My charger is reaching 6.0 amps (which is about all it can do on 6S), so the impedance of the charge lines is not an issue. The charger is the Turnigy Accucel 8150. So far that's the only charger I've tried.
I did change the wires from about 4 feet long to about 7 to 8 feet in this last upgrade, and they are 18 gauge red/black Radio Shack speaker wire. This reached 6.0 amps during my charging test.
Depending on the charger, the results might be different. Which charger, and what length of what gauge wire did you use?

Temp < T1: Throttle left alone
T1 < Temp < T2: Throttle is progressively limitted to less than full throttle.
T2 < Temp : Throttle Off.

Cars used to have various cut offs so the engine stopped before it was damaged. Later it was decided that stopping the motor was dangerous and confusing. Modern cars always have a light or buzzer but no cut off.
I remember some of the early Vespa sized e scooters had a series of safety interlocks including one where the scooter would not run with the kick stand down. This system caused more harm than good and resulted in a bunch of unsatisfied customers.
I think blinking light and or buzzer would work well and add little complexity and cost. Whatever you decide to do I would buy one of these circuits when they are available.
