    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:I bought 15 of these charge/discharge protective circuit boards last year and found that they all worked well. I fitted one to each battery in sets of 4 and also bought DX Kapton tape, SKU5442 to insulate them and bind the cells together. I ordered an extra 3... Read more

    Involvement:General (knows how to use it) - Ownership:more than 1 month Pros:Discharge cut off protection below 2.75v or 10A. Cons:Reset not automatic even when all voltages removed. I've found the best method is momentary short of the neg (battery) to neg (output) via a push button switch or springy tab solder to board. OtherThoughts:Can be use... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:Good PCB, good quality factory soldering. Also good solder pads, easy to use. Terminal voltage rating not very good, but acceptable. Short circuit protection also works well. Cons:Low work current in this version - about 3,5 - 4A max. I need about 7-8A, so las... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Perfect form factor for 18650 laptop cells. Good price Nicely sized connector strips. Cons:The rated 10A is WAY overkill for single cell usage even if it does trip before you get there. No gasket or washer, to keep it properly spaced on the bottom of the cell... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:This protection circuit fits on the negative (-) side of standard 18650 lithium cells found in laptop batteries. It actually has 3 wires in the shape of thin stripes. The positive wire is the long one. It only taps the positive terminal of the battery. The sho... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:Really cheap protection circuit, SAVED MY LIFE A FEW TIMES and prevented the battery from blowing up when I plugged it into a cheap china made faulty charger. This is a must get for all 18650 batteries. Cons:Makes the battery longer than the standard 18650 size,... Read more

It couldnt run my v... Read more

    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 su... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:Simple and effective PCB. I use it with an old-cordless Screwdriver (KC9036 from Black & Decker) which was working with a NiCd destroyed battery. Two 18650 cells and this circuit and returned to live!! No more discharged screwdriver when you need it! Cons:It wou... Read more
