In my personal opinion, a battery gauge on the board has so little practical value that it falls in the “looks, appearance, eye-candy, and svelte” category for me. I don’t ever add them anymore. Plus, it’s one more place for water to enter.
this, plus you can plug in one of these into the charge port
or use a bluetooth solution to just look on your phone. If you need to check at all. Properly adjusted ESC cutoffs mean you can feel the battery getting low anyway.
So there are like 4 separate reasons you don’t really need a battery gauge on the esk8 imho, despite it seeming like a ludicrous notion at first. It’s completely unnecessary.
