yes - i used to have the integy - i would strip out screws and always thought it was the screw until i broke down and paid for the mip set. boy is it every different - talk about precision machining. the real test are the grub screws - never strip.

newer maxamps are much better

As for the nice offer of a discount- if they werent junk lipos to start with, they would never have puffed; they should replace like for like, not offer a discount on new ones.

Auto lipo isnt to blame- you should be able to discharge them down to ~2.5-2.7v without damaging them- auto lipo is 3.0v per cell; trouble with maxcrap lipos is that they just dont like outputting so much current so will over heat and puff, long before lvc is hit (otherwise it would have kicked in to stop tyhem from overdischarging to too low of a voltage).

Neil totally agree on the 6000 and 8000 ma 20c packs. i have puffed a number and wont buy them again.
That said i now have a pair of 8400 35C packs from Maxamps. these are much much better. never puff in the erevo or emaxx. Even Mike will agree these are much better packs. i got them from maxamps when i puffed my 8000 they sent me these as they are too pricey to purchase at this point.

8.4amps x 35c = 294amps. I would seriously hope they dont puff given those specs :smile:. "Pricey" you say? I dont think that will ever change unfortunately though ¬_¬

well its two issues we are discussing
1) at one point maxamps packs just werent up to an erevo class truck-
i would argue they are now.
2) cost is a huge issue - i wouldnt have bought these packs - they provided as replacements - somethng you wont get from a zippy or most vendors.
3) As a side i now have 2 SMC 9000 28C packs from SPC. I love these packs they are a great price performer.

1) Time will tell I guess- looking forward to your findings.
2) Given the difference in cost and sell prices, maxamps could probably afford to swallow that loss, to keep customers happy more often. I doubt Zippy would replace a bad pack with a better one, but thats probably because the maxamps packs were being replaced anyway with the better ones; the number of times they have only offered people a discount on new packs to replace bad ones cant be ignored, but its good that you got a free upgrade for sure.

Update: Well the maxamps packs are very near the end of their life. Power is significantly reduced and not much fun any more. I spent the better part of a week going back and fourth on "name brand reliability" and "significantly lower cost". I was looking at the Hyperions and Thunder powers vs. Zippy or Rhino. I couldn't stomach the idea of spending $100 or so on the cheaper packs and being let down so I went for the Thunder power pro power 30C packs. I got 3S 5000mah x 2. That set me back $259. I got my first run in today............holy crap this is one bad mofo! Didn't take long to end the session as I caught my front step and took out a lower control arm:oops:

The pack size is perfect for the trays on the BL revo. Its cold here, 30's, and the packs after 10 minutes were a mere 75 degrees. I'm running a stock truck. Hope to pick up some new arms in the morning and get some more in. Any good suggestions for a power supply for feeding the chargers, my marine battery has took a crap and these big pack suck my spare lawn mower battery dry quick. Also may be looking to get the Hyperion Duo, I assume it comes highly recommended?
