## Description

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
- Battery Resistance Meter
- Terminal Voltage Control
- Re-Peak Charge Mode and Delta-Peak Sensitivity for NiMH/NiCd Batteries
- Capacity Cut-Off Limit
- Smart Ventilation Fan
- Built-in Power Supply Function for Powering Devices up to 27V @ 10A

### 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.
