Phantom battery draws

What are "acceptable" phantom draws on our batteries?

With everything I can think of turned off in our trailer I get the following draws:
In "Use" mode: .36amps.
In "Store" mode: .25amps.


Thanks so much!

I am also wondering what is normal. My 19' is drawing between .1 and .2 amps in store mode. I have a Trimetric battery monitor which has minimal draw, and probably the propane detector. I don't know what else is on.

The use/store switch itself has a small draw.

If installed, the subwoofer is on all the time. We put a "lighted hen on switch" in the 12Vdc power line to the subwoofer.

I have about 150mA as a normal parasitic draw when the switch is disconnected. I moved my propane detector so that it is also off. On my unit, the brake actuator board takes a bit and my solar controller are active. Also I was told by Bogart that the Trimetric consumes about 10mA when the display is off.

Thank you everyone for your comments. I am going to be bringing my AS next week to the folks who installed our lithium battery pack and solar panels to take a quick look at what the parasitic draws are.

I will report back on this thread with my findings.
