1 Introduction
Congratulations! You have purchased a state-of-the-art lithium battery and we hope you enjoy many
years of trouble-free life. This Installation and User Guide describes how to connect and safely operate
the Slimline range of 12V batteries.
This User Guide covers the following SL 12V battery range:
•LBS-1275-SL
•LBS-1275-SL-DCS
•LBS-12110-SL
•LBS-12110-SL-DCS
•LBS-12150-SL
•LBS-12150-SL200
As with all batteries, you should consider the mechanical and environmental conditions that you
intend to operate the battery in to maximise overall performance and achieve the longest battery life.
LBS offer these general guidelines; however, you should seek our further advice or that of a qualified
electrical tradesperson if you are in doubt.

2 Do’s and Don’ts
This battery contains lithium iron phosphate (LFP) cells. While LFP cells are the safest Li-Ion chemistry,
the stored chemical energy represents a risk of fire, burns or explosion if misused.
Avoid injury to yourself and others, adhere to the warnings in this Guide.
•Avoid mechanical shock
•Do not expose to fire
•Do not pierce battery
•Do not disassemble
•Do not drill into enclosure
•Do not short the terminals
•Keep away from water
•Avoid direct sunlight
•Do not charge battery below 0oC or above 45°C
•Do not store battery below -20oC or above 60oC
To ensure a long and safe life from your battery, please ensure you consider the following:
2.1 Ensure the battery is physically secure
Even though lithium batteries are light weight in comparison to lead acid, they can still become a
dangerous projectile in a moving vehicle, RV, cart or boat if not secured. Ensure the battery is safely
secured before travel. If in doubt seek LBS advice and consider making use of LBS mounting brackets
to safely secure the battery.
2.2 Do not penetrate the battery enclosure
You may be tempted to drill into the aluminium enclosure to secure mounting brackets. Doing so may
inadvertently penetrate one of the cells which could cause thermal runaway and vapour emissions.
Do not under any circumstances drill or penetrate the enclosure. Use only existing mounting holes in
the battery and short screw lengths no greater than 13mm.
We strongly recommend the LBS mounting kit with screws and brackets that are designed to safely
attach to the battery. Alternatively, use strapping and clamping to secure the battery in place.
2.3 Maintain an acceptable temperature range
Like all batteries, LBS batteries operate and perform the best, as well as last the longest, in a cool and
stable temperature environment between 10oC and 25oC. The maximum window of full operation is
0-45oC. Do not attempt to charge the battery below 0°C or above 45°C.
If you regularly discharge outside of this suggested range, you should consider changing the battery
location, or actively cool or heat the environment in order to preserve battery life. If the ambient
temperature that the battery operates in is greater than 60oC, you should cease use immediately.

Avoid direct sunlight –the internal temperature of the enclosure can rise quickly due radiation from
the sun.
Operating outside of these guidelines diminishes the life and performance of the battery and voids
the warranty.
2.4 Avoid repeated shock and vibration
Whilst the battery is robustly constructed and protected in an aluminium enclosure, it is not designed
to operate continuously in high shock or high vibration environments. Normal use in a 4WD
environment is acceptable and the battery has been designed in accordance with these expected
conditions. However, dropping the battery or exposing the battery to a high number of excessive
vibrations may lead to a fault or failure of the battery.
2.5 Avoid exposure to water or salt spray
Whilst the battery is mechanically protected, the enclosure is only IP20 equivalent and is not designed
for a wet environment. Do not submerge the battery in water or expose the battery to direct water
spray.
Avoid exposing the battery long term to salty water spray such as in a marine environment to avoid
corrosion. Salt laden air may also cause corrosion in the long term; therefore, minimise exposure by
installing the battery in a protected hatch or compartment.
2.6 Do not short circuit the battery
Do not short circuit the battery. Pay attention when using metallic tools in the vicinity of the terminals,
as accidentally contacting the positive and negative terminal with a metallic object like a spanner will
cause a short circuit and spark.
Always perform work on passive wiring first and connect the live battery as the last connection. If you
must work on live circuits, exercise due care, and use insulated tools where possible. If you are unsure
how to install the battery, seek advice from LBS or a suitably qualified electrical tradesperson.
Check to ensure the connecting Anderson plugs are correctly wired (positive and negative) and do not
attempt to mismatch Anderson colours when connecting.

3 Longevity & Depth of Discharge
One of the advantages of lithium batteries over lead-acid batteries is longevity. If you want to realise
the long life potential out of your lithium battery, then consideration must be given to depth of
discharge.
A battery lifespan is rated by the number of cycles before the original capacity hasreduced by a certain
amount.
A cycle is defined as discharging from fully charged, to a percentage Depth of Discharge (DoD), and
then charging back to full again. So, DoD describes what percentage of the battery capacity is being
used each time.
NOTE - DoD is different to State of Charge (SoC, also known as Charge Level); in fact, they add together
to 100%. So, 80% DoD equates to 20% SoC.
The less DoD you use each cycle, the longer the battery will last.
This fact should be considered when choosing the battery Amp hour capacity. You will have a higher
return on battery investment if there is enough capacity at hand such that you are not heavily
discharging the battery on every cycle. A capacity ‘overhead’ ensures lower DoD, extended life and
therefore a higher financial return on your investment.
LBS Lithium Iron Phosphate (LFP) batteries have a cycle life of 5,000 cycles at 50% DoD and 2,000
cycles at 80% DoD.

4 Battery Management System
Your battery comes with an integrated Battery Management System (BMS).
The BMS is an electronic solid-state circuit board which manages the cells and protects the battery
across a range of scenarios which primarily includes over charge and over discharge protection. Unlike
lead acid batteries, over charging or over discharging a lithium battery may lead to a hazardous
scenario. Therefore, the BMS is the heart and soul of a lithium battery.
The Slimline battery BMS is a highly reliable solid-state device which is primarily designed to keep the
cells safe and the overall pack from being damaged by excessive voltage or excessive discharge event.
It has the following features:
•Cell over-voltage protection
•Cell under-voltage protection
•Over current protection
•In-rush current protection
•Short circuit protection
•Transient voltage protection and fusing, with fail-safe monitoring of the fuse
•Fail-safe operation if connection to any cell is lost
•Blocking charge above 45°C (with automatic recovery)
•Blocking discharge (all loads disconnect) above 60°C (with automatic recovery)
•Smart passive cell balancing

5.1 Stowage
The Slimline battery is likely to be stowed in a car, RV or 4WD or used as a portable battery for
camping. An important part of the battery installation is securely fixing it down or safely stowing it
away during transport so that it does not become a projectile in an accident.
Figure 2, Figure 3 & Figure 4 illustrate some handy stowage solutions (Battery Colour: Hammertone
Blue). The primary benefit of the Slimline battery is that it can tuck away behind a seat in a vehicle.
Too often space is at a premium and the slim shape and design of the battery means it can be hidden
away easily.

5.4 Connecting to the integrated DC-DC charger (DCS models only)
5.4.1 Configuring the DC-DC Charger
As you look at the 20A DC-DC charger, there is an LED and 2 rotary switches on the side face of the
battery.
1. Green LED which will illuminate when the DC-DC charger is ready to charge.
2. Rotary Switch 1 nearest the LED is called Voltage Switch.
3. Rotary Switch 2 furthest from the LED is called the Time Delay / Ignition Trigger Switch.
Figure 12: DC-DC Charger switches
The DC-DC charger is factory set at setting 0-6 for smart alternators using an ignition trigger. If you
want to use your DC-DC charger in a different mode, then you need to turn the two rotary switches
to the correct position.
After connecting the DC source via the blue Anderson plug, the vehicle engine can be started. The
green LED status light should illuminate if the battery is charging. The rotary switches will require
adjusting depending on the alternator type.
Do not attempt to plug in a DC source higher than 16V. Doing so may lead to permanent damage to
your battery.

Example: If you select ‘0’ for the Voltage Switch Position, then the source battery will stop delivering
charge once it drops to 10.0V. So that the source battery voltage does not get too low, its best to select
a higher voltage shut off point, such as ‘4’ –12.5V. For Smart Alternator installations, its recommended
to use the Ignition Trigger; Select ‘0’ on the Voltage Switch Position and ‘6’ on the Delay Switch
Position.
If installation is without an Ignition Trigger, then it’s recommended to select ‘4’ on the Voltage Switch
Position and ‘0’ on the Delay Switch Position –this configuration is best suited to traditional alternators
(non-smart).
5.4.2 Ignition Trigger Input
The Ignition Trigger Input, a red/blue plug on the front face of the battery (Figure 13), can be used to
only charge the Slimline when an ignition feed is live. This will ensure that the starter battery doesn’t
drain unnecessarily when the vehicle is not in use. Please consult your auto electrician to discuss a
suitable place to connect an ignition trigger input to in your vehicle. The Ignition Trigger requires only
a single 12V positive signal and uses the common ground of the battery. The rotary switches will need
to be configured to ignition trigger mode. Please see section 5.4.1 above.
Figure 13: Ignition Trigger Input
If you are unsure of the correct setting for your vehicle alternator, then you should contact an auto
electrician for guidance.

6 User Guide
Once the battery is securely installed and electrically connected it
will automatically be available for use. The internal BMS will
actively ensure the battery is always protected and operating
safely. The battery requires no user interface or intervention
under normal conditions.
The Slimline lithium battery voltage can be monitored by installing
an external display, such as our remote voltage monitor shown
right.
Note that unlike lead acid batteries, lithium batteries hold their
voltage over the cycle, dropping off only when the battery is ~90% discharged, as indicated in Figure
14 for illustrative purposes.
Figure 14: Voltage Curve Lead Acid vs Lithium
The Slimline battery voltages below are a useful guide:
1. A normal full battery open circuit voltage (VOC) with no load rests at 13.3V to 13.8V;
2. Depending on the load, voltage may dip 0.5V below the VOC;
3. Below 13V VOC the battery is low and should be charged to promote a long lifespan.
4. Below 12V VOC the battery is close to empty, and should be charged straight away;
5. Low Voltage Disconnect (LVD) is set at ~10.5V.
Do not attempt to charge the battery with a voltage higher than 14.6V. Doing so may lead to
permanent damage of your battery.
