I've got a SmartShunt 500 installed in a system with 2x Relion RB100 in parallel. Out of nowhere, the SOC will shoot back up to 100%, and I cannot figure out why. This happens basically every time the batteries discharge. Until I realized this was happening, it lead to me allowing them to get to damagingly low voltages numerous times since I would just quickly check the SOC on my phone and not look any further, not realizing the voltage was lower than it should be. Any ideas on what is causing this?
