So I went to plug in my batteries to my Summit, I went to connect the non bec side first as usual, it would always spark if I connected the bec side first. So I plug in the battery and all the sudden it sparked started smoking and the connector came off the battery I'm not sure what happened, everything worked just fine the other day. Guess this is my kick in the pants to get a Hobbywing Quickrun WP-860 and Castle BEC.
