Report: Firmware Update for the HTRC T240 Duo – Benefits and Procedures
Post-Update Checklist: Verifying the "Better New" Experience
After your htrc t240 duo firmware update, perform these three tests to ensure the "better new" claims hold up for your unit:
- The Fan Test: Start a 1.5A charge. Stand next to the charger. If the fan is off for the first 2 minutes, the update worked.
- The Sync Test: Connect a half-empty 3S 1500mAh to Channel A and a 4S 2200mAh to Channel B. Press "Start" on both. Watch the clock—they should finish nearly together.
- The Storage Test: Put a fully charged LiPo into Storage Mode (3.85V). Old firmware might take 40 minutes; new firmware should take ~18 minutes.
Introduction
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. htrc t240 duo firmware update better new

Breathing New Life into a Workhorse: The HTRC T240 DUO Firmware Update
For years, the HTRC T240 DUO has been a staple on the workbenches of RC enthusiasts, drone racers, and battery technicians. Its ability to charge two different types of batteries (LiPo, LiHV, LiFe, NiMH, Pb) simultaneously at up to 240W made it a reliable, if slightly no-frills, workhorse. The Fan Test: Start a 1
However, like many pieces of intelligent hardware, the T240 DUO’s soul is its firmware. And for a while, that soul was a bit dated. Recently, HTRC rolled out a significant firmware update (version 2.1 or later, depending on your production batch). This isn’t a security patch—it’s a functional overhaul that changes how you interact with the device.
🔥 Why You NEED the New Firmware (Better Features)
The stock factory firmware is functional, but the latest updates (post-2023) fix critical issues:
- LiHV Charging Fix: Older versions undercharged LiHV batteries (4.30V vs. 4.35V). New firmware delivers the correct 4.35V/cell.
- Internal Resistance Accuracy: The old firmware often showed wildly inaccurate IR readings (±10mΩ). The update recalibrates the algorithm for readings that actually match a standalone IR meter.
- Fan Noise Reduction: The stock firmware runs fans at 100% constantly. The new update introduces temperature-controlled PWM fans—silent at low loads.
- Channel Sync Bug Fix: Fixed a glitch where Channel B would stop logging data if Channel A finished charging first.
Verdict: If you charge LiHV packs or care about IR values, the update isn't optional—it’s essential.
