Seeing this post in another thread:
I am thinking paralleling up my batteries would give me some useful benefits.
Firstly it will drain some from each (hopefully) rather than all from one, and of course offer me an increased operating time (I plan to use the battery power for doing some backpacking contesting too, which will be more current demanding than SOTA)
Assuming same age and capacity batteries like I have both fully charged, is it acceptable to just parallel them up?
I’ve had a mooch around the web and people seem to be doing it (as is @OE9HRV of course).
Normally when I have paralleled stuff up I have used balance resistors, or in PSUs, diode sharing. Clearly I don’t want to throw away power if it is not needed to.
