[QUOTE="AAH, post: 98217, member: 543"] Welcome to ACL Buck converters and most power supplies don't play well with others. Meaning that when you have both the -ve and +ve connected you can get very unexpected results. Due to slight voltage variations 1 supply may be attempting to supply all the current and others doing nothing. Based on the fact that you're only running 2 strips and the fact that a single strip is designed to not need power injection I would do away with 3 of the 4 buck converters as I don't think you'd need the wattage (not knowing exact strip specs though) and running extra ones is just going to pull more juice out of your battery as they are more efficient at higher loads than at low loads. I would run a single buck converter at the join between the 2 strips. The additional ground connection wouldn't hurt but it probably isn't necessary. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
