I have used it to jump-start some LFP batteries that got too low. The continuous charge current is as advertised. The setup is straightforward. I have a variety of connectors/jumpers to connect to different battery terminals. It's nice to have the 240V cable that comes with it, but I recommend getting the 120V cable as well for convenience and flexibility if you plan to use it in this capacity.
I know of people using several of these permanently installed in parallel without issue on large LFP battery banks, but I have never done it myself. And I'm about to install a Chargeverter on a Conext system that can't seem to trigger a generator reliably, so I need a way for the owner to turn on the generator manually and have something start charging batteries that are below the Conext LBCO, no questions asked. The Chargeverter seems like a perfect fit. If the Conext system does start the generator successfully, the Chargeverter will just be another source (I will need to adjust the charge parameters of the inverters and make sure I'm not overloading the generator).
