Welcome to the next generation of DCDC vehicle battery charging. KickAss has developed and delivered an onboard vehicle charging solution like no other. Engineered for durability and expertly designed for charging performance, the KickAss DC-DC charger is the new weapon of choice in dual battery systems.

KickAss DC charging at a glance:

The True 4-stage charging features BULK, ABSORPTION, FLOAT and PULSE modes with advanced algorithms enhancing the overall charging performance of auxiliary batteries. This ensures your auxiliary battery is charged the correct way enabling it to reach maximum charge capacity while also maintaining the battery to its optimum. When coupled with the powerful 25 Amp maximum output capability, it provides exceptionally fast and effective charging.

This charger eliminates the issues associated with smart charging systems and variable voltage alternators in modern vehicles, as it provides a consistent charge output to the auxiliary battery. It provides the reliable charging output required to charge, maintain and and prolong the life of your auxiliary battery, in new and old vehicles.

Inbuilt isolation prevents your auxiliary battery from draining your start battery when your vehicle is not running or charging. The smart tech of our charger detects the charging status automatically, so you never need to worry about engaging or isolating batteries manually, it’s all managed for you from the moment you turn the key.

KickAss DCDC Features

Three Pin Anderson Style Connector

Take the hassle out of connecting your 12V DCDC Charger with the new three-pin Anderson Connection. Run your positive alternator, negative ground and ignition wires together with the new three-pin Anderson connection. Fully Compatible with common two-pin Anderson style connectors.

Lithium BMS Sleep Mode Recovery Feature

When in Lithium Mode and the voltage drops below the safety parameters and the Lithium battery enters sleep mode, the DC-DC charger will begin recovery mode. The DC-DC will trickle charge the battery until it reaches the cut-in voltage and will start normal charging cycles. Most Lithium batteries are built with a Battery Management System (BMS) inside to protect the battery from overcharging, 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 charger has a lithium battery recovery function. This function has been designed to recover lithium batteries from sleep mode. Lithium battery sleep mode indication: when the lithium battery has entered sleep mode, the charger will show fault codes of the output open circuit until all loads are disconnected and a sufficient charge source is connected

You must select 'LITHIUM' as the battery type by using the 'MODE' button prior to connecting it to a lithium battery in sleep mode to attempt recovery.

How to wake a lithium battery to begin recovery mode:

1. Disconnect any load connected to the lithium battery

2. Connect alternator input or solar input to the KickAss DCDC MPPT Solar Battery Charger.

3. Connect the output from the DCDC Charger to the lithium battery

4. The charger will have all battery types flashing and the BULK and PULSE LED lights will remain on for 30 seconds before entering Recovery Mode

5. When the lithium battery has entered recovery mode, the KickAss DCDC MPPT Solar Battery Charger display will have the source indicator illuminated (eg: Solar) and the battery type LITHIUM will be flashing

6. When the battery voltage has been recovered, the DCDC charger will automatically change to normal stage charging and programs and loads may be reconnected
