It's not that we don't believe you but i started this thread to find the GOOD vs FAKE battery's and also to build the bigger battery for more runtime, now i have ordered 2x "1600mAh" 18500 cells so far for testing and to see how they fit in the N900.

Still i cannot read some details of what you wrote..

So can you again just write:

* How many battery's/cells are you using? (2 or 4?)

* What kind of battery's? (LiFe/Li-ion/LiPo, 3.2V/3.7V)

* What are the capacity pr battery? (2400mAh?)
