And would I need to measure each of the 24 batteries and then average them out? How do I convert the measurement into an SOC or capacity estimate? What are all the factors I'd need to account for? E.g. Measure the SOC using a hydrometer (?) and calibrate accordingly? I believe something of this nature is possible, though I don't know exactly how. What reduced capacity would be appropriate in this case? FWIW the batteries have rarely discharged down below 60% (as shown by the BMV-700, whatever that's worth) and only twice below 50%. 330Ah, to account for the batteries' reduced capacity over 5 years of use. (B) pre-program it for a reduced capacity, e.g. I think it worked well, because the batteries still seem to function well, although I don't have any empirical measurement of this beyond "we generally have had power when we needed it". This is what I originally did with the BMV-700. (A) I could pre-program it for a capacity of 360Ah. How would you suggest going about it? A few options / questions: So I need to calibrate the battery monitor. While I try to get the warranty activated I want to use this cheap AiLi monitor to tell me the State of Charge (SOC) (and eventually replace the broken BMV-700 with a repaired one). ![]() I had a Victron BMV-700 battery monitor that has worked well for the past 4 years and 11 months but recently broke. The setup is a 17280w battery bank (24 lead-acid units of 2V each, rated at 360Ah at C5, in series for a total of 48V) that is charged by solar panels via a Victron SmartSolar MPPT 150/70, and supplies AC current via a Victron Multiplus 48 / 3000 / 35-16 Inverter. I'm not sure how to go about it given the age of the batteries and the fact that I am not currently able to charge them to 100%. In some cases, the nature of the item means that it is non-returnable, for example, due to hygiene/health and personal care/wellness/consumable nature of the product.I am looking to calibrate a new battery monitor for an off-grid battery bank that's ~5 years old, since the previous battery monitor stopped working recently.
