Are your tabs located 2-3mm up from edge ?? Or are they level? 170 amps average with a m447 is high. How is your stinger set ?

well thought i would show what i have been up to.
we had a great race facility up here on the coast, a onroad race track that could take up to 1/5 scale cars and a offroad 1/8 scale track.
a lot of people and the club put in around $50,00 towards it and the council dropped in around $250,000.
it lasted 12 months and some fat hag complained and it was shut down
that was 3 years ago and why i got back into boats.
about 6 months ago a hobby shop put in a small indoor track,its very tigh and technical but lots of fun,hopfully he will get the place next door soon and thats 4 times the size.
any way here is a video of the crashing oops mean racing

here is the hull i bought off you mate. i copied bits and pieces from yourself and andy and come up with this. ran it yesterday with a m 447 and puffed the lipo (tp 30c 5000 mah) averaging 170 amps, i think cause last couple of runs in my rigger , a bit of moisture got into the batt. but new tp 45c battery on it's way, and away we go. boat ran good and i'm jibberin s#it cause i just got back from the raffels with a skinfull, but just want to say thanks to paddy and andy for your help and i can't wait to race this boatSeveral boats in various stages of destructionComment

I am surprised. I have a 45c 4s TP and it is my best battery. Mind you my boats only run a few second and then rest so I guess that helps. I have puffed Elite, Zippy and Flight Power but always by running longer than I should.Several boats in various stages of destructionComment

yep, got 3 laps in and had to row out and get it. prob not even 1 min run time. the end of the battery where leads come out was puffed a little, and you can see where solder bled maybe from balancing taps. when it cooled down, it went back to shape and looks ok now, but i don't think i will trust itComment

If you have bled the solder and run 170A average then I would wager that you have rooted the pack.
I have 1 setup that will pull amps like that and spike well above and it has rooted packs too.
Bottom line is: do not setup to pull major amps unless you like replacing components often.
On that note, amps is not always the killer but total watts can be a shagger of bits too.
I have just made a 9xl into a paper weight by feeding it with too many watts. I was good for amps but the watts to the motor did the damage, prolonged overheating = demagnetise.
A demaged motor will root an ESC too !!See it....find the photos.....sketch it it....build it........with woodComment

A 30C@5000mAh will provide 150A sustained for a while.
