That is very minute drop for that run. If it’s not getting warm you have a good connection. It should drop from that pretty quick. Just check about every thirty minutes and you should see it dropping as batteries start to charge. One other thing. As they are charging use the feel test to see if battery cases start to get very warm. That is not a good thing and could tell you you are charging to fast. Also pull your caps and look for bubbling. I don’t think your going to have a problem now though.
