I bought a 7.4v Lipo battery (not from RobotShop but it looks like your item RB-Dfr-160. It was out of stock here.) and it arrived showing zero volts. Is this to be expected? I have not tried charging it yet as the charger (which was ordered from RobotShop, RB-Dfr-607) has not arrived as yet. There do not seem to be any switches to flip. Thinking that perhaps one of the wires had come loose I measured the resistance across the connector and found 24 Ohms. Lithium batteries being what they are, I do not want to tamper with the orange plastic wrapping.
Would that charger be able to do anything with this battery?
