Wow, theres a lot of trail and error trying to get everything balanced to work effectively. Im looking for Dasboata for my new props and go from there
You should not take your batteries below 80% discharge. They got hot and puffed because you over discharged them. If you want longer runtimes you will need to parallel in another set or use bigger capacity batteries.
