not for LiFePO4
After initial issues with the ground cable run being bolted to the tub instead of the chassis it worked pretty well. Main issue which will lead to its replacement is that on LiFePO4 settings the alternator input cuts off at full charge (good) but does NOT come back on until battery is discharged to under 30%. A couple of times we've pulled over for a day or two & found the battery near or actually shut down. The controller will not unlock the shut down either. There is no provision for a top up charge in LiPo mode; it is there in the other modes & it would be fine for deep cycle or AGM but not ideal for LiPo. The solar charge input seems to be fine but parked under tree cover it needs a long lead to get the panel in the sun (of course) & it needs to be moved regularly. There is also no display to tell you what is the state of charge.Read full review
