Revolectrix GT500DUO, Multi-Chemistry, 1000W Charger with MPA Boards

Part Number: LCGT500DUO-EC5-MC

Welcome to GT500DUO, the first dual channel offering in the amazing NEW GT SERIES of R/C Battery Chargers from Revolectrix. Built on time-proven, reliable PowerLab hardware, this new 1000W, 1s-8s Charger provides a fresh approach to a more traditional user interface than the PowerLab series at an affordable price. Simplicity is the core thrust of the new user interface, boasting two larger, backlit dot-matrix LCD, allowing access to virtually every relevant parameter required to the routine charging, discharging, monitoring, and cycling of any battery chemistry available while at the same time providing easy-to-read feedback of key information during every operation; bigger screen, more information, easier to read. Adding to the intuitive feel, the new navigation wheel makes for quicker access to various menu options, and includes a SELECT/ENTER button. A separate BACK button rounds out the interface to allow the user to "back out" of menus and return to previous screens.

The Cellpro GT500DUO Charger directly supports balance charge of any 1s-8s LiPo or LiHV battery pack equipped with a JST XH balance connector on each channel without the use of an adapter. It also directly supports the Revolectrix MPA and SPA Smart Parallel Adapters; the safest parallel charging solutions on the market. Look for the MPA Combo in the REVO webstores.

More on the GT SERIES Philosophy (TAKE IT ON THE ROAD):

GT SERIES is all about simplicity and productivity at the field. It is not intended to replace the top-tier PowerLab series, but rather to offer an even simpler approach to common charging scenarios, straight out the box. The user interface is intuitive and instantly familiar, regardless of what charger you are using now. The PowerLab series remains the flagship of the Revolectrix product line; preset-driven with fully-customizable, "open architecture" presets, as well as graphing and data logging. When coupled with the PC Charge Control Software (CCS) the full potential of the Powerlab series can be unleased. In contrast, GT series focus is ease of use as well as preset customization without the need for a PC. However, as with all Revolectrix charging products, the GT series does continue the long-standing ability to effortlessly and reliably update the firmware in the charger. With embedded USB support, connecting to a PC for this purpose has never been easier!

This is not to say that the GT SERIES does not support presets. It does, but in a different, seamless way. 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 down ("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.

Major Features

Selectable charge rates range from 25mA to 20A (per channel)

Continuous maximum output power rating, 1000W @ +24VDC input voltage, 500W @ +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 GT500DUO 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. GT500DUO 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

GT500DUO 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 per channel). When setting up input supply limits, each channel must be set separately.

0.1mohm voltage resolution allows accurate four point internal resistance measurement of each cell

Environmentally friendly, regenerative discharge capability of up to 1000W (total). 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 1000W, whichever is lower.

GT500DUO is also equipped with a traditional, 50W internal discharge capability (per channel) which is non-regenerative.

Large cooling fan

Massive over-sized internal heat sink

12AWG silicon input power cable terminating in an EC-5 female pin connector supplies power to both channels simultaneously. 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
