I can report that the charge port does not show the voltage of the battery, it is connected through the BMS (battery management system) and only shows a low voltage. My voltmeter will be here tomorrow I believe, next I will look at the front light, for measuring voltage. I don't really want to cut into the wiring at the battery or battery mount as this may void the warranty.
I tested with a plug that fits the terminal, and the voltage is about .1v. I used to make camera parts so I have good collection of different plugs. This does not surprise me as this is an intelligent battery with a built in balancer and thermal protection using a BMS logic board. It is not connected directly to the cells. If it was then you would need a balance port and a n intelligent charger/balancer.
