Question about Lifepo4 or a123 cells and racing
 

Just wondering if maxamps or A123 racing with 2250mah 6.6v LiFe battery will have enough capacity for a 6min 4wd buggy race?(i have a durga)

I think i might have to go with 1 lower wind in order to compensate for the lower voltage, so maybe a 5.5t!??(its a slippery track)

well, it depends on the type of track etc, but it would be close.

2250 mah, 6 mins, very doubtful with a 5.5t motor, remembering u'll already be going slower than u were with a lipo/nimh in the car anyway, and u'd have to hope the battery actually put out the full 2250mah and dont do any practise laps, i run 17.5 stock and usually use around 1800 mah in a 5 min race, most mod guys use similar amounts in a 5 min race, adding an extra 20% race time would be close, expect to dump a bit unless ur soft on the trigger

I use ~2700mah in 7 minutes on average on high grip carpet tracks with a 5,5T, so I'd say its cutting it too close.

Life or lithium ion will be the next battery technology.
I just dont much care for the Lipo era. A123's are good cells too.
A123 batteries are used in hospitals. Now they are for RC.
A123 have been out for a while, while Life is just getting started.
It's just impossible to make a life or A123 into a saddle pack
without modifying your chassis.:thumbdown:

That's why Ive stayed with high capacity nimh for now.
I run 5000 elite nimh packs in my 501x. Have good punch and lifespan.
I keep up with the Lipo guys fairly easy. :)
After all it all comes down to the driver, not the pack your running.

Thanks for all your replies il go with the 4000 or 4250mah LiFePo4 maybe reedy or Maxamps model then!
