Here’s a helpful post for anyone looking to update the firmware on their HTRC T240 Duo charger.
Should you update?
✅ Yes – if your T240 Duo consistently mismeasures voltage by >0.05V.
❌ No – if it works fine. New firmware rarely adds features; it only fixes factory calibration drift.
Warning: HTRC does not offer a recovery tool. If the update fails, your charger becomes a paperweight. When in doubt, leave the firmware alone and manually calibrate using the hidden menu (accessible via code

Once upon a time in the buzzing world of RC racing, a pilot named Leo relied on his HTRC T240 Duo
to keep his drones in the air. For months, the charger was his reliable sidekick, but as new battery tech emerged, he noticed it struggling to keep up with the precision he needed. That was until he discovered the "BETTER" way to charge: the HTRC T240 Duo v2.3.0 firmware update. The Turning Point
Leo’s old firmware (v1.2.1) was good, but it wasn't perfect. He faced occasional USB disconnections and a balance error of about ±0.02Vplus or minus 0.02 cap V
per cell. In the high-stakes world of racing, that tiny variance meant lost power on the final lap. The Upgrade Process
Driven by the promise of better performance, Leo followed the simple path to a "Better" charger:
Preparation: He grabbed a micro-SD card, formatted it to FAT32, and downloaded the latest .bin file from the Official HTRC Support Portal.
The Handshake: He inserted the card into the slot beside the USB-C port.
The Transformation: Holding the power button for seven seconds, he watched the screen flash from blue to red, signaling the update was underway. A "Better" Reality
When the charger rebooted, Leo didn't just see a new version number; he saw a superior machine. The transformation was immediate: Insane Accuracy: His balance error plummeted from 0.028V0.028 cap V to a nearly perfect 0.004V0.004 cap V —a 90% improvement.
New Horizons: The charger now fully supported LiHV (High Voltage) batteries, allowing him to push his gear to 4.35V4.35 cap V per cell safely.
Solid Reliability: The frequent freezes and USB drops were gone, replaced by rock-solid stability that lasted through his longest charging sessions.
Cooler Performance: New thermal control algorithms adjusted the current dynamically, keeping the unit from overheating even at a full 10A10 cap A
Leo realized that "Better" wasn't just a marketing buzzword—it was the result of a few minutes of maintenance that extended his battery life and gave him the competitive edge he’d been missing. htrc t240 duo firmware update - AliExpress
