Lithium Battery Charger

Ardent 12V 20A Lithium Charger

Features a trickle charge mode that will protect the battery. This charger will increase lithium battery cell reliability and performance. It also prevents your lithium battery from overcharging with three-stage charging modes: constant current, constant voltage, and trickle (or float charge). This charger has a 3-stage intelligent charging design: high current (cc), constant voltage (cv), and trickle. Moreover, this Ardent LiFePO4 battery charger can balance the cells of the battery pack, which is necessary to prevent cells from draining faster than others during charging, thereby avoiding the risk of cell damage.This LiFePO4 battery charger has advanced features such as built-in temperature sensors, which allow the charger to adjust the charging current according to the battery temperature, ensuring optimum performance and prolonging the battery lifespan.

This Ardent Battery Charger can accurately identify battery voltage and automatically switch charging mode and provide fast and efficient charging for lithium batteries.

12V Lithium Battery Charger

These chargers are specifically designed to charge LiFePO4 batteries with the correct voltage, current, and charging algorithm, ensuring that the batteries are protected from overcharging and undercharging. Battery charging is when you are requiring to recharge a flat or dead battery to full. Battery maintenance on the other hand is when you just want to keep a battery topped up. For instance, if you're storing a classic car that you only drive a few times a month but want to ensure it's ready to go on a sunny afternoon you would require battery maintenance as opposed to battery charging. This is often referred to as trickle charging a battery. All ARDENT lithium battery chargers perform both functions.

Perfect for Use in a Range of Power Applications

This battery charger is designed for lithium batteries. When the lithium battery triggers the low temperature/low voltage while charging, the BMS will turn on the protection, which means the lithium battery cannot be charged and needs to be activated. This charger provides a lithium battery activation function that quickly exits the protection mode and recharges. Along with Australian CE  certification, it provides a safe and stable AC charging environment.

Power Up Your Lithium Battery with a 240V AC Lithium Charger

This battery charger has a wide AC input voltage range, 100-240 VAC 50/60Hz, which is compatible with various needs. The charger comes with an Anderson Plug charging cable cable which is designed to allows users to quickly establish the connection between the battery and the charger. ARDENT lithium battery chargers are based on a CV/CC (constant voltage/constant current) charge algorithm. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level. The current then reduces as the battery becomes fully charged. This system allows fast charging without the risk of over-charging and is suitable for Lithium Iron and other battery types. Ultimately, using an ARDENT battery charger with a specific Lithium charge algorithm is the best option for maximum performance and lifespan of any lithium battery.

Ardent 12V 20A Lithium ​LiFePO4 Battery Charger

For a 12V system, we really want to emphasize reaching 14.2V – 14.6V for bulk and absorption and float to be 13.6V or lower. 

  • Battery Type: Lithium battery
  • Output parameter - 14.6V
  • Charging current 20(A)
  • Dimensions 170×90×50 (mm)
  • Shell material: Aluminum Shell
  • Working temperature: -5℃ ~ +40℃
  • Storage temperature: -40℃ ~ +70℃

12V Deep Cycle batteries, you should set your charger profile to charge up to 14.6 volts for 30 minutes and then float charge at 13.6 volts. For a 12V system, we really want to emphasize reaching 14.2V – 14.6V for bulk and absorption and float to be 13.8V or lower.  That means a 12-volt lithium battery will boast a normal maximum voltage of 13.6 volts when fully charged. And even after discharging 10% of their nominal capacity, they still have 13.4 volts at resting voltage (a loss of only 0.2 volts). ***Note that all 12V batteries above 12Ah, configured in Series, must be charged individually with a 12V charger.
