Good protection – Charge/Discharge Protective Circuit Board for Rechargeable Li-Ion Batteries (17.4mm*1.9mm) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
Cheap (considering free shipping with only one piece of it) Small, compact form (fits 18650 cell)
Cons:
Cutoff voltages could be more...considerate. I'm afraid the battery taken to these voltages will die fast - but IT IS ONLY PROTECTION - not charger. It is supposed to be the last protection against fire, explosion... when normal charger breaks or when something short-circuit the cell
Other:
After connecting to battery you have to "kick it" with charging voltage to activate.
Bottomline:
Cutoff voltages can be seen in my video. Good as protection circuit - not charger!!!
