Test of Shockli IMR26650 5500mAh (Black) 2017

This seems to be the latest cell from PLB (高一致性3.7V 5500mAh 镍钴锰酸锂大容量三元动力锂电池|储能锂电池 生产厂家-东莞力朗电池科技有限公司), the OEM behind the LiitoKala 26650-50A. It's current handling ability is a bit worse, yet it probably is the most capacious 26650 in the market. Shockli also released a 5000mAh cell akin to the LiitoKala 26650-50A, probably a lower binned earlier version.
Plenty of runtime if you don't vape too hard.

Cheers
P.S.: seems some sort of internal fuse blew inside the cells after 8 minutes at 30A.

Oh! By the way, substracting the 20A from the 1A curve, averaging the dV at 4 different discharge points plus dividing it by the discharge current delta (19A), effective internal resistance came out at ≈24.54mΩ.
Did you noticed this cell delivers full rated capacity at 20A?
For those finicky of yours, almost 3Ah down to “3.2V”.
No idea where to get them, though.

Cheers my dears
