Are the Efest protected batteries the new Panasonic NCR18650B 3400mah? If so, these are the only ones I can find available, and for quite a reasonable price(assuming you buy several, since the shipping is added in extra). This is actually cheaper than the Xtar 3100 from the same seller.
The “higher end” cells like Orbtronic are $27.00/each. OUCH!
Efest: At that price they are very appealing, might have to get a couple some time. Any idea of when you will have unprotected Panasonic 3400mAh cells in stock and the price? Thanks!
