Many BMS boards have a TX/RX header. Using a USB-to-TTL adapter and a terminal program (like PuTTY or CoolTerm), you can send the command: AT+WTY=BATINFO Or in hex: 0xA5 0x02 0x01 0xA6 The BMS will return a structured string like: +WTY:BATINFO,CHK=Li-18650,Cyc=342,SOH=87%,Temp=28C,Warr=6M The cursor blinked for a long time

Compare the Design Capacity (100%) against the Full Charge Capacity (green bar) to see how much life the battery has truly lost. 📊 Comparison with Standard Tools Using a USB-to-TTL adapter and a terminal program

WTY-BatInfo makes calculating health simple by finding the difference between your factory limit and your worn capacity. For example:

"This unit has endured 450 cycles. While the SoH remains at 88%, the thermal log shows frequent excursions above 45°C. The WTY flag is currently 'Green,' but predictive modeling suggests a transition to 'Amber' (Warranty Risk) within 60 days due to increasing internal resistance." 4.
