unprotected Panasonic 2900 or Panasonic 3100 or samsung 3000

All the batteries that i am currrently having are panasonic 2900 unprotected.

Now, i am intending to purchase new and higher capacity batteries. There are only 2 options on my list : panasonic 3100 and samsung 3000 (4.35v)

I was wondering which has better performance ?2900, 3100 or 3000?? Does 3100 panasonic performs so much better than 2900 or just a slight different?

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.

does the 200mah make so much different in real life?

yeah, samsung needs special charger to get it fully charged on 4.35v and i do know that some flashlights are having max 4.2v.

It's not the charger that counts. It's weather the drivers can take it. You can charge it with a normal charger up to 4.2V

200mAh does count a lot on lower current draws.

True questions are other, like how's the voltage sag of the 3100 compared to the 2900. Higher currents....

Yeah probably the 3100 does everything slightly better.

Probably the only thing that makes a big difference is to have more batteries.

good then... i think i will stick with my current 2900.. as i see not much different in performance between 2900 and 3100.
