Uprated the cables to 35mm² to start testing the battery. In this first charge I pushed the state of charge (SOC) from 25% to 50%, took about 1hrs 13mins. Indicates that a full charge may be just under 5hrs. Also using this 25% charge suggests a 100AH full capacity. In general, happy charging is working. Nice to find some interesting numbers from this test run. Also happy charger runs like a boss… even if the fans are a bit loud.
