Yet another battery question!

[Revracer]

FINALLY! I waited forever on my LHS but ended up telling them F you and ordered through mike. Got my batts today and ordered them Tuesday night. Only 4 days. Really fast. And now onto the batteries themselves. My first impression was great. They are built nicely and have nice fat wires coming out of the front. With their 6 cell nimh style wrapping they fit perfectly into all of my cars including my TL-01(old tamiya which can only take 6 cell style packs). I was very happy with that. The blue batteries also look great on my very blue Revo. They came perfectly balanced as well. After finally soldering on some plugs and wiring everything up on my Revo I took it out into the yard. Man was it fast. Much better than 3s. With my two speed still working, it would pull wheelies when it shifted gears. Unfortunately after only a few minutes (not even 5...) I had a stripped spur gear. Probably my fault because I knew it had some bad teeth and was going to go soon. I put one into my Yokomo TC after that and these are tremendously faster compared to my DTX 4200 nimh packs. Very very noticable difference. They also stayed perfectly balanced which might change after a few cycles but after one cycle I was extremely impressed. Hopefully will be getting a new spur gear soon and will let y'all know how it goes then.

*Maybe not, these packs are totally underrated, as I said earlier they blow my FP 4900s out of the water. I have had some drivetrain issues I never expected because of the Swifts. They say 20C, I say more like 30-35C.

These packs have no mercy and continue to impress me way beyond their price point!

I suppose the money saved on these packs may be made up for in repair parts cost..... but I am NOT complaining!

The new generation of "cheap" lipos are mindblowing- let the devastation begin hehe.

Well I believe that. In my Yokomo, these packs were incredibly fast compared to my Nimh packs. I was utterly impressed with these packs and will likely order some more. Two for my revo and two more for my other cars. But my revo was a little torn up in the drivetrain. The slipper plate was cracked and the pads a little worn out and a few teeth missing from the spur. So that deffinitly increased the likelyhood of stripping gears and all. I am going up to the dreaded LHS tomorrow to pick up new pads, plate, and spur.

"incredibly fast compared to my Nimh packs"

They must be. And you can feel good about not having spent tons on garbage overpriced lipos to begin with.

Forgot to mention I have been charging the Swifts at 2C (8 amps) and had no issues at all, they do maintain perfect balance at over 25 cycles and performance is actually improving with each run. Which is scary.

What part will blow out next?

[Revracer]

My charger isn't capable of 8A charging so I will just stick with 4A. It doesn't take too long to charge so its not a big issue. I forgot to mention as well that both of my packs together weigh less than one of my DTX packs. I knew lipo was lighter but the fact that two are less than one suprised me.

[redshift]

You picked a great time to do the lipo changeover, I know these packs, as good as they are will look weak in a year with the advances in lipos. For now they are as good as it gets for anything that uses the classic 6 cell configuration. That makes them priceless as far as I am concerned!

1C is perfectly adequate Revracer, just wanted people to know they are very capable of 2C charge rates.

I used a maxamps for well over a year and have used venoms and SMC before(friends who had them). These packs are far superior to maxamps and venom packs IMO. These may be old and weak in a year but by the time something substantially better than these come out I will have gotten many runs out of these and will deffinitly have gotten my moneys worth. Just like trucks... They advance constantly, but you make sure you get your moneys worth before you get something "better".

[Revracer]

Aright SO I have about 5 runs or so in my revo. After finally tuning and everything this thingis amazing and these batteries are incredible! My current setup is Mega ACn22/30/1(yes thats a 3500kv motor) and a Mamba Max ESC with twin 4000 Hyperion CLASSIC packs. I am running a 14/40 gearing with close ratio and two speed still engaged. The truck is insane. At a little over half throttle, when it changes gears the truck does a wheelie. I dont have exact temps but can say after a few high speed runs and bashing after a full battery, nothing is too hot. Motor and ESC can be touche for about 4-6 seconds and the batteries are barely warm to the touch. Damage report... Went through my first spur and melted a slipper, stripped out two wheels and the hexes. The truck is faster than it has ever been and has what seems like endless torque. And like many people say. Your system is only as good as your batts. So these must be some damn good batts...

Over 30 cycles on mine and they still throw my 14 1/2 pounder around like a dirty diaper.

Glad you are having similar experience!

BUY THESE PACKS!!!!

[Revracer]

I am deffinitly having a good experience with these packs. Worth every penny and then some! I highly recomend these to anyone who is searching for new packs. By far the best batteries I've ever driven. Have you noticed heat issues with your ESC though? I ran DTX 4200 packs a couple of times in the truck and never had heat issues. My Mamba Max thermalled today though. It kind of suprised me.

Also have balance charged each pack each time(I just leave my balancer pluged into my charger all the time. That isnt bad for them is it?) But anyway, the balancer has done nothing so far. Packs have stayed perfectly balanced.

Rev I'm having trouble with PM, in answer to your question, yes I believe these packs will deliver substantially more than they are rated for. 40-45 mph should be no problem in bursts. You will suck 'em down faster of course. I have run mine (have 2 pair) as hard as I ever will and they get lukewarm. There isn't even a warm up like my FP Evo25's had, they ended over 120 degrees alot- but have sold those because I was so impressed with the Swift Classics.

"I ran DTX 4200 packs a couple of times in the truck and never had heat issues. My Mamba Max thermalled today though. It kind of suprised me."

Your limitation was your batteries before, now it will be your MM. A Medusa 70 or 80 or similar motor may put you into MMM territory, but yes the batteries are capable I have no doubt.

I still am running one, in a HEAVY rig (with a fan) and I actually have no plans to get a MMM, even though I am pushing the MM close to the limit. I had planned on a MMM but got caught in the waiting game last summer and went with the MM and have no regrets. Actually love it cuz it's smaller.

" I just leave my balancer pluged into my charger all the time. That isnt bad for them is it?"

I think that's common, but I've only owned a balance charger so someone else might wanna chime in.

[Revracer]

It suprises me though because my motor is only rated to pull 70A... I installed a fan and now its much cooler. Didnt thermal this time... But then again I didnt run as long because of my snapped motor shaft...
