MODES OF OPERATION
The LBAT12150-SB Lithium Battery has two modes: Operational and Non-Operational.
OPERATIONAL MODE
The LBAT12150-SB Lithium Battery has 3 states in Operational Mode:
Normal State: The metrics that the Lithium Battery monitors (voltage, current and temperature) are within the
operational level of the cells and other components in the Lithium Battery.
Warning State: The metrics that the Lithium Battery monitors are threatened to go beyond the operational level of
cells or other internal components. The Battery’s protective disconnect device will allow charging and discharging.
Alarm State: The metrics that the Lithium Battery monitors are beyond the operational level of cells or other internal
components. The Battery’s protective disconnect device will disconnect the cells from the terminals and the Lithium
Battery. This means that either charging, discharging or both are disabled.
OPERATION STATES DEPENDENCIES
TABLE 1
State Protective Disconnect Device Communication BMS
Normal State Conducting Yes Active
Warning State Conducting Yes Active
Alarm State One current direction conducting or non-conducting Yes Active
CHARGING DISABLED CAUSES
Charging is disabled under any of the following conditions:
Over-current during charging, the charge current is too high.
Over-voltage due to charging, the charger voltage is too high or the Battery cells are out of balance.
The temperature is outside the allowable range for charging.
The protective disconnect device is too hot.
DISCHARGING DISABLED CAUSES
Discharging is disabled under any of the following conditions:
Over-current during discharging, the load current is too high.
Under-voltage due to discharging, the Lithium Battery is at or the load current is too high for the Battery's SoC.
The SoC ‘off’ level has been reached.
The temperature is outside the allowable range for discharging.
The protective disconnect device is too hot.
NON-OPERATIONAL MODE
When in Non-Operational Mode, the LBAT12150-SB Lithium Battery will not function/operate and cannot be used.
This can happen if the BMS detects a malfunction in the Battery’s monitoring and control, or when a deep-discharge
has caused cell damage. A deep-discharge occurs when one of the cells is at 1.5V or lower. This is even possible
when the Lithium Battery is at 10 V. The Lithium Battery will store the state internally and becomes unusable. The
Battery’s protective disconnect device is non-conducting.

INSTALLATION

may be placed on its long or short side, do not mount upside down. Use appropriate fastening brackets and
xtures for mounting.
A mounting bracket is available for purchase to
securely mount the Lithium Battery.
CONNECTION WIRES
CAUTION:
Batteries are capable of supplying very large currents. Fuses must be placed as close as possible to the
battery's positive (+) terminal to protect the cable from damaging currents — Failure to do so could cause re
or personal injury.
When using more Lithium Batteries in parallel the wiring should be sized and specied according to the
maximum current the parallel bank can deliver. See page 22 for more information.
Use suitably rated cables, fuses and cable lugs which meet the requirements for your installation. Refer to your
devices (charger or load) installation requirements for further information. Always use the correct crimp tools to crimp
the cable lugs and follow the instructions provided by the cable lug manufacturer.

COMMUNICATION AND FASTON CONNECTIONS
PROTECTIVE COVER REMOVAL
All FASTON connections can be made in one central place under the
Protective Cover. The cover can be easily removed with light force and
then re-tted on when nished installing.
CONNECTING THE COMMUNICATION AND FASTON CONNECTIONS
CAUTION: Never use the cabling to lift the Lithium Battery, even when the cable clamps are holding it in place.
The FASTON connection inputs are marked on the inside of the protective cover. The connections can be made
using standard 4.75mm (0.2") wide automotive FASTON crimp terminals.
Once all FASTON cable connections are made, use the supplied cable clamps and Phillips head screws to secure
cables into the integrated cable strain relief. Do not feed the CAN Bus cable through the integrated strain relief as
this may damage the cable.

CONNECTING TO THE CAN BUS INTERFACE (FOR FUTURE USE)
IMPORTANT: The CANBus Interface is not compatible with REDARC R-Bus devices.
CONNECTING THE DATA CABLES
The wired communication interface must be used in a bus network topology (see Table 2). Do not use a ring–or a
star topology. The wired communication interface specications restrict the Bus length /Bus speed.
TABLE 2
Bus Lengths (L) Maximum Stub Length (S) Accumulated Stub Length
250 m (820') 11 m (36') 55 m (180.5')
CAN BUS CABLES
CAUTION: The supplied Protective Cap must be tted whenever the CANBus Interface is not in use. Without it,
water/moisture may enter the socket which may cause serious damage.
The connection to the CAN Bus can be made using standard CAN Bus cable wiring and accessories. A Y-split
CAN Bus cable and inline CANBus terminator cable is recommended for an easy installation and connection to other
Lithium Batteries.
CAN Bus
Cable
TERMINATING RESISTORS
Use terminating resistors or the inline CANBus terminator cable at the end nodes to maximise signal integrity. The
value of this resistor should be nominally 120Ω.

19
CONNECTING TO THE LIN BUS INTERFACE (FOR FUTURE USE)
The Lithium Battery includes a LIN Bus interface (Local Interconnect Network) which is accessible on FASTON 2 (LIN)
under the Protective Cover (see page 9). The LINBus interface can be used to connect to a LIN Bus master which
are often present in (recreational) vehicles or caravans.
The LIN Bus interface provides the LIN Bus master with information about the Lithium Battery like SoC and other
data. Depending on the electrical installation, the LIN Bus ground can be either the negative (−) terminal or the
FASTON GND. Make sure no ground loops are made when using the FASTON GND.

LIN
CI-BUS PROTOCOL
To support easy integration within the RV/ caravanning industry the LIN Bus protocol is congurable. One of the
protocols which can be selected is the CI-BUS protocol. When enabled, the LIN Bus provides all information
necessary for the system using the CI-BUS protocol.
OTHER PROTOCOLS
The LIN Bus in the Lithium Battery can also support protocols dened by other manufacturers, this support is
extended on a regular basis and prone to change. Please email REDARC to gather information about the supported
protocols on the LINBus.
Please contact REDARC at [e-mail]

IO FASTON CONNECTION AND FUNCTIONALITY
The Lithium Battery has three electrical input or output interfaces accessible by FASTON 3 (IO1), FASTON 4 (IO4)
and FASTON 7 (IO3). These interfaces can be used for different purposes, and are congurable using the REDARC
Lithium App.
TABLE 3
FASTON IO Functionality
SoC Status
Active OFF Hysteresis
IO1 Output Generator Control Below 20% 100% 80%
IO2 Output Inverter Control Above 21% Below 10% 11%
IO3 (for future use) Reserved Reserved for future use
The list of supported functionalities will grow in the future and will be available by updating the REDARC Lithium App.
The I/O port can service as an input and output feature:
Input: When used, the input can measure a digital level between 0V and 12 V (typical value). When there is 12 V on
the input means that the input is made active, 0 V means input not active.
Output: When congured as such, the output acts as an “open drain” output. Open drain means that the output is
pulled to 0 V when active and is oating when not active.
All I/O ports are fused with an internal re-settable fuse. When overloaded, the output will stop delivering current while
the overload or short-circuit condition exists. The fuse will automatically reset when the overload or short-circuit
condition is no longer active and the output will work as normal.
