good buggy product

Some bms arrived without led installed on it
If the voltage meets the overvoltage there is no way to make the balance unit work and the battery does not make balanceunteel the overvoltage relase voltage is met (but can not be met if there is no balance).
charger voltage must be set in the way all cells meet the balance threshold voltage but not the overvoltage condition.
in the last four items the external temperature sensor is useless because reads 70 celsius at room temperature.
current readings are made using discharge mosfets rdson but no protection is added do avoid mosfet failure to burn the processor. if a large spike current is made (connecting a light bulb for example) when the i2c is connected the processor blows

to understand this I burnt several bms units.

if You do not make these fails the bms works properly and the software is decent

Smart BMS experiences

With the USB connection and available software it is a nice BMS to adjust to your own specs. Most BMS'es are fixed to certain charge and discharge voltages which are not optimal for long life use. This 1 is when setup properly. Had random failure on 2 of them but will keep track of the next ones which are coming so I can get a good feel of the quality.
