The Panasonic 3100 have an extra capacity of 200mAh over your 2900mAh Panasonics. Both have same cut-offs and full charge voltage.
For the Samsung you need a special charger to charge the batteries, and if your driver cannot handle just a little extra voltage, maybe it get's burned, especially in multiple configuration, where the voltage keeps adding. Except when you have some buck drivers. If you want to charge the Samsung 3000 only until 4.2V you'll get a lower capacity. Which will probably be around 2800mAh.
