Would these be ok in my GRUS or shall I still to Molicells?
A simple answer is NO. 5,000mah 21700s will have a max Amp rating of 15 Amps (45 Watts maximum) which isn't enough for any of the dual coil RTAs or larger stock coil tanks you own.
Stick to known brand batteries - anything you haven't heard of is probably a re-wrap and the cells under that wrap could be anything. If Fogstar don't stock that battery be sure to ask on here first - and never forget that the higher the capacity a battery it has, the lower the amp rating. For safety you need to prioritise the Amp rating over capacity. If a battery has low capacity but high amps it will need a recharge more frequently but it will be safe. A high capacity battery with a low Amp rating will go bang if you push it too hard.
