As described. Appears to be well constructed.

Have not thoroughly tested yet but the quality looks very durable. It's got a thick rigid layer over the cells to protect them and folds nicely

The first thing to know about this controller is that it is smart enough to work correctly with lead acid or lithium-ion batteries. Important because the two types of batteries have very different charging algorithms. This controller will be used in a portable setup that is intended to charge lithium ion batteries from a couple of smaller portable solar panels. Having the ability to switch over and charge the lead acid battery in The event it is needed is an extra bonus from my perspective.

The set up and working is clear and simple; the screen is easy to read. Does the job and makes short work of charging my various 13.8 V LiFEPO4 batteries.

How well it will last in regular use is an open question, of course which only time will tell. Are any unexpected negatives this review will be updated.

I had this professionally installed. After watching several YouTube videos that show how easy the install is, I thought it is above my pay grade and I’m satisfied I did. I switched out the circuit breakers as well and installed a 2000 watt inverter. $1100 for the extra parts and labor. This not a project you want to cut costs on.
