Hello Keiichi,

The 621 and 421 include pre-programmed chemIDs for 4.2V, 4.3V and 4.35V chemistries that are appropriate for most standard LiCoO2 batteries. There is no list of certified batteries for the 421 & 621, but considering a 18650 cell is a common cell type, it should work with these parts.

Thanks.
