the supercharged mod allows 4 stack of charged with light and 1 mod to get charges + 1 to use it takes 3 armor piece with stacks on stacks its 4 + exotic there's basically no need for the weaker version or to use both, i only ever used taking charge and high energy fire or something else, which takes only 2 armor piece. If i wanted i could use 2 of the weaker version and put on for example enhanced impact induction to get grenade energy on melee hits and use like double heavy ammo reserves. In my opinion 2 of the weaker is 4 energy total while this one is 5 energy total. there's no point in having 5 stacks since usually 2 can be used and 4 is more than enough. bungie please change it so we can reach the max amount of stacks (5) instead of 4 stacks otherwise just 1 or 2 of the weaker one is enough and it just feels overpriced and changing it it would be 1 point cheaper than 3 of the cheaper version (6 enrgy).
