Standard Ni-Cd/Ni-MH Battery Pack Charger

They are interesting facts behind the concept of these Battery Pack Chargers.
Most undocumented fact, from the sellers of these products, this is of how we should select the most compatible product for our own application.

This answer it can be found, only if we check entire product catalog of the manufacturer (brand) that we are thinking to buy the product.
Ni-MH Battery Pack this translates to inline charging of several cells.
Minwa - China, this is an experienced manufacturer at this product range.

Long story in sort version.
It is very interesting the fact, that when the inline cells count this increases, charger DC current output, this specification decreases.
Bellow there is an interesting table, this helping at making a correct sizing choice.
Battery pack cells count / correct charger selection.

It also very interesting the information, that all tables stop at the count of 25 NiMH cells in series.
At this class of products, current limiting this is controlled in analog manner, due Maximum output current by Iron Core Size (mA) of the transformer. 

Additionally, for us having a professional class of bench-top adjustable type of DC power supply with current limiter, we can use this instead so to charge several cells at once.

We can use the table bellow, as guide for us setting up, the appropriate (Safe) voltage and current settings.
