Replacement BMS

This was a replacement BMS for faulty unit that was supplied initially. This works perfectly and makes me a happy cutomer

Works as it says on the box.

I have 2 of these for almost a year and have found they balance all cells in both banks within 2 millivolts. The active and passive balancer really does a good job. Installation is easy and software is straight forward to use and adjust by bluetooth or remotely by internet or phone.. Support from LifePo4oz has been excellent. I am using two 250Amp models with two 12v, 304Ah EVE cells on my boat with 1000watts of solar. I can run my Microwave, hair dryer, induction cooktop and 4000watt, 8000watt peak inverter with ease.
