Upgrading the firmware on the HTRC T240 Duo is a significant step toward modernizing its performance and ensuring it remains a reliable tool for RC enthusiasts. While the T240 is celebrated for its 3.2-inch color touch screen and dual-channel capability, keeping the software current is essential for safety, accuracy, and compatibility with newer battery technologies like LiHV. Why Update? Key Benefits of the New Firmware
Updating to the latest version transforms a standard charger into a more precise and feature-rich device:
Expanded Battery Support: New firmware often adds support for high-voltage lithium (LiHV) batteries, allowing you to charge up to 4.35V per cell.
Safety Patches: Updates often address critical stability issues. For instance, recent reports have highlighted fire risks in some HTRC models due to monitoring bugs; firmware updates can improve voltage detection accuracy to mitigate these risks.
Calibration Retention: Many users have reported that older versions lose calibration settings after a power cycle. Newer firmware aims to fix this memory storage issue, ensuring your 4.20V4.20 cap V remains a true 4.20V4.20 cap V every time.
Enhanced UI & Metrics: Updates typically provide more detailed data, such as individual cell internal resistance and improved graphical status displays. Comparison: Stock vs. Updated Firmware Feature Stock Firmware (Older) Updated Firmware (Better/New) LiHV Support Often missing or limited Full support ( 4.35V4.35 cap V per cell) Calibration May reset after power-off Persistent and more accurate Data Monitoring Basic voltage/capacity Cell resistance & advanced graphs UI Stability Occasional touch-screen lag Optimized touch response Step-by-Step Update Guide
Updating the firmware is straightforward but requires careful attention. Do not unplug the charger during the update process.

HTRC T240 Duo is a dual-channel balance charger and discharger capable of simultaneous charging of two different battery types. While product documentation lists a "firmware update" feature, recent reports from early 2026 indicate a voluntary recall for the T240 and C240 models due to fire hazards. Critical Product Alert: 2026 Recall March 2, 2026
, Shenzhen Haitan Technology Co. (HTRC) has issued a recall for the battery chargers.
The chargers may ignite or cause connected batteries to ignite, posing risks of injury or death. Consumers are advised to seek a For support in the U.S. and Canada, call toll-free at 327-208-2365 (5 p.m. to 2 a.m. UTC, Mon–Fri) or visit the official HTRC contact page Reported Technical Issues & Firmware Limitations
Before the recall, users reported several persistent bugs that firmware updates were intended to address: Calibration Loss:
A common issue where manual voltage calibrations are lost every time the unit is powered off, potentially leading to overcharging. Voltage Accuracy:
Users reported discrepancies where the display showed 4.20V while actual cell measurements reached dangerous levels of 4.22V to 4.28V Cell Identification:
Some units failed to automatically detect cell counts correctly, which led to battery damage. Firmware Access: Although a "Software download" section exists on the HTRC Download site
, users frequently found official links for the T240 firmware were broken or difficult to access. Hardware Features (Standard Model)
If you are currently evaluating your unit, these are the standard technical specifications: HTRC 240 Dual Charger Recall Thoughts
HTRC T240 Duo is officially marketed as supporting firmware updates to enhance performance, but users often face significant technical hurdles and severe safety warnings
that complicate the process. While newer firmware versions aim to fix "annoying bugs" like voltage calibration loss, the actual procedure is frequently hindered by driver recognition issues. The Firmware Reality: Hopes vs. Hurdles Intended Improvements : Firmware updates are designed to refine the 3.2-inch color touchscreen interface, fix automatic cell count detection errors, and stabilize Terminal Voltage Control (TVC) Common Technical Failures Improved Performance : The update optimizes the device's
: Many users report that when attempting to update, computers fail to recognize the charger as a USB device, even with the manufacturer's recommended drivers installed. Calibration Persistence
: A recurring issue in older firmware is the charger's inability to "save" calibration settings. Users find that after manual recalibration, the settings are lost once the power is cycled, potentially leading to overcharged LiPo batteries (e.g., cells reaching 4.23 cap V while the display incorrectly shows 4.20 cap V Critical Safety Warning & Recalls late 2024 and 2025
, severe safety concerns have overshadowed minor firmware tweaks: Fire Hazards
: The U.S. Consumer Product Safety Commission (CPSC) issued a high-priority warning to immediately stop using HTRC C240 chargers
(a sister model to the T240) due to reports of units overheating and igniting. Widespread Incidents 148 reports of fire or thermal incidents have been linked to various HTRC products. Recall Status
: A massive recall was initiated for over 34,000 units sold through major retailers like AliExpress How to Proceed (If You Still Choose to Update)

Unlike smart chargers from ISDT or HOTA, the HTRC T240 DUO does not support USB or Bluetooth updates. Updating the firmware requires:
This is not a casual process. HTRC officially recommends that only users experiencing the specific “low input voltage” bug attempt the update. For everyone else, they advise shipping the unit to a regional service center for a free firmware flash (you pay shipping one way).
Old firmware often showed "N/A" or wildly fluctuating IR values (e.g., a healthy battery showing 20mOhms). The new update calibrates the zero-point reference.
The HTRC T240 Duo is already a favorite among hobbyists for its dual-channel output and reliable performance. However, like many smart chargers, the hardware is only as good as the software running it. HTRC has recently pushed out a significant firmware update that addresses user feedback and smooths out the rough edges of the user interface.
If you have been frustrated by button responsiveness or confusing menus, the "new" firmware is the fix you’ve been waiting for.
