“I've got two of these now, one each on the input and output of the aux battery in the car with the aim to monitor to State-of-charge that way. They are working ok for short times (minutes to hours) but regularly 'freeze' when left running for days, which is the whole purpose in this case. Not sure what the issue is, just a quick disconnect and reconnect fixes the problem but obviously all accumulated data is lost then, and already once they freeze anyway.”
