C1 LiPo upgrade possible

[cf7]

I saw this on ebay.
750 mAh is 5mm thick
950 mah is 6 mm thick
I think the 750 will fit into the C1.

Further..if Innovv remove the battery socket and solder an pig tail socket..there is extra wide space..It will definitely can accommodate a 1000mAh Li-Po

In addition a pig tail lead allows users disconnect battery without complications.

The space is big enough to fit 700mA battery, but the slot for battery block to have battery to insert from back side.
The battery needs to be insert into the case from back side.

You can check with your current battery.

We intended to make 700mA battery inside, but could not put it into the case, so make the current 600mA one.
