2in1 AutoBattery Buffer Backup

2-in-1 Automated Surge Protector Buffer Backup Battery (95% capacity) integrated with adjustable overvolt switch that works with/without A.R.C, featured in the Hourglass. It charges 10% on idle if <95% capacity and discharges when > 95% by hot swapping charging dock (total 400w) to battery from power grid. The 400w charging dock is within a 1000w relay alongside 1000w oxygen generator hence no power spike/drop (constant 1000w draw) whenever hot swapping it to battery/power grid. Battery will try to stay close to 95% to ensure enough capacity for backup power and not being completely full to allow battery buffer to work. When reactor Power < Load (whenever load spikes and power is catching up or when reactor is out, charge rate will always be at 0% preventing input feedback loop and ensure no wasted charging load.

• It only charges 10% at idle when charge is below 95%, current BATTERY_RECHARGE_RATE is 0 (idle state) and when power >= load
  
• Oscillator frequency can be reduced to extend recharge time when load drops, but found value of 3 to work best since it's somehow mostly in sync to instantly adjusts charge_rate while other numbers tends to have a very short delay (you will see a very short sudden drop in graph instead of smoother lines).
  
• It charges at 10% on idle since having higher values will reduce battery buffer capability so the lowest value 10% is used to still have 90% of buffer. However 10% may be too slow to charge the battery when on low charge thereby a fast charge override switch is also added to the system (tho it will disable battery buffer in its mode)
  
• Make sure fast charge switch disables battery output otherwise oscillations feedback loop may occur.
