I have 2x SmartLithium 12V/150Ah batteries, as a series 24V pair, located right next to each other.
Battery A claims its temperature is 8°C, with a 2°C offset (i.e. with no offset, 6°C)
Battery B claims its temperature is 6°C , with a 1°C offset (i.e. with no offset, 5°C )
The BMV temperature sensor connected to Battery A positive terminal reads 7°C.
Dedpending on who is correct, these temperatures are close to the "do not charge" threshold of 5°C.
Which should I believe?
