I guess they're the "Pre-LiPo" stage for people maybe...they claim to not catch fire etc. but if you just follow directions when charging a LiPo, you'll be fine.
my first nimh saddle packs caught fire and melted a bunch of stuff on my counter including a servo and axle housing, never had a lipo catch fire and I've been extremely hard on them.
The one thing that does sort of catch my eye is the increased cycle count, which is nice and might make it worth it even with the higher price tag. Although, with all things, the price will go down a bit after the new wears off. We'll see what happens in the next bit.
