I just like the convienence of not having to lug around a brick with me also no hookup wires to fuss with.

A hot lipo can probably out perform a gel cell in supplying large amounts of current in a very short time span. Probably live to do 'dozens' of launches too.

One thing did concern me was dropping in what amounts to a dead short (the first few microseconds) onto a Lipo. I have seen the results of shorting out a lipo albeit a lot longer than microseconds. They will go off like a road flare!

Speaking of lipo safety I might see if I cant get some of that foamy tape over the battery springs just so they wont puncture one by accident. Punctures... see above sentence

Oh one last thing I will probably look into the JST connector and its conductors as to their ampacity. A mod may be in order
