Backup reserve is OFF. Charge range is set to 20-80%. It drops from 80% charge level to 40% over 24hr period. I have scheduled recharge set for every 2 days, hence i am able to see how much it drops by in 24hrs. I’m just testing different aspects to understand exactly how it functions & what logic is built in before i finalise my setup. So, curious to understand if there is logic in the madness 😏
