hmmm... ok here's my thoughts on does added resistance of the FT batt holders only affect the longevity of the batt (i.e., the batt cuts out at a higher unloaded voltage)......
IMO the answer is no... unnecessary resistance in a circuit affects more than just the batt's unloaded cutoff voltage (loaded cutoff voltage will always be the same - for the dna loaded voltage cutoff will always be 3.1v).
And here's why... resistance and current are inversely proportional (Ohm's Law) - unnecessary added resistance in the circuit makes it more difficult for current to flow (decreases the amount of current flowing over a given time period) - which may put stress on components as well as cause a lag in the converter's response time.
When resistance impedes current flow, there is not only a voltage sag under load, but also a waste of power. For example, 10mOhm resistance at 10A wastes 1W and drops voltage by 0.1v. 60mOhm resistance at 10A wastes 6W and drops voltage by 0.6v.
You're most likely not pulling 10A though - maybe around 4 or 5A - so 60mOhm resistance at 5A wastes 3W and drops voltage by 0.3v. Wasting 3W makes for a fairly inefficient system. And causing the batt to excessively sag under load stresses the batt, will degrade it or may make it become unstable, and will need to be replaced sooner.
You'll not see this at the output with a regulated mod though - you'll see it only on output if the resistance is severe enough. But the converter requires a certain amount of input current in order to output it - with impedance to current flow on the input, the converter won't be able to operate as efficiently.
We parallel fuses to decrease the fuses' resistance so it won't affect current flow as much and there we are talking about reducing by minor mOhm values. So 60mOhms (or whatever the FT batt holders are adding to the resistance of the circuit) seems like a lot to me. It's like using 28ga or 30ga wiring for the input instead of 20ga what with the restricted current flow.

....I was way off....retested and the highest I got was 16w output.
