Test/review of Sanyo NCR20700A 3100mAh (Red)
Sanyo NCR20700A 3100mAh (Red)
Official specifications:
This is the new battery size that is slightly larger than 18650 cells. This cell is a high current cell with moderate capacity. The two cells tracks perfectly and can easily deliver the rated current. But the batteries get warm when delivering high current. At maximum rated current they are up to 81°C In this discharge the battery is in free air, i.e. it has better cooling. Conclusion This battery is a very good battery and one of the best high current cell I have tested to date. At lower current there is no reason to use this cell (Instead use the NCR20700B cell), only when the current is above 10A is this cell interesting. Notes and links My test stations is only equipped to handle up to 30A, this means higher current must be done on other equipment. How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries Compare to 18650 and other batteries
