Working very well with sort circuit protection and over charge protection 👍

Working very well

Failed within 2 days

Failed within 2days of use, battery out terminal not giving 12 volt output after 2 days of use , hence i have to connect negative terminal to 0 volt point to get 12 volt output .

READ THIS REVIEW BEFORE USING IT OR YOU WILL KILL THE BMS!

Pros :1) Balance Charging2) Overcharge Protection3) Overdischarge ProtectionCons :1) It does not offer any overcurrent protection while discharging, the mosfets will simply explode.2) It does not offer any current limiting feature, basically if your battery is at 12.6v, it's cutoff is 12.75v, means if you connect it to a 10A charging supply when it is 80-90% charged, it will just charge the batteries with 10A till their voltage is 4.25V, and we all know if we give enough current to a battery no matter it's charged or not it's voltage will rise, so you need a charger to charge with this BMS.3) It DOES NOT HAVE A SHORT CIRCUIT PROTECTION, your BMS MOSFETs will simply explode, it's not made for short circuit protection.4) MOSFETs get hot and you need a cooling system to run this BMS at 40A.5) Charging voltage is 12.6-13.6V, means you CANNOT USE IT IN AN INVERTER, Connecting it to an inverter will simply kill the BMS because inverters charge batteries at 14.6V and sometimes 15V, this BMS will die at that voltage.6) This is a fragile BMS, your slightest stupidity can kill it.Things to keep in mind :1) Do not charge with current over 10A.2) Do not exceed a charging voltage of 13.6V or the BMS will die.3) Do not short circuit the output or MOSFETs will explode and BMS will die, not covered under warranty or replacement.4) After the battery is done charging, i.e., each cell's voltage exceeds 4.25v with an offset of 0.05 volts, the BMS will disconnect from charging and the BMS output will be from the load MOSFETs, which reduces the voltage by 0.3V, means if your battery is at 12.6V, it'll output 12.3V.5) If you apply too much voltage while charging the BMS will simply shut down.6) Once the batteries are charged, the BMS will start charging the batteries only after it's down to 4.17V per cell.7) This BMS offers only balance charging and if one of your cells is bad, the cell will simply discharge faster, and the overdischarge protection is activated when any one of the 3 cells go down below a voltage of 3.3v.8) Do not exceed the charging voltage of 13.6V as long as you don't wanna kill the BMS.9) Charge with a constant current and constant voltage of 12.9V for the best results, and once the pack reaches 4.15V per cell or 12.45V, reduce the current for better and more efficient charging.

Be careful.. while installation

I bought this bms for making a 12v 18650 lithium ion battery pack . And I make it too. It works perfectly fine for the time . But by mistake my circuit get short , In the product description they say the board having short-circuit protection, but it's not . The component on board crack and the output voltage drops . In other hand yeah this board save my batteries. But borad is dead
