Safe battery charging?

[Acetronics2]

Hi, Keymuu

I guess others did not want you telling them they do not have enough experiance to answer you question.

Also, consider it's a PBP Forum ... not a general electronics Forum ...



Dave is here "close to the truth" ...

Just add to that all batteries have a Tempco ... and you'll have to trim the end-of-charge voltage depending on temp.

Now ... also remember "slow" charge and reasonnable discharge rates give the max. life duration to your cells.

For the end ... remember each cell has its particular capacity ... so it MIGHT be charged cell per cell. and voltage shouldn't drop below .8v ( for Nixx ) ...

For series assemblies ... a Schottky diode parallelled to each element is a safe precaution not to invert the polarity of one cell while discharging, ... or in use ...

The chargers might be able to recognize a cell voltage inversion ( very quick voltage drop of the assembly ) and , as soon as, turn to slow charge ...

But ... I did not hear about that, during all these years ...
