How many amps between batteries that are wired in parallel?
If the batteries are identical, one battery provides half the current. If they are not identical, e.g. one battery is dead or missing, full 3A. If you connect two batteries together that are unequally charged, e.g. one full and one empty, any arbitrarily large current would flow to equalize the charge levels. Prepare with good margin and fuses.

Do two Lithium batteries in parallel double the discharge amps?
My own personal rule is two batteries, 150% current of one battery. So with two batteries each capable of 100 amps, with 2 in parallel, you can pull 150 amps, so even if there is a 50 amp difference, the high battery is only at 100 amps, and the low one is providing the other 50 amps. Go to 4 batteries, and now you should be safe pushing 225% ...
