Bottom Line: The Sanyo 20700A is the second newly available 20mm x 70mm cell I have tested. The first was the 20700B (<a href="https://www.e-cigarette-forum.com/forum/threads/sanyo-20700b-4000mah-20700-bench-test-results-a-peek-at-the-future.775809/”>https://www.e-cigarette-forum.com/forum/threads/sanyo-20700b-4000mah-20700-bench-test-results-a-peek-at-the-future.775809/), a great high capacity cell I rated at 16A 4000mAh. At 10A-15A it runs about 25% longer than the LG HG2.
This 20700A is a true high performance cell that I am rating at a cool-running 30A 3100mAh. It performed well against the top 18650 cells for performance, vaping time, and safety (high amp rating). The 20700A…
…hits as hard as the Sony VTC5A at the start and easily holds its voltage up higher for considerably longer.
…runs about 20% longer than the VTC6 at 20A continuous down to 3.2V.
…runs 5°C cooler than the LG HB6 at 20A continuous and for about 230% longer. Yes, 230%.
While this cell will only fit in a custom battery sled it did just fit in the Xtar and Efest chargers I tested it in. I cannot say if it will fit in any 18650 charger. Otherwise it's charged at 4.2V just like our 18650's. It's "standard" charging rate is 2.2A so 2A charging is no problem and won't decrease its overall life. I am giving the Sanyo 20700A a maximum vaping amps (MVA) rating of 45A.
