18650 Pack

Keep in mind that the Lithium packs do series/parallel switching from 12 to 24v to accomidate charging at 12v (4 series cells). However they are driven at 24v (8 series cells). As such the charging numbers should be divided in half for their proper 24v capacity... Graphs to come...

I Believe that this is the same battery used in an old Motorola Timeport Cellphone that I purchased Dec. 7 2000. This phone was used for about 9 months durring which time it went for a swim in a lake, shorting out and overheating, but it did continue to work. It sat unused for about 2 years. (See the photos on the right side) Now, Oct. 2004, being some 3 years old I'm cycling it to see how it compaires to the above cells...
