“If possible it would be helpful to also have a column to separate which boards have a built-in or in deck battery vs external battery.” Hi Dave, thanks for reaching out. I had such a column in the beginning and decided to not list it anymore because I found it too hard to determine, whether or not a battery is easily swappable or not. Furthermore it depends a lot on the definition. Take e.g. a board that has 4 screws to fix the battery, rest is plug & play. To some extent all boards have “external batteries”.
