HTRC C240 DUO AC 100-240V DC 11-18 V LiPo LiFe / Li-ion/NiCd/NiMH/Pb Multi Charger/Discharger

The HTRC C240 DUO is a professional-grade dual-channel battery charger and discharger designed for RC hobbyists, drone operators, and electronics technicians who require simultaneous charging and discharging of multiple battery chemistries. This intelligent charger supports LiPo, LiFe, Li-ion, NiCd, NiMH, and Pb batteries with independent channel control, eliminating the need for multiple chargers in your workshop. The C240 DUO solves the critical problem of battery conditioning, capacity testing, and safe charging of diverse battery types with precision current control and real-time monitoring.

Product Overview

The HTRC C240 DUO operates on universal AC input voltage ranging from 100-240V, making it suitable for global use and laboratory environments. Each of the two independent channels can deliver DC output between 11-18V, allowing simultaneous charging or discharging of two batteries without interference. The charger employs advanced microprocessor-controlled technology with automatic cell detection, which identifies battery chemistry and cell count automatically, then applies the optimal charging algorithm. This prevents overcharging, over-discharging, and thermal runaway conditions that commonly damage expensive battery packs. The dual-channel architecture enables professionals to maintain battery capacity logs, perform cycle testing, and balance cell voltages across multi-cell packs with precision.

The C240 DUO features independent current and voltage adjustment for each channel, with typical charge rates ranging from 0.1A to 10A per channel depending on battery capacity and chemistry. The integrated LCD display on each channel provides real-time monitoring of voltage, current, capacity, time elapsed, and battery status. Safety features include reverse polarity protection, short-circuit detection, temperature monitoring with automatic shutdown, and timer-based cutoff to prevent unattended charging hazards. The charger supports both CC-CV (constant current-constant voltage) charging for lithium batteries and smart pulse charging for NiMH/NiCd batteries, making it indispensable for RC car racing teams, drone maintenance crews, and electronics repair shops.

How to Use

Begin by connecting the HTRC C240 DUO to a stable AC power source between 100-240V. Insert the battery connector into the appropriate port on either channel, ensuring correct polarity alignment. Press the power button to activate the channel and use the menu buttons to select battery chemistry from the options: LiPo, LiFe, Li-ion, NiCd, NiMH, or Pb. The charger will auto-detect cell count and display the configuration on the LCD screen. Adjust the charge current using the up/down buttons based on your battery capacity (typically 1C rate is recommended, meaning 1A per 1000mAh capacity). Press start to begin charging. The LCD will display real-time voltage, current, capacity accumulated, and estimated time remaining. The charger automatically stops when the battery reaches full charge or when the current drops below the threshold for the selected chemistry.

For discharging operations, select the discharge function from the menu after selecting battery chemistry. Set the discharge current to a safe level (typically 0.5C to 1C rate) and press start. The charger will safely drain the battery while monitoring voltage and temperature. This is essential for capacity testing, battery conditioning before storage, and preparing used batteries for recycling. Never leave the charger unattended during operation. If the temperature sensor detects overheating above 65 degrees Celsius, the charger automatically shuts down. Always use appropriate gauge wiring for your current settings and ensure the power supply can provide sufficient current without voltage sag. Store the charger in a cool, dry location away from moisture and extreme temperatures.

Frequently Asked Questions

Can the HTRC C240 DUO charge different battery types simultaneously on each channel?

Yes, each channel operates independently with its own microprocessor and charging algorithm. You can charge a LiPo battery on Channel 1 while simultaneously discharging a NiMH battery on Channel 2. Simply select the appropriate chemistry for each channel using the menu buttons. This dual-chemistry capability makes the C240 DUO ideal for mixed battery environments like RC clubs and repair shops.

What is the maximum number of cells the HTRC C240 DUO can charge?

The C240 DUO supports cell configurations up to 6S LiPo (22.2V nominal) and 8S LiFe (24V nominal) within the 11-18V DC output range. The charger auto-detects cell count and applies appropriate cell balancing. For higher cell counts, you would need a higher voltage charger model. Always verify your battery configuration before connecting to prevent damage.

Is the HTRC C240 DUO suitable for charging intelligent batteries with built-in management systems?

Yes, the C240 DUO is fully compatible with intelligent batteries such as DJI Intelligent Flight Batteries and other smart packs with onboard BMS (Battery Management System). The charger communicates with the BMS through the connector and applies appropriate charging profiles. The independent LCD display will show battery status information transmitted by the intelligent battery. This makes it ideal for professional drone operators who need to maintain multiple smart batteries.
