Worked as expected!

These are not bad considering all the odds. Worked as expected for 18650 Lithium Battery with operating voltage of 3.7V in 1S configuration. Please note that this Protection Board is not suitable for high current applications as each of these super tiny PCB boards can deliver up-to 2.5Ah max. If your 1S 3.7v battery has more capacity and you would like to draw power you can connect two of these in parallel for about 5Ah current rating.The main reason for having these boards is primarily for short circuit protection. Calling these as "BMS" is little bit of an overstatement as it does not really do Battery management as one would think other than basic short circuit and over-voltage & over discharge protection.For the asking price I do not think there is any room for complaints. Rating them with five stars!

Do not recommend

Had 3 of these connected in series with no load connected, and they complete drained my 3x 18650s (drained to below 2V) after a few days. The HX-1S-3576 6 MOS version seems to work better (has much higher current output, but more expensive) but Amazon is currently showing as no available: https://www.amazon.com/gp/product/B07QLMK9HS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
