When HV lipos first came out, I recommended them, because they deliver longer flights and more amps with less votlage sag. However I later retracted that recommendation, because I heard too many reports that they puffed and died after only 20 or 30 flights.
Has anything changed in 2018?
Now I have a fancy battery test rig that lets me run these packs through 40 or 50 cycles to find out!
