I suspect most of the solar controllers are very similar and made in China. Hopefully Renogy will have better quality control that the other 2 cheapies I got from Amazon/Ebay.....
I opened them up to check them out and found very iffy solder joints and some transistor legs they never bothered to trim. They were both working but I fixed them up and expect them to last a lot longer.
I picked up the small 10A Renogy because it had a setting for Lifep04 and I felt I would get a better response if there were any issues and I was using their controller. This is a portable system so not going to be throwing hundreds of watts into it at once.
Should this work out I will consider the 100AH battery for my truck camper when I get it. I prefer to do my own electronics. That way I know what I have, how it is wired and how to fix it Will keep everyone apprised with how this Renogy system works out
