52,0V for approximately 60% DoD
51,0V for approximately 70% DoD
In non-CAN Bus systems fitted with DC solar charge controllers (SCC) the AC charger should
stop charging at 53.5V to allow the remainder of the charge to be performed by the SCC.
The SCC voltage set point would be set to 55,8V if BMS control is functional and 55,5V
without BMS control. Note that it may be necessary to use a slightly lower voltage initially if
the cells have not had sufficient balancing time – if the battery trips prior to reaching 55,5V
it is because one cell has reached its maximum too early. Try starting with 54,5V and then
after several days of balancing increasing it to 55,5V. For Victron systems the Lite controls
this voltage maximum automatically.
Note: For applications where voltages are measured during high current discharge it might
be necessary to adjust slightly the values given above to cater for cell internal resistance.
Note: For systems with an interface between the battery and the rest of the system it is
advisable to use SoC for controlling charge and discharge algorithms as this is the only
accurate method – using voltage as described above is only an approximation.

Accessories
Freedom Won offers the following accessories:
Table 7.1 List of Accessories
Item
Description
120 Ohm Termination Resistor – RJ45
For plugging into the second CAN port for an
end of line Battery (usually these are supplied
with CAN Enabled inverters and hence it is
generally not necessary to purchase from
Freedom Won.
RS232 to USD Adapter
This is needed for programming the Lite models
from the Lite 5/4 to the 60/42 via the DB9 plug.
CANdapter
This is required for programming the Lite 80/56
model and larger via the DB9 plug.
Eye Bolt M12
Required for lifting 15/7 and 20/14 models
using the hard point on top of the battery – for
installation onto the wall
Gantry – see price list for options
Used for lifting Lite’s onto wall mount bolts as
well as lifting the floor standing models into the
upright position. Available with various width
gantries (narrower to suit contracted
installations). Fitted with 3 500kg electric
winch, includes lithium battery and built in
charger. Can be disassembled and reassembled
in minutes for easy transportation.
CAN Bus Cables
For various inverters requiring non standard
cables.
