All the cells are 1600mAh (milliamp-hours). Each cell is 3.7v nominal and they are wired in series to give 11.1v.

Separating the cells is possible not easy because they are pretty firmly attached so it's likely you will bend the cells trying to split them, plus the terminals are usually soldered onto a circuit board on the end of the battery.

Bear in mind that you can get a new 1600mAh liPo for about $9 so it's not the end of the world to ditch it.

From what I've been able to determine, these cells have tabs that are not easy to solder to. With the risk of fire, methinks its not worth while

If you're after cells that can easily be soldered to, check out these A123 cells, at $9.99 each, from a supplier located in the USA. Both club members and I have purchased well over 100 cells from this supplier in the past year, no one has had any sort of a problem or issue with voltmanbatteries.

Actually they are very easy to solder to and because they are just thin metal tabs they don't transmit much heat back into the battery. The danger with them is tearing them off when you separate the cells as they are quite fragile.
