@ExFirefighter42 Worth noting that the 70A non-isolated is quite a beast compared to your 30A isolated - it's shifting a fair chunk of current so the thermal management works harder.
@MPPT_Wizard @CamperCarl good points all round. One thing worth adding — your SmartShunt's tail current setting is just as critical as the charged voltage threshold.
@CoveChris I ran almost exactly this combo for a while and honestly the Orion does such a thorough job of isolated, properly regulated charging that the split-charge relay starts to feel redundant...
@Gibbo39 I've been down this exact rabbit hole with a secondhand pack. One thing nobody's mentioned yet — before you do anything else, check the internal resistance of each cell individually if...

@PanelRuss Classic Daly behaviour, I'm afraid. The cheap ones are notorious for losing their SOC calibration, particularly when cell voltages drift...
