Trackpower.. yes, no?

[skellyo]

Just order my Trakpowers! :D

I ordered 3 packs and 2 of the balancers. It was news to me to find out that they have a specific balancer for the Trakpower packs that comes with the necessary harness adapter...and it's cheaper too...$44.95 versus $49.95 + $6.95.

I told him about this site and he seemed interested to see if Mike wanted to become a dealer for them. That would be nice!

Also, to anyone else running Trakpowers...the guy at Duralite I talked to was interested in photos of the Trakpower battery packs in the vehicles. Apparently they're working on a new website and would like some nice gallery photos.

Cool!

Great buy! Makes me wanna order up some right now!

[captain harlock]

Yep! Those are the ones.

If you are going to use them for the trakpower, you'll need three males and three females.( two for the pack, two for the controller and two for the balancer).

However, if you're gonna use the 4mm for the balancer, this means you won't be able to charge the flightpower packs if you'll use the 5.5mm with them.
You either have to use the 4mm generally or make an adapter to connect between the FP packs and V-bal.

I've spoken to Mike about the FlightPower packs, too. He seems interested, but not that much. Someone must shoot him another e-mail about them.

[Sylvester]

Or i might use deans for the packs going to the esc.. will use deans on the balancer as well.

[captain harlock]

That's a good option too.

From what I gathered talking to the guy from Duralite, he was going to contact Mike himself.

[captain harlock]

That would be nice. I'll remind Mike about the FP thing.
These packs MUST be carried in the rc-monster store.

Ill see to that! I dont know why Mike wouldnt want to carry these packs, as im sure alot of people would buy off him since A class service with A class batteries = an amazingly happy customer:)

[captain harlock]

Well, let's give him a push, then.

I'm thinking about going lipo and geting some maxamp 8000's and/or the trackpowers, but then I saw on their website (trackpower) that they can only do 100 race worthy cycles or 200+ practice/mixed cycles. I don't really want to spend that much money on batteries if their not going to last that long (2 packs for my E-maxx). That would cost more per run than using nitro fuel.
I thought one of the good things about lipo was that they lasted a lot longer than other batteries (1000 plus cycles), but 100 cycles is less than nimh.
Am I missing something?
Does anyone have some old trackpowers (or any lipo)? How do they go after a few hundred cycles?
thanks.

I don't think they are worse than other lipos... they must be under-rating the cycle life. Lipos don't just die after xxx cycles... they slowly lose capacity.

Did they say what capacity the will be after 100 cycles? They may be basing their #'s on a very high % like 90-95% capacity yield.

Also, keep in mind that typical use, like racing... many 'cycles' are only partial discharge.... like 25%... 50%... 70%... etc. Cycle life is much higher when they are only partially discharged. Their estimates likely are for full discharge cycles.

They way I look at lipos is that I will be ready for newer better packs, or I will goof up and destroy them, before I wear them out. I really don't get to run my cars that much, lol...

My 8000mah pack has about 6 cycles on it and none of them probably went beyond 50% discharge.... my 12000 pack has maybe a dozen runs... with only a couple deep discharges. I sure hope I get to run the crap out of them this summer. If I get 100 runs total for the summer I will be happy. :D

Perhaps Dafni can shine his light on this one; he is using the 5S2P 3700 FP packs with great succes, and they are still going strong (as is the FP pack he is using in his rc18t) and he uses it a lot.

[Dafni]

2 facts I learned along the way:
-lipo packs should stay cool. The warmer they get, the sooner you'll see a decrease in capacity and performance.
-even just a 1P 3700 FP setup does not get warm at all in my truck, but a Maxamps 8000 setup in the same place does noticeably get warm. Not hot, just warm. Makes you think. They claim the same discharge rate, and even have more than twice the capacity. Still they get warmer.

As for cycle life, a good Lipo should outlast any Nickel cell without problems.
And Patrick, how long do you think will it take you to get "a few hundred cycles" on a pack? Just curious.

nimh's are getting quite poor after 70-80 runs. they take about 70 percent of the energy. They don't really like the spikes the monsters are loading them with.
