The standard (on this site) way of soldering the cells is almost guaranteed to destroy the capacity.
If you measured the capacity as soon as you have soldered the cells and then 30 days could there also a chance of damage due to the heat. If not, then my guess is the cells have a combined capacity of 2000mAh from damage. This is what happened to me. Heat solder damage.

Out of four soldered packs only one measures at double of a single paired up.

I now leave the cell protector circuit on the cell. Gently prying off the plastic cover. Gently cut a channel for the wire in the bottom plastic cover, hot melt over the top. The gold contacts get carefully snipped to a nice flat shape and very very easy to solder too.

The top cell needs to be placed a little further rearward for the mugen cover to fit as you still have the protection circuitry but sans plastic cover and with hot melt for protection.
