Hard to say if you got a out of spec pack, I kind of remember Danny not selling that batch as race spec and that's where the out of spec pack sale started from which I don't see on the left side of smc's site any longer. From memory I got one of if not the first 7200's out the door, received on Friday raced on Saturday and reported back on Saturday. What i remember from my back & forth with Danny on Monday is that he was not going to be shipping those packs out till he got mine to test which I mailed back that day. No puffing, nothing visually wrong, just weak performance.
This is going a ways back though so can't say for sure.

I have a brand new 6500 70c 2s and I tried to balance charge it and it wouldn't peak out . It was on charge for 2 hours and just kept bouncing the one cell between 4.19 and 4.20 .

I have the same lipo smc 6500 70c got it last month and it does the same thing as yours?

What charger are you using?

Love my SMC packs!

That is all

Dittos here!
I will be rotating out some older packs and replacing them with SMC only!

I used the square packs on sat, amazing. Thanks Danny.

Got a new charger al is good , was using a Hitech x1 . I have a 10 anp dynamite now .

i also ran the square sat charging at 12 amps no issues ran great lots of punch even with a 10.5 also ran the 7.5 smc motor in a t4 with the 50c 5000 pack had to lower timing to make truck driveable lots of power thanks for the great products and price.

Anyone own both? Looking for my sc10. Currently running gens ace. Quite a diff in price between 70 and 80c smc's. Wondering if the additional 10C is worth it.

Well I'm getting out of 1/8 scale so selling off my Race Formula 4s 6500mah. Got it mid July last year and it looks like (wne back to my results) I only used this for 4 race days so less than 20 cycles on it. Not in stock currently at SMC: http://www.rctech.net/forum/r-c-item...-hardcase.html

if your deal falls through; PM me please.

It really depends on what type of racing you are doing. If you are racing a competetive blinky class where every tenth counts and you need that little bit of extra edge then yes with the low IR that this pack has you may get a benefit from it.

wigman,

thanks for the reply. I run 7.5 mod so it looks like the 70C will be plenty. I run smc 4600 shorties on my b5m and they are great.

I run the Tekin RSX and gen 2 7.5. What kind of run times are you getting out of this pack? I will be running 10 min mains and am not sure if it will be strong enough.
