First of all I have these batteries BatteriesI have fully charged them. Although I haven`t got the last 4 issues yet, should be any day now, I thought I would inset them in the box (its not connected to anything) and measure the voltage across the terminals as a test. Herein lies the problem as I thought it should be around 12.5v but am only getting 4.2v, is this correct or do I need to get another battery box? Nick

Check that your batterys at the + end are making full contact with the battery box terminals. When you say tested the terminals you meen the terminalsat the end of the lead. Current builds:-C57,Zero, Lamborghini Countach, Caldercraft HMS Agamemnon,Robi,R2-D2, MFH Cobra .

Have just re-inserted the batteries and retested across the battery terminals I get 12.4v which is correct but at the lead end I now get 0v, whereas last night I had around 4.2v

My battery box is doing the same - 12.6v across the battery series, 0v out on the power cable. But based on the start-up sequence that we need to perform on R2 the 1st time - I'd expect 0v out until the battery/charger circuit is initiated. If it was putting out the 12.6v already there wouldn't be a need for the start-up sequence. So I'm thinking this is normal at this stage of the build. Current Builds: R2D2, Millenium Falcon

Yes that is correct as it needs switching on first so wait until your R2 goes through the start up procedure. Current builds:-C57,Zero, Lamborghini Countach, Caldercraft HMS Agamemnon,Robi,R2-D2, MFH Cobra .
