Battery Charging
Probably a dumb question but here goes..When you have other things attached to the battery posts like an inverter, battery monitor etc. and then attach a charger to the battery posts or use the conver...

I will use my own RV as and example
But basically ... When you are on Shore or Generator power and you use 12 volts, be it for Lights, Fans, or whatever.. The power comes FIRST from the converter.. This reduces amps for charging.. Then if you need more power than the CONVERTER can pump out. power comes from the batteries.
Progressive Dynamics 9180 capable of up to 80 amps output
Over 500 amp hours of battery STORAGE.
Multiple loads including lights ranging from Small LED loads (say 2 watts) to 20 watt incandascent lamps (roughly 1.5 amps) and my #3 big load, a Kenwood TS-2000 (100 watt 2-way Radio) #2 is the furnace, #1 is the inverter. But on shore power the inverter is NOT a load.
Now when I click Transmit that TS-2000 can suck close to 15 amps
On shore power that comes from the CONVERTER, so now I only have a max of 65 amps for battery charging. (Less what the lights and fans and other stuff are pulling) I will never have the full 80 amps for battery charging.
In fact, though the factory put in an 80 amp converter.. Max safe charge, as delivered (I've upgraded the battery bank) was 70 amps.. So the factory took that into account in designing my RV.
