Those are interesting, I always figured integy as a knock off artist. However, i don't trust the material to last

you don't trust the stock or the integy material to last?

integy FTL!!! The only thing they have that lasts are the allen drivers I have two sets and swear by them.

Id wait for someone else to buy integy. to date i have had bad results with anything (except the hex drivers) integy. the stock shafts from traxxas are very good actually especially if you have your slipper set up properly.

I have an update on the puffed lipo. After I let it balance itself I charged it and it appears to be ok. The swelling went down pretty quick and it took a full charge. I talked to maxamps today about the issue and got some good feedback. They said if I can't get this one to come back they would give me a discount on some new packs. I'm happy with the offer, however I think the pack will be ok and unless the discount is steep I'll prolly pass. I just got done running the truck. I did 10 minutes of hard running and took batt temps. 107 degrees. Did another 10 minutes and hit 118 degrees. I'm running the stock gearing of 18/65. The motor was very similar temps to the batts. I did change the voltage cutoff from the autolipo to custom of 12.5. Maxamps was saying that the auto will let them go down to far, which may be what happened.

On another note I made some changes to the truck. I changed to firmer springs front and rear. I opted for the highest ride height. I changed out the 40wt oil for 50wt. I dropped the center roll to the lower position. With the offset wheels +.5" prolines it now handles really well and does not have body roll and stays on its wheels much better. I pulled the stock slider shafts and dropped in the traxxas cvd's. This thing is so much fun, I still cant believe how much power this thing has and that it can handle it. I'll post some pics soon.

If a pack puffs, its done for usually- it'll puff each time you use it in the same application given the same stress/load.

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).

Same here, I don't leave home without mine

Integy, the only thing i have of theirs is their drivers. heard enough horror stories about their parts to steer clear for a long time. They had a copy of the type 3 (I think, but no longer produced) UE suspension, that a friend (coolhand_country here) had and swore by

i trust integy products that are not "there alloy" so like a steel roll cage i would trust or them hex drivers

My luck hasn't been great with the integy hex drivers. Most are OK, but I got into an argument with the LHS guy saying that a screw wasn't 1.5mm because my driver didn't even come close to fitting. He broke out a MIP machined 1.5mm driver and it worked like a charm. Sadly, I think I'll be replacing the integy set over time. YMMV

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.

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.

[suicideneil]

8.4amps x 35c = 294amps. I would seriously hope they dont puff given those specs . "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.

[suicideneil]

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.
