Seems to be one thing after another with this bloody system ive bought! Im not having issues with my pump, well I say its the pump im not entirely sure. When I turn the pump on I can get just about 15 mins worth of work from it before it cuts out. I thought maybe the battery was a little low so I left it on for a few hours to charge and went out again this morning and the same thing happened - 15 mins work and it cut out. Now after another 10mins or so itl come back on again but not for long. I tried plugging in the charger and letting it run to see if it cut out again which it did so im assuming the battery isnt the problem because surely it shouldnt be cutting out if its plugged into an electricity supply? Anyone else had a similar issue?
