Summary

If you often have to charge a lot of Li-ion batteries, the XTAR VC8S might be a good choice for you with its eight slots and powered by a USB-C port with 45 W USB PD. It also comes with helpful extra features like internal resistance measurement and a capacity test mode to check the performance of your batteries. To prepare them for storage, it has an storage mode that automatically charges/discharges them to 3.6 V.

NiMH batteries can be charged as well with the VC8S, but it only charges them with a fixed current of 500 mA and might terminate a bit early. That’s enough for casual charging, but if you want more control over the charging process, you might prefer a different charger.

Unfortunately the charging current cannot be manually set for each slot independently, only for four slots at once. If you rely on the automatic current selection, some batteries might be charged with a little too much current. This limits the flexibility of the charger when you want to charge different sizes of batteries at once.
