    Great for maintaining battery charge

    I got this to maintain the battery charge of my hobby car and it does that very well. I can leave it on the car until I want to drive it knowing the battery will be fully charged.

    Great little unit

    Bought this unit to set up as a constant trickle charger for a vehicle that doesn't get used often. A job it does well with the variable amps feature. Have also used it as a conventional battery charger on flat batteries and done the heavy lifting there also. Great value for money.

Frequently Asked Questions

How much current can the KickAss Flexicharge 12V 4A charger deliver when charging my battery?
The KickAss Flexicharge delivers a maximum charging current of 4 amps at 12 volts, with an adjustable output allowing you to select either 1 amp or 4 amps depending on your battery size. This flexibility ensures precise and efficient charging tailored to your battery’s needs.
Can I use this charger with different types of batteries like AGM or lithium?
Yes, the KickAss Flexicharge is compatible with multiple battery chemistries including lead acid, AGM, GEL, and LiFePO4 lithium batteries. It features dedicated charging modes for each type to ensure safe and effective charging.
How do I safely connect and start charging my battery with this charger?
To safely charge your battery, first position the charger near your battery and connect it to AC power. Then select the correct battery type mode, connect the alligator clamps to the battery terminals (red to positive, black to negative), and finally connect the Anderson connector to the charger.
What safety features does the KickAss Flexicharge have to protect me and my battery?
The charger includes reverse polarity protection, short circuit protection, and overheating protection. For example, if clamps are connected incorrectly, the red LED will blink and charging won’t start, preventing damage. If the internal temperature reaches 95°C, the charger reduces current to 2A to avoid overheating.
Can I use the charger to revive an old or unused AGM battery?
Yes, the KickAss Flexicharge features a special AGM Recondition mode designed to deliver a specialised charge to AGM batteries that haven’t been used for some time. This helps restore battery capacity and prolongs battery life.
What are the physical dimensions and operating conditions for this charger?
The charger measures 18.5cm long, 9cm wide, and 5.5cm high, and operates safely within a temperature range of -10ºC to 40ºC. It is designed for indoor use only with input voltage of 220-240V at 50Hz.
How does the charger handle power interruptions during charging?
If mains AC power is disconnected during charging, the charger remembers the current charge settings and automatically resumes charging in the same mode once power is restored, provided the battery clamps remain connected.
What connection options are available for attaching the charger to my battery?
The KickAss Flexicharge offers two connection methods: an Anderson-style connector and alligator clamps. This dual option allows you to easily connect to various battery terminals and setups.
