SkyRC MC5000 Battery Charger and Analyzer

The SkyRC MC5000 has six operating modes: Charge, Discharge, Storage, Cycle, Refresh, and Break-in . You can use it to normally charge batteries, perform controlled discharges, prepare them for storage, run charge/discharge cycles, refresh cells, and condition new or long-unused batteries.
 
The MC5000 can charge the following battery types/chemistries  and battery sizes:
Li-Ion,  - Li-Ion HV (High Voltage), -  LiFe (LiFePO₄), -  NiMH (incl. eneloop), -  NiCd ,  - NiZn ,  - RAM (Rechargeable Alkaline Manganese),  - LTO (Lithium Titanate),  - Na-Ion (sodium ions).

NiMH / NiCd / eneloop: AAAA, AAA, AA, Sub-C, C, D* (size D max. two at the same time)

Li-Ion / LiFe / Na-Ion etc.: 10340, 10440, 14500, 16340, 17500, 18350, 18500, 18650, 20700, 21700, 22650, 26500,
26800 (only without PCB)
*32650, 32700 (maximum two at the same time)

Additionally, the MC50000 supports many other intermediate formats, as long as the cells, which are approximately 32–80 mm long, fit into the charging slots (a total of 44+ sizes according to the manufacturer).
From a diameter of  29 mm upwards, only a maximum of two batteries  can be charged simultaneously due to their width (the other two slots can then only be used with smaller cells).
