WARNINGS
- To avoid injury or damage to your vehicle ensure the instructions are read carefully and understood.
- Batteries can produce harmful vapour and explosive gases when being charged.
- Ensure batteries are mounted and stored in an area with good ventilation.
- 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:
-
Can charge multiple battery types:
Compatible with GEL, AGM, WET, CALCIUM or Lithium LiFePO4. -
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. -
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. -
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.
Stay safe and protect your assets with these protective features:
-
Short circuit protection
The Charger will not turn on unless the batteries are connected correctly. -
Reverse polarity protection
If you connect positive and negative the wrong way around the Charger will show a fault. -
Over voltage protection
If the Charger detects voltages connected to its inputs or outputs that are too high it will shut down. -
Over temperature protection
The Charger will lower its output current if it senses that the unit will overheat. -
Temperature compensation:
The included temperature sensor will measure the battery temperature and adjust current accordingly to prevent overcharging.

PRODUCT OVERVIEW
INSTALLATION GUIDE
SAFETY FIRST!
- The KickAss Charger has been engineered to charge 12 Volt GEL, AGM, WET, CALCIUM or Lithium LiFePO only. Do not use this charger for any other purpose or 4 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
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.
WIRING SIZE
To make sound electrical connections, the battery cable should be the correct
size and the correct terminals should be crimped or soldered.
CABLE SIZING
The table below outlining the required cable size for a given install length.
Please refer to this table for Vehicle Input, Solar Input, Ground and Battery
Output cable thickness requirements. Always choose a wire cross sectional area
equal to or greater than what is specified below.
Note:
- Always use a fuse in-line for all connections to the starter and aux battery!
- The input and output negative cables labeled Ground 3 and Ground 2 should be connected at the battery negative poles for improved performance.

CHOOSING THE BATTERY TYPE
The battery type setting must be confirmed during device installation. When the auxiliary battery is connected, 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 The selected battery type will be saved as the new default.
CHARGING STAGE PROFILE
NOTE:
When in FLOAT stage, the battery is fully charged. At float stage, when the
battery voltage drops to 0.3V below the specified float voltage for the
battery type connected, the charger will restart charging form the BULK stage.
UNDERSTANDING SOLAR, ALTERNATOR & CHARGING LIGHTS
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 load¹ when voltage drops below specific parameters, this
will then result in the battery entering into a “sleep” mode.
¹ (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
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

FAULT CODES
If the fault light is flashing, please refer to the fault codes below for
diagnostics.
Note : Only the selected battery type LED will flash when the device
detects a fault condition
