3) (then) The 3rd pin of just one of the batteries is then connected to N900 to give normal size of resistor to N900 like all fake batteries do?

4) How have you open the battery's case so you can only get cables in without breaking the connectors (and also circuit board out)?

I only have two original BL-5J batteries and I wouldn't want to break them any more than necessary to test them parallel.

5) Can you also charge your two-pack battery through N900's micro-USB-connector?

1) 1 version and it works so haven't made a new one, not that i don't have the parts, i am going to use same setup but with the new battery's that i just got that has 1250mAh each. (see post #1)
2) yes, but can be tricky
3) yes, the resistor is not important for the function of the battery
4) not that hard, there are 2 versions, 1: uses screw's at each end at the connector side, 2: connector is glued on. You can pull the connector from the battery because it has a bit of loose "wire".
5) Yes as long as the battery's are connected in parallel, but cant guarantee if you use 2 battery's and just connect them + + & - - from the connector's, since the - of the battery goes through the circuit (for low voltage cutoff).
