brushless or li-po

ok cheers :027: i will stick with them.. do you reckon one or two of these beasts is best + ther only $35 :004:

i will go lipo as they do draw alot, i think watts is around 500 ish so on 22V that is ~22 amps
but i know when i put one 7.2V pack on just to test it out.. it started smoking just sitting ther not yet moving when i pushed the throttle :007: i dont think the pack can deliever nearly 70A

Lipos it is then :027: now to find a decent charger etc

I would only use one. Lighter weight plus less amp draw on the batteries. Right now I am running a single 820 motor in my jugg 2 on 6s A123 cells and it is a monster.

sounds good. plus more room to mount everything :004:

how are the A123 cells actually i was looking at them before i saw the lipo packs, are they better or worse ???

[lydiasdad]

A123's have their pro's and con's when compared to li-po packs. The biggest pro is durability. They can be charged at up to 10 amps and you don't need a lvc to protect from over discharge. Their capacity is only 2300mah per cell though. Good li-po cells can put out more power with less weight. A123 cells can be more diffuclt to mount also although that varys from vehicle to vehicle. I went from gp 3300's to these A123 cells and I am very happy with them.

sounds interesting, but ya i saw they only make 2300 cells, but you can paralell them right?
i might look into them also, i saw somewhere that they have 60A bursts ?? but if your running them with a 820 motor and ther not getting hot then it sounds good
what kinda charger do you need as they are 3.3V a cell aren;t they :eek:
