Capable of charging two batteries simultaneously, regardless of chemistry or capacity, the RDX2 200 allows you to connect different battery chemistries (NiMH/NiCd/LiPo/LiFe/Lilo/LiHV/Pb) into any of the two charging ports (100W per port, 200W total power) and features integrated balancing for 6-cell LiPo batteries.
Designed with an easy-to-read LCD screen and sleek metal scroll wheel for simple setting selection, this twin-channel charger is also compatible with Hitec’s “Charge Master” PC software & "Charge Manager" Mac software that allows charger operation and firmware updates from a personal computer. Whether you run sport-level 1/10th and 1/8th scale electric vehicles, 600+ size helicopters, or sport and giant-scale planes using up to 6S batteries, the RDX2 200 is the compact, affordable charging option for your hobby!
Two XT60-to-XT30 output adaptor cables are included.
Features:
- User-Friendly Interface
- Balance, Standard, Storage and Cycle Modes for All Lithium Battery Chemistries

Internal Resistance in FTC
One of the reasons this charger is “smart” is that it can tell you the internal resistance (IR) of a battery. A battery’s IR increases over time, and batteries with a higher IR are likely to reduce a robot's performance. Competitors in the First Tech Challenge (FTC) can use their knowledge of a battery’s IR to evaluate if that battery is still ready for the ring or if it should be relegated to practice.
The effect of batteries’ IR values on robot performance is clarified by a small, but essential, piece of electrical theory. Voltage is calculated by multiplying current by the resistance (Ohm’s Law, written as voltage = current X resistance). As a result of this relationship, when a robot draws current, the IR will cause the voltage drop. Higher IR values produce greater drops in voltage, and voltage drops result in reduced performance.
