Mine didn't come dead. But it was severely imbalanced.
After a few cycles it seems to be ok. I've got nothing to compare it to but I feel it could be better.
I should probably compare my battery analysis to others.
any advice on taking apart the battery on the DX? just ordered the 25-50c 1300 pack but i have no clue how to open the battery portion. just looking for some tips. i dont see a screw to disassemble unless its under the sticker.
