“Been running 4 24v batteries in a 2S/2P 48V set up for a year now in an RV. So far so good. Have run them down to 30% on a few occasions and still very happy with purchase.”
Works as expected!!!Added to another pq 25.6v 100ah to my solar system for more capacity. Works great, no problems with these batteries!!!
