Anyone use ProTeK li-po batteries
 

I am looking at the 5s 4K 20c batts. to use w/ a 1515 Neu and mmm esc. Has anyone had good/bad luck w/ them.

Hit the search feature, plenty of threads about this. Not sure if there were any real results or graphs. My $.02 is just to stick with enerland based packs. Best I have tried...
