I have contacted SOK directly and they have been helpful but I was looking for a second opinion on this. I have two 100Ah batteries wired in parallel for a total 12V system with 200 Ah capacity in my campervan. They run a number of different things and they charge in a number of different ways. The performance I am particularly concerned about is when charging the batteries. One of the two batteries has a single cell that jumps to a higher voltage than the rest and the battery enters charge protect mode.
The picture is from some home automation system I have that is able to plot the cell voltages over time. Eventually what happens is that the cell drops and the protections turns off, then that cell jumps up again. As this is a campervan system the batteries have not been on a prolonged charging stint and typically only charge while I am driving. I have noticed this behaviour since getting a solar panel and the battery is being charged while already at a high voltage.
Is this behaviour normal/concerning any recommendations?
SOK themselves said it was relatively normal and to put the battery on a prolonged charge.
