RV AGM batteries

Recently bought 2 off 140 AH AGM Deep Cycle batteries for the RV. Purchase, pickup and installation were a breeze. System is all charged up and seems to be working fine. Once the COVID19 pandemic has settled might be able to give them a real test. At the moment just happy about the way it is. Thank you Aussie Batteries & Solar.
