SETUP AND STORAGE
INSTALLATION Ensure that the area in which you will be performing installation of the battery is dry. Secure the battery firmly to the mounting surface, ensuring that no movement is possible even under significant force. You may install the battery in any orientation, including upside-down. Ensure that your proposed installation location will not cause the battery to be exposed to temperatures in excess of the maximums stipulated in the specifications table of this manual. If you believe heat may be an issue, you may consider making use of mechanical ventilation such as fans. Ensure you do not mount the battery in a way that could cause the terminals to come into contact with any metal surface or object. This is to avoid the possibility of short-circuiting the terminals. If you are intending to remove the battery from its installed location periodically, ensure there is a clear pathway free of metal surfaces and objects. Do not install the battery in a wet area such as boat decks, open ute trays or chassis mounts. Do not install the battery in a compartment dedicated to gas storage.
8
SETUP AND STORAGE
CONNECTION – GENERAL We recommend that no more than four cable lugs be connected directly to a battery terminal. If you do have more than 4 lugs, you should use a fuse block and negative busbar instead. Ensure the battery terminals are clean before connecting any cable lugs to them. Stack cable lugs on the battery terminals in order from heaviest draw (thickest cables) to lightest draw (thinnest cables). Lugs connected to the thickest cables should be positioned at the bottom and the thinnest at the top. Where possible, make use of insulating terminal boots and lug protectors. Ensure all termination lugs are well crimped (not soldered) and protected. Always use the spring washers provided for the battery terminal bolts. This ensures sufficient pressure is applied to the cable lugs for secure connection without having to over-tighten the bolts. Stack the spring washer on top of the cable lugs, not underneath.
9
SETUP AND STORAGE
CONNECTION – MULTIPLE BATTERIES IN PARALLEL You may connect up to six (6) of these batteries in parallel. This will create a single system in which the total capacity is the sum of the capacities of the individual units and the nominal voltage is equivalent to the voltage of one unit e.g. 6 x 200Ah 12.8V batteries in parallel gives a 1200Ah 12.8V system. When connecting batteries in parallel, you should use appropriately rated busbars and connect the batteries as per the below diagram. If connected in this way, the maximum discharge current of the system will be the maximum discharge of a single battery multiplied by the number of batteries in the bank e.g. six batteries connected in parallel will yield up to 100A per hour x 6 = 1200A per hour.
WARNING You must make sure to use cables that are the correct gauge for the maximum discharge current in your application – consult an auto electrician if you are unsure which cable gauge to select. The cables must also be exactly the same length.

SETUP AND STORAGE
STORAGE, SHIPPING AND DISPOSAL Ensure that the battery is stored in a dry, clean, shaded and well-ventilated environment, at a temperature range that does not exceed the maximum storage temperature stipulated in the specifications table in this manual. Where possible, endeavour to store the battery at around 40-50% state of charge. At no time should the voltage of the stored battery be allowed to drop below 11.5V. Be aware that these batteries will self-discharge at a rate of about 3% per month. We recommend the state of charge is checked regularly and topped up if necessary. If shipping the battery between locations, please be aware that lithium is classified as Class 9 Dangerous Goods. Please ensure you comply with local, national and international (if applicable) regulations for transportation of these goods.
WARNING Lithium batteries must never be disposed of with ordinary refuse, as this can cause fires and significant environmental contamination. Contact an authorised lithium battery recycling facility – you can find these at places such as Battery World, Aldi and Officeworks.

CHARGING
CHARGE METHODS
Lithium batteries need to be charged slightly different to other batteries, to ensure they live a long life and provide maximum capacity.
There are several charging devices you can utilise, but whichever device you choose, it must have a lithium charge profile. Suitable devices include DC-DC chargers, solar panels (with regulator) and AC (mains power) chargers.
For optimum battery longevity, it is recommended that the charging current should be 30% or less of your battery capacity.
WARNING
· DO NOT use a charge profile with a “Pulse” or “Equalisation” stage. This will damage the battery and void the warranty.
· DO NOT charge your battery directly from an alternator or via VSR.
CHARGE METHODS: DC-DC CHARGER
DC-DC chargers allow you to charge a lithium battery from your vehicle’s alternator.
You generally cannot charge a lithium battery directly from a vehicle alternator, because lithium batteries have a very high maximum charge current compared to lead-acid batteries. With nothing to intermediate between the alternator and battery, the battery will draw its maximum charge current from the alternator, which can lead to the alternator overheating and burning out.
A DC-DC charger will act to moderate the flow of current, protecting your alternator from overheating. In addition, they have a multi-stage charging algorithm which will ensure your battery is optimally charged and its service life is maximised.
Some DC-DC chargers also include a second input allowing you to connect a solar panel, and may even be able to prioritise the solar charge method when it detects a panel is connected and providing current.
13
CHARGING
CHARGE METHODS: SOLAR PANEL WITH REGULATOR
12V solar panels harness the energy of the sun to charge your battery. There are many solar panel options on the market, but they can be split into two main categories: fixed and portable.
Fixed solar panels usually have a rigid metal frame. They are designed to be permanently fixed to your vehicle and connected to a regulator or DC-DC charger mounted inside. They are great for charging your vehicle while on the go without consuming current from your alternator.
Portable solar panels (solar blankets, solar mats etc.) are designed to be set up while the vehicle is stationary, such as when you’re at camp. They are usually connected to the battery via a portable regulator.
Either type of solar panel is fine for charging these lithium batteries, but as stated previously it is important to ensure that your regulator has a lithium charge profile to maximise your battery’s service life.
AC CHARGER
If you’re charging up your batteries at home before or after a trip, or if you’re at a powered camp site, you can also use an AC (mains power) battery charger. Mains battery chargers are available as portable devices or can be built into your 12V system. Again, you should make sure that the AC charger you wish to use contains a lithium charge profile.
CAUTION: CHARGING IN SUB-ZERO TEMPERATURES
You must not charge your battery in sub-zero conditions. Doing so will void the warranty. In order to charge in sub-zero conditions, you’ll need to purchase our equivalent 240Ah Lithium Cold Climate Lithium (LiFePO4) Deep Cycle Battery with Bluetooth (HKPBATL240BH).
14
BMS AND REMOTE RESET SWITCH
Your battery comes equipped with an integrated advanced Battery Management System (BMS). The BMS ensures there is an even energy balance between cells and allows up to six of these batteries to be connected in parallel or series.
The BMS contains an intelligent protection circuit module which protects against overcharge, over-discharge, short-circuit and over-temperature, and can shut off power to the battery if required.
It also contains a low-voltage disconnect, which will place the battery into protection mode if it drops below 10.0V. If the low-voltage disconnect is tripped, the battery will not accept a charge until it has been reset.
To reset the battery, you can use the included remote reset switch (pictured below) which connects to the port on top of the battery. The switch can be mounted somewhere in your 12V setup and the cable permanently connected, or you can keep the switch and cable packed away and connected it when required.
To use the switch, simply plug the cable it into the top port (if not permanently connected) and hold down the button for five seconds.
You should now be able to charge the battery as normal.
CAUTION
By continuously tripping the lowvoltage disconnect you may cause damage to sensitive electronic equipment that is attached to the battery such as stereo equipment. This is not covered under the battery warranty.
