So basically it's impossible to get bigger capacity without sacrificing the size?
Because i don't think mugen allows buying backcover separately do they?

oh btw, the steps to mod 2 japods is the same as your other mod right? Do you mind upload the japod pics and explain how you do the mods in page 1? thanks

But yes it's the same procedure as mod 2 (2x 'christgift').

quick guide
Strip the battery's down, be careful when removing the top cover (connector on the battery), small shorts can accrue when doing this but as long as it is only for a second it will not damage the battery.
when both battery's are bare (don't need to remove the sticker/cover) put them against each other and tape them together.
Now comes the part where the soldering begins:
Take some wire and solder a long piece (5cm/2inch) this will be used to connect the + to + & - to - between the 2 battery's.
Make sure you make it as flush as possible as space is not in big supply in the battery space in the phone, USE CAUTION when handling the - on the battery's, solder only long enough to make the connection or you will ruin the battery, and also don't short it to the metal frame of the battery's since this is +.
In my dual japod config i used the connector from the very cheap battery from DX since it is very hard to take apart the japod connector.
To connect the connector to the new dual battery is pretty easy just solder wires to where the battery wires normally go. (or use B+ & B- markings)
I cut down over where i soldered the wires in the connector so that the wires took as up as little space as possible.
The bottom of the battery's has a thick plastic piece that helps to isolate the metal of the battery (witch is +) from the metal of the phone (witch is -), if space is very tight you can remove them and substitute with paper or tape.

Look to the pictures at post #2 for more help.
i hope this helps else please post and i will try to make it more simple or get more details on here.

Your information is very useful, I really appreciate it.
Would you please post or send me the picture of your connector for dual japod? and installation pictures?


anyway, I got the link of high capacity battery (2.800 mAH) as follows:
http://priceangels.com/2800mAh_3.7V_...00_p11958.html

Can I use it for N900? have you tested it?

Thank you

I have only tested the battery's in the list on Post #1.
The battery you link to looks nice, BUT it is probably the same upside down connector since it is made specific for the 5800 look to my 1930mAh E_Cell battery test thread for a similar battery and why it would not work in the N900

1930mAh BL-5J Battery from e_cell (EBAY)
