Hi guys,

If an optimal charging current lies between 0,1 and 0,3c of rated Ah (*right?), why is there no charger with a variable current limiter?

*is the minimum charging current really 0,1c or can you go lower?

Cheers.

Here it says you can quickcharge a leadacid battery, if you use a good charger:

Any thoughts?

The maximum charging current is adjustable.

Here is a 30A rated MPPT controller.

The maximum charging current can be adjusted to whatever you like. Here I have adjusted to 1A
