A123 2200mAh pack!!! - 10.05.2007, 05:50 PM

I bought the new RC Driver magazine and the article on the Tamiya TA-05 IFS they show a A123 2200mAh pack. The funny thing is that it doesn't say anything in A123's website. I also looked in Horizon's website and same story there. One other thing, the TA-05 IFS has a very interesting looking front suspension system.

Good find, I just rechecked and it is a cool looking piece. It almost looks like they went with a flat cell


Work because i gotta, play because i wanna

People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise

It sure looks like a prismatic type cell. The only problem, there is no info on them anywhere.

Could it be one of the A123 packs that Maxamps assembles and re-sells?


Losi 8T 1.0, Savage Flux - XL style, LST XXL, Muggy, 3.3 E-Revo Conversion and sitting outside 425hp, 831 Tq Dodge Ram Turbo Diesel. It SMOKES

The pack in the Tamiya doesn't look like the normal A123 packs. This pack seems much thiner then the usual A123 packs.

Those are 2300mah, I think it looks like a flat cell or an 1100 cell in 2P

I haven't seen the RCDriver article yet - however:
I had an opportunity to use one of those packs a couple months ago in my Associated B4 buggy for local club racing.
It was a 2s2p 1100mah A123 battery pack the same length and width of a normal 6-cell nimh stick pack, and just a little bit shorter. That means it'll fit just about any place you can fit a 6-cell nimh stick pack.
It worked great for the 4 weeks or so that I used it, which included about 20 cycles.

A123 was not ready to release them mainly because their Hypersonic Charger beats the heck out of them when fast charging at 8-10Amps, which shortens battery life. They definitely didn't want to release a battery that would have shortened life from using their own charger. If they are showing the pack in a magazine, maybe they have a solution to the charging issue. I certainly hope so - I really want to use the pack in my race vehicles :)

Did A123 let you take pictures or they made you sign a form that wouldn't allow you to do it? How long did one charged pack last in race conditions? What is the discharge rate of the pack? There are a few chargers in the market right now that are capable of charging A123 cells.
