I got two flights on a MA 4s1550 before it puffed, bought a FP evo20 4s 1500 the same day to compare. The MA has been dead for over a year and the FP evo is still fine. At this point I dont care if they do hold voltage at rated amps if they dont last they aren't worth the few bucks saved.

If you guys ever come across DN Power packs avoid those also, buddy bought two, one puffed after the first flight the other puffed in storage with less then 10 flights on it.

We have both decided that it isn't worth the few bucks saved on these so called bargain brands.
