Product works exactly as advertised, it took me a while to get it correctly mounted and wired in. I tested it on the bench and under ideal bench test condition exceeds the advertised values and outputs up to 25A!
Installed I do see 25A but I'm assuming as the unit generated heat it throttles back the current. I am extremely happy with the purchase!!!
I did however think I had ordered the one with the Bluetooth but realised once it arrived that I had mistakenly ordered the non Bluetooth version. Not the products fault nor the retailer I didn't read the description correctly.
The non Bluetooth does not switch on when the supply voltage reached a specific voltage, however it relies on an addition switched input.
I managed to find a low voltage cut out module and adjusted it to my specific cut in and cut out voltages and the whole system appears to be working exactly as I had intended.
I have not done a thorough test on it but it is wired in and working exactly as it should.
