I need more battery storage with all the cloudy, rainy days and decided to connect 4 of the Wattcycle 280Ah smart minis in series. I went with simple buss bars that I fabricated and 3d printed some safety covers that press on the exposed ends to keep it clean. Hopefully this will work with the Vatrer rack batteries that I no longer trust after 2 random shutdowns of one at a higher SOC. I may eventually just go with another 12 of these if they work out and Have 4 serial / 4 parallel giving me 57,344 total system watts on a budget. At this point it seems the 314 Ah version just released may be more economical. Hard to keep up with how fast these batteries are evolving.
