Sorry meant to mention as well have to hold the on put all the time as soon as I realise the on but it switches off and when on there is a red bar next to the battery but no bars but the battery is fully charged

Error 30 is often a connection problem and sometimes a controller issue. How do you know the battery is fully charged? Voltage readings from the battery leads? Where did you buy the motor? Any warranty coverage left?
