B32M maximum voltage

Posted by: audiotek10 - 07-09-2026, 07:51 AM - Forum: DIY Project - Replies (1)

	The power supply is always shown as 12-24V I want to use this in a motorhome/RV and we have 24V LiFePO4 batteries. This can charge up to 28.8V. Is this safe with the B32M? How strict is the limit?
