a123 ? a123systems web site indicates 5min re-charge ?

hi,,,

http://www.a123systems.com/html/tech/power.html,,, indicates 5 min re-charge ?

"A unique feature of A123Systems’ M1 cells is their ability to charge to high capacity in 5 minutes or less. That’s a significant improvement over traditional Li Ion, which typically requires more than 90 minutes to reach a similar level of charge. This unique capability offers a new level of convenience for users of cordless products"

so what gives ? ,,,,, never heard of this in the heli world ?

i know our field chargers have limited max charge current...

so lets talk about the big power supplies charging these cells under ideal conditions .

has anyone seen anything like 5 min ? so what would the calculation look like for this to work,,, what would be the initial charge rate ?


now if you look more on web site,,, then see these:

http://www.a123systems.com/html/products/cells.html

Nominal voltage: 3.3V

Nominal capacity: 2.3Ah

Typical fast charge current: 10A to 3.6V CCCV

=====================================

so at 10 amps ,,, TYPICAL ,,, how long to charge ??

what formula used to calc time at 10 amp ?

===================================
now with that said,,,, again assume we have unlimited high current chargers,,,, what is the quickest we want to charge these on daily bases ?

============================================

thanks for the help,,, my end goal is getting charger with capacity to charge at the fastest recommended rate for these cells in large packs like 10s..
