New guy here and am seriously considering an Olight X7 Marauder. My concern is the batteries. There have been numerous reports here and elsewhere that the Olight batteries for this light often times have insufficient power to operate Turbo S as designed. Some have recomended unprotected Samsung 30Q button tops instead. Others say the 30Q's are too short and you have to shim with magnets. If the steeply priced Olights would work properly , I think the peace of mind aspect might make them worth it. Would appreciate hearing others thoughts and experiences.
