12 Cell Brushless T2 Build Up

[James]

I fixed the tranny, but i dont know how to use this charger. Its the GWS-MC2002 i got from off shore electrics. I have a super brain 809 i got like 7 years ago, and was wondering if i could plug the 809 charger in to the wall, and plug the two car battery plugs from both chagers into each other, so the suped brain would be the 12V power supply. Is this idea completly stupid? There is als a knob on th charger that sais current adj. (%) then around the knob is 10-20-30-40-50-60-70-80-90. And a bunch of people told me to get a lipo charger, but i wouldnt trust my self with lipos till im like 18-20. I would burn down my house, or ruin them some how. Thanks for the help
