Freedom LiTE Installation Manual Revision 14
P a g e 1 | 30
1. Introduction
This manual is intended to aid an installer with the installation and commissioning of the
range of Freedom LiTE lithium iron phosphate (LiFePO4) energy storage models. This
document is not intended to provide detailed information of the inner workings of Freedom
LiTE that is not relevant to a person that is performing the installation and final
commissioning. Supplementary information relating to programming of the built-in battery
management system and advanced troubleshooting is available to approved integrators
directly from Freedom Won.
This manual does not attempt to cover all the details pertaining to the setup of third-party
equipment in relation to the interface and necessary functionality to work with the LiTE.
Freedom Won however is available at the contact details on page one to provide direct
support where necessary for supported inverter brands.
2. Product Description
The Freedom LiTE technology is available in various standard sizes to meet all residential,
commercial, and industrial applications, ranging in models from 5kWh up to 800kWh. Larger
systems are designed by installing multiple units of the same model battery in parallel.
Freedom Won offers the following ranges in the LiFePO4 technology:
1. LiTE 12V
2. eTower
3. LiTE Home and Business
4. LiTE HV Home and Business
5. LiTE Marine
6. LiTE Mobility (golf carts, forklifts etc)
7. LiTE Commercial (including LiTE Commercial HV and HV+)
8. LiTE Industrial
This manual covers the standard voltage models of the LiTE Home and Business range from
5kWh up to 80kWh. Please refer to the manuals specific to the other ranges.
The standard LiTE voltage is 52V nominal (to suit 48V systems). The Freedom LiTE HV ranges
are designed for specific Higher Voltage inverters. The LiTE Commercial range has models in
52V and various higher voltages up to 800V (including the HV and HV+ models). The
Industrial range is available in HV+ only (600 to 800V).
The LiTE Marine range of lithium batteries offers similar specifications to the Home range
including 13V, 26V, and 52V options to suit 12V, 24V and 48V inverter systems respectively.
These models are water resistant (IP65) and designed for mounting on the floor or
horizontal deck and have dimensions that are different to the LiTE Home models.
For more information on all these models refer to the Freedom Won website.

Table 2.1 provides an overview of the 52V Freedom LiTE Home and Business range. There
are eight Freedom LiTE models in the Home and Business range, as included in the table,
classified in terms of energy capacity.
An image with numbered labels pertaining to the following paragraphs is provided in Figure
2.1. The model number denotes with the first number [1] the total energy storage capacity
in kWh of each model. The second number [2] denotes the maximum amount of energy in
kWh that should be withdrawn per daily cycle (on average) in order to optimise the life of
the lithium cells. This equates to 80% of the total for each model i.e. 80% depth of discharge
(DoD). Note that all Freedom LiTE batteries offer a maximum of 90% DoD as standard.
The range is very compact with the “Home” models up to the LiTE Home 20/16 intended to
be wall or floor mounted –all models are supplied standard with “keyholes” on the back for
wall mounting or plastic feet for floor mounting. The larger “Business” range is designed for
floor standing only, with either plastic feet or aluminium feet with plastic pads on the
underside.
The Ah capacity is also provided in the tables for each model for easy reference.
The maximum current for each model is governed by the rating of the built-in circuit breaker
[3], which has been sized below the maximum current capability of the lithium cells. There is
no significant cell temperature rise during operation and no active cooling of the cells is
required for this range of models. The time limit for operation at the maximum current is 30
seconds in a 60 second cycle. To ensure that the circuit breaker does not trip in normal
operation it is advised that the design of the system aims to remain at or below the
continuous current value.
For the 52V models the absolute maximum allowable voltage when fully charged is 56V,
however a more typical inverter charge setting is 55.8V. The voltage normally used as the
minimum cut off is 48V, however this will not typically be reached when operating down to
90% Depth of Discharge (DoD). The BMS will command the connected inverter with CAN Bus
interface to stop discharging the battery at 10% SoC (90% DoD), which roughly equates to
49,0V). Under high load the voltage may drop to 48V whilst still above 10% SoC. A voltage of
48V or even lower can be observed in systems without a CAN Bus interface or where the
standby current draw on the inverter has caused the battery to be discharged below 10%
SoC. The battery breaker will eventually trip the battery at around 47V to protect the cells
from undervoltage.

production from 9 September 2019 this port is no longer provided owing to migration
of all interfacing to CAN Bus)
6. CAN Bus Sockets x 2 (RJ45) (one socket must contain a termination resistor if end of
line)
7. USB Programming Port (not visible in photo). Note that in models manufactured prior
to May 2020 this port is a DB9 plug.

The weight of each model is given in Table 2.1. The Freedom LiTE Home 5/4, 10/8 models
can be manually handled by two people. The 15/12 and 20/16 can be manually handled by
four people. The larger units may require lifting equipment of varying degrees for handling
and installation as explained later in this document.
