Review on 🔌 Renogy 12V 50A Multi-Stage Charging DC On-Board Charger with MPPT for Gel, AGM, and Lithium Batteries by Kevin Apriando

I consulted them before purchasing Solar Panels - Lithium Batteries - Charge Controllers - BT-2 and remote battery indicator are all Renogy products. - Hired a professional boat electrician to install - poor instructions - can't get the charge controller to charge the starter battery as advertised and can't connect the blue tooth module or remote battery panel and despite 12 hours of waiting and dozens of emails working - you pull it in. You can't hook up the system first as described in the manuals and/or diagrams sent to me. I've made a dozen help requests, but no help - - but I've been trying to get everything working for over a month. BAD DEAL
