Samsung 3000mAh 18650 vs Panasonic 3100mAh 18650

Samsung 3000mAh 18650 vs Panasonic 3100mAh 18650 ???

Thanks a lot bye

Personally I would get the panasonic 3100mah. You need to have a charger that charges the battery to 4.3V to get the most capacity from the samsung. Panasonic can be discharged down the 2.5/2.75V

bye

Not many people have used the Samsung 3000's. So there really isn't a lot of info to pull from. I don't think anyone makes a protected version. As said before you will need a special charger to get them to 4.3v, even then you wont have the capacity of the 3100's

Higher than that even. I believe that for the 3000mAh 18650, the CV voltage is actually 4.35v.

Mmmmm ok i have already a charger but up to 4.20V cut-off ...Xtar WP6 II...by the way, a very good charger....(indepedent pulse and CC/CV charging method).

Do you have a link or model for a similar charger but for charge up to 4.35V ??? Anybody???

thanks

Unfortunately, I am unaware of any consumer grade, cradle type chargers that charge up to 4.35v.

Some of the better hobby charger allow a little adjustment to the peak CV voltage - iCharger for instance allow the peak voltage to be adjusted from 4.20v to 4.30v.

Cottonpickers can make one of his micro chargers to charge to 4.35v.

You can use this to make your own charger, but there is no automatic charge cut-off so you have to monitor charging current...

ok Nice to Cottonpickers micro charger...but i have checked the samsung 3000mAh and the battery is not protected...not protected to discharge under 2.75 and overcharge???

thx

If you can charge it , the Samsung is a sweet sweet battery ...

Otherwise go Panasonic

18650 cells don't come from the factory with a protection circuit - that's the case for Panasonic as well, not just Samsung, and for that matter, is also the case for LG, Sanyo, and any other brand you care to mention. All the protected 18650s have had the protection circuit added by a third party prior to sale. So the Samsung cells you are looking at may not be protected, but that isn't to say that there isn't someone somewhere selling a protected version.
