Turnigy LiFEPO4 packs

[fastbaja5b]

I'd like to see some small packs to fit the Mini Slash etc. With a youngun there is a "no soft case lipo" rule in our house, so I'm stuck on Nimh right now.

I'll be testing a 2/3A cell when they come in. They'll be replacing my NiMH and lipos currently being used in my minis. One of the LiFePo4 battery makers that I know said they licensed a new material to make a higher C rate cell. I hope it works good.

I'm not, I wish I could do all the things I have in my head, but I'm not that smart.

You are smart enough to come up with new ideas. It's called being inventive.

I try. The best ones are stuck in my head. I might copy one that I had since Brasil and in the 90's I put it on paper. I'll make a new thread about it and I'll probably add some of my crazy car drawings that I still have. I'll try to get the others from my best friend, but he said he's not letting them go that easy and keeps telling me he forgot where he put them .

How are you liking the info on this LiFePo4 packs from Hobbycity? Have you seen info like it about the MA Green packs?

[snellemin]

Hobbycity list theirs at 40C burst and MA at 60C. Sup with that? 1000 cycles. I haven't been nice enough to my A123's to reach 1000 cycles. I don't think I reached 600 cycles on one pack before it vented. I really want to know it the MA "higher" quality cells have the same voltage drop like the A123's.

The Turnigy Lifepo4 packs I have, appear to be tough as nails.

I have ran a simliar 4S2P A123 setup in a Monster Truck before.

I believe the A123's voltage drop under a load is greater than these. There's just alot more punch.

Thats and understatment! That 2s1p pack you got up to like 195f I think. I remember that thing was so hot, I was impressed by the fact it worked after it cooled down. It lasted almost a year didn't it?

It seems that battery technology is moving pretty fast the last decade, at least faster than it has in a while, I hope it continues.

coolbeans. Good to hear the improvement. Now how hot can they get before they loose capacity.

[snellemin]

Yea it did last a year after it got that hot. I have another 3s1p pack that reached that kinda temp and its still in use. I only get about 1800mah out if now. My 6s1p pack has seen 170+F quite a few times and still does 2300mah. When it was new it took 2500mah.

Anyone seen the new MA 1/16th packs, sad to say I am tempted.......

[Unsullied_Spy]

Anyone seen the similarly sized Turnigy packs for less money than a couple movie tickets?

[fastbaja5b]

If Turnigy had Lifepo4 packs to fit the 1/16th Slash / Revo I'd be all over it!

[Unsullied_Spy]

Any particular reason for needing a LiFePo4? I don't buy anything from MA just on principle.
