WARNINGS
Y To avoid injury or damage to your vehicle ensure the instructions are read carefully and understood.
Y Batteries can produce harmful vapour and explosive gases when being charged.
Y Ensure batteries are mounted and stored in an area with good ventilation. Y As this Charger has powerful output current, circuit protection such as fuses or
circuit breakers must be installed as near as possible to the batteries - refer to wiring diagrams in this manual for correct fitting. This manual will give you all of the essential information you need to own and operate your new KickAss 20/40A DCDC Charger with MPPT Solar Controller.
The purpose & features of the KickAss 20/40A DCDC Charger with MPPT Solar Controller:
u Can charge multiple battery types: Compatible with GEL, AGM, WET, CALCIUM or Lithium LiFePO4.
u Prevent your auxiliary battery from draining your start battery: Built-in voltage sensing will ensure your start battery charges your auxiliary battery when the vehicle is running. It will then disconnect the start battery from the auxiliary battery when the vehicle is not running.
u Ensure your auxiliary battery is being fully charged and maintained: Most modern vehicles (especially those manufactured after 2010) do not provide the correct voltages and charge control to safely and completely charge your auxiliary battery. The Charger overcomes this issue by boosting the charge voltage to an optimal output level while ensuring your auxiliary battery is safely charged via its multi-stage charge algorithm.
u When your vehicle is not charging, charge from the built-in MPPT solar controller: Maximum power point tracking is the most efficient type of solar controller and allows you obtain the maximum amount of charge from your solar panels. When your vehicle is not doing the charging, the built-in MPPT solar controller will let your solar panels do the work.

INSTALLATION GUIDE
SAFETY FIRST!
,, The KickAss Charger has been engineered to charge 12 Volt GEL, AGM, WET, CALCIUM or Lithium LiFePO4 only. Do not use this charger for any other purpose or with any other battery types.
,, Do not attempt to charge known faulty, damaged, frozen or broken batteries. ,, Ensure charger is close to battery, however never mount the charger directly on the
battery. ,, Ventilation is very important in battery charging, always ensure battery positioning is
in a well ventilated area to allow charging gases to dissipate. ,, Keep sparks or flames away from batteries being charged as they could emit
explosive gases. ,, Always check the batteries and charging system periodically to ensure no faults
occur. ,, Ensure all cabling is secure and cannot be cut, broken or short circuited. ,, Battery acid is corrosive. If acid comes into contact with skin or eyes, please seek
medical advice. ,, Never connect this charger to mains supply. ,, We recommend fitting a 50-75 amp fuse on both the input and output sides of the
charger such as the SKU: KAMAXIFHAND or SKU: KAFUSECOVER-KIT to protect cables from short circuits etc.
MOUNTING
It is most important to mount your KickAss Charger as close as possible to your auxiliary battery and be sure to keep your charger away from sources of heat. eg. Turbos and exhaust pipes. This will ensure maximum performance out of your charger.

UNDERSTANDING SOLAR, ALTERNATOR & CHARGING LIGHTS

Standby Mode No inputs detected. Once the Aux battery has been connected and is within the detectable voltage range, the battery type LED will short flash to indicate the device is in standby mode and no input sources are detected

12V 20A

Battery type selection mode Press and hold the Mode button for 2 ~ 4 seconds, upon releasing the button, the battery type LED will move to the next position. Repeat the steps until required battery type LED is selected. Battery type setting is now programed and charger will return to Standby mode after a short time.

12V 20A

Standby Mode Alternator input detected With no Solar connected or detected and the Alternator is the only available input source, the input LED will short flash to indicate input voltage is below the set cut-in voltage. Charger is still in Standby mode and has not begun to charge the battery.
Standby Mode Alternator and Solar inputs detected Both input sources are detected but neither has reached the set cut in voltage range. By default Alternator input has priority and will provide power to charge the battery. Solar priority has not been selected and indicator LED is on.

12V 20A 12V 20A

Charging with Alternator or Solar only Once the input source reaches the set cut-in voltage, charging will begin. The battery type LED will turn solid and the active charge stage LED will come on and remain solid, while the input source LED will continue to flash.

Charging with Alternator as priority (default) Once the Alternator input voltage reaches the set cut-in voltage, charging can begin. The battery type LED will turn solid and the active charge stage LED will come on and remain solid, while the input source LED will continue to flash. Solar input LED will remain solid while source is available. The charger will transition through the different charging stages as previously shown, until the battery is full.

12V 20A

Charging with Solar as priority - Setting Solar Priority mode The function of Solar Priority mode is to allow the charger to check for available solar input before choosing the alternator as the input source. To do this, the charger will assess the state of charge of the battery and decide if the available solar can effectively supply enough charge or choose the alternator as the best input source. The Solar Priority function can be set at any time, once the Aux battery has been connected. To set Solar Priority, press and hold Solar Priority button for 2 ~ 4 seconds, then realse the button, to change the priority . The Solar Priority indicator LED will start to flash.

Lithium BMS Sleep Mode & Recovery Feature: Most lithium batteries are built with a Battery Management System (BMS) inside to protect the battery from over charging, over discharging and extreme temperature changes. One of the key functions of the BMS is to protect your battery by internally disconnecting the load� when 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, etc) The KickAss DCDC MPPT Solar Battery Controller has a lithium battery recovery function. This function has been designed to recover lithium batteries from a sleep mode. Lithium Battery Recovery Mode Procedure First disconnect any load connected to the lithium battery. Secondly connect Alternator Input or Solar Input to the KickAss DCDC Charger with MPPT Solar Controller. Thirdly connect the output from the DCDC charger to the lithium battery. When the DCDC Charger with MPPT Solar Controller input charging voltage reaches the relevant cut in voltage, the DCDC Charger with MPPT Solar Controller will automatically try to activate the battery every minute. When DCDC Charger with MPPT Solar Controller attempts to activate the battery, if a open-circuit or short-circuit error is detected, the DCDC Charger with MPPT Solar Controller will enter standby mode until the next activation attempt. If the activation attempt is successful, DCDC Charger with MPPT Solar Controller will initiate the regular three stage charging sequence. Once the DCDC Charger with MPPT Solar Controller indicates the battery has reach the FLOAT charge state, the battery has been fully recovered and loads reconnected.
