anybody parallel charge? that's the way to charge!
I have a Hyperion super duo 3 and run it on an 1100 watt power supply
with charge rate at 20 amps per port!
I can do 4 or 8 4s or 2s batteries at the same time it takes to charge one!

I know plenty of racers that show up with packs charged and ready to go. I don't think that's it, its not as healthy for the pack as charging once you show up but your pack is not going to split the case from that.
If promatch gave an upgrade pack at no charge they rock so who cares what did it in that case but just saying I can't see how that is the issue.
As long as you're charging a quality pack with a good charger at 2c, there's no damage being done to the pack. If your charging $500 worth of lipos with a $50 charger... stick to a 1c charge rate. I have never had a pack split like that and I have charged at 2c or more for a few years (2c unless I'm in a rush then 20a on smc pack)
I have a reedy 6500 pack that's past 2 years charged @ 2c now with no issues.
I never charge the night before, always left at storage voltage, always balance charge. That's another thing, balance charge on a good charger does not delay the charge like it does on a cheap charger. I go from storage to peak in 5 min or less and 7v to peak in 15 min at the most balanced.
I run 2 to 3 classes with a single powerlab6 using 2 SCT packs and one pack per buggy for the night.

rebuilding my truck after a full season on it. turns out my rear shock tower is slightly bent. I have some cf tekno towers sitting here and I don't know what I should do, straighten the stock tower or throw the cf ones on. My fear is that if I can bend a stock tower, a similar hit would just snap the cf tower.

from indoor clay med traction to loose outdoor with bigger jumps
how much do u change your ride height front and rear

I never knew that I shouldn't charge packs more than an hour or two before using. I seldom had any problems with bigger packs, most of my 4s packs never puff. Most of the problems are with 2s packs that're over 5000mah. I'm going to use the 2 new Promatch 2s packs very carefully and keep a log on how I take care of them. I have a bunch of smaller packs, Gen Ace 2s 50c 5000mah that're around 2 years old that're still going like champs, no problems at all. Must be the difference in cell size between a 5000 and a 7200mah pack.
At home I use a Hyperion 720i charger, at the track I use a iCharger 208b with a 600 watt power supply. I never charge my packs higher than the suggest c rating most of the I charge at around 10amps. My Gen Ace packs are rated at 5c, I've never been in such a big rush to charge that high. The person I delt with at Promatch said their packs can be safely charged at 20amp, I normally charge them at 10amp to be safe.
If your bringing 20 packs I'm guessing you don't really charge at all even for 3 classes? If you are charging at the track, think about taking the good charger to charge your packs with.
That's like having a Porsche that you leave in the garage and take the pinto out whenever you go for a drive up the coast.

Fq06; What power supply are you using with your charger

2mm front and rear change doesnt sound like much but thats what I was doing

Nothing special, Hobbyking 30a 540w 18v PS. That's the dumb end of the system, it just needs to put out what you need for your charging expectations and running all 2c packs the powerlab doesn't need a nuclear power plant feeding it 
Computer PS's work well too for super cheap but my PS was cheap enough and a little cleaner and more convenient on the pit table.

I dont exactly remember what my ride height was at indoor on a slick track but it was a little to low though i think i noticed there was ingraves underneth the arms. The softer springs/oils i was using accounted for that also.
When i ran at a event for 3 days there was big jumps/big track but really rough and dry i had the ride height at 27mm all around .

What's wrong with 5000mah batts in a tekno? I'm rocking 5000mah smc in my truck and never have a problem.
Guess I should feel lucky, I charge at 10 amps, pull them off the truck right after racing and start charging after marshalling. I also charge the day before in most cases, and I've never had a smc swell. Granted there is a good bit room in the cases, they still have the same amount of squeeze to the case.
I also have the carbon front tower and it can take a heck of a beating.

I have ran nothing but gens ace 2s 500mah 40c and 50c batteries with no issues. They barely get warm. Using pro4 4600 with a 14t pinion. This truck is heavy but efficient.

I've noticed a few guys running their pistons upside down. What does it change? Sorry for the noob question

Also, there's a lot more room in the case with 5k cells compared to 7k+ so your 5k may actually be swelling more but its not pressing the case.
I seem to have struck a nerve with the small pack guys, it was not intended... I apologize
