BMS over voltage warning

Hi,

For the past 3 nights whilst charging my battery in the cheap overnight octopus go window, I have received 3 BMS over voltage warnings.

When looking through the logs for the times that these occurred, it's when the battery is approaching 100%.

However when looking at the battery voltages, the warnings occur around the top end of 55v and low 56v.

Is this something I should be concerned about?

I appreciate that the software is there to protect the battery but I'm finding it particularly annoying that the battery voltages have hit those numbers before and the warning hasn't triggered and now it is triggering.

If anyone can shed any light on this that would be greatly appreciated.

Qyaunos1 I got one this morning too when my battery hit 100% and 56.49v, Not sure if it's an issue but will keep an eye on it.

I'm aware that temperatures can affect voltages so not sure if it's something to do with the temperature.

One thing I have since noticed however is that at a lower SOC the voltages have been higher so not sure why it's triggering at a lower voltage but higher soc
