What about the Hammerhead Eagle iThrust?

:lol:

Ordered one 3S pack for my Slash. (VXL and 5700kV motors) Should fit nicely since 3S lipo is a bit insane. :mdr:

These Turnigy 4500mAh 2S2P Pack are little bit too thick for me, 25mm...are there any 6,6V packs under 23-24mm?

Can these packs be charged using A123 Sonic charger?

Nice show Neil. Thanks for sharing that with us. I have missed the wit of the English TV shows. I used to live in Holy Loch, Scotland 1977-1980 & 1985-1990 (2 X US Navy tours). I really miss the TV and the fish & chip.

Anyway that show was brilliant to watch. Funny bunch of coconuts those three. It really does make the idea of creating your own electric 1:1 vehicle seem not so hard. Of course their sense of design and ingenuity are pretty lacking. Still very funny show.

Not that I know of (r/c spec ones at any rate), and not easily.

You'd need a lower capacity pack to make it thinner, but the majority of whats on the market currently all seem to be the same 2250mah packs- paralleled to make 4500mah. Lutach would be the guy to talk to as he's trialling various new packs, but they wont be in general circulation for a while; will have to go lipo or see if you can enlarge your battery trays some how.

As for the charger, you will need to make an adaptor for the balance taps as the hobbycity packs use the common jst-xh ( align ) style plugs, where as the A123 charger has its own weird little setup and different wiring configuration- you may be better off with just picking up a cheap (sub ~$50) charger with a built-in powersupply and balancer- look up the Thunder AC6 for a good example.

Good lord... so much data and rambling in this thread that I've gotten to the end and have no idea what was accomplished here. What's the bottom line here fellas? That the cheap Turnigy LiFe packs are every bit as good as the MA packs? Or did we determine something else? Let's summerize!

Some more data.

Summary:

MA suck balls, long-live Turnigy Lifepo4 cells!

They are every bit as good, if not better due to the much lower pricing.

Thanks for the data guys !
Now I'm waiting LifePo4 Turnigy packs with more mAh :mdr:

Is hobbyking.com the only place that sells them? 2s that I need are out of stock for a while.

So far I've only found them on hobbyking regularly. I did see that there was 1 person selling them on Ebay a while back...

Maxamps
 

MAXAMPS also sells them, but at a hefty price.

Hefty price is right, worked out at $100 AUD to get a pair of Lifepo4 packs (2s 1100mah) for my Mini Revo, but that said they work well and seem to hold good balance, run it till it dies, charge at 7 amps and in 10 minutes off we go again.

5000 cycle warranty, and I'm counting lol :)

If
 

If they do last that long the value would seem to be a pretty good deal, don't you think? I know Maxamps has not developed a very good rep on here, but 5,000 cycles would prove to be a boost in the right direction.

By the time you get to 5,000 cycles the battery tech will have moved on again and we'll all be using LI-MP-MN-$C packs or something equally ridiculous. You reckon Maxamps actually counts on anyone claiming on that guarantee?

"Well, these batteries should last for 5000 cycles so for them to have died at 500 you must have abused them"

Baseline is, you are paying a massive premium for a guarantee that means nothing in the real world.

Even if these Turnigy Lifepo4 cells aren't the same or slightly lower quality than the Maxamps cells, is it worth paying a $140 premium for a 3s2p 4500 pack that MAY last a few more cycles. The answer is no. It is not.
