One question I would like o ask @fwippers regarding off peak hours. Am I right thinking you have from 9.30pm to 1.30am to charge cheaply and are you planning on charging regulary to keep the battery topped up within these hours. The reason I ask is doesn’t it take about 9hrs to charge from 10-80%, or am I miss reading something.
Obviously it will depend on how many miles you do, for how often it needs charging.
