hi all, i've try the dual japod batt mod (will post pic latr now i'm charging them.) one thought is that to me the mugen cover is quite big unnecessarily, so i'm thinking about modding our stock batt. cover to allow dual batt. mod, the idea is that we apply acetone (which can dissolve most plastic) to the cover in a smart way so that it only extrude where the extra battery is. what do you guys think about this??
