Title: Ext. Batt Pack for Z???
Post by: HennaOjisan on November 14, 2003, 08:27:05 pm

Hi,

Has anyone looked at the following external battery pack??? I believe it can be used for the Z at 5V output. It has 8800mAh (5 times that of standard C760 battery!). I\'m starting to get frustrated by the short battery life of C760 with Wifi...

Any other similar alternatives???

Thanks

its near the botom
cheap as hell and just as good
though it may be uglier than that nice silver box (i plan on using a radio shack project box and ordering the batteries (8xAA) off line you want then hooked up 4x2 (4 in serial with the 2 groups in parallel)  that will give you quite a bit of power depending on the cells you chose (2 groups of 4(1.2v*4=4.8) batteries of 3000mah size will give you 6000 mah or 6ah and would be smaller than that thing (you can always add another group if you want more ah\'s)

Here are the packs I made/use:

These are 4000 mah and they are just the right size for attaching to the back of a 5500 with velcro.  You can use a longer cord if you want to go unmounted.  Since the\'re cheap to make, you can build 2 so that you can charge 1 while using the other. Unlike the internal battery, you can hotswap these.
