I have a problem with a 48v battery used on an off-grid power system - one 2v cell has failed. The battery has actually only been cycled 12 times and the other cells seem ok so it stings a bit to replace a £7000 battery, that has been worked fairly lightly. I know best practice would be to replace all cells, but I am going to try swapping out the dead cell. Unfortunately there is a 16 week delivery time for the replacement cell. I would be interested to know if I could temporarily run as a 46v system to preserve the integrity of the remaining cells until my replacement cell is available. My battery pack is 700ahr 24 x 2v gel cells. I have a Victron Quattro 48v/10000/140 inverter - can the settings be adjusted to compensate for the missing cell and if so can anyone help me out with some suggested settings please? I purchased my off-grid system as a pre-wired package, so I don’t the experience of assembling it and setting the initial parameters.
I hope you can help!
