Uh oh, did I ruin my SMC Lipo's?

I would say that is a fair trial there. If it's consistent at 3.2v cutoff for 8-10 charges I would say everything is okay. But if you loose 100mah or more across the 8-10 charge cycles keeping the lvc the same at 3.2v then you are over stressing your packs.

Linc, I know lipo's are not like A123's for cycle life, but you get more than 100 cycles out of them don't you?

Another example... say if you DID get 100 cycles from 80% DOD, then you can expect somewhere around 150 cycles at 60% DOD. And if you are really crazy about total calender minutes out of your pack, you can always use 10% DOD and get something like 2000 cycles from it.

Also, charging rate has alot to do with it as well, same with operating temp (big time)... so the newer cells that run cooler and can handle 5C charging are definitely going to last a good deal... if kept to running your typical load along with 1C charging.

Yep, I figure you can get at least 150 cycles, but even at 100 cycles the cost savings over nitro is massive.
