Tycon Systems TP-SCPOE-1218 Poe & Solar 8A Dual Input Battery Charging Controller - 12V in and 18V POE Out

I'm in the process of building a small and portable solar power system with lithium ion batteries for that and in the solar charge controller that can be able to control the charge for my lithium ion battery pack here today I will test these charge controllers to show you which one is the best for this project this is my homemade 12 volt 3 s 2 P lithium ion battery pack I need a solar controller for this I did a search for a little my own solar charge controller and the only thing that came up is this this is a 3s lithium ion charger it's cheap and it gets the job done but this thing is actually cheap I mean there's a couple of LED indicator lights and that's it and it can only support up to three amps max this controller here has a screen that shows the actual voltage of the battery and it has a couple of USB ports so I can charge other USB devices it's a lot more useful than this smal
