Any Failures on Li Fe Po4 cells?

I know two MMM who die with A123, look here:

My MMM die on 6s2p A123 with a Neu 1515/2D (3day ago)
The other one was on 6s2p A123 too.

This is the battery who are recommended by Castle...

keep in mind the % of people using them vs lipo is very important when assessing whether they are safer to the controller. if anything id say they have the potential to do MORE damage (a 6s2p pack weighs a TON and can supply a huge amount of power...)
my 5 cents :)

I agree with you, but it's always the same thing,

I am running 5s2p A123 on a MM without issues, MM who are rated for 3s lipo....
(5s2p A123 is ~800g)

So imo the probleme isn't A123 but MMM

yeah of course - bad design! im sad i sold my mamba.. o well at least my MMM is working and im very happy with it!

ok thanks chaps i must have missed that one. i got some dewalts heading my way and will just try my luck. strange ,i would have associated "luck" with nitro's as opposed to electrics.
