I've been using the HTRC T240 Duo to charge 4S and 5S LiPo packs for my FPV drones for over 18 months. Before the firmware update, AliExpress htrc t240 duo firmware update - AliExpress

HTRC T240 Duo is a versatile 150W AC/240W DC dual-channel charger known for its 3.2-inch color touchscreen and ability to charge two different battery types simultaneously. While the hardware is highly capable, staying current with firmware is essential for both performance and safety. tps-racing.com The "Why": Why Update Your Firmware?

Updating the firmware on the HTRC T240 Duo is critical for addressing internal bugs and improving long-term reliability. Community feedback from

highlights that older versions sometimes suffer from "small annoying bugs". Key reasons to update include: Voltage Accuracy

: Some users have reported discrepancies where the charger overcharges LiPo cells (e.g., to 4.23V instead of 4.20V) or fails to save calibration settings after a restart. Firmware updates often refine these calibration protocols. Safety Patches

: High-power chargers like the T240 and its sibling, the C240, have faced recalls in the past due to overheating risks. Updates can improve "Maximum Safety" features like automatic charge current limits and temperature thresholds. Feature Support

: Updates may enhance "Smart Battery" compatibility (often requiring specialized cables for DJI batteries) and improve the Terminal Voltage Control (TVC) functionality. Integral Drones The "How": How to Update Your T240 Duo

Although the charger officially "supports firmware upgrade," finding the specific software can be tricky as it is often bundled with PC Link tools. AliExpress HTRC T240 DUO Charger | Charge your batteries!

has long been a go-to for its dual-channel 150W/240W power and intuitive 3.2-inch color touchscreen. However, as battery technology evolves, keeping your hardware current is vital. The latest HTRC T240 Duo

firmware update (v2.3.0) represents a significant leap in performance, safety, and precision. Why the New Firmware is Better If you have been on the fence about

The v2.3.0 update isn't just a minor patch; it fundamentally improves how the charger interacts with your batteries.

Massively Improved Accuracy: Users report balance charging accuracy improvements of up to 90%, with cell voltage deviation dropping from ±0.02V to a surgical ±0.003V–0.005V. This precision is critical for extending the cycle life of high-performance LiPos.

LiHV Support: The update adds full support for Lithium High Voltage (LiHV) batteries, allowing for end voltages up to 4.35V or 4.4V per cell (8.4V total for 2S).

Enhanced Safety Algorithms: New logic better detects minor voltage drifts during the balance phase, preventing "puffed" batteries caused by incorrect cell detection.

Thermal Protection: Improved thermal management now dynamically adjusts charging current based on real-time internal temperature, preventing overheating during high-amp sessions.

Stability Fixes: It resolves a known bug where the charger would occasionally freeze during long cycles, requiring a manual power cycle. How to Update Your HTRC T240 Duo

Updating your charger is a straightforward process that requires a Windows PC and a USB-C cable.

Download Resources: Obtain the latest firmware file (e.g., htrc_t240duo_v2.3.0.bin) and the HTRC Firmware Update Tool (v1.5.2 or newer) from the official HTRC download page. Connect : Plug your into your PC via a USB-C cable.
