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:
- BTLP12V110-100SL
- BTLP12V150-200SL
- BTBLUESLIM110-DC40
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. BAINTECH offer these general guidelines; however, you should seek BAINTECH advice or that of a qualified electrical tradesperson if you are in doubt.
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
- Do not allow water to enter
- Do not charge battery below 0oC
- 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:
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 BAINTECH advice and consider making use of BAINTECH mounting
brackets to safely secure the battery.
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 into the enclosure. Use only existing mounting holes in the
battery and short screw lengths no greater than 13mm.
We strongly recommend the BAINTECH 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.
Maintain an acceptable temperature range
Like all batteries, BAINTECH batteries operate and perform the best, as well
as last the longest, in a cool and stable temperature environment of between
10oC and 25oC. The maximum window of acceptable operation is 0-45oC.
If you regularly operate 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.
Operating outside of these guidelines diminishes the life and performance of the battery and voids the warranty.
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.
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. If it is likely
that a water will be on the floor where the battery is located, ensure the
battery is facing upwards with the terminals (and electronics) on the top, so
that any water that gets into the bottom can drain out again without touching
the electronics.
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.
Do not short circuit the battery
Whilst the BMS will protect the internal cells from short circuit, it is
highly recommended to avoid short circuiting 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 keep the plastic caps screwed on when not using the terminals.
Always perform work on passive wiring first and connect the live battery as the last connection. If you have to 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 BAINTECH or a suitably qualified electrical tradesperson.
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.
-
BAINTECH batteries have a cycle life of 5,000 at 50% and 3,000 at 80% DOD.
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 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.
Installation
Storage
The Slimline battery is likely to be stowed in a car, RV or 4WD or 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 illustrates some handy stowage solutions. The primary benefit of the
slim battery is that it can tuck away behind or under 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.
As with all battery installations, ensure it is securely strapped down or secured in place before heading out on the road.
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 protected and operating safely at all times. 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 6 for illustrative purposes.
Discharge Curve: Lithium vs Lead Acid
The Slimline battery voltages below are a useful guide:
- A normal full battery open circuit voltage (Voc) with no load rests at 13.3V to 13.6V;
- Depending on the load voltage may dip 0.5V below the Voc;
- Below 13V Voc the battery is low, and should be charged to promote a long lifespan.
- Below 12V Voc the battery is close to empty, and should be charged straight away; Low Voltage Disconnect (LVD) is set at ~10.5
