    Bought these to protect old laptop cells, this is my second batch from DX.COM and they appear to work as described, its been a few years without any problems. but will know more as time goes by. Protection is needed for li-ion batteries and for this price its well worth it. Use kapton tape for if... Read more

    Works as intended. No drawbacks.

    Хорошая плата для защиты от переразряда аккумуляторов типоразмера 18650. Удобная вещь для модернизации аккумуляторов используемых в фонарях и прочих устройствах, где требуется контроль за разрядом аккумулятора. Рекомендую к покупке.

    A good choice to DIY projects, to reuse laptop cells, old mobile batteryes or protect unprotected cells.Works fine in flashlight projects, but the overcurrent limiting is so low (cca. 3A)... not 10A.Must reshape if you want to use in handy tool. The overcharging protection very useful (like the... Read more

    Pros: cheap, does the job Cons: Only has one FET. Needed to change the value of R1 resistor to get current protection working.

    Impression:does the job;

    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 charge/discharge protective circuit 4...

    This can be easily attached to any unprotected 18650 battery. Provides protection from overcharging, over discharging, short circuit etc. I have a bunch of 18650 units and I tried it on one of them. Works as advertised. Can not see any specific cons really. Maybe the cuttoff voltage should be 3v... Read more

    Discharge cut off protection below 2.75v or 10A. 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. Can be used to protect series wired multi cell batteries...

    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. Low work current in this version - about 3,5 - 4A max. I need about 7-8A, so last time i brought this PCM 2x in quantity I... Read more
