OPTIONAL ACCESSORIES

CONNECTING THE BATTERY

Install the battery cables onto the terminal posts of the battery. Ensure the red cable is connected to the positive (+) terminal and the black cable is connected to the negative (-) terminal.
If connecting the Remote Display Unit to your KickAss Lithium Battery, connect the black data dongle on the RDU to the black data connector on the battery.

CHARGING THE BATTERY

A key function of the BMS is to protect your battery by internally disconnecting the load when the battery’s voltage drops below specific parameters, this will then result in the battery entering into a “sleep” mode. (Load includes any accessories and/or device/s drawing charge from the battery, Eg: fridges, pumps, food sealers, inverters, etc). The  harger used to charge the battery must be lithium compatible and be designed to recover lithium batteries from a sleep mode. The KickAss Lithium Battery may be
charged in a number of ways:

• Connecting to an alternator via a lithium-compatible DCDC charger.
• Connecting to a solar panel via a lithium-compatible regulator/controller
• Connecting to an AC power source via a 240V lithium compatible 12V charger

Note: When charging the lithium battery, ensure the charger is located close to the battery to avoid voltage drop. Failing to do this may result in the charger entering float mode prior to the battery reaching 100% SOC.

STORING THE BATTERY

A lithium battery can be stored at any state of charge due to a very low rate of discharge. It is recommended that if stored for long periods, the battery be charged to 100% before disconnecting the battery from all loads and chargers.
NOTE: The battery will not go into storage mode if:

• There are loads connected to it
• It is being charged
• The RDU’s screen is turned on
•  It is communicating to App.

USING THE BATTERY FOR THE FIRST TIME OR AFTER A PERIOD OF STORAGE
When using the lithium battery for the first time or after more than a month in storage, KickAss recommends fully discharging the battery until the BMS system cuts out. Once discharged, using a lithium-compatible charger, fully charge the battery until 100% SOC is achieved. This will recalibrate the SOC in your BMS.
Failure to do these steps will not affect the performance or lifespan of your battery however the SOC reading from the Display screen or App may not display the actual SOC of the battery due to it being out of synchronization.

STEP 1:
Connect the load and discharge until the Undervoltage alarm is activated
Note: Continue to discharge when the low battery alarm comes on at 10% SOC.Doing this will NOT damage your  attery
STEP 2:
Connect the battery to charger and charge to 100%

KICKASS LITHIUM APP

The KickAss Lithium Battery has been designed with the latest Bluetooth technology to remotely monitor your battery from your smartphone. The app features the following:

• State of Charge (SOC)
• Instantaneous current flow, positive when charging, negative when discharging
• Battery pack and cell voltage.
• Battery temperature
• Remaining time to full/empty at the current rate of charge/discharge
• The total capacity of the battery
• A number of full cycles the battery has completed. A full cycle is defined by 100% discharge and re-charge of a battery. Depleting a battery to 50% and recharging it twice will result in 1 cycle.
• Low battery alarm
• Battery capacity health indicator
• Battery protection alarms
  

Connecting to the App
To get started please download the KA Outback Proof Gear app from the Google Play store or the Apple iTunes Store.
If the app is already downloaded on your device for use with your KickAss Bluetooth fridge, you must ensure that any updates to the app are installed prior to connecting. Once the APP is installed, locate your battery’s serial number on the side of your battery. On the KA Outback Proof Gear app, find the device ID that corresponds to the first  10 digits and the last 4 digits of the battery’s serial number and click connect the device.

Rename Device ID
To rename your Bluetooth device, connect to the device and then navigate to the fourth tab on the bottom toolbar. Click the pencil icon next to the connected device, edit the name and then click Save.
Note: Editing your device’s name, will only edit it on your device. It will not change the name of the battery for other people who try to connect to it.
