So I finished my R2 before Christmas but had to wait till now to get the batteries. I bought the pink Samsung button top unprotected batteries. I’ve charged them as per the instructions , fitted them in , plugged the mains in for a few seconds and switched off then switched him on for the first time........nothing.... not a light...a movement...a sound.........I’ve checked the connections in the battery box , they look good , checked all connectors and pins...all good but still completely dead......Anyone else experienced this..... any suggestions would be appreciated.....

I’m going to go and grab a voltmeter in a while....... I will post my findings......

have you pressed the bottom button on the front of the unit.

Read elsewhere on the forums that some batteries are not making good contact in the box at the positive terminal. Some because of an issue with the box, some because the button tops are not full button tops, but just stubby tops.

I made that mistake the first time when thinking mine didn't work, just pressed the main power switch on his "bottom"

Yes......I’ve put the meter across the black and red power wire connector and I’m getting zero volts......

When I put the volt meter inside the battery box and measure on the terminals where the batteries touch I’m getting readings of 4.14v on the first 2 batteries, 4.14v on the middle 2 batteries and 4.14v on the final 2 batteries. Therefore there’s power inside the battery box directly on the terminals but there’s zero volts at the end of the wire which connects into R2’s mcu.

I think you may have a dodgy battery box please contacy C/S for a replacement. You can find the number for C/S on inside of the first page of the instruction book.
