This 8-bay charger supports lithium ion and nickel metal hydride cells, and can charge up to 2 cells at 3 amps, up to 4 cells at 2 amps, and up to 8 cells at 1 amp. LiFePO4 can also be charged if the charger is in Storage mode. Sodium ion can also be mostly charged in Storage mode.
Cells can be graded (charged, discharged and capacity tested, then charged again) in Grad mode.

Things I found out after I made this video:

In storage mode, nickel metal hydride is first charged fully, then discharged to 1.29 volts.

In storage mode, sodium ion is treated as NiMH until it reaches 2 volts. Between 2 volts and 2.5 volts, sodium ion is treated as a faulty lithium cell and will periodically flag an error. Above 2.5 volts, sodium ion is charged normally up to 3.65 volts.
