I try to maintain three 5” BF quads(FPVCYCLE GLIDE frame) for proximity freestyle(within 500metres) & two 7” iNAV quads(Iflight Chimera 7” frame) for so called LR, Max 5Km. or so. I use the CRSF full Module TX with an External 3s Lipo Battery whenever I push it to 1 or 2 Watts of output power. I fly alone all the time because no one is into FPV in my state.

I have ordered the HappyModel ES24TX Pro Micro ExpressLRS 2.4GHz ELRS Module. At 1W Output Power, Shall it fry the electronics of the Radiomaster TX16s or the QX7 Radio apart from sucking the battery,  since it does not have an External Power Source. I guess it is all right to blast 1W of output power from this module, without External Power, but just wanted to make sure from you guys. Surely. I don’t wanna fry my Radio.

Would anyone help.

Cheers !

You won't fry anything. You will just get really short life from your TX16S batteries if you run the module at 1W. ExpressLRS 2.x.x now supports dynamic power switching so I suggest you enable that option, then your ExpressLRS module will start on the lowest power setting and only bump up the power to the next higher level if the signal quality starts to degrade. Likewise, as the signal quality gets better again it will bump the power level down to the next lower power level. So it will dynamically switch power as needed.
