A simple little protection board for low current (3A or less draw) systems using 2 series lithium cells. The type / size of cell is not important but the chemistry, must be lithium. The Negative ( -) end of the first cell is connected to the PCB terminal marked B- The connections between the (+) positive end of the first cell and the (-) Negative end of the second cell is connected to the PCB terminal marked BM (battery middle?) The (+) Positive end of the second cell is connected to the PCB terminal marked B+ The connection to the load / charge is made to the terminals marked P+ (7.5V nominal) and P- (GND Negative) Operation is simple. If either of the 2 series cells exceeds the upper voltage limit or drops below the lower voltage limit, the load / charge connection disconnects. The load / charge connection reconnects when the voltages are normal again. This may be the basis of a simple charge limiting circuit and over discharge protection circuit. The board is well made and works as it should. I hope this clears up some of the questions raised.

πολύ καλή σύσταση 🤝🏿
comprato per proteggere le batterie esterne li ion per il modulo esterno r9m. i pad da saldare sono delicati. A 385° si staccano e si spostano.
Γρήγορη παράδοση
good quality, it's working, very small dimensions
Έφτασα πολύ γρήγορα, αλλά δεν το δοκιμάζω, αλλά φαίνεται καλό όταν το δοκιμάζω. Θα το σχολιάσω περισσότερο
nice and small
O K Πολύ καλό.
