i have a lumapower sidekick mrv ultra. i use the m-65 battery ext on it for use of 2 18650 batts. iv'e noticed they came out with the m-35 battery ext for 3 c123 batteries. other than a slightly shorter tube length, is there any benefit of running 3 c123's vs 2 18650's? iv'e searched and cant find the info im looking for. thanks
