Re: Normal non cc/cv PSU with a normal cc/cv charger to increase volts and still get cc/cv charge to battery

I run HP 550 12.6v 40amps or so and a meanwell 24 at 10amps turned up and get 42v @ 15amps . I thought the 10a meanwell would have limited the ampage more. Works well 2yrs. Is this what you are asking?

Which you should always check with new items they're all made in China at Red doesn't mean anything white doesn't mean anything and black doesn't mean anything check it.
