ProTek R/C Prodigy 620 DUO Charger

ProTek R/C Prodigy 620 DUO Charger

This charger is packed with great features like a two independent 400 Watt channels, a backlit LCD display, balance ports, sensor ports, and more. Check out all the details in the press release below:

A Main Hobbies announces the newest ProTek R/C charger, the Prodigy 620 DUO. There is no such thing as too much power and the Prodigy 620 DUO is an impressive charger that has the power you need to get your batteries charged quickly, with the features, reliability, and customer support you have come to expect from ProTek R/C!

The Prodigy 620 DUO features two independent 400 Watt channels, each with its own control panel, LCD display, balance ports and sensor ports. Plus, each channel has its own blue backlit LCD display with white characters to provide clear visibility in any environment.

Additionally, the Prodigy 620 DUO can charge LiPo, LiFe, or Li-Ion batteries up to 6S, 15-cell NiCd or NiMH batteries, and lead-acid batteries up to 20V. With the ability to fast charge, balance charge, and storage charge lithium cells, you can easily tailor the charge process to suit your needs, while individual cell voltage can be monitored during balance mode charging, allowing you to identify an imbalance in the cells and spot a weak cell before it becomes a problem. Other features include a dual-fan cooling system that utilizes a push-pull design that will keep the charger cool, even when working at maximum capacity. Plus it’s backed by ProTek R/C’s legendary customer support, so no matter what your charging needs may be, the Prodigy 620 DUO has you covered.

  • Optimized Operating Software: An optimized “Auto” function controls the charge rate during the charging and discharging process. This will help to prevent damage due to user error. If there is a malfunction, the circuit will be disconnected automatically and an alarm will sound. All operating modes are controlled through a two-way communication process between the charger and the battery in order to maintain maximum safety, and all settings can be configured by the user.
  • Internal Lithium Battery Balancer: Each channel features an individual cell voltage balancer. An external balancer is not required for balance charging.
  • Individual Cell Discharge Balancing: When discharging, each cell is monitored and balanced individually. If the voltage of any cell is abnormal, an error message will be displayed and the process will be terminated.
  • Lithium Battery Adaptability: Compatible with the three most common Lithium battery types: LiPo, Li-ion, and LiFe.
  • Multiple Lithium Battery Charge Modes: Programming allows Fast Charge, Balance Charge or Storage Charge Modes for LiPo, Li-ion, and LiFe batteries.
  • “Fast” Charge Mode: Reduces charging time, but does not balance the cells and charges the battery to approximately 90% capacity.
  • “Balance” Charge Mode: Monitors individual cell voltage, keeps the cells within an acceptable voltage range and charges the pack to peak capacity.
  • “Storage” Charge Mode: Used for long-term battery storage. Adjusts the voltage level so the battery will not be damaged during storage.
  • Maximum Safety Through Delta-Peak Technology: The automatic charge termination program uses Delta-Peak voltage detection. When the battery’s voltage exceeds the threshold, the process will be terminated automatically.
  • Automatic Charging Current Limit: The upper limit of the charge current can be set for charging NiCd or NiMH batteries. This is useful for NiMH batteries with low resistance and capacity in the ‘AUTO’ charging mode.
  • Capacity Limit: The charging capacity is always calculated as the charging current multiplied by time. If the charging capacity exceeds the limit, the process will be terminated automatically when the charger reaches the maximum value.
  • Temperature Threshold: The batteries internal chemical reaction can cause the temperature of the battery to rise during charging. If the temperature limit is reached, the charging process will be terminated. This function is only available when using the temperature probe and its parameters are user-specified.
  • Processing Time Limit: The user can set the maximum charging time. If the charging time exceeds the limit, the process will be terminated automatically.
  • 10 User Presets: Customize 10 individual presets, each with different parameters set for a particular battery type. This allows the user to “call up” the settings for a particular battery without additional programming needed.
  • Cyclic Charging/Discharging: Batteries can be set Charge/Discharge or Discharge/Charge for up to 5 cycles.
