As suggested - here we are Gents & Ladies! If anyone thinks they have an issue with a SmartGauge it's important to us. I am sorry it has taken us so long to catch up. The SmartGauge is an absolutely fantastic product so we clearly need to address your concerns. If anyone has a unit that they believe has this problem then please call us to arrange its return. If we conclude there is a problem then we will replace it immediately free of charge. I will say that we have conducted reviews on a couple of the small number of units returned to us and found there to be no issue however we also don't doubt the experience of many customers on this forum. You know your electrics far better than us. In addition to replacing any units found to be faulty, we will also offer an "at cost" upgrade to our DataCell I or DataCell II battery monitors if you are interested. The DataCell I will monitor multiple battery banks for voltage and SoC. The DataCell II will also monitor SoH (State of Health) as well as other parameters too...
