2.0 Introduction
Congratulations, you have purchased a state-of-the-art lithium battery proudly designed,
engineered and built in Australia.
This Operating & Maintenance Manual describes how to safely operate and maintain the High
Power (HP) range of 48V batteries for off-grid and grid connect systems.
This User Guide covers the following batteries:
• LBS-48110-HP-REG
This manual does not cover installation. Installation of this battery is to be performed by a
qualified, accredited and licensed installer.

3.0 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 has reduced
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. Extra capacity ensures lower DOD, extended
life and a higher financial return on your investment.
LBS SP batteries have a cycle life of 5,000 at 50% and 2,000 at 80% DOD.
4.0 Battery Management System
Your battery comes with a Battery Management System (BMS) mounted internally.
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 Standard Power (SP) family 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.
The LBS High Power (HP) family has a BMS with sophisticated diagnostics and if that is a
requirement of your design then contact LBS about their HP battery products.

7.0 Care and Maintenance
Like any battery, the environmental conditions impact the health and longevity. Therefore,
consider the following with respect to proper care and maintenance of your lithium battery:

1. If not intending to use the battery for a prolonged period of time (one week or longer),
turn off the voltmeter by selecting ‘Meter Off’ on the red rocker switch. This will ensure
the voltmeter is isolated and not drawing a small current. If the voltmeter was left on,
then over weeks and months it would drain the battery and ultimately flatten it.
2. If the battery is unintentionally discharged flat then it can be recovered. First remove
all loads sources and switch off the LED voltmeter. Apply a ‘dumb’ charger which
charges the battery without needing to ‘see’ the battery first.
3. For long battery life, keep it charged at above 13V at all times. Check the battery once
a month. If the open circuit voltage has dropped to 13V or below, then give it a boost.
Ensure the voltmeter is turned off at the red rocker switch.
4. All batteries, whether they are lead acid or lithium degrade faster in extreme cold and
extreme hot environments.
a. Do not charge battery when the ambient temperature is less than zero or above
45oC.
b. Do not operate the battery in environments are -20oC or above 60oC. Doing so
would reduce its life expectancy.
8.0 FAQ
Will the battery be damaged if allowed to fully discharge?
Firstly, the BMS has a low voltage disconnect at around 10.5V, so the battery will never
discharge to zero volts. If the battery is flattened and cuts out at LVD at 10.5V then it can be
recovered without damage if on occasion. If it is done repeatedly then it will have a negative
impact on longevity.
Maintaining the battery charge at 13V or higher will maintain good battery life.
Look after your lithium battery and it will give you many years of service.
Can the battery be recovered from flat?
Yes. See Section 8.
Does the battery capacity degrade over time?
Yes, all batteries degrade slowly over time, even with no load sources connected. Storage
temperature is important to degradation. Roughly every 10oC above ambient 20oC doubles
the degradation rate. Cool ambient conditions are better as it slows down degradation rate.
