a123 or lipo.... and other ?s

[t-maxxracer32]

hey ive been thinking of getting some diff kind of batteries (ditching the nimh) and i have come to the conclusion that these are really the only other way to go.. lol.. so ive been looking around and i think i have a decent pros and cons list

LIPO PROS
3.6v per cell
LONG run time
can keep my ice charger and use for these

LIPO CONS
not the best for bashing (hazardous)
EXPENSIVE
need to be handled with care
normal long charge time
365 grams

A123 PROS
260 grams
very durable
15min charge time
can get 2 batts and a charger for 200 bucks

A123 CONS
short run times
are not stick packs so there not a direct fit
needs its own charger


those are the only cons i could find for the A123 cells.

i dont feel like spending 120 for the 8000 3s2p packs and end up maybe breaking them.
but on the other hand i dont want to have my ice charger go to waste
im going to be running this in a mm5700 rusty to keep that in mind.
what setup do you think would be best for me? the 3s1p hypersonic starter set or getting 2 8000mah 3s2p lipos? (or some other lipos but id rather these for the runtimes)

also if i get the rcm g10 chassis for the rusty will i be able to fit the lipos in? also can i fit the a123 cells in it?

also another question.... i had was for my ice charger what is the best cheapest power supply i can buy?

thansk ALOT again guys!

Run times are not much behind the Li-po's but the voltage is so they feel "less punchy".

4s li-po is 14.8v nominal and 16v freshly charged. 4s A123 is 13.2v and roughly 14.8 freshly charged.

The sizes are a bit odd and fitment can be an issue, but they are basher friendly and friendly on the wallet! they also hold their voltage across the discharge timeline very well (voltage does not drop off much as you use up the pack)

[t-maxxracer32]

so pretty much getting that starter kit on a123 racing you think would be better for me? how would the run times be on these? they are only 2300 mah so idk what to expect.. but if i get 2 of them in the starter kit and the charger charges them in 15 min it doesnt matter even if there only a 7-10 min runtime.

also will i need a power supply for the kit on a123racing?

thanks!

You can get the 2s-2p's which are 6.6v and 4600mah or the 3s1p's which are 9.9v but only 2300 mah.

Not sure what will fit the rusty. Is that what you're putting it in?

[t-maxxracer32]

ya its going into a rusty. i was going to get the rcm g10 chassis but after looking at it i dont knowhow the a123 packs would fit into it...

im going to get the 9.9v because my 7.2v packs dont compare AT ALL to my 8.4v pack. i dont really like running my 6 cells anymore because of that so making it a 6.6v would be pointless. but since i can charge the batts in 15 min it doesnt matter what the runtime will be.

btw, if you're using a low watt drawfrom the packs you can use their "turbo" pack which allows you to select the nominal voltage. They are limited though. Probably around 300watt draw. You'll need to inquire about that I don't have the ratings handy.

Personally, I would go with Lipo. They are better in almost every way instead of cost and their hazerdous nature.

However, with a proper LVC, the only hazard is physical damage. In a rusty, if you have them properly secured, it will be nearly impossible to damage them unless something actually enters through the body and physically hits them. The other possibility is breaking your chassis, in which you will probably have other, more expensive problems if you happen to accomplish that.

I have just gotten the 2S2P 8000mah packs for my G2R and they are insane. I'm very happy with them so far (I've only ran them for about 5 minutes). I'm hitting the track tomorrow to put them to the test.

[t-maxxracer32]

why are lipos better than the a123 cells?

can ya give me a pros and cons list bp?

also procharged i saw those turbo packs but people said they dont offer enough draw or something. i like how yo ucan change it to what you want but people said something about them sucks and idk what it was but ya...

also how long does it take to charge the 8000 mah? also if i did get the
2s2p it would be 7.2v but would it be more powerfull than a regular 6 cell gp3300? because i LOVE the power of the 7 cell so i dont really want anything less.

[Sylvester]

T-maxx, lipos are better because of the high mah, higher voltage and the more watts they can put out... But the a123s are a bit better in the durability department..

If you charge @ 1C the 8000mah will take 1 hour and 20 minutes to charge.
Yes, the 2s2p lipo will be more powerful than a 6 cell gp3300. It will probably even be more than a 7 cell pack!

[phildogg]

I would get the 6000 lipo from maxamps myself.. lighter and still plenty of runtime..

[t-maxxracer32]

o sweet.... well as far as the mah goes... if i can charge the a123 packs in 15 minutes the runtime doesnt really matter as long as its around 7 minutes or more... is it? also how will the 3s1p 2300mah a123 cell compare to the 2s2p 8000 mah lipo as far as power goes

[Sylvester]

the 8000mah would have alot more power and more than twice the runtime.
Imo go for lipo.

[t-maxxracer32]

so wait a 7.4v lipo would have more power than a 9.9v a123 cell?

[t-maxxracer32]

what could i expect the runtime for the 6000 to be?

[t-maxxracer32]

think someoen can give me a good pros and cons for the a123 cells? because i dont see too many cons..
