Collection: HAKADI

HAKADI covers cylindrical cells in both chemistries: Li-Ion at 3.7V in 18650 size from 1500mAh to 3350mAh (D1500, C2000, D2000, C2500, D2500, D2600, D2900, C3350), a 3.63V 21700 C4800 at 4800mAh, and LiFePO4 at 3.2V as HKD-3.2V 1500 and 1800 in 18650, 3000 in 21700, 4000 in 26700 and 6000 in 32700.

The letter in the code tells you the job. D parts carry the higher discharge figures — D2500 up to 30A, D2000 and D2600 at 5C — while C parts trade current for capacity, C3350 at 2C and C2500 at 3C.

The LiFePO4 line spans four can sizes, so 3.2V replacements exist for holders built for 18650, 21700, 26700 and 32700 cells.
