile is password protected, however
users and owners may request read only access.

Switching on the LiTE
The LiTE
is fitted with an “ON” button. Press this button
for at least 5 seconds to switch on
the BMS inside the battery. Once the BMS has been energised you will observe the SoC
display come to life with the SoC level shown. Confirm at this stage that the error LiTE is not
illuminated (or error flash on the multicoloured ON button models). If it is, contact Freedom
Won. If the Reduced Power light is illuminated, do not be concerned, it should extinguish
after the battery has been in operation for a few hours or once it has charged up a little.
Once the BMS has been energised, the main breaker may be switched on by pushing the
breaker upwards. Ensure beforehand that you have secured the DC cables to their proper
locations and that the rest of the system is ready to receive battery voltage.
Note: On some inverters there is a large inrush current when switching on the DC supply.
It is important in these instances to pre charge the DC bus. With Victron this can be
achieved by switching on the
PV to the MPPT’s to allow them to apply voltage to the DC
bus before closing the battery breaker. If this option is not available, you can switch on
the AC input power to the Victron inverter as this allows the inverter to place voltage on
the DC bus. If you are using inverters that cannot do this, you will need to use a pre charge
resistor to pre-charge the DC bus before witching on the DC breaker.
To switch off the DC output from the LiTE, pull down the breaker. To switch off the power to
the BMS, press the “OFF” button situated to the right of the “ON” button. This will also trip
the breaker if it is still on at the time. The LiTE must be switched off fully when not in use to
prevent self-discharge.
