Review on LST Truck Battery Charger Maintainer: Auto Trickle Deep Cycle Charging For Automotive, Marine, RV, SLA ATV AGM Gel Cell WET Lead Acid Batteries by Chad Dahl

I bought this charger and for the money I was hoping for a good charger. When I took it out of the box and hooked it up it would not work and constantly showed fault. I tried it several different charging profiles and all the charger would do is show fault light on. The directions are terrible. I contacted the company and they said I was not hooking it up correctly and I sent them pictures and then they said try reversing the leads. I did this and it now appears that it may work but I don't trust it and would not leave unattended. Also putting red on negative and black on positive is not correct and could lead to issues.
