- Selectable charge rates range from 25mA to 20A
- Continuous maximum output power rating, 500W @ +24VDC input voltage, 250W @ +12VDC input voltage
- Native support of JST XH balance connectors allows direct connection of 1s-8s LiPo/LiHV Batteries without requiring any adapters. Also supports Revolectrix SPA and MPA Safe Parallel Adapters; the industry's safest methods for parallel charging multiple, same-cell-count packs. These items are peripheral products, available separately or as part of Combo packages, not included as a part of the basic GT500 unit.
- Smart power management allows customer to select between programmable input power sources. Available settings include power supply input current limit, input low voltage limit, regenerative discharge rate and voltage limit. GT500 stores 1 set-up for Power Supply and 1 set-up for Battery and can be programmed to ask for verification one time on start-up
- GT500 supports charging through the main discharge wires only for certain scenarios (see features tab for full details). For balanced charging, the unit requires balance wires in combination with the discharge wires. (charge rate support up to 20A max)
- Initiate charge, discharge, store, monitor, and multiple cycles at the GT500.
- The unit comes equipped with basic presets for all battery chemistries currently available as well as 28 EMPTY user preset positions. During the course of operation, any changes that are made at the charger may be named and saved ("SAVE AS") or saved over ("SAVE") to the user presets bank. The process is analogous to opening a document in a PC application, making changes, and then using the "Save" or "Save As" menu options from the PC application to store the unique setup parameters chosen during the course of using the charger for its intended purpose; charging and managing your batteries. Best of all, everything happens at the charger, which makes it ideal for taking it on the road.
- 0.1mohm voltage resolution allows accurate four point internal resistance measurement of each cell
- Environmentally friendly, regenerative discharge capability of up to 500W. Unlike traditional methods of discharge, which deplete the output battery's energy in the form of heat across a transistor, regenerative discharge takes most of that energy and puts it back into the input battery. In other words, when you discharge your LiPo for storage, you will be re-charging your Lead Acid input battery. The total amount of power that you can achieve is limited only by the amount of current that your input battery can accept, or 500W, whichever is lower.
- GT500 is also equipped with a traditional, 50W internal discharge capability which is non-regenerative.
- Massive over-sized internal heat sink
- 12AWG silicon input power cable terminating in an EC-5 female pin connector. A plier clip assembly with EC-5 on one end and red/black plier clips on the other is available as an accessory item.
- Massive sendust core toroid capable of 25A continuous input current requirement for maximum output specifications
- 2.6", 128 x 64 pixels graphic LCD with white LED backlight
- Embedded PC USB support and free PC Software
- Intuitive Navigation Wheel with inclusive push button SELECT/ENTER, plus a BACK button makes Navigating menus and making selections a joy!
- Sleek and attractive high-impact ABS enclosure for maximum airflow efficiency
- Sturdy Aluminum top panel
- Quick "preset over-ride access" to common charging parameters like setting charge and discharge current and operational modes of charge / discharge / monitor / cycle(s)
- Additional advanced options menu for adjusting in-depth charging parameters and global options at the unit
- Free and reliable firmware updates for the life of the product using the free, downloadable, Windows-based Firmware Update Utility (Application)
- Programmable options allow speaker ON/OFF or volume, selectable completion notification, information scrolling, Logo display duration at power up and Navigation Wheel direction control.
- Multiple product cases can be interlocked
