Been running my naut mini on standard battery for 2 weeks. Was running ok most of the time. Finally got a vv battery first time ever used one. I haven't gone over 4 v I'm getting no flavour. Flooding gurgling and spitting Took coil out was liquid underneath it dried it all out tried again no flavour. Now gurgling again. I thought vv would make the tank work better. What's going on ? Anyone help ?
