Whilst looking at alternatives to creating an external battery pack for my SL5500, it occurred to me that the Z battery is basically the same as any number of 3.6v Li-ion mobile phone batteries, which can be picked up dirt cheap from the likes of eBay.
What I\'m wondering is if the charging circuit of the Z is going to be stressed by, say, attaching 3 batteries in parallel to the existing one (maybe drilling a small hole in the battery cover to allow connecton to the internal battery connector). Any ideas?
I\'d like to sick them along the back of the Z side-by-side, should be good for 3000mAh without adding too much depth to the unit.
