In reply to Gergely Dr. Orsi. Check page 8 of the datasheet. There is an equation to calculate R_ISNS based on the desired Imax-chg

In reply to mixos. Dear Mike, Can this pcb be modified to limit the charge current to 200-250mAh. I need a reliable charger for 6v 1Ah and 1.2Ah batteries. Couldn't find any commercially available one.

For 12V SLA battery charger please take a look at this project: https://www.electronics-lab.com/project/12v-sla-lead-acid-battery-charger-using-bq24450/

Hi,

I purchased one of these units and wanted to modify it to input a MAX 28VDC to charge a 12V 1.2Ah battery. The Battery part number is CP1212.

Is this possible? Can you help me?

Thanks
