No. A BMS is not a charger. If the pack has 2.7V per cell and you connect 4.2V per cell to BMS, only the series resistance of batteries and BMS are limiting the current and most likely current exceeds safe battery charging current and hopefully the BMS overcurrent protection shuts down the charging.

Thermal runaway begins when the heat generated within a battery exceeds the amount of heat that is dissipated to its surroundings. If the cause of excessive heat creation is not remedied, the condition will worsen. Internal battery temperature will continue to rise - causing battery current to rise - creating a domino effect.
The specific meaning of the red light can vary depending on the manufacturer and model of the inverter. Generally, reasons when the inverter shows a red light include: When it is detected that the input voltage is too low, the inverter will automatically switch to the under-voltage protection state; When the input voltage is detected to be too high, the inverter will …
