Two RJ45 sockets [6] are provided, one for connecting the CAN interface from the battery to
the system controller or directly to the inverter depending on the brand, and another for
connecting the battery to another battery or for a termination resistor (more detail later in
manual).
A DB9 Serial Connector [7 - concealed] is fitted to the upper left-hand side of the housing for
use by technicians for programming the required profile onto the BMS or updating
firmware. The required profile is typically loaded by Freedom Won prior to delivery but
installers are advised to obtain the correct adapter to allow Freedom Won or the distributor
to program batteries remotely on behalf of the installer via the installer’s Windows laptop if
necessary. Note the correct adapters as below:
For models up to and including the Lite Business 60/42 a DB9 RS232 to USB adapter
cable (Figure 2.2) is required. The DB9 plug must have the male pins and is supplied
by Freedom Won with each battery (note that only the Mecer brand supplied by
Freedom Won is guaranteed to work).
For the Lite Business 80/56 a CANdapter is required (Figure 2.3). This is available
from Freedom Won.
An error reset button [8 - concealed] is positioned adjacent to the DB9 plug.
Freedom Lite is also fitted with a State of Charge (SoC) display [9], which includes a red LED
error indicator [10] and below it a “low power” indicator.
