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.
Beyond the safety risks of overcharging, other issues included frequent system freezes, unresponsive touch screens, and errors when switching between charge modes. Many owners grew frustrated with a critical problem: even after calibrating the voltage with a precise multimeter, the charger's internal monitor would display the correct information but then completely ignore it during charging.
Before starting, verify if you actually need an update. Navigate to the section in the charger's main menu. If your version is or older (often released around 2021), an update to
