I finally started playing minecraft again after taking a few months off and when I went to charge my drill, it was still only doing 32 eu a second, which I had previously reported. I downloaded the latest release of GT6 and it started charging much faster at first, then it just stopped. I picked up the battery box and made sure that the transformer next to it had its light on, put it back down, and still, tools will not charge. I attached the battery box to a different transformer and still no dice. I threw in an LV lead acid battery and that started charging fine, so I took it out and put the drill back in, and it started charging again but stopped again after a few seconds. Each time I switch the tool out for a battery it gets it going again but always stops after charging the tool for about 5 seconds.
Actually, the longer I let the battery charge, the longer the tool will charge when I switch them.
