I Own 10 Zippy/FlightMax packs and ultimately decided to pull the heat shrink off and inspecting all solder joints and wrapping the cells together with nylon packing tape and re-heat shrinking them. This may have not ben nessasry but I surely feel better inspecting them prior to use. It's a little work and a small investment for peice of mind but the end result has ben being able to save nearly a thousand dollars .
My only real complaint is that 3 of my packs (2-4s and 1-5s) and several of my friends whom also have over dozen packs collectively have had issues with the balance plugs being faulty. I bought replacement plugs with wires from MaxCramps and soldered them on and now they work and balance near perfection.
This isn't really a complaint because I enjoy soldering so much so replaceing the wire is not a problem, but why do they use 12G with some of the Flightmax 4s 30C packs I bought and one of my buddys who has 3s Turnigy packs have 8G wire.
WTF is up with that ?
