How to trigger battery charger off at 80%
Hi guys, I am charging my ebike battery with the Shelly plug S gen3 and need it to charge it to approximately 80%. Just need to be sure it won't charge fully.
I want a scene or anything which make this possible.
However, my battery is charging 72W/h for 8 hours long for 100%. There is not Wattage drop in the last phase so I can't setup a trigger ona a certain Wattage to stop charging earlier.
And since there is no voltage monitoring, I only have the timer option to setup a timer for 6 hours trigger time (appr 80% of 8 hours).
The problem is that the battery level is on very very different levels after use a couple of days so I can't use 1 timer for this. I want to press the physicall button on the Shelly and forget :)
Is there a way to achieve this (charging to appr 80%) or any other way?
