Right i have this problem, i have a protection pcb module for 18650 lithium ion batteries, connected them in series as per diagram and i get 11.8V across the B+/B- terminals ok, i get nothing at all on the P+/ P- terminals, so if i measure between the B- and P- they are commoned, ..
I am right in assuming that the P+/- terminals are for supplying the charge voltage to the pcb, or is this where i connect the load,
Even if i connect a 12 to 15v supply to the P+/- terminals to charge them, and measure the current i get 25 microamps??
Has anybody used these pcbs before, and how to use them to charge the battery and use it to power a load?
