I have never had, nor seen a lipo burn up in person, only videos online of people shorting them out to show what can happen. I have flown airplanes using LiPo batteries for a few years now and have seen quite a few planes using them crash with no explosive results. I am not saying the A123 packs are bad at all. I just have a dozen or so lipos that fit my mini and plan to use those... If I saw any REAL advantage to using A123 packs, I would. Reasons that you state are not good enough for me. I can take faster charge times and higher burst ratings as TRUE advantages... Not simply saying that they are tolerant to irresponsible charging. I take care of my batteries and have nice chargers meant for LiPo's that don't overcharge the packs I don't put myself at risk by being so careless. I have also never popped a nicad or nimh pack by overcharging, nor puffed a lipo... years and years in this hobby and I have never had a battery fail because of my charging them, only dead cells due to thier known lifespan. If you don't want a lipo to burn, you simply don't short-out or overcharge the pack - Not hard things to do (use responsibly and as intended).

- Thank you Mr. Mugen for pointing out REAL advantages of these A123 packs, I will certainly plan on trying these out in the future.

Some people dont know what "C" ratings are and overdraw their lipo's as well. This ruins them. I had a few eye openers this way. Since then I do all math first. And use a watts up meter to test all draw before applying them.

They should fit a mini T, two cells side by side are equal to 4 2/3a size cells, which is what the mini T uses. Im not saying to do it and it will work for sure - they might be just a little bit taller.. mr. mugen would know.

I went to menards today and most of the black and decker stuff including these batteries were on sale for i think 16.99 or 15.99, but Im guessing the sale will probably end tomorrow.

you could run a 3s pack in a mini t...

If anyone still needs a reason to buy these cells, look at this. http://youtube.com/watch?v=A9ayuFBDrSg Its just a little durability test.

I'm not worried about my packs exploding just how cheap they are.

hey i know im kinda stealing the thread for a sec, but...

1 can i use a 2s 10C 7.4v lipo for a brp with a standard servo and a 16D motor?

and will a normal radio shack 8cell 9.6 1000mah niCD work for this setup? the esc can handle 9.6.

thanks, when i have money, lith ion is the first upgrade.

You should be able to. Remember the LVC. Depending on the esc your planning to use you may not have one (most likely not). You do not want to run your lipo below 6v if possible. How many mah is your 2s lipo?

I dont know about the triton, but I think I found a pretty good a123 charger.

http://www.sussex-model-centre.co.uk/shopexd.asp?id=23944

It is 60.00 usd. Does anybody know anything about this charger? This may push me into buying a123s for my savage

I don't think the triton is able to charge A123 cells. The specs from tower do not mention anything about LifePO4 (a123) capabilities.

The Triton 2 has the option to charge LiIon cells. But not the original Triton.

I dont think that li-ion cells are the same thing as a123 cells. I emailed mrc to ask if my super brain charged a123s and he said it cant, but on the box it says that it charges li-ion, and I'm sure it can, but it's not the same thing as a123. Someone could PM a battery moderator: http://www.rcuniverse.com/community/profile.cfm?section=profile&forum=1&memid=23611

its 1000mah and im using a no limit esc. so its kind of peppy at 660A continuos and 2400A peak... im not sure how much a 16D motor will use, or if its a little too much.

i put it in a radio shack truck (540 motor and weighs a ton) for 5 minuts running full speed in grass and street and it got just a little warm like if it was in the hellie it came from.

and im thinking about using a 1000mah 9.6 8cell, but worried if its too much for the little motor.
