Balancing starts within 0.03V/cell.
Final voltage is 4.20V ±0.01V (or 4.35V for LiHV).

Finding the Right Update

Manufacturer's Website: The best place to find firmware updates is on the official HTC website or through their support pages.
Device-Specific Forums: Online forums or communities dedicated to HTC devices might have threads about updates, including links to download them and guides on how to install.

Connect the charger to AC power or a stable 12V DC supply.
Do not start the update with a low-input voltage (risk of bricking).

Upgrade advice

: 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 htrc t240 duo firmware update better new

3.1 Critical Bug Fixes in Newer Firmware

Channel cross-talk: Old V1.03 had a bug where discharging on channel A affected voltage readings on channel B. Fixed in V1.08+.
Fan control logic: Early firmware kept fans running at low speed constantly; newer versions only activate fans above 45°C, reducing noise.
Input voltage calibration: Improved DC input tolerance (11–18V), preventing premature low-voltage warnings when using a 12V lead-acid battery under load.
