Posted December 19, 20195 yr My Pylontech batteries and the Victron BMV 702 battery monitor can not agree what the correct SOC is in the morning. The BMV value is usually +- 15% higher than the Pylontech's. During charging the BMV also reaches 100% SOC long before the Pylontechs. I have set the charge efficiency and Peukert's exponent in line with the recommendation from Victron to 99% and 1.05. The battery capacity has also been set to the right value. Has anybody figured out which charge efficiency and Peukert's exponent values give the best alignment between the BMV and the Pylontech SOC calculation?
