Dude post a link of what you are talking. At least 3 people went to A123 site and didnt find anything new.

The OP is right guys...A123 developed a stickpack Li-ion pack with their technology.

Only problem is its 2200mAh (which translates to about 3100 real mAh roughly given the efficiency and energy density of the packs). Im sure the 30c rating helps make up for the lower voltage somehow...regardless...

RC car action showed them in a flyer. RCCA April 2008 page 155.In the "Speed-T" review.


The pack's specs are
6.6v
2200mAh
2s2p
Max Current Cont: 65a (30c)
Max Current Pulse: 130a (60c)
Size (LxHxW) = 136x22x45mm
weight: 200g

im suprised party_wagon didnt start this thread

in addition, i know a guy that races using the 2300mAh packs. They are about equivalent to a 3300 NIMH. He can run a full 6 min heat using an old Dr.VonQuick motor (read: not as efficient as today's motors) no problem the whole race.

Also, if A123 steps it up and shrinks their Turbo modules, they can be onto something (but they'd have to increase mAh as the increased voltage if u switch to 7.2 will likely lower runtime).

Seems 2s2p config with the B&D battery party_wagon mentioned. Like i said, to expensive for me, specially considering they will be ilegal for most of the races i attend.

Maybe with Enerland help A123 prices go down soon.

custom packs are crazy affordable, at least Thedunemaster agrees :P

Those are not the new 1100 mha batery, are the old M1 2300 mha, wich is to wide to fit most touring cars.

i know that, but most people were complaining on the prices of the packs (and the only prices available right now are for those that i showed) which as you can see can be had for cheaper elsewhere.

I looked for the new brick packs everywhere after I picked up the RC driver with the IFS review in it.

I haven't turned up anything.

Someone might be asleep at the wheel.

Just a thought, the volume of a A123 2300 MAH 5/4 C cell is nearly identical to a MaxAmps 4000HV lipo cell. Don

Try the link below.
These may be the batteries the first post was about. Not sure.

I am not very literate on the subject of battery techs but am I right in thinking that when used with the (turbo)module these 4600 batteries have adjustable voltage between 7.2 And 10.8v.

I assume this is what you are talking about?

Not bloody likely. A123 is an order of magnitude bigger than Enerland. A123's hybrid car and power tool contracts dwarf Enerland's almost exclusive undiversified RC market. A123 gobbled up Enerland - not the other way around.

All the links that have been posted are the same old batteries they have always had. Am I missing something?

linger: no doubt.. the r/c market is a drop in the bucket compared to the real cars

The 2200 6.6V stick packs have been out for a few months. The new "Bricks" are very similar in size and shape as other LiPO's

What is new about these packs are the fact they maybe using "Soft" cells. Soft cells are cheaper and easier to manipulate the size than a cylindrical metal cased battery. Also by using custom sized soft-cells, more battery can be fitted into the battery tray as with LiPO bricks. Using cylindrical cells, voids and gaps are created and that means less battery, less run time and less punch.

A123RACING.COM and A123SYSTEMS.COM have not updated their site in about a year but for those that happen to be at larger hobby shows you may spot the new packs.

I wish I had a pick of the new "Brick" packs, I only have pics of the "Stick" packs made with cylindrical cells.

Well Dang... that first pic sure looks to me like a true lipo-brick shape pack.

Doesn't look like it could be the old round A123 cells inside a box... it would be bigger than it is.

This is pretty cool, IF the price is good. They need to remember their packs are lower voltage so they are still the odd ball...

Now I wonder how "tough" and "safe" these are compared to the round cells?

Isn't the 21.5 for 7.4V lipo to compete with traditional 4 cell, 4.8V stock? And the 17.5 for 6 cell, 7.2V, or lipo? If so then 6.6V with 17.5 would seem, at least on the face of it, to be slow. Granted, specs don't tell everything, how well do the batteries maintain voltage under load and all. But it's not like lipos suck in that regard.
