LABTEST Mark V
Standard settings, both radios on and normal traffic.
load may vary on config.
test voltage and draw
5v - 0,6A - 3W
7,2v - 0,4A - 2,88W
9v - 0,32A - 2,88W
11,4v - 0,26A - 2,96W
12v - 0,24A - 2,88W most efficient rating, since a battery will usually have deeper discharge at this voltage.
13v - 0,23A - 2,99W, not recommended at thislevel it begins slowly drawing more current. stressing the regulator
this shows the efficiency area of the input.
example and theoretic battery calculations under these conditions.
12v x 8400mah - 100wh/2,88w giving 35hours
Remember LVC circuits on lithium polymer and lithium iron phosphate cells so you dont brake em.
protected lithium ion 18650 cells is recommended if you dont have lvc, cheap and you can find them everywhere.can also be bulk charged.
now you can calculate batteries with more accuracy
