Last month, we've released the Lynx Smart BMS (NG) v1.14, introducing various improvements and bug fixes, including updates specific to the NG series.

Key Fixes & Improvements

• More accurate State of Charge readings and improved the synchronisation (jump to 100% SoC) between the battery monitor and charger control.
• Updated Voltage Settings:
  • Default charged voltages are now 13.9V / 27.8V / 41.7V / 55.6V. Devices using the old 14.0V setting were updated automatically, which will help the State of Charge sync to 100%.
  • Float voltage levels are now 13.5V/ 27.0V/ 40.5V/ 54.0V (depending on system configuration), aligned with the values in the manual.  
• Fixed the alarm relay that did not activate on high temperature alarms.
• Smoother transition to float stage when used with Multi/Quattro, allowing the system more time to stabilise at the float voltage.

NG Series Improvements:

• Fixed repeated absorption timer (default is once every 30 days)
• Added cell-ID information for minimum and maximum cell voltages and temperatures, now visible in VRM /requires the latest GX beta firmware).
• Added a data loop test to validate the communication interface:
  • When a loop cable is connected between the battery BMS connectors, the BMS will close the contactor, but charging and discharging remain disabled for safety.
  • The contactor will not close if the interface is not working. This test runs automatically.
