Well I have a G3 I would like to make rechargable I found myself using my E2D the other night when I was cleaning my car wich I can mostly do t night as I get home during twilight. The E2D worked great but it is my edc and I use it freguently so the batteries were not full. My U2 is also great for this but still isnt rechargable. So that leaves me to my G3 works great but eats the batteries. Were can I get it and what do I need to make the G3 rechargable with the P90, also I just put an order in for the BOG Q5 drop in can that be used with the same rechargable configuration as the P90, and how does the BOG Q5 compare to the P91 in terms of output? Sorry for all the questions and long post I am new to this. Greg
