The proposed idea for this issue is to use two batteries and design a power management system such that if one battery drains below the threshold voltage, the circuit automatically switches power supply to the other battery and vise versa. Before the second battery depletes, the user will be prompted to replace the first battery and vice versa.
The Back-UPS puts out a stepped square wave, which the power supply can''t deal with and shuts off. Your Smart-UPS(unless it''s one of APC''s really cheap junk new ones) puts out a mostly pure sine wave, which the power supply can handle. The really old white Back-UPS''s tended to work better from what I''ve seen, but still aren''t …
In short – Yes, you can connect two power supplies together, but it''s not as simple as it sounds. Tapping into twice the power requires precision, the right tools, and a keen understanding of how …

When a battery cell is open-circuited (i.e. no-load and R L = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E.When a load resistance, R L is connected across the cells terminals, the cell …
No, you can''t put two supplies together in any way to add both their current rating and their voltage. This should be clear just from the power output alone. The 15 V 5 A supply can deliver 75 W. The 5 V 2 A supply can deliver 10 W. Both together therefore can''t deliver more than 85 W. However, 20 V at 7 A would be 140 W.

When a battery cell is open-circuited (i.e. no-load and R L = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E.When a load resistance, R L is connected across the cells terminals, the cell supplies a current I which causes a voltage drop across internal resistance R INT of the cell. Thus this internal voltage drop means …

The highest performance (most power efficient/coolest) method is to use a FET OR-ing setup. Their primary advantage is a near-zero voltage drop, limited only by the R DS(on) of the FET and current sense resistor (10 mΩ total resistance is fairly easy, but 1-2 mΩ if you really need).. Controllers for said systems typically use a low-value sense …
