Hi all,
Original miboxer C4-12 12amp charger plugged into mains, I inserted an 18650 and the fuse in the moulded mains plug went (3A, I had installed, the original was 13A, WAY too overrated for this charger :person_facepalming: )
I ordered some spare plug fuses and tried it on my experimental 12V DC solar set-up, it promptly blew the 5A fuse at the battery…
I’ve taken the cover off to access the circuit board, no obvious burns or damaged components, and advice to troubleshoot?
Thanks in advance everyone!
